RESUMO

BACKGROUND: High infection rates have been reported in hand procedures using the wide-awake local anesthesia no tourniquet (WALANT) method, causing some to question the validity of this approach. However, little evidence exists surrounding the direct use of WALANT compared with monitored anesthetic care (MAC). This study was conducted to directly compare the postoperative infection rates of carpal tunnel syndrome (CTS) and trigger finger (TF) release surgeries performed under WALANT and MAC. METHODS: A retrospective study comparing postoperative infection rates between patients undergoing CTS and TR releases was conducted. Our primary outcome measure was postoperative infection. Our secondary outcome was postoperative complications. Comparative statistics were used to compare means of infection between the groups. RESULTS: A total of 526 patients underwent CTS release (255 with WALANT and 271 with MAC), and 129 patients underwent TF release (64 with WALANT and 65 with MAC). Patients undergoing WALANT and MAC were statistically comparable in terms of sex, smoking status, diabetes, and American Society of Anesthesiologists physical status classification. In patients undergoing CTS release, there were no infections with WALANT and 6 infections (2.2%) with MAC. In patients undergoing TF release, there were no infections in either group. There were similar rates of complications in patients undergoing WALANT and MAC for CTS and TF releases. CONCLUSION: There was no increased risk of infection with WALANT compared with MAC in CTS or TR surgeries. These surgeries can be safely conducted with lidocaine and epinephrine without a concern for increased risk of infections or complications.

RESUMO

Introducción: La lesión del nervio ciático puede ocasionar desde parestesias e hipoestesias, hasta dolor neuropático severo y parálisis. La neurólisis suele mejorar la función, el dolor y la calidad de vida de los pacientes. El objetivo de este estudio fue evaluar los resultados clínico-funcionales de una serie de pacientes con dolor neuropático por lesión del nervio ciático que no respondieron al tratamiento conservador y fueron sometidos a neurólisis. Materiales y métodos: Se analizó retrospectivamente una serie de pacientes sometidos a neurólisis del nervio ciático mayor entre marzo de 2009 y junio de 2018. El dolor pre- y posoperatorio se evaluó mediante la escala analógica visual y la escala de Likert. El tipo de dolor posoperatorio se evaluó con el cuestionario DN4 y la calidad de vida relacionada con la salud, con el cuestionario SF-36.Resultados:Se incluyó a 8 pacientes. A los 32 meses de seguimiento promedio (rango 14-66), el dolor había mejorado notablemente (promedio de 3 y 1,88 puntos en las escalas analógica visual y de Likert, respectivamente). El cuestionario DN4 arrojó un promedio de 3,75 puntos (rango 2-7). Según el SF-36, la "salud física" fue la variable con peores resultados (promedio 30,15).Conclusiones: La neurólisis, cuando se indica a pacientes con mala respuesta al tratamiento conservador, es un método que alivia el dolor y mejora la calidad de vida de los pacientes con dolor neuropático secundario a una lesión del nervio ciático.

Introduction: Sciatic nerve injury may cause paresthesias and hypoesthesias, severe neuropathic pain, and paralysis. Neurolysis can improve function, pain, and quality of life for these patients. The objective of this paper is to evaluate the clinical-functional outcomes of a series of patients with neuropathic pain due to sciatic nerve injury that was refractory to conservative treatment in whom neurolysis was performed. materials and methods:A retrospective case series of patients operated on for neurolysis of the greater sciatic nerve between March 2009 and June 2018 was analyzed. Preoperative and postoperative pain were evaluated using the visual analog scale (VAS) and the Likert scale. The type of postoperative pain was evaluated using the DN4 questionnaire, and the health-related quality of life was measured with the SF-36 questionnaire. Results: Eight patients were included. All patients evolved with a notable improvement in pain, with an average of 3 and 1.88 points on the VAS and Likert scales, respectively. The mean follow-up was 32 months (range 14­66). The DN4 questionnaire showed an average of 3.75 points (range 2­7). According to the SF-36, "Physical Health" was the variable with the worst results, with an average of 30.15. Conclusions: Sciatic nerve neurolysis in patients with neuropathic pain due to sciatic nerve injury and poor response to conservative treatment may improve pain and quality of life.

