RESUMEN
Abstract Small osteolabral avulsions of the hip can be easily missed, and postreduction stress testing and computed tomography (CT) scans of the hip should be performed to look for these injuries. The usual modality of treatment of these unstable osteolabral avulsions is suture anchors, Herbert screws or spring plates. But when the bony avulsion is small, the use of these implants becomes a tedious job. We present a novel technique to fix small osteochondral avulsion fractures not amenable to fixation using screws or spring plates. We performed a retrospective analysis of 57 cases of patients who underwent open reduction and internal fixation for posterior fracture dislocation of the acetabulum, and we identified 6 cases of small posterior labral osteochondral fragments leading to instability. These injuries were fixed using a novel method. The mean Harris Hip Score at the final follow-up was of 92.5. Fixation of osteochondral avulsions associated with posterior hip fracture dislocation can be a difficult task if the bony fragment is small. Our technique is a simple, cost-effective and reliable way of fixing such avulsions with satisfactory outcomes.
Resumo Pequenas avulsões osteolabrais do quadril podem passar despercebidas, e testes de estresse pós-redução e tomografia computadorizada do quadril devem ser realizados para sua detecção. O tratamento dessas avulsões osteolabrais instáveis geralmente é feito com âncoras de sutura, parafusos de Herbert ou placas-molas. Em avulsões ósseas pequenas, porém, o uso desses implantes é um trabalho tedioso. Apresentamos uma nova técnica de fixação de pequenas fraturas com avulsões osteocondrais não passíveis de fixação com parafusos ou placas-molas. Realizamos uma análise retrospectiva de 57 casos de pacientes submetidos à redução aberta e fixação interna de fratura-luxação posterior do acetábulo, e identificamos 6 casos em que um pequeno fragmento osteocondral labral posterior causava instabilidade. Essas lesões foram corrigidas com um novo método. A pontuação média no Harris Hip Score no último acompanhamento foi de 92,5. A fixação de avulsões osteocondrais associadas a fratura-luxação posterior do quadril pode ser difícil se o fragmento ósseo for pequeno. Nossa técnica é uma maneira simples, econômica e confiável de corrigir tais avulsões com resultados satisfatórios.

BACKGROUND: Some children and adolescents can develop persistent pain and instability following inversion injuries of the ankle. In these cases, imaging exams could reveal small bone fragments distal to the lateral malleolus. For these patients, regular conservative treatment may not be successful, requiring additional management, which can include surgical treatment. This study aimed to present the short-to-midterm functional and clinical outcomes of a series of 12 pediatric and adolescent patients who underwent ligament repair surgery due to chronic instability associated with the presence of osseous components in the lateral ligaments. METHODS: A review of 12 patients treated with surgical ligament reconstruction of the ankle was evaluated. Clinical and functional evaluations were based on comparing the Visual Analogue Scale (VAS), AOFAS ankle-hindfoot score, and residual symptoms before and after the surgical intervention. RESULTS: Before the reconstructive approach, the mean VAS was 2.41 and the mean AOFAS score was 74.16. After the procedure, the standard VAS declined to zero, and the AOFAS score was 100 in all patients. The mean follow-up was 6.33 months. CONCLUSION: The surgical approach in children and adolescents with symptomatic ankle instability due to the presence of osseous fragments after an initial inversion trauma provided adequate clinical and functional results at short-to-midterm follow-up. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Introducción: Las epifisiólisis de la tuberosidad anterior de la tibia en adolescentes representan el 1% de las lesiones fisarias y el 3% de las fracturas de la tibia proximal, y pueden comprometer la fisis; por lo tanto, ameritan un diagnóstico y un tratamiento correctos para evitar complicaciones. El objetivo de este artículo es comunicar un caso clínico, compararlo con casos similares publicados, analizar las diferencias y, sobre la base de la experiencia, llegar a una conclusión para su resolución. Presentamos a un varón de 13 años que consultó tras sufrir un traumatismo directo en la rodilla derecha, durante la carrera en la práctica deportiva, un mes atrás. La radiografía mostró epifisiólisis por avulsión de la tuberosidad anterior de la tibia (Ogden IIIA, Jones III), por lo que fue sometido a reducción abierta y fijación. Como la recuperación y el retorno a la actividad habitual fueron rápidos, se tomaron un par radiográfico para el diagnóstico y una tomografía para la planificación quirúrgica. Conclusión: Si bien no hay un consenso sobre el diagnóstico y el tratamiento por la baja cantidad de casos publicados, es conveniente sospechar este cuadro en pacientes jóvenes que sufren un traumatismo en la rodilla que limita la extensión. Nivel de Evidencia: IV
Epiphysiolysis of the anterior tibial tubercle in adolescents accounts for 1% of physeal injuries and 3% of proximal tibial fractures, and it may involve the physis, necessitating diagnosis and treatment to prevent complications. Objective: To present a case, compare it existing literature, analyze differences, and propose resolutions based on our experience. A 13-year-old male consulted after suffering direct trauma to his right knee while running in sports practice one month earlier. Radiography revealed epiphysiolysis due to avulsion of the anterior tibial tubercle (Odgen IIIA and Jones III), prompting open reduction and internal fixation with two partially-threaded cannulated screws and washers. After six weeks of cast immobilization, he began rehabilitation. Given his swift recovery, AP and lateral radiographs were obtained for diagnosis and a CT scan for surgery planning, leading to a second surgery involving open reduction and internal fixation with two cannulated screws surrounding the physis, although the patellar tendon was explored first to mitigate the risk of invagination within the fracture line. Conclusion: Despite the scarcity of reported cases, a rising trend due to increased youth sports participation underscores the importance of considering this injury in young patients presenting with knee trauma and restricted extension.

