RESUMEN

Background: Hereditary multiple osteochondromas (HMOs) are a rare genetic disorder characterized by the formation of multiple benign osteochondromas that can undergo malignant transformation into chondrosarcoma. Case Description: A 24-year-old male with a history of HMO and osteochondroma surgery 4 years ago, presented with back pain and paresthesias. The magnetic resonance showed a right paravertebral infiltrating mass at the T12-L1 level causing spinal cord compression. Following en bloc resection of the tumor, the patient's symptoms/ signs resolved. The final pathological diagnosis was consistent with a chondrosarcoma. Conclusion: Chondrosarcomas secondary to HMO with spinal cord compression are rare. These patients often presenting with significant myelopathy/cord compression should undergo gross total resection where feasible to achieve the best outcomes.

RESUMEN

INTRODUCTION: to evaluate the long term radiographic and functional results achieved in adult patients with osteoporotic, atrophic, non-unions of the diaphyseal humerus, treated surgically by open reduction and internal fixation with plates and bone graft. MATERIAL AND METHODS: we retrospectively evaluated 22 patients. Patient's age averaged 72 years. Time from initial trauma to definitive surgery averaged 18 months. Eleven patients were smokers, and four had active infection. Pre-operative Constant score and DASH score averaged 23.13 and 81.04, respectively. Pre-operative pain scale averaged 7.45 points. RESULTS: follow-up averaged 69 months. Union was achieved in all cases after an average of 4.68 months. DASH score at last follow-up averaged 20.27 points and Constant score 79.31 points. Analog pain scale averaged 0.77 points. Stabilization was performed using locking blade plates in 12 non-unions, locking compression plates in six cases, and double plating in four non-unions. Patients with active infection were treated in two stages using Masquelet's technique. Bone graft was associated in all cases (cancellous iliac crest autograft in 17, allograft in three, and combined structural allograft and cancellous autograft in two). Two grams of vancomycin powder were associated to the bone graft in all cases. CONCLUSION: the use of open reduction and internal fixation with plates associated to bone graft with local antibiotics, aloud achieving bony union and good predictable long-term objective and subjective functional results in all cases, without major complications or the need of further surgical intervention.

RESUMEN

Introducción: Las fracturas humerales diafisarias multifragmentarias con extensión proximal son patrones infrecuentes de lesión causados principalmente por trauma de alta energía. La forma anatómica del húmero, la presencia de la tuberosidad deltoidea y la proximidad del nervio radial al surco radial representan retos a tratar, por ello se recomiendan incisiones mínimamente invasivas y la estabilización de la fractura con placa proximal humeral internal locking system. Objetivo: Demostrar la eficacia de la técnica minimally invasive plate osteosynthesis con el moldeamiento helicoidal de la placa proximal humeral internal locking system. Presentación del caso: Paciente de 29 años que sufrió accidente de tránsito y presentó fractura diafisaria multifragmentaria extendida al húmero proximal. Se trató con la técnica minimally invasive plate osteosynthesis y placa helicoidal proximal humeral internal locking system. Alcanzó la consolidación completa y rápida recuperación funcional. Conclusiones: La técnica minimally invasive plate osteosynthesis con placa helicoidal proximal humeral internal locking system es una opción quirúrgica eficaz y segura para las fracturas humerales diafisarias multifragmentarias con extensión proximal, ya que preserva la inserción muscular deltoidea, mejora el contacto placa hueso con riesgo mínimo de lesión neurológica axilar y radial, favorece la curación ósea y mejora el resultado funcional.