RESUMO

Introducción: La artritis inflamatoria puede conducir al síndrome de caput ulnae con desviación radial de la muñeca y los meta-carpianos. El tratamiento es la artroplastia de rescate de la articulación radiocubital distal y la reubicación del tendón del extensor cubital del carpo (ECC). Sin embargo, puede ser débil para corregir la desviación. Clayton describió la transferencia del tendón del extensor radial largo del carpo (ERLC) al ECC. El objetivo de este estudio fue comparar la corrección de la desviación radial de los metacarpianos en pacientes operados con transferencia del ERLC al ECC o sin ella. Materiales y Métodos: Estudio de cohorte retrospectiva en pacientes con artritis reumatoide y síndrome de caput ulnae, sometidos a tenoplastia del ECC con ERLC o sin este procedimiento. Se formaron dos grupos: pacientes con transferencia (grupo A) y sin transferencia (grupo B). Se calculó la corrección del ángulo de Clayton comparando las medidas preoperatoria y del último control, y se compararon los resultados. Resultados: El seguimiento promedio fue de 28 meses. El ángulo de Clayton preoperatorio promedio era de 44,54° (DE ± 7,52) en el grupo A y 60,24° (DE ± 12,28) en el grupo B (p = 0,001). El promedio de corrección fue de 6,57° (DE ± 4,11) y 0,95° (DE ± 9,17), respectivamente (p = 0,026). Conclusiones: El nivel de corrección fue mayor en el grupo A. No obstante, si bien ambas técnicas lograron mejorar el ángulo, el grado de corrección podría estar supeditado a la magnitud del ángulo preoperatorio. Nivel de Evidencia: IV


Introduction: Inflammatory arthritis can lead to caput ulnae syndrome with radial deviation of the wrist and metacarpals. Treatment includes salvage arthroplasty of the distal radioulnar joint and relocation of the extensor carpi ulnaris (ECU) tendon. However, the ECU may be too weak to correct the deviation. To strengthen the ECU, Clayton described the transfer of the extensor carpi radialis longus (ECRL) tendon to the ECU. The aim of this work is to compare the correction of the radial deviation of the metacarpals in patients with and without transfer of the ECRL to the ECU. Materials and Methods: Retrospective cohort study. Patients with rheumatoid arthritis and caput ulnae syndrome, treated with ECU tenoplasty with or without ECRL, were included. The patients were divided into two groups: ECRL to ECU transfer (group A) and no transfer (Group B). The correction of the metacarpal-radial angle (Clayton's angle) was calculated by comparing the measurements before surgery and at end of follow-up, and the results obtained were compared. Results: The average follow-up was 28 months. The preoperative Clayton angle was on average 44.54° (SD ± 7.52) in group A and 60.24° (SD ± 12.28) in group B (p = 0.001). The correction average was 6.57° (SD ± 4.11) and 0.95° (SD ± 9.17) for group A and B respectively (p=0.026). Conclusions: The level of correction obtained was higher in group A. However, although both techniques managed to improve the angle, the degree of correction could be subject to the magnitude of the preoperative angle. Level of Evidence: IV

RESUMO

The deficiency of the triceps tendon has been considered a relative contraindication to performing a total elbow arthroplasty. One of the conditions that may compromise triceps integrity is the presence of an olecranon non-union (ON). In this scenario, the placement of a total elbow arthroplasty in a patient with end-stage elbow arthritis is a complex problem to be solved. The aim of this study is to describe the surgical technique for the placement of a TEA in the context of a previous ON and to report the results of three cases. Surgical technique: the focus of the nonunion is identified, and the olecranon fragment is proximally reflected with the triceps tendon to allow accurate exposure of the medullary canal of the ulna and easy access to the joint. With the elbow in a fully flexed position, the previously assembled test prosthesis is placed and the proximal ulna fragment should then be reduced to match the distal ulna. Osteosynthesis with a tension band technique was performed at 45° of elbow extension. A non-absorbable Krackow suture (Ti-Cron 2-0) from the triceps's tendon to the hole of the wire in the distal ulna is applied to decrease the triceps tension traction. Bone grafting is performed when a persistent gap is present at the fracture site following reduction. This technique enables us to achieve a stable elbow with little pain and maintains the extensor apparatus's continuity.

RESUMO

PURPOSE: The objective of this study is to evaluate the effect of absolute stability (AS) versus relative stability (RS) performed through a minimally invasive plate osteosynthesis (MIPO) in AO/OTA 12A1 and 12A2 fractures on healing and the time to radiographic union. METHODS: This was a retrospective cohort study of all patients treated with plate fixation for AO/OTA type 12A1-A2 fractures at a single institution. Patients were grouped according to the type of stability used in their surgery. Time until radiographic union was estimated using the Kaplan-Meier method, which was compared by long-rank test between both types of surgical techniques. RESULTS: A total of 70 patients were included in this study with 35 patients in each group. The median follow-up was 9 (IQR 6-14) months. The median time to radiographic union was significantly lower in the AS group than in the RS group: 12 (interquartile range (IQR) 10-14) weeks versus 18 (IQR 16-19) weeks, respectively (p < 0.001). Non-union was seen in two cases (7%) in the relative stability group. Three patients in the RS group developed a post-operative radial nerve palsy. CONCLUSION: The main finding of this study is that the median time to radiographic union was significantly shorter in the patients treated with AS compared to those with a RS technique. These findings support the recommendations of the AO foundation in that simple metaphyseal fractures (type A) that require surgical treatment should be treated with an AS construct. RS techniques should be reserved to multifragmentary fractures where fragment preservation of blood supply is paramount.