Abstract The present study reports a rare case of avulsion fracture of the tibial tuberosity in an adolescent. A 14-year-old male patient sprained his left knee during a soccer match. At the first emergency-room visit, he presented pain in his left knee, 2 +/4+ edema, and inability to walk and flex the affected knee, but no neurovascular changes or signs of compartment syndrome. Radiographs revealed a physeal fracture at the left proximal tibia, classified by Ogden, Tross and Murphy, and modified by Ryu and Debenham, as type IV, and complemented by Aerts et al. as type IV-B. Immobilization was performed with a plaster cast from the inguinal to malleolar regions, followed by analgesia. The patient was operated on the next day, when open reduction and internal fixation using 4.5-mm cannulated screws were performed. The patient was discharged one day after surgery, with plaster cast immobilization and load restraint for four weeks, and bone consolidation was radiologically confirmed three months after the procedure. The patient evolved with a range of motion similar to that of the contralateral limb, no length discrepancy in the lower limbs, and no complaints after one year of follow-up.
Resumo O presente estudo tem como objetivo relatar um caso raro de fratura por avulsão da tuberosidade da tíbia em adolescente. Um paciente de 14 anos, do sexo masculino, sofreu entorse de joelho esquerdo durante partida de futebol. No primeiro atendimento em pronto-socorro, ele apresentava dor no joelho esquerdo, edema 2 +/4 + , incapacidade de deambulação e de flexo-extensão do joelho acometido, sem alterações neurovasculares ou sinais de síndrome compartimental. Nas radiografias, identificou-se fratura fisária na tíbia proximal esquerda, classificada por Ogden, Tross e Murphy, com modificação por Ryu e Debenham, como tipo IV, e complementada por Aerts et al. como tipo IV-B. Foi realizada imobilização com tala gessada inguino-maleolar e analgesia, e o paciente submetido a cirurgia no dia seguinte, com redução aberta e fixação interna utilizando parafusos canulados 4,5 mm. O paciente recebeu alta no dia seguinte à cirurgia, sendo mantida a imobilização com tala gessada e a restrição de carga por quatro semanas, e apresentou consolidação óssea confirmada por radiografia com três meses do pós-operatório. O paciente evoluiu sem discrepância de comprimento dos membros inferiores, arco de movimento igual ao do membro contralateral, e sem queixas no seguimento de um ano.

BACKGROUND: Proximal tibial physeal development and closure is thought to relate to tibial tubercle avulsion fracture (TTAF) patterns. Prior work has yet to formally evaluate the relationship between skeletal maturity and fracture pattern.⯠Using 2 knee radiograph-derived skeletal maturity assessments [growth remaining percentage (GRP) and epiphyseal union stage], we examined their association with TTAF injury patterns using the Ogden and Pandya fracture classifications. We hypothesized that different TTAF injuries would occur during unique periods of skeletal development. METHODS: Pediatric patients sustaining TTAFs treated at a single institution (2008-2022) were identified using diagnostic and procedural coding. Demographics and injury characteristics were collected. Radiographs were reviewed to assign epiphyseal union stage, Ogden and Pandya classifications and for measurements to calculate GRP. Univariate analyses examined the relationship between injury subgroups, patient demographics, and skeletal maturity assessments. RESULTS: Inclusion criteria identified 173 patients with a mean age of 14.76 (SD: 1.78) and 2.95% (SD: 4.46%) of growth remaining. The majority of injuries were classified Ogden III/Pandya C. Most (54.9%) were the result of the axial loading mechanism. Ogden groups showed no significant differences across all patient characteristics studied including age and GRP. With the exception of Pandya A fractures, we did not identify a direct relationship between GRP, age, and Pandya groups. Epiphyseal union stage differed for Pandya A and D groups. CONCLUSIONS: A predictable pattern in TTAF characteristics across skeletal (GRP), epiphyseal union, or chronologic age was not identified in this study. Distal apophyseal avulsions (Ogden I/II and Pandya A/D) occurred across a broad chronologic and skeletal age range. No differences were identified in epiphyseal or posterior extension (Ogden III/IV and Pandya B/C) injuries. Although differences in age and GRP were identified among Pandya As, this is thought to be due to the degree of skeletal immaturity that is a prerequisite for differentiation from Pandya Ds. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