Introduction: Multifragmentary diaphyseal humeral fractures with proximal extension are infrequent patterns of injury caused mainly by high-energy trauma. The anatomical shape of the humerus, the presence of the deltoid tuberosity and the proximity of the radial nerve to the radial groove represent challenges to be treated, therefore minimally invasive incisions and fracture stabilization with the proximal humeral internal locking system plate are recommended. Objective: To establish the efficacy of the minimally invasive plate osteosynthesis technique with helical molding of the proximal humeral plate internal locking system. Case report: We report the case of a 29-year-old patient who suffered a traffic accident and had a multifragmentary diaphyseal fracture extended to the proximal humerus. He was treated with the minimally invasive plate osteosynthesis technique and the humeral proximal helical plate internal locking system. He achieved complete consolidation and rapid functional recovery. Conclusions: The minimally invasive plate osteosynthesis technique with the humeral proximal helical plate internal locking system is an effective and safe surgical option for multifragmentary diaphyseal humeral fractures with proximal extension, since it preserves the deltoid muscle insertion, improves bone-plate contact with minimal risk of fracture. Axillary and radial neurological injury, promotes bone healing and improves functional outcome.

RESUMEN

Resumen: Introducción: el estándar de oro de tratamiento para la mayoría de las fracturas diafisarias de tibia está representado por el clavo endomedular (CEM). El objetivo de este estudio fue analizar la importancia del diámetro del CEM sobre la consolidación de fracturas diafisarias de tibia. Material y métodos: se realizó un estudio retrospectivo en pacientes con fracturas cerradas de tibia 42 OTA/AO, tratados con un CEM fresado y acerrojado, entre Enero de 2014 y Diciembre de 2020. Las variables analizadas fueron género, edad, comorbilidades, cantidad de cerrojos utilizados, relación clavo/canal (diferencia entre el diámetro del canal medular y clavo), el índice clavo/canal (razón entre diámetro del clavo y el canal medular), en relación con la tasa de consolidación y falla (retardo de consolidación y seudoartrosis). Resultados: la serie final se conformó por 96 pacientes y la tasa de consolidación fue de 91.7% (n = 88). Se observó un diámetro de clavo significativamente mayor en los pacientes que consolidaron respecto a los que fallaron (p = 0.0014), incrementando la posibilidad de consolidación 5.30 (p = 0.04) veces, por cada milímetro que el clavo aumentó su diámetro. Se observó un incremento de probabilidad de consolidación de 13.56 (p = 0.018) veces utilizando un clavo > 10 mm de diámetro. El índice clavo/canal ≥ 0.80 aumentó la posibilidad de consolidación 23.33 veces (p = 0.005). Conclusión: nuestros hallazgos sugieren que los CEM fresados y acerrojados en fracturas diafisarias de tibia deben colocarse del mayor diámetro posible (> 10 mm y con un índice clavo/canal ≥ 0.80) para favorecer la consolidación.

Abstract: Introduction: the gold standard for tibial diaphyseal fracture treatment is represented by the intramedullary nail (IMN). This study aimed to assess the relevance of nail diameter in bone healing of tibial diaphyseal fractures. Material and methods: a retrospective study was conducted analyzing patients with closed 42 OTA/AO tibial fractures, treated with a reamed and locked IMN between January 2014 and December 2020. The variables assessed were gender, age, comorbidities, number of bolts used, canal/nail index (difference between the diameter of the medullary canal and nail), nail/canal ratio (ratio between nail diameter and medullary canal), related to consolidation and failure rates (delay - and non-union). Results: 96 patients were included. The consolidation rate was 91.7% (n = 88). Patients with consolidation had a significantly larger nail diameter than those who failed (p = 0.0014), increasing the chance of consolidation 5.30 (p = 0.04) times for each millimeter that the nail increased its diameter. Using a nail > 10 mm increased the chance of consolidation 13.56 times (p = 0.018). A nail/canal ratio ≥ 0.80 increased the chance of consolidation 23.33 times (p = 0.005). Conclusion: our findings suggested that reamed and locked IMN in tibial diaphyseal fractures should be implanted with the largest possible diameter (> 10 mm and with a nail-to-canal ratio ≥ 0.80) to promote bone healing.