RESUMO

Background: Volar locking plates have provided the capability to repair both simple and complex fractures. However, complications related to the inability to fix or to maintain the fixation of some fracture patterns have been reported with volar locking plates. The purpose of this study was to evaluate the results of dorsal plating treatment for specific pattern of fractures. Methods: Patients with distal radius fractures were retrospectively evaluated. Inclusion criteria for this study were those related to the patient and treatment (adult patients, internal fixation with dorsal plating, a minimum follow-up of 12 months), and those related to the fracture pattern (displaced central articular fragment, volar distal fracture line not enough to allow volar fixation, displaced dorsal-ulnar fragment, dorsal partial fractures, combination of these patterns). Clinical outcome information including active range of motion, radiographs, PRWE and DASH questionnaires were collected. Complications were recorded. Results: During a 6-year period, 679 distal radius fractures were treated with open reduction and internal fixation. Of these, 27 patients fulfilled the inclusion criteria. Patients were examined at a median of 34 months' follow-up. All but pronation, supination, and radial deviation had a statistically significant difference compared to the opposite side. The median score on the DASH was 4.5 and 3.2 on the PRWE. No patient suffered loss of reduction during the follow-up nor were tendon ruptures recorded. Conclusions: Although most of the distal radius fractures can be treated with volar locking plates, almost 5% of them present specific patterns that are amenable to treatment with dorsal fixation, without postoperative loss of reduction. These specific patterns are: (1) displaced central articular fragment, (2) volar distal fracture with less of 1cm distance from the distal volar edge of the radius, (3) displaced dorso-ulnar fragment, (4) Barton's fracture, (5) combination of these patterns.

RESUMO

El síndrome de Achenbach es un cuadro de baja incidencia y de etiología idiopática. Se caracteriza por la aparición aguda de coloración azul digital sin un episodio desencadenante, imitando a un cuadro isquémico, pero, al contrario, el síndrome de Achenbach se autolimita sin dejar secuelas. Se presenta una mujer de 75 años que consultó en la central de emergencias por dolor y cambio de coloración violácea del dedo índice de su mano derecha, de inicio súbito. Los estudios complementarios no aportaron información relevante. Se administró un tratamiento sintomático y se logró la resolución completa del cuadro. La anamnesis y el examen físico exhaustivo tienen un rol fundamental para sospechar este cuadro y los estudios complementarios se reservan para descartar otras enfermedades, si es necesario. Consideramos que conocer esta enfermedad y un abordaje correcto conducen a un diagnóstico apropiado. Nivel de Evidencia: IV


Achenbach's Syndrome (AS) is a pathology with low incidence and its etiology is unknown. It is characterized by the acute appearance of blue coloration in the finger without a triggering event and might be confused with an ischemic event. However, AS is a self-limited disease without sequelae. This case report is about a 75-year-old woman who presented sudden onset pain and purple coloration in the index finger of her right hand. Diagnostic tests were unhelpful and did not provide relevant information. She received symptomatic treatment, achieving complete resolution. The anamnesis and an exhaustive physical examination play a primary role in the suspicion; leaving diagnostic tests for the exclusion of other pathologies when they are required. We believe that knowing about this pathology allows a correct approach leading to an appropriate diagnosis. Level of Evidence: IV

RESUMO

Objetivo: Comunicar los resultados de una serie de adultos con consolidaciones en valgo del codo tratados con una osteotomía en cuña sustractiva monoplanar. materiales y métodos: Se incluyeron 5 pacientes. Se describe la técnica quirúrgica que consistió en un abordaje posterior paratricipital, resección en cuña sustractiva y transposición anterior del nervio cubital. El seguimiento promedio fue de 17 meses. Resultados: Se trató a 4 hombres y una mujer, con una edad promedio de 27 años. La movilidad preoperatoria promedio fue de 138-7° y la posoperatoria, de 138-6°, el puntaje de dolor en la EAV fue de 4 y 1, el MEPS de 71 y 97, y el DASH de 26 y 8, respectivamente. La evaluación radiográfica preoperatoria arrojó un valgo promedio de 30° con un valgo contralateral de 11°. La corrección radiográfica demostró un valgo de 13°. Se obtuvo una corrección promedio de 2° menos que del otro lado. Todas las osteotomías consolidaron, y la medición de la prominencia medial fue, en promedio, un 32% mayor que en el preoperatorio. Según la escala de Oppenheim, el resultado fue excelente en 4 pacientes y bueno en uno. La satisfacción personal fue, en promedio, de 8,6. Conclusiones: La osteotomía en cuña sustractiva para tratar un codo valgo es una buena opción terapéutica, con recuperación de valores angulares comparables con el lado contralateral, y alta tasa de satisfacción de los pacientes. Como es una técnica menos compleja que las osteotomías multiplanares, es nuestra elección ante una consolidación viciosa en valgo del codo del adulto. Nivel de Evidencia: IV