Introducción: La avulsión de la espina tibial posterior en el adulto representa una forma infrecuente de compromiso del ligamento cruzado posterior (LCP), más común de ver en la población pediátrica. La posibilidad de consolidación de esta lesión, con el tratamiento adecuado en forma temprana, depende de un diagnóstico precoz. Caso: reportamos el caso de una paciente de veintisiete años con una lesión multiligamentaria de rodilla con inestabilidad medial y posterior, por trauma de alta energía tras sufrir un accidente de tránsito en moto. Fue tratada mediante una fijación abierta con técnica de "pull-out". Discusión: en países asiáticos es una lesión frecuente por la alta prevalencia de accidentes en moto, pero menos común en nuestro medio. Si bien el manejo quirúrgico temprano muestra mejores resultados, no existe consenso actual en cuanto a la técnica. Dos tipos de resolución (abierta y artroscópica) muestran resultados similares a largo plazo, con un mayor porcentaje de artrofibrosis en el último grupo. Conclusión: al existir controversia sobre su manejo quirúrgico, creemos que la combinación de las ventajas de ambas técnicas (abierta y artroscópica) constituye una opción reproducible, de bajo costo y con bajo índice de complicaciones.
Introduction: Avulsion of the posterior tibial spine in adults represents an infrequent form of compromise of the posterior cruciate ligament (PCL), more common to see in the pediatric population. The possibility of consolidation of this lesion, with adequate treatment early, depends on an early diagnosis.Case: we report the case of a 27-year-old patient with a multiligamentary knee injury with medial and posterior instability, due to high-energy trauma after suffering a motorcycle traffic accident. Which was treated with an open fixation with a "pull-out" technique. Discussion: in Asian countries it is a frequent injury due to the high prevalence of motorcycle accidents, being less common in our continent. Although early surgical management shows better results, there is no current consensus regarding the optimal technique. Both types of resolution (open and arthroscopic) show similar long-term results, with a higher risk of arthrofibrosis in the last group. Conclusion: as there is controversy over its surgical management, we believe that the combination of the advantages of both techniques (open and arthroscopic) constitutes a reproducible, low-cost option with a low rate of complications.

BACKGROUND: Tibial tubercle avulsion fractures (TTAF) often require surgical reduction and stabilization. Traditional teachings recommend postoperative knee immobilization for 4 to 6 weeks; however, the necessity of these restrictions is unclear and the actual practice varies. This study's purpose was to: (1) retrospectively review operatively managed TTAFs at a single center to examine the spectrum of postoperative rehabilitation guidelines, and (2) compare the outcomes of patients based on the timing of initiation of postoperative knee range of motion (ROM). METHODS: Operatively managed TTAFs treated at a single center from 2011-2020 were identified. Patients with polytrauma, associated lower extremity compartment syndrome, or treatment other than screw fixation were excluded. Patient demographics, mechanism of injury, Ogden Classification, associated injuries, operative technique, postoperative ROM progression, and time to release to unrestricted activities were collected. Patients were grouped based on the initiation of postoperative ROM as Early (<4 wk, EROM) or Late (≥4 wk, LROM). Bivariate analysis was used to compare characteristics between these 2 groups. RESULTS: Study criteria identified 134 patients, 93.3% (n=125) of whom were male. The mean age of the cohort was 14.77 years [95% confidence interval (CI: 14.5 to 15.0]. Forty-nine patients were designated EROM; 85 patients were categorized as LROM. The groups did not differ significantly with regards to age, race, injury characteristics, or surgical technique. Both groups progressed similarly with regards to postoperative range of motion. Ultimate activity clearance was achieved at ~20 weeks postoperatively without differences between groups ( P >0.05). Four instances of postoperative complication were identified, all of which occurred in the LROM group. CONCLUSION: A broad range of postoperative immobilization protocols exists following the screw fixation of TTAFs. Across otherwise similar cohorts of patients undergoing operative treatment, initiation of knee range of motion before 4 weeks was without complication and provided equivalent outcomes to traditional immobilization practices. Given the clear benefits to patients and caregivers provided by the permission of early knee motion and the avoidance of casting, providers should consider more progressive postoperative rehab protocols following operatively treated TTAFs. LEVEL OF EVIDENCE: Level III, Retrospective Cohort.