RESUMEN

OBJECTIVE: The objective of this study was to determine the location, number, and direction of the nutrient foramen in the humerus, radius, femur, and tibia bones of mixed breed dogs. MATERIALS AND METHODS: The humerus, radius, femur, and tibia of both (left and right) limbs of mixed breed dogs were examined in this study. The number, location, and direction of the nutrient foramina were identified. Once identified, the diameter of each nutrient foramen was measured and the site index calculated. RESULTS: Only one nutrient foramen was identified in the humerus, radius, tibia, and right femur, while the foramen numbers ranged from one to three in the left femurs examinated. The nutrient foramen was localized on the caudal surface in the radii, femurs, tibias, and left humeri. Contrasting, however, 75% were located on the caudal surface of the right humeri and 25% on the lateral surface. The average diameter of the nutrient foramen of the humerus ranged from 0.88 to 1.00 mm, while it ranged from 1.13 to 1.25 mm in the radius. On the hind limb, the diameter of the nutrient foramen on the femur ranged from 1.2 to 1.3 mm and 0.75-1.25 mm on the tibia. The nutrient foramen was directed towards the corresponding joint in 100% of the humeri and tibias, 75% of the radii, and 60%-80% of the femurs examined. CONCLUSION: The anatomical data on the nutrient foramen obtained in this study will be valuable for veterinarians when diagnosing pathological bone lesions and for orthopedic surgery.

RESUMEN

OBJECTIVE: The objective of the present study was to identify patterns of femoral diaphyseal fractures which are associated with fractures of the ipsilateral femoral neck according to the AO classification. We propose an algorithm of investigation based on plain radiographs, recognizing cases that need additional screening with computed tomography. PATIENTS AND METHODS: This observational retrospective study included patients with combined diaphyseal and femoral neck fractures. These patients were retrieved from a total of 1398 patients with the diagnoses of diaphyseal fractures of the femur, who were admitted to our hospital for surgical treatment between January 2009 and October 2019. All included cases had both fractures analyzed for their geometry and were classified according to the AO Classification, seeking to find a correlation between the types of fractures. RESULTS: Sixteen diaphyseal fractures associated with ipsilateral neck fractures were detected during the period. The distribution of the diaphyseal fractures according to the AO Classification was as follows: 5 of type A3 (31,2%) 6 type B2 (37.5%), 1 type B3 (6,2%), 2 type C2 (12,5%) and 2 type C3 (12,5%). One A2 femoral fracture occurred during the surgical procedure. No type A1 fractures were detected. CONCLUSION: The patterns of high-energy diaphyseal fractures (A3, B and C) have a higher prevalence of associated ipsilateral neck fractures. Our study suggests that routine additional methods of image investigation of femoral neck fractures may be unnecessary for diaphyseal fractures type A1 and A2.

RESUMEN

OBJECTIVES: Gender differentiation can influence the diet, physical activity, and health of human populations. Multifaceted approaches are therefore necessary when exploring the biological consequences of gender-related social norms in the past. Here, we explore the links between diet, physiological stress, physical activity, and gender differentiation in the Medieval Islamic population of La Torrecilla (Granada, Spain, 13th-15th century AD), by analyzing stable isotope patterns, stature, and long bone diaphyseal measurements. MATERIALS AND METHODS: The sample includes 96 individuals (48 females, 48 males) classified as young and middle adults (20-34 and 35-50 years of age respectively). Diet was reconstructed through the analysis of δ13 C and δ15 N. Stature, humeral and femoral diaphyseal shape and product of diaphyseal diameters served as proxies of physiological stress and physical activity. RESULTS: Isotopic ratios suggest a substantial dietary contribution of C4 plants (e.g., sorghum, millet), a variable access to animal proteins, and no differences between the sexes. Sexual dimorphism in stature derives from a markedly low female stature. Long bone diaphyseal properties suggest that men performed various physically stressful activities, whereas women were involved in less physically demanding activities (possibly related to household work). DISCUSSION: Gender differentiation in La Torrecilla was expressed by a possibly differential parental investment in male versus female offspring and by culturally sanctioned gender differences in the performance of physical tasks. Diet was qualitatively homogenous between the sexes, although we cannot rule out quantitative differences. Our results shed new light on the effects of gender-related social norms on human development and lifestyle.