Objective: To report the results of a series of adult patients with a valgus malunion of the elbow treated with a supracondylar subtractive monoplanar wedge osteotomy, materials and methods: 5 patients were included. The surgical technique consisted of a posterior paratricipital approach, with resection of a subtractive wedge and the anterior transposition of the ulnar nerve. The average follow-up was 17 months.Results: 4 patients were men and 1 woman with an average age of 27 years. The preoperative range of motion was 138°-7° and the postoperative range of motion was 138-6°. Pain according to VAS was 4 and 1, MEPS was 71 and 97, and DASH was 26 and 8, respectively. The preoperative radiological evaluation showed an average valgus of 30° with a contralateral valgus of 11º. The final valgus obtained was 13°. The final correction was, on average, 2° less than the contralateral side. All osteotomies healed and the medial prominence was on average 32%, more than before surgery. According to Oppenheim scale, the results were excellent in 4 patients and good in 1. Personal satisfaction was, on average, 8.6. Conclusions: Supracondylar subtractive wedge osteotomy is a good option for the treatment of adult cubitus valgus with a recovery of angular values similar to the contralateral side and a high satisfaction rate. As it is a simpler technique, compared to the multiplanar osteotomies, it is our treatment of choice for adult cubitus valgus. Level of Evidence: IV

RESUMO

La indemnidad del aparato extensor es fundamental para un correcto funcionamiento de una prótesis de codo. Se ha considerado que la deficiencia del tríceps es una contraindicación relativa para la artroplastia, porque produce una contractura en flexión y un déficit de extensión activa. Estas limitaciones pueden afectar significativamente la mejora funcional que la artroplastia total de codo produce. Ante una seudoartrosis de olécranon, la colocación de una prótesis total de codo se presenta como un problema complejo que resolver. El objetivo de este artículo es describir la técnica quirúrgica para la colocación de una prótesis total de codo en el contexto de una seudoartrosis de olécranon, y comunicar tres casos. Nivel de Evidencia: IV


The integrity of the extensor apparatus is essential for the correct functioning of an elbow prosthesis. Triceps deficiency has been considered a relative contraindication for arthroplasty, because it produces a flexion contracture and an active extension deficit. These limitations can significantly affect the functional improvement that total elbow arthroplasty produces. Faced with an olec-ranon nonunion, the placement of a total elbow prosthesis is presented as a complex problem to be solved. The objective of this article is to describe the surgical technique for the placement of a total elbow prosthesis in the context of an olecranon nonunion, and to report three cases.

RESUMO

Introducción: El objetivo de esta serie de casos es describir los resultados y las complicaciones de pacientes con heridas gra-ves con defecto de cobertura en zonas críticas tratadas con una matriz dérmica acelular. materiales y métodos: Se realizó una revisión retrospectiva de los pacientes con déficit de cobertura en zonas críticas tratados con matriz dérmica acelular en nuestro centro. Definimos como zona crítica al déficit de cobertura que no pueda ser tratado solo con injerto de piel. Evaluamos variables preoperatorias, intraoperatorias y posoperatorias. Resultados: Los diagnósticos iniciales fueron tumor (3 pacientes), trauma agu-do (3 pacientes) y secuela de síndrome compartimental (2 pacientes). El defecto de cobertura estaba localizado en la pierna (3 casos), en la mano (2 casos), en el muslo (1 caso), en el antebrazo (1 caso) y en el pie (1 caso). La zona crítica se caracterizó por exposición tendinosa con pérdida de peritenon (5 casos), exposición ósea y pérdida de periostio (1 caso), exposición de injerto de nervio (1 caso) y exposición de osteosíntesis (1 caso). Se registraron tres complicaciones. Dos pacientes requirieron una nueva colocación de matriz y, en otro paciente, se realizó un colgajo neurocutáneo de safeno interno por fracaso de la cobertura con membrana. Conclusiones: Los sustitutos dérmicos se caracterizan por su fácil uso y versatilidad. Esta técnica otorga protección en situaciones de exposición ósea, además de proveer un plano de deslizamiento en caso de exposición tendinosa. El uso de matriz dérmica permite, además, ahorrar el empleo de colgajos. Nivel de Evidencia: IV