Las fracturas del calcáneo representan el 2-3,1% de las fracturas en general y las avulsiones del tendón de Aquiles son las menos frecuentes de este grupo. Fueron descritas por Bohler como "fracturas en pico de pato". Los casos publicados son muy escasos, Sang-Myung y cols. publicaron la revisión más grande con 764 casos de fracturas de calcáneo, 20 de ellos con avulsión de la tuberosidad del calcáneo. Los mecanismos de acción más frecuentes son tropiezo, caída o golpe directo. Se presenta a un paciente de 48 años que concurre al Servicio de Urgencias de un hospital de segundo nivel, tras caerse de un árbol y quedar suspendido sobre la pierna derecha. Ingresó para estudio con evidencia radiográfica de fractura por avulsión del calcáneo y fue sometido a una osteosíntesis, con una excelente evolución clínica. Consideramos importante comunicar este caso, dada la escasa frecuencia de este tipo de fracturas. Nivel de Evidencia: IV
Calcaneal fractures account for 2-3.1% of all fractures; among these the least common are avulsions of the Achilles tendon, described by Dr Bohler as "Beak fractures". Descriptions in the literature are very scarce, the largest report being that of Sang-Myung et al in 2012, where a summary of 764 cases of calcaneal fractures contained 20 avulsion fractures. The most common mechanisms of trauma are tripping, falling, or a direct knock. This report presents the clinical case of a 48 year-old patient, who attended the Emergency Service of a second-level hospital after falling from a tree which resulted in being suspended by the lower right limb. Radiographs revealed signs of a calcaneal avulsion fracture, which was surgically managed via osteosynthesis with excellent clinical outcomes in follow-up. Given the infrequency of this type of fracture, we considered it important to present this article. Level of Evidence; IV

One dog, Golden Retriever, 5 months old, was seen complaining of lameness and pain in the left pelvic limb. Avulsion of the tibial crest was diagnosed by radiographic means, which was corrected with a tension band. The absence of postoperative radiographic monitoring and the non-removal of the apparatus led to the early closure of the cranial tibial physis with continuous flow growth, resulting in pain, functional loss of the limb after one year and at a 13.2º tibial plateau angle negative. The biomechanical alteration of the limb was corrected using the inverted TPLO technique, converting the angle of the tibial plateau to 5.3 positive, without a rockback evidenced in 30, 60, 90 days up to four months after the operation. The objective of this case report is to describe the surgical correction with the inverted TPLO technique in a case of angle of the negative tibial plateau secondary to not removing the tension band applied in avulsion of the growing tibial crest. After 120 days, the dog was presented fully recovery and weight-bearing without any complication.
Um cão, Golden Retriever, de 5 meses de idade, foi atendido com queixa de claudicação e dor em membro pélvico esquerdo. Diagnosticou-se por meio radiográfico a avulsão da crista da tíbia, a qual foi corrigida com banda de tensão. A ausência de acompanhamento radiográfico pós-operatório e a não retirada do aparato levou ao fechamento precoce da fise tibial cranial com crescimento contínuo da caudal, resultando em dor, perda funcional do membro após um ano e em um ângulo de platô tibial de 13,2º negativos. A alteração biomecânica do membro foi corrigida por meio da técnica de TPLO invertida, convertendo o ângulo do platô tibial em 5,3º positivos, sem rockback evidenciado em 30, 60, 90 dias até quatro meses de pós-operatório. O objetivo desse relato de caso é descrever a correção cirúrgica com a técnica de TPLO invertida em um caso de ângulo do platô tibial negativo secundário a não retirada de banda de tensão aplicada em avulsão da crista da tíbia em crescimento. Após 120 dias, o paciente apresentou recuperação total com adequado suporte do peso no membro, sem qualquer complicação.