RESUMEN

BACKGROUND: High-energy tibial plateau fractures are challenges in treatment with controversy over operative stabilisation, especially for fractures with metaphyseal-diaphyseal dissociation. Treatment with percutaneous or minimally invasive direct reduction techniques, usually associated with circular external fixation, has generated interest although there is no consensus regarding the type of external fixation to be used. AIM: This study aims to compare the two hybrid circular external fixation mountings used to treat the high-energy tibial plateau fractures. METHODS: Two different groups of hybrid circular external fixation frame mountings were assembled using composite tibiae with proximal metaphyseal osteotomies simulating tibial plateau fractures with metaphyseal-diaphyseal dissociation. The standard all-wire frame mounting was assembled, and the comparison frame mounting had the distal K-wires replaced with half-pins. Both groups were tested through cyclic loading between 300 and 1000 N for 10,000 cycles. Interfragmentary linear and rotational displacements were analysed. RESULTS: The standard frame mounting behaved similarly to a classic Ilizarov frame, allowing greater axial movement (mean, 3.76 ± 0.26 mm in the standard group and 3.02 ± 0.23 mm in the test group) and smaller mediolateral displacement compared with the test frame (mean, 0.17 ± 0.16 mm compared to 0.56 ± 0.12 mm). The test frame behaved more similarly to a linear external fixator and provided greater axial stability, similar anteroposterior displacement, and lower mediolateral stability. Despite these differences, in both groups the axial displacement was greater than the prejudicial nonaxial movements. CONCLUSION: Increasing the number of half-pins and decreasing the number of K-wires in hybrid circular external fixation generate frames that tend to behave more similarly to the linear external fixators.

RESUMEN

INTRODUCTION: The purpose of this study was to evaluate the results achieved after the use of lateral minimally invasive plate osteosynthesis (MIPO) in oligotrophic humerus nonunions resulting from failed intramedullary nailing (IM). METHOD: We evaluated nine patients with humerus nonunion after failed locked intramedullary nailing, all treated using 3.5-mm locked compression plates (LCP) placed through lateral minimally invasive approaches, between 2010 and 2016. Patient's age averaged 39.7 years. All nonunions were diaphyseal and oligotrophic. All nonunions had previous surgical treatment with static locked nails (seven antegrade and two retrograde). The IM nails were all well inserted in the humerus (none of them protruded or had rotator cuff lesions associated). Pre-operative Disabilities of the Arm, Shoulder and Hand (DASH) score averaged 25.5 points. Pre-operative Constant's score averaged 80.2. Pre-operative visual analog scale of pain averaged 2.4 points. RESULTS: Follow-up averaged 17.7 months. Time between initial surgery and revision procedure averaged 11.7 months. Union was achieved in all cases, after an average of 4.8 months. DASH score at last follow-up averaged 5.1 points, and final Constant's score averaged 93.7 points. The analog scale of pain averaged 0.7 points. Time from definitive surgery to work return averaged 3.9 months. Long 3.5-mm LCPs were used (plate length averaged 16.9 screw holes). In two cases, a third 4-cm incision at the nonunion site was performed and cancellous autologous iliac crest bone graft was associated. CONCLUSION: In our series of nine patients, we achieved union and good objective and subjective results, with high patient satisfaction, using a lateral MIPO technique and placing long 3.5-mm LCPs in selected oligotrophic humerus nonunions after failed IM nailing.