Introduction: The aim of this study is to report outcomes and complications in a series of patients suffering soft tissue defects in critical areas treated using an acellular dermal matrix. Materials and Method: A retrospective review of patients with soft tissue coverage deficits in critical areas treated with acellular dermal matrix in our center over a five-year period was conducted. The preoperative variables analyzed were: age, sex, comorbidities, number of previous surgeries, size and characteristics of the critical area and cause of the coverage defect. The intraoperative variables analyzed were: size of the dermal substitute used, surgical time and complications. The postoperative variables were: incorporation of the dermal substitute, time elapsed until the placement of the skin graft, and postoperative complications. Results: The initial diagnoses were tumor (3 patients), acute trauma (3 patients) and sequelae of compartment syndrome (2 patients). The soft tissue defect was located in the leg (3 cases), in the hand (2 cases), in the thigh (1 case), in the forearm (1 case) and in the foot (1 case). In 5 cases the critical zone was characterized by tendon exposure with loss of peritenon; in one case bone exposure and loss of periosteum; in one case exposure of nerve graft and in one case exposure of osteosynthesis material. Three complications were recorded. Conclusion: Dermal substitutes are characterized by their versatility. This technique can provide protection in situations of bone exposure, in addition to providing a gliding plane in case of tendon exposure. In situations of failure or impossibility of performing a biological reconstruction, dermal substitutes havea role within reconstructive options. Level of Evidence: IV

RESUMO

Objetivo: Comunicar los resultados en pacientes con un proceso infeccioso del codo, tratados en 2 etapas quirúrgicas: la primera con un espaciador de cemento con antibiótico y la segunda con una artroplastia total de codo. materiales y métodos: Se descri-ben los criterios de inclusión, el diagnóstico de infección y las 2 etapas quirúrgicas. Resultados: Se incluyeron 10 pacientes (4 hombres y 6 mujeres, edad promedio 62 años). Causas iniciales: degenerativas (2 casos) y traumáticas (8 casos). Se realizaron 4 aloprótesis y 2 colgajos de dorsal ancho. Se identificaron 2 grupos: A (defectos óseos <4 cm) y B (>4 cm). El seguimiento fue de 5 años. La flexo-extensión fue de 117°/29° en el preoperatorio y 130°/29° en el posoperatorio; los puntajes de dolor fueron 6,5 y 2,5 (EAV); 40 y 80 (MEPS); y 56 y 30 (DASH), respectivamente. La fuerza de extensión fue de M5 (4 casos), M4 (2 casos), M3 (1 caso), M1 (2 casos) y M0 (1 caso). Un paciente tuvo una necrosis del colgajo que evolucionó con infección y 9 no tenían infección al final del seguimiento. Los pacientes del grupo A tenían menos cirugías previas y mejores resultados funcionales. Conclusiones: El tratamiento de un proceso infeccioso de codo mediante un espaciador de cemento con antibiótico permite controlar la infección en un alto porcentaje de los casos. La reconstrucción protésica secundaria es demandante y se asocia a complicaciones. Cabe esperar que, cuanto más grande sea el defecto óseo y mayor la cantidad de procedimientos previos, los resultados funcionales sean peores. Nivel de Evidencia: IV


Objective: to report the results of patients with an infectious elbow process, treated in 2 surgical stages: the first with an antibiotic cement spacer (ACE) and the second with a total elbow arthroplasty. Material and methods: the inclusion criteria, the diagnosis of infection and the 2 surgical stages are described. Results: 10 patients were included (7 men and 3 women), average age: 62 years old. Initial causes: degenerative in 2 cases and traumatic in 8. 4 alloprostheses and 2 latissimus dorsi flaps were performed.Follow-up was 5 years. Flexo-extension was 117°/29° in preoperative and 130°/29° in postoperative; pain according to EVA: 6.5 and 2.5; MEPS: 40 and 80; DASH 56 and 30 respectively. The extension force was M5 (4 cases), M4 (2), M3 (1), M1 (2) and M0 (1). One patient presented a necrosis of the flap that evolved with infection. In 9 of the 10 cases the patients were free of infection at the end of the follow-up. Two groups of patients were identified: Group A (bone defects less than 4 cm) and B (more than 4 cm). Group A patients had fewer previous surgeries and better functional outcomes. Conclusion: the treatment of an infectious elbow process through the placement of antibiotic cement spacer, allows a control of the infection in a high percentage of cases. Secondary prosthetic reconstruction is demanding and associated with complications. It is to be expected that the greater the bone defect and the greater the number of previous procedures, result in the worse the functional results. Level of Evidence: IV