This research aims to present a novel arthroscopic fixation technique that uses a double-row suture anchor for tibial spine avulsion and to evaluate its short-term clinical outcomes. The surgical technique is described and a retrospective case series is presented. Patients who presented with tibial spine avulsion type III and IV fractures according to the Meyers and McKeever classification and received the same surgical treatment from 2013 to 2018 in two specialised hospitals in Medellín City were included. All interventions were performed by an experienced surgeon. To determine outcomes during clinical follow-up, the Lysholm score and objective and subjective International Knee Documentation Committee scores were obtained before and at least 12 months after surgery. A total of 24 patients were followed, with a mean age of 31 years; 12 patients were female. The median time between trauma and surgical fixation was 12 days (IQR=7-23), with a median follow-up period of 13.5 months (IQR=9.5-31.5). When comparing patients' state initially and during the postoperative period, statistically significant differences were found in all the scores analysed (p<0.05). Likewise, there were no complications and no reinterventions performed during follow-up, and all patients were satisfied with the outcomes of the procedure. Fixation of tibial spine avulsion fractures using the double-row suture anchor technique results in improvement in patients' function, pain and activity level. The main conclusion is that the procedure is an anatomical technique that requires minimal access and leads to satisfactory clinical evolution of patients. Level of evidence: Level V, case series.

OBJETIVO: Realizar la evaluación clínica, imagenológica y funcional de pacientes con fracturas avulsivas tibiales del ligamento cruzado posterior (FTALCPs) fijadas con tornillos canulados con técnica abierta. MÉTODOS: Los pacientes con FTALCP operados entre 2010 y 2017 fueron revisados retrospectivamente. Criterios de inclusión: fracturas agudas, desplazadas, test de cajón posterior grado III, lesiones combinadas de rodilla, seguimiento > 12 meses. Se excluyeron pacientes > 65 años, con FTALCPs bilaterales, lesiones del ligamento cruzado posterior (LCP) intrasustancia, test de cajón posterior grados I-II, fracturas expuestas, lesiones neurovasculares, y seguimientos < 12 meses. Objetivo primario: medir la estabilidad clínica mediante test de cajón posterior y radiografía de estrés arrodillada comparativa. Objetivos secundarios: nvaluar la consolidación en radiografías, complicaciones y funcionalidad con las escalas de Lysholm y Tegner. Resultados Se incluyeron 20 pacientes, con edad media de 41 años (rango: 32 a 61 años). El seguimiento promedio fue de 33,9 meses (rango: 12 a 82 meses). La estabilidad clínica mejoró en 93% (cajón posterior postoperatorio grados 0 y I) de los pacientes. La radiografía de estrés arrodillada mostró una diferencia promedio de 2,6 mm (rango: 0,1 mm a 6,8 mm) de traslación posterior al comparar con el lado sano. Todas las fracturas consolidaron. Siete pacientes presentaron complicaciones. El puntaje promedio de la escala de Lysholm al final del seguimiento fue de 85,17. El promedio preoperatorio del puntaje en la escala de Tegner no varió significativamente en comparación con el postoperatorio. CONCLUSIONES: La fijación de fracturas avulsivas tibiales del LCP con tornillos canulados con técnica abierta es efectiva en restaurar la estabilidad posterior y lograr la consolidación ósea. La funcionalidad clínica a mediano plazo es buena, a pesar del alto número de complicaciones y lesiones concomitantes. NIVEL DE EVIDENCIA: tipo IV.
OBJECTIVE: To report mid-term clinical, radiographic, and functional outcomes following open reduction and fixation of posterior cruciate ligament tibial avulsion fractures (PCLTAFs) with cannulated screws. METHODS: This is a retrospective analysis of patients with PCLTAF operated on from August 2010 to April 2017. Patients with acute fractures, with more than 2 mm of displacement and grade III on the posterior drawer test, combined or not to knee injuries, were included. Patients older than 65 years of age, with bilateral avulsion fractures, intrasubstance posterior cruciate ligament (PCL) lesions, stable grade-I to -II on the posterior drawer test, concomitant neurovascular injuries, mid-substance tears, open fractures, and less than 12 months of follow-up were excluded. Primary outcomes: the clinical stability was assessed using the posterior drawer test and a single comparative knee stress radiograph. Secondary outcomes: radiographic consolidation, complications, Lysholm score, and Tegner activity score. RESULTS: In total, 20 patients with a mean age of 41 years (range: 32 to 61 years) were included. The mean follow-up was of 33.9 months (range: 12 to 82 months). Clinical stability (grade 0 or I on the posterior drawer test) was observed in 93% of the patients. The mean difference in contralateral posterior displacement was of 2.6 mm (range: 0.1 mm to 6.8 mm) on a single comparative knee stress radiograph. All fractures presented radiological consolidation. Seven patients developed complications. The mean Lysholm score at the last follow-up visit was of 85.17. The postoperative Tegner activity scores did no vary significantly compared to the preinjury scores. CONCLUSIONS: Cannulated screw fixation of a displaced PCLTAF through a posterior approach restores clinical and radiographic stability and has excellent union rates. The mid-term functional outcomes are good despite the high rates of combined knee lesions and postoperative complications. LEVEL OF EVIDENCE: IV.