RESUMEN

Metric standards are presented for the estimation of fetal age at the time of death in the Mexican population. To obtain these standards, both metric and radiological studies were conducted on 97 fetuses and complete stillborn infants of both sexes, phenotypically normal between 10 and 38 weeks of morphological age. All the fetuses used were the product of spontaneous abortions in Mexico City between 1990 and 2000. Equations were obtained by calibrating quadratic linear regression models adjusted for the diaphyseal length of the humerus, radius, ulna, femur, tibia and fibula, characterized as the most adequate indicators to represent the growth of long bones in this age group, and verified by the evaluation of the model assumptions and the coefficient of determination (R(2)). To conclude, these models facilitate a more precise prediction in fetuses of the Mexican population, constituting the first metric standards of their type at a national level.

En la serie predominaron el sexo masculino (74,0 %), el grupo etario de 26-35 años (37,4 %), los accidentes de tránsito como causa principal de las lesiones (74,0 %) y la reducción de la fractura de forma abierta (90,2 %); asimismo, 29,4 % de los pacientes presentó complicaciones y 80,5 % mostró buenos resultados en la evaluación final. Finalmente, se pudo concluir que el uso del clavo intramedular de Küntscher sin fresado del canal, es una técnica quirúrgica viable para solucionar las fracturas diafisarias de tibia.

A descriptive, longitudinal and retrospective study of 123 patients with tibial diaphyseal fracture who were surgically treated by means of the surgical technique of fixation with Küntscher intramedullary nail without reaming of channels was carried out from August, 2012 to December, 2013, in Tumbi Special Hospital, Kibaha, Tanzania, with the aim of evaluating the results of this procedure. The male sex (74.0%), the age group 26-35 years (37.4%), the traffic accidents as main cause of the lesions (74.0%) and the reduction of the fracture in an open way (90.2%) prevailed in the series; also, 29.4% of the patients presented complications and 80.5% showed good results in the final evaluation. Finally, it could be concluded that the use of Küntscher intramedullary nail without reaming channels, is a viable surgical technique to solve the tibial diaphyseal fractures.

RESUMEN

Se realiza un estudio abierto, observacional, descriptivo, tipo serie clínica en el IAHULA, Mérida, Venezuela, en pacientes adultos tratados quirúrgicamente por fracturas de antebrazo durante el 2012, se vaciaron en una base de datos sistematizada traumatológica, HICLINEL ®, demostrando su eficacia y utilidad. Se incluyeron 40 pacientes, 42 casos. 85% pacientes y 85,7% casos fueron controlados. 82,5% de sexo masculino. Edad promedio 29,4 años. 25% obreros. 45% por hechos viales en moto. 16,7% fueron fracturas 22A3.2. 100% tratados mediante reducción directa, 97,5% se realizo osteosíntesis con placa. 100% y 91,2% tuvieron escalas de MAYO excelente para codo y muñeca, respectivamente. 88,9% tuvo consolidación total. 8,8% presentaron complicaciones. En el manejo de estas fracturas en nuestra institución el implante de elección son las placas rectas de pequeños fragmentos bajo una reducción directa, obteniéndose resultado funcionales postoperatorios excelentes con consolidación completa. El HICLINEL® se sometió a valoración, generando datos estadísticos con buen desempeño(AU)

We performed an open-type series per se clinic in IAHULA, Merida, Venezuela, with adult patients surgically treated for forearm fractures during 2012, which were emptied into a trauma database systematized HICLINEL ® demonstrating their effectiveness and usefulness. We included 40 patients, 42 cases. 85% and 85,7% cases patients were monitored. Male 82,5%. Average age of 29.375 years. 25% workers. 45% by road motorcycle events. 22A3.2 16,7% were fractures. 100% were treated by direct reduction, 97,5% were performed plate fixation. 100% and 91,2% MAYO scales had excellent elbow and wrist, respectively. 88,9% was full consolidation. 8,8% had complications. In the management of diaphyseal forearm fractures in our institution the implant of choice are straight plates of small fragments under direct reduction, obtaining excellent postoperative functional outcome with their complete consolidation. HICLINEL ® system underwent assessment with the ability to generate statistical data, showing a good performance(AU)