RESUMO

Introducción: Los métodos más utilizados para la artrodesis de la articulación interfalángica proximal y metacarpofalángica son la banda de tensión y el tornillo compresivo. El objetivo de este estudio fue comparar los resultados entre pacientes tratados con estas técnicas. Materiales y Métodos: Estudio comparativo retrospectivo de 10 años. Se incluyeron pacientes esqueléticamente maduros tratados por artrosis y artritis. Se analizaron la tasa de consolidación ósea, el tiempo hasta la consolidación, la incidencia de complicaciones y la tasa de reoperaciones. En un análisis secundario, se compararon los pacientes reumáticos y no reumáticos. Resultados: Se evaluaron 56 casos en 44 pacientes (edad promedio 53 años). Grupo 1: 35 casos tratados con banda de tensión y grupo 2: 21 tratados con tornillo compresivo. Había 32 casos reumáticos y 24 no reumáticos. El seguimiento promedio fue de 24 meses. La tasa promedio de consolidación fue del 94,2% en el grupo 1 y del 85,7% en el grupo 2. La incidencia de complicaciones fue del 11,4% en el primer grupo y 23,8% en el segundo, y la tasa de reoperaciones, del 17,1% y del 0%, respectivamente. Conclusiones: Ambos métodos permiten lograr tasas altas de consolidación, pero la incidencia de seudoartrosis fue casi tres veces superior con el tornillo compresivo que con la banda de tensión. La tasa más alta de reoperaciones en el grupo con banda de tensión fue por extracción del material. El tiempo de consolidación fue más corto en los pacientes no reumáticos, independientemente de la técnica. Nivel de Evidencia: III


Introduction: Tension band wiring (TBW) and compression screw fixation are the most common methods used for proximal interphalangeal (PIP) and metacarpophalangeal (MCP) joint arthrodesis. The aim of this study was to compare outcomes between patients treated with those methods. Materials and Methods: A 10-year retrospective comparative study. The study population included skeletally mature patients treated for osteoarthritis or arthritis. Union rates, healing times, complications, and reoperation rates were compared between TBW and compression screw fixation methods. Outcomes were also studied in terms of rheumatic and nonrheumatic patients. Results: The study sample consisted of 56 cases and 44 patients (average age, 53 years). Group 1: 35 patients treated with TBW. Group 2: 21 patients treated with compression screw fixation. There were 32 rheumatic cases and 24 nonrheumatic cases. The average follow-up was 24 months. Union rates were 94.2% (Group 1) and 85.7% (Group 2). Complication rates were 11.4% (Group 1) and 23.8% (Group 2). Reoperation rates were 17.1% (Group 1) and 0% (Group 2). Conclusions: Both methods have high union rates; however, the nonunion incidence in the compression screw group was almost three times higher than in the TBW group. The reoperation rate was higher in the TBW group, mostly due to hardware removal. Healing time was shorter in non-rheumatic patients regardless of the method. Level of Evidence; III

RESUMO

Objetivo: Evaluar los resultados y las complicaciones de una serie de pacientes con consolidación viciosa de falange. Materiales y Métodos: Se realizó un estudio retrospectivo que incluyó a pacientes con consolidación viciosa de falange tratados mediante osteotomía en el sitio de la deformidad, estabilizados con osteosíntesis rígida. Se registró la movilidad de los dedos. La valoración subjetiva consistió en el puntaje DASH y una escala analógica visual para el dolor en reposo, en actividad y la función. Resultados: Doce pacientes (13 falanges) cumplieron los criterios de inclusión. El tiempo promedio entre la lesión inicial y la osteotomía fue 14 meses y el seguimiento promedio, 34 meses. La movilidad final promedio en flexo-extensión fue 89° metacarpofalángica, 74° interfalángica proximal, 54° interfalángica distal y la distancia pulpejo-palma, 3 mm. El puntaje promedio de la escala analógica visual en reposo fue 0; en actividad, 1 y la función promedio fue de 7 puntos; el puntaje DASH promedio fue 6. No hubo casos de seudoartrosis. Cinco pacientes requirieron el retiro de la placa. Los pacientes con osteotomía articular no presentaron signos de artrosis. Conclusiones: La osteotomía de falange en el sitio de la deformidad es un procedimiento eficaz con un buen resultado objetivo y subjetivo a corto plazo. La utilización de placas y tornillos conlleva una tasa más alta de complicaciones; por lo tanto, los pacientes deben ser advertidos sobre la posibilidad de una segunda intervención quirúrgica. Nivel de Evidencia: IV