Abstract Objective To verify the applicability and agreement of the Ottawa ankle rules applied by medical students and orthopedic residents in a tertiary trauma service thus validating the Ottawa protocol for use on Brazilian soil. Prospective This was a prospective study, conducted in a tertiary hospital, including all patients with acute torsial trauma of the tibiotarsal joint. The patients underwent ankle and/or foot radiographs, and the questionnaire with the Ottawa ankle rules was applied by academics and, subsequently, by residents. The radiographs were evaluated by on-call orthopedists and specialist in foot and ankle, and the expert opinion was considered the gold standard for analysis. Results Two hundred and sixty-three patients were evaluated, and, after application of the established inclusion criteria, 226 cases remained for evaluation. The sensitivity to detect lesions and negative predictive value (NPV) was 100%. The most sensitive test with higher NPV for both academics and residents was palpation of the lateral malleolus. The study presented potential for a reduction of 30% in the total number of tests requested. Conclusion The data showed applicability and agreement between academics and residents, which allows for the validation of the Ottawa protocol in emergency care in Brazil.

BACKGROUND: Patellar sleeve avulsion (PSA) fractures are rare injuries that occur in in skeletally immature patients. Initial diagnosis is key to a successful outcome, as these injuries are easily overlooked on plain radiographs with poor results well documented from delayed management. High index of suspicion from the mechanism of injury, thorough clinical examination and Magnetic Resonance Imaging (MRI) help to avoid misdiagnosis. CASE PRESENTATION: The case of a 12-year-old male athlete with an acute PSA after a conservative treatment of a SLJ syndrome is described. The patient was referred to our clinic due to severe pain and loss of function after performing a high jump. Plain radiographs (X-ray) and MRI confirmed an inferior pole PSA which was fixed with double trans osseous ultra-high strength tapes. At the 3-month follow- up visit the patient was able to ambulate brace free. At 2-years follow up the patient was able to play soccer and ice hockey. To our knowledge, there are no case reports of inferior pole PSA with prior SLJ syndrome described in literature. CONCLUSIONS: Early clinical suspicion and distinguishing this PSA from other enchondral ossification disorders around the knee is critical to avoid misdiagnosis. Whether SLJ syndrome increases the risk of sustaining a PSA is still not clear. Trans osseous fixation with suture tapes leads to good functional results in a young athlete with inferior pole PSA.

BACKGROUND: Zone 1 fractures of the proximal fifth metatarsal are usually treated nonsurgically using some type of immobilization. The aim of this study was to compare clinical and functional outcomes, time to return to prior activity levels, and rate of bone healing when using a hard-soled shoe (HSS) vs a controlled ankle motion (CAM)-walker boot (CWB). METHODS: Seventy-two consecutive patients with zone 1 fractures of the fifth metatarsal base were treated conservatively with either an HSS or CWB by 2 different providers. We included 57 women and 15 men, average age of 41.3 (range, 16-88) years. Radiographic findings, visual analog scale (VAS) for pain, and American Orthopaedic Ankle & Foot Society (AOFAS) midfoot score were assessed. Patients were followed at 4, 8, 10, 12, and 24 weeks or until asymptomatic and able to return to prior level of activities. Statistical analysis was performed using Mann-Whitney U, Fisher exact, and chi-square tests. P values <.05 were considered significant. RESULTS: Age and gender distributions were similar in both groups (P = .23 and P = .57). Patients had similar VAS and AOFAS scores after 8 (P = .34 and P = .83) and 12 (P = .87 and P = .79) weeks. Average time for bone healing was significantly faster using the CWB (7.2 weeks) when compared to the HSS (8.6 weeks) (P < .001). The average time to return to prior level of activities was similar in both groups (8.3 weeks for CWB and 9.7 weeks for HSS) (P = .11). Fracture displacement was equal in both groups, with a mean of 1.9 mm of displacement in patients using the HSS, and a mean of 1.6 mm in those using the CWB (P = .26). CONCLUSION: Zone 1 fractures of the proximal fifth metatarsal can be treated conservatively with either a hard-soled shoe or a CAM-walker boot. Even though patients treated in the CAM-walker boot demonstrated earlier signs of complete healing, similar clinical and functional results were achieved with both treatments. LEVEL OF EVIDENCE: Level III, retrospective comparative series.