RESUMEN

Introducción: El enclavado endomedular fresado anterógrado es el método de elección para el tratamiento de las fracturas diafisarias de fémur. Sin embargo, la técnica retrógrada surgió como alternativa para situaciones en las que la técnica anterógrada tiene ciertas desventajas. Materiales y Métodos: Entre marzo de 2001 y enero de 2011, se realizaron 110 enclavados retrógrados de fémur, 34 de ellos en pacientes con fracturas diafisarias de fémur. Los mecanismos de lesión fueron: colisión vehicular (15 casos), traumatismo de baja energía (18 casos) y proyectil de arma de fuego (1 caso). Once pacientes (31 %) tenían lesiones asociadas. Resultados: Treinta y tres pacientes consiguieron la consolidación ósea (97 %). El tiempo medio de consolidación fue de 84 días para los clavos fresados y de 112 días para los no fresados. Hubo un caso de retraso de la consolidación. El rango de movilidad de la rodilla promedio fue de 130º de flexión (mínimo 100º y máximo 150º). Seis pacientes (17,6 %) refirieron dolor de rodilla. Conclusiones: El clavo retrógrado para el tratamiento de fracturas diafisarias de fémur consigue resultados de consolidación similares a los del clavo anterógrado de fémur. Sus posibles ventajas son la técnica simple, un menor tiempo quirúrgico y la posibilidad de operar sin el uso de una mesa de tracción.

Background: The antegrade intramedullary reamed nailing is the method of choice for treating diaphyseal femoral fractures. nevertheless, the retrograde technique has emerged as an alternative for situations in which the antegrade one presents certain disadvantages. Methods: Between March 2001 and January 2011, 110 femoral retrograde nailings were performed. thirty-four were performed in patients with diaphyseal femoral fractures. Mechanisms of injury were vehicular collision (15 cases), low energy trauma (18 cases) and ballistic trauma (1 case). Eleven patients (31 %) presented associated injuries. Results: thirty-three patients achieved consolidation (97 %). Healing after procedure occurred at 84 days for the reamed group and 112 for the undreamed one. We had one case of consolidation delay that was resolved inserting a larger diameter reamed nail together with autologous graft. The average range of motion was 130º of flexion (minimum 100º, maximum 150º). Six patients (17.6 %) reported knee pain. Conclusions: the retrograde nailing for diaphyseal femoral fractures yields consolidation results similar to those of the antegrade nailing. the possible advantages are: simple technique, the avoidance of traction table use during surgery and shorter surgical time.

RESUMEN

A doença de Camurati-Engelmann é uma displasia diafisária progressiva, autossômica dominante, caracterizada por progressiva expansão cortical e esclerose, que afeta, na maioria das vezes, as diáfises dos ossos longos, associada à hiperostose craniana. As manifestações clínicas são dor óssea nos membros inferiores, fraqueza muscular e atrofia muscular. Os autores relatam um caso de doença de Camurati-Engelmann em paciente masculino, de um ano de idade com diagnóstico avaliado pela radiografia simples, tomografia computadorizada, cintilografiaóssea e exames laboratoriais durante oito anos de evolução da doença. Ressalta-se a importância do diagnóstico diferencial com outras doenças que cursam com hiperostose e o emprego de corticosteroide para controle do quadro álgico.

Camurati-Engelmann disease is a rare progressive diaphyseal dysplasia, autosomal dominant, characterized by progressive cortical expansion and sclerosis mainly affecting the diaphysis of the long bones associated with cranial hyperostosis. The clinical manifestations are lower limbs bone pain, muscle weakness and muscular atrophy. The authors report a case of Camurati-Engelmann disease in a 1-year-old male patient who was submitted to plain radiography, computed tomography, bone scintigraphy and laboratory exams for eight years. The authors emphasize theimportance of the differential diagnosis with other diseases that attend hyperostosis and the use of corticosteroids to control the pain.