Objective: To present the results and complications of a series of phalangeal malunion patients. Materials and Methods: A retrospective study was conducted on phalangeal malunion patients treated with an osteotomy at the deformity site and stabilized with rigid internal fixation. Postoperative mobility of the digit was recorded. The subjective assessment used the Disabilities of the Arm, Shoulder and Hand (DASH) score and a Visual Analogue Scale (VAS) to rate their function and pain at rest and during activity. Results: Twelve patients (13 phalanges) met the inclusion criteria. The average time between fracture and osteotomy was 14 months and the mean follow-up was 34 months. Final mobility in flexo-extension was: 89 degrees for metacarpophalangeal joint, 74 degrees proximal interphalangeal joint, 54 degrees distal interphalangeal joint. The average VAS pain score was 0 at rest and 1 during activity, and the average function was 7 points. The average DASH score was 6. There were no cases of nonunion. Five patients required plate removal. No patients with articular osteotomy presented signs of Osteoarthritis. Conclusions: Phalangeal osteotomy at the deformity site is an effective procedure with good objective and subjective short-term outcomes. Patients should be warned about the possibility of a second procedure in cases of plate fixation due to a higher complication rate associated with plate and screw fixations. Level of Evidence: IV

RESUMO

La osteonecrosis del semilunar o enfermedad de Kienböck es un cuadro progresivo y debilitante que puede llevar al dolor crónico y la pérdida de la función. Pese a que se conoce hace más de 100 años, la etiología todavía es incierta, si bien se la ha relaciona-do con factores mecánicos, vasculares y traumáticos. Su evolución natural está pobremente definida y los hallazgos radiográficos no siempre se correlacionan con los hallazgos clínicos. Se han logrado avances para identificar y entender la progresión del pro-ceso avascular y sus efectos nocivos sobre la mecánica de la muñeca. El tratamiento inicial es no quirúrgico. El perfeccionamiento de la técnica quirúrgica utilizando injertos óseos vascularizados de radio distal puede mejorar los resultados en los pacientes que cursan etapas tempranas de la enfermedad, aunque resta mucho trabajo para determinar si este tratamiento quirúrgico re-presenta una mejor opción que los tratamientos tradicionales. Reportes recientes de resultados a largo plazo de la osteotomía de acortamiento del radio para estadios tempranos de la enfermedad y la resección de la primera fila del carpo para estadios avan-zados revelan que estos procedimientos son una opción válida para el tratamiento a largo plazo de este cuadro de difícil manejo.


Osteonecrosis of the lunate or Kienböck's disease is a progressive, debilitating condition that can lead to chronic pain and function loss. Despite it was identified almost 100 years ago, the etiology remains unknown, although mechanical, vascular, and traumatic factors have been associated. The natural history of Kienböck's disease is poorly defined, and the radiographic findings do not always correlate with the clinical findings. There has been some progress in identifying and understanding the progression of the avascular process and its deleterious effects on wrist mechanics. Initial treatment is conservative. Improvement in surgical tech-niques with vascularized bone grafts from the distal radius may lead to an outcome improvement for patients in the early stages of disease. However, more research is still needed to determine whether this surgical treatment represents an improvement over conventional treatment alternatives. Recent reports of long-term outcomes for radial shortening osteotomy in osteonecrosis early stage patients and for proximal row carpectomy (PRC) in advanced Kienböck's disease patients reveal that these procedures provide reliable options for the long-term management of this challenging condition.

RESUMO

La compresión mecánica de un nervio periférico en dos sitios diferentes a lo largo de su trayecto se define como síndrome de doble compresión. Esta enfermedad se basa en la teoría de la mayor susceptibilidad que tendría un nervio a nivel distal cuando este también se encuentra comprimido, en forma asintomática, a nivel proximal, debido a una alteración en el flujo axonal. Si bien la descompresión del túnel carpiano es una cirugía con resultados previsibles, hay pacientes operados por síndrome del túnel carpiano que no mejoran después de una cirugía, como cabría esperar. Si se excluye de este análisis a las comorbilidades, como diabetes, casos avanzados con atrofia muscular o descompresiones insuficientes, muchos de estos fracasos terapéuticos podrían estar fundamentados por el escaso diagnóstico de un segundo sitio de compresión concomitante. No obstante, existe gran controversia alrededor del síndrome de doble compresión que involucra no solo a su existencia, sino también a su incidencia y fisiopatología. El objetivo de esta publicación es presentar una revisión bibliográfica crítica del síndrome de doble compresión centrada en el compromiso del nervio mediano tanto en la muñeca como en el codo.


Double crush syndrome is the mechanical compression of a peripheral nerve at two different sites and is based on the hypothesis that a nerve that has been compressed at a distal site is especially susceptible to also be compressed, asymptomatically, at a more proximal site. While carpal tunnel release is a surgical procedure with predictable results, some patients do not improve as expected after surgery. If comorbidities such as diabetes, advanced cases presenting with muscle atrophy or incomplete decompressions are excluded from the analysis, many of these treatment failures could be explained by a second concomitant compression site, which is often underdiagnosed. The very existence of double crush syndrome is highly questioned, but also its incidence and pathophysiology. The objective of our paper is to perform a critical review of the literature available on double crush syndrome involving mainly the median nerve in the wrist and the elbow.