PURPOSE OF REVIEW: To summarize and discuss the fundamentals of pediatric tibial tubercle avulsion fractures (TTAFs) including preferred imaging modalities, systems for fracture classification, frequently associated injuries, treatment options, outcomes, and common complications. RECENT FINDINGS: Although TTAFs amount to fewer than 1% of all physeal injuries in children, the incidence is increasing, likely because of greater participation in high-level athletics. SUMMARY: TTAFs tend to occur in adolescents nearing skeletal maturity who engage in sports with repetitive jumping. The most popular classification system was proposed by Ogden, which defines five fracture types based on the fracture pattern and extent of fragment displacement. Treatment can be nonsurgical or surgical, and indications depend on fracture type. Most fractures are surgical candidates and can be repaired with open reduction and internal fixation (ORIF) or arthroscopy. Arthroscopic approaches can reveal associated soft tissue injuries, such as meniscal tears, and confirm articular reduction. The most common postoperative complication is irritation because of hardware. With proper treatment, both nonsurgical and surgical outcomes are excellent. TTAFs have high rates of union and patients typically return to sports.

Resumen Las fracturas de la epitróclea representan el 11 al 20% de las lesiones en codo en población pediátrica y aproximadamente el 50% se asocia a luxación en el codo, siendo la incarceración menos frecuente. El objetivo del trabajo es describir los resultados funcionales de una serie de pacientes con fractura de epitróclea. Se realizó un estudio observacional descriptivo y retrospectivo de pacientes pediátricos con fracturas de epitróclea, atendidos en un hospital pediátrico. Se revisaron las historias clínicas y los datos fueron analizados en Excel. El estudio fue aprobado por el comité de ética del hospital. Se tomaron 42 casos de los cuales 39 cumplieron con los criterios de inclusión. La edad media fue 11.3 años (4-16 años). El 77% fueron operados y la fractura se asoció a luxación del codo en el 25.6%. El 7.6% de los casos tuvieron neuroapraxia de nervio cubital con recuperación espontánea. La fractura de la epitróclea se observa en población pediátrica involucrada en actividades de alto rendimiento. Puede ocurrir falla en diagnóstico debido a la compleja osificación del codo y también a la superposición de imagen de la epitróclea con la tróclea humeral. Se asocia con luxación del codo entre un 25 a 50% de los casos. El tratamiento de esta fractura es ortopédico o quirúrgico. Las tasas de consolidación en ambos tratamientos son similares.
Abstract Medial epicondyle fractures represent 11-20% of elbow injuries in the pediatric population. Approximately 50% is associated with dislocation in the elbow. Incarceration is less frequent. The objective of this study is to describe the functional results of a cases of patients with medial epicondyle fracture and to review the subject. It is a descriptive and retrospective observational study of pediatric patients with medial epicondyle fracture, attended in a pediatric hospital. The medical records were reviewed and the data were analyzed in an Excel table. The study was approved by the hospital ethics committee. 39 of 42 cases, met the inclusion criteria. The average age was 11.3 years (4-16 years). 77% were operated and the fracture was associated with dislocation of the elbow in 25.6%. The 7.6% of the cases had ulnar nerve neuroapraxia that they recovered spontaneously. The medial epicondyle fracture is observed in the pediatric population involved in high performance activities. Subdiagnosis can occur due to the complex ossification of the elbow and also to the superimposition of the medial epicondyle image with the humeral trochlea. It is associated with dislocation of the elbow between 25 to 50% of cases. The treatment of this fracture is orthopedic or surgical. The consolidation rates in both treatments are similar.