RESUMO

Objective To report the consolidation rate and the results of a series of 22 patients with metaphyseal core decompression of the distal radius and an antegrade compression screw. Methods We present a prospective series of patients with scaphoid proximal pole nonunion in whom the presence of intraoperative bleeding was confirmed in both fragments. Patients with displacement, degenerative changes, fragmentation of the proximal pole, cavitation of the focus, loss of height, and necrosis, as well as those with carpal instability, were excluded. The patients were evaluated with X-rays and computed tomography to evaluate their consolidation; their mobility and fist strength were recorded and an analog visual scale (VAS) of pain at rest, pain in activity, subjective functional status, and DASH questionnaire were completed. Results Of the 23 patients, 21 accomplished union. The average follow-up was 19 months and the average final range of motion was flexion 86%, extension 85%, radial deviation 79%, ulnar deviation 84%, and grip strength 84%. The average VAS for pain at rest was 1 point, the average VAS for activity pain was 2 points, the average VAS for function was 9 points, and the average DASH score was 8. Conclusions Using this simple and reliable technique, we obtained 91% union and very good functional results. Metaphyseal core decompression of the distal radius associated with an antegrade scaphoid screw is a reasonable and effective option for the treatment of proximal pole scaphoid nonunions without avascular necrosis in carefully selected patients. Level of Evidence This is Level IV study.

RESUMO

Objetivo: Comunicar la eficacia del clavo endomedular recubierto con antibiótico (CERA) para erradicar la infección en la seudoartrosis infectada de húmero (SIH). Materiales y Métodos: Once pacientes (edad promedio 48 años). El tiempo entre la fractura y la cirugía fue 25 meses. El CERA se impregnó con vancomicina en 9 pacientes. El seguimiento promedio fue de 54 meses. Resultados: Se aisló S. aureus resistente a meticilina (SARM) en 5 pacientes. Todos recibieron antibióticos sistémicos por 7 semanas. El antibiótico más utilizado fue vancomicina. La mediana entre el primer tiempo quirúrgico y la reconstrucción fue 56 días (RIC 47-98). Luego del desbridamiento quirúrgico del primer tiempo, se midió el defecto óseo remanente y se lo dividió con variables dicotómicas: grupo con defectos <2 cm (7 pacientes) y grupo con defectos ≥2 cm (4 pacientes). No se observaron diferencias significativas entre la mediana de días entre el primero y segundo tiempo quirúrgico comparando el desarrollo de SARM con el de otros gérmenes (48 días [RIC 45-75] vs. 73,5 días [RIC 56-149], p = 0,2002 Mann-Whitney), ni en la proporción del tamaño del defecto óseo según el desarrollo de SARM o de otro germen (60% vs. 17%, p = 0,242 Fisher). Todos los cultivos fueron negativos y se logró la consolidación del foco fracturario, sin recurrencia de la infección. Conclusiones: El CERA es una buena opción terapéutica en el primer tiempo quirúrgico para un paciente con SIH. Se pudo controlar la infección, lo que permitió la reconstrucción secundaria de la seudoartrosis. Nivel de Evidencia: IV


Objective: To evaluate the efficiency of the antibiotic cement-coated rods (ACCR) to erradicate infections in infected nonunion of the humerus (INH). Methods: We included 11 patients with INH with a mean age of 48 years. The time from fracture to surgery was 25 months. The ACCR was impregnated with vancomycin in 9 of 11 cases. Follow-up was 54 months. Results: Methicillinresistant Staphylococcus aureus (MRSA) was isolated in 5 cases. All patients received systemic antibiotic treatment for 7 weeks. Vancomycin was the most commonly used antibiotic. Time from ACCR placement to reconstructive surgery averaged 56 days [confidence interval range (CIR) 47-98]. After debridement and implant removal, the residual deformity of the nonunion was measured with dichotomous variables and classified into two groups: group 1, <2 cm (7 patients) and group 2, ≥2 cm (4 patients). No significant differences were observed between the number of days from placement of the ACCR to the development of the MRSA infection, compared to other pathogens [48 days (CIR 45-75) vs. 73 days (CIR 56-149) p=0.2002, Mann-Whitney U test], nor were differences observed in the size of the defect in those who developed MRSA or by any other pathogen (p=0.242, Fisher exact test). Reconstruction was performed with different techniques. Laboratory parameters were normal and cultures were negative. Fractures achieved consolidation without recurrence of the infection. Conclusions: ACCRs are an adequate treatment option for patients with an INH. The infection was controlled in all cases, which allowed for the secondary reconstruction of the nonunion. Level of Evidence: IV