INTRODUÇÃO: O tornozelo é considerado uma das regiões do corpo mais propensa às lesões esportivas, sendo 70% dessas lesões entorses de tornozelo. A recidiva de entorses pode provocar um prejuízo crônico na função proprioceptiva e sensório-motora. Não existe um tratamento específico para as entorses, sendo utilizados protocolos como o PRICE, abordagem passiva, imobilização da articulação e terapia manual. OBJETIVO: Trazer informações mais consistentes que elucidem os efeitos da terapia manual na recuperação da funcionalidade do paciente. MATERIAIS E MÉTODOS: Tratase de uma revisão sistemática baseada no PRISMA, com buscas realizadas nas bases de dados: PubMed, SciELO, LILACS e PEDro. Foram pesquisados apenas ensaios clínicos randomizados, com avaliação maior ou igual a 5/10 na escala PEDro, nos idioma português e inglês. Os estudos deveriam incluir população com idade entre 18 e 60 anos utilizando técnicas de terapia manual como: Mulligan, Maitland, mobilização neural, massoterapia, liberação miofascial, pompage e alongamento passivo. RESULTADOS: Foram incluídos 7 artigos com um total de 300 indivíduos. Os estudos incluídos investigaram a recuperação da funcionalidade de pacientes submetidos à terapia manual. Limitações: heterogeneidade no tempo de lesão. CONCLUSÃO: Os resultados evidenciaram melhora na capacidade física para correr, saltar, pousar e realizar movimentos de corte e laterais, melhora da cinemática, marcha, distribuição de descarga de peso e função global.
INTRODUCTION: The ankle is considered one of the regions of the body most prone to sports injuries, with 70% of these injuries ankle sprains. The recurrence of sprains can cause chronic impairment in proprioceptive and sensorymotor function. There is no specific treatment for sprains, using protocols such as PRICE, passive approach, immobilization of the joint and manual therapy. Manual therapy in patients who have undergone lateral ankle sprains can provide beneficial results by improving range of motion, subtalar joint slippage, speed and length of steps, distribution of gait forces, pain relief, and activities of daily living. OBJECTIVE: The objective of this study is to provide more consistent information that elucidates the effects of manual therapy on the recovery of the patient's functionality. MATERIALS AND METHODS: This is a systematic review that followed some PRISMA rules in the databases: PubMed, SciELO, LILACS and PEDro. The articles were searched in Portuguese and English. RESULTS: Seven articles with a total of 300 individuals were included. The included studies investigated the retrieval of the functionality of patients undergoing manual therapy. CONCLUSION: The results showed an improvement in physical ability to run, jump, land and perform lateral and lateral movements, improvement of kinematics, improvement of gait, better distribution of weight discharge and improvement of overall function.

BACKGROUND: Although open reduction and internal fixation are recommended for displaced tibial tubercle avulsion fractures in young athletes, whether to use unicortical or bicortical fixation is debatable. The purpose of this study is to compare the outcomes of unicortical versus bicortical fixation in a series of pediatric tibial tubercle avulsion fractures. METHODS: We reviewed a consecutive series of patients with tibial tubercle fractures treated surgically at 2 level-1 pediatric tertiary care centers over a 12.5-year period. Patients aged below 18 years of age who received surgical treatment for displaced tibial tubercle fractures with postoperative follow-up were included. Fractures were classified using a modified Ogden classification system. The relative proportion of fracture types treated and incidence of complications were compared. RESULTS: The cohort included 90 fractures in 86 patients. There were 82 male and 4 female individuals; average age was 14.7 years (range, 9.0 to 18 y). In total, 87 of 90 were treated with open reduction and internal screw fixation [51 unicortical (59%), 13 mixed (15%), 23 bicortical (26%)] and 3 with percutaneous pinning. All patients were followed-up until healing and postoperative follow-up average was 8 months (range, 3 to 34 mo). There were no significant differences between the 2 groups with regard to patient age (P=0.22), patient weight (P=0.22), and activity clearance times [unicortical: 19.9 wk (range, 10.4 to 42.3 wk); bicortical: 17.7 wk (range, 12.1 to 32 wk); P=0.19]. The mixed cortical group was cleared at an average of 19.9 weeks (range, 10.6 to 29.1 wk). The relative proportion of fracture patterns treated differed negligibly between the unicortical and bicortical groups. Complications were noted in 9 of 90 procedures (10% rate); all subjects showed evidence of full radiographic healing at last follow-up. CONCLUSIONS: There was no difference in outcome whether unicortical or bicortical fixation was used. All patients exhibited full healing and return to activities with very low-complication rates. The results of this study suggest the adequacy of unicortical fixation for treating tibial tubercle fractures in young athletes. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

PURPOSE OF REVIEW: The purpose of this review is to summarize and clarify the current framework for treating tibial spine avulsion fractures (TSAFs). We will discuss how these fractures are classified both on plain radiographs and MRI as well as report the incidence of concomitant soft tissue injury, an important consideration that guides treatment. We will also compare guidelines for nonsurgical versus surgical treatment and summarize frequently used surgical techniques. Finally, we will review outcomes following treatment, including common complications. RECENT FINDINGS: Although TSAFs only constitute 2-5% of all pediatric knee injuries, the incidence is increasing. A recently developed MRI-based system for evaluating TSAFs is another tool that aids in the treatment of these injuries. SUMMARY: TSAFs can be classified using plain radiographs as well as MRI. Type I fractures are usually treated with immobilization whereas type II fractures typically undergo an initial attempt at closed reduction followed by arthroscopic or open reduction and fixation if needed. Type III fractures are indicated directly for arthroscopic surgery and both suture and screw fixation produce good clinical outcomes. All-epiphyseal or transphyseal approaches can minimize the risk of physeal injury in skeletally immature patients. Common complications following TSAF injury and treatment are residual laxity, knee stiffness, and nonunion or malunion.
