Tratamiento de las fracturas diafisarias extraarticulares de húmero distal por abordaje posterior modificado y placa extraarticular / Surgical treatment of extra-articular distal-third diaphyseal fractures of the humerus using a modified posterior approach and an extra-articular plate

Objetivo. Evaluar los resultados clínicos y radiológicos del tratamiento quirúrgico de las fracturas diafisarias extraarticulares de húmero distal tratadas mediante un abordaje posterior modificado con una placa extraarticular preconformada de húmero distal. Material y métodos. Realizamos un estudio retrospectivo entre los años 2013 y 2015 de 23 pacientes mayores de 18 años, 45 años de media, con diagnóstico de fractura extraarticular de húmero distal que fueron intervenidos quirúrgicamente en nuestro centro mediante abordaje posterior modificado de Gerwin y placa extraarticular de húmero distal con seguimiento mínimo de un año y seguimiento medio de 18 meses. Se excluyeron las fracturas patológicas. Se recogieron los datos demográficos, el tipo de fractura, la lateralidad, el mecanismo de producción y la presencia de parálisis radial. Se evaluó el resultado clínico-funcional con las escalas Quick-Dash (QD), MEPS y EVA, el resultado radiológico y el tiempo hasta la consolidación. Se recogieron la satisfacción (sí o no) y las complicaciones. Resultados. Seis pacientes presentaban fractura tipo 12-A, 7 tipo 12-B y 10 tipo 12-C. Todos los pacientes presentaron consolidación al año de la intervención (media 12 semanas). Nueve pacientes presentaron parálisis radial prequirúrgica y uno posquirúrgica. No hubo complicaciones relacionadas con fracasos de material y se observaron 2 infecciones de herida quirúrgica. La puntuación media de las escalas fue la siguiente: QD 6,43, EVA 0,66, MEPS 88,88; 12 resultados fueron considerados como excelentes, 3 como buenos y 3 como suficientes. Conclusión. La osteosíntesis de este tipo de fracturas con placa extraarticular empleando el abordaje de Gerwin presenta una tasa de complicaciones muy baja, permite la exploración del nervio radial con una buena exposición proximal del húmero, permite reducción anatómica con montaje rígido y estabilización absoluta de la fractura, dejando libre las articulaciones, obtiene altas tasas de consolidación con excelentes resultados funcionales y una rápida vuelta a la actividad de los pacientes (AU)

Purpose. To evaluate the clinical and radiological outcomes of these fractures treated through a modified posterior approach with a distal humerus plate. Material and methods. Between 2013 and 2015 we performed a retrospective study of these fractures surgically treated in our centre. Inclusion criteria: older than 18 years old, no pathological fractures, follow up 1 year at least. 23 patients underwent surgery, mean age 45 years old, with an average follow-up of 18 months. Patient characteristics, aetiology and type of fractures were recorded. The surgery was performed using Gerwin modified posterior approach with a posterolateral distal humerus plate. Clinical results were evaluated using Quick DASH, MEPS, VAS. Radiological results were also evaluated. Complications associated with treatment and radial nerve palsy incidence were recorded as well. Results. Type of fracture according AO/OTA: six 12-A, seven 12-B, ten 12-C. 23 patients progressed to union. After one year: QD 6.43, VAS 0.66, MEPS 88.88. No failure of internal fixation. Two superficial infections. 15 excellent results, 5 good, and 3 fair, with no poor results. Conclusion. Surgical fixation of these fractures through a modified posterior approach with a posterolateral plate minimises iatrogenic nerve injury, provides better visualisation of the proximal humerus, provides stable fixation of these injuries and results in high union rates and overall excellent functional results (AU)

Inestabilidad crónica de tobillo: reparación anatómica artroscópica / Chronic ankle instability: arthroscopic anatomical repair

Introducción. Los esguinces de tobillo son una de las patologías traumatológicas más frecuentes. A pesar de un tratamiento conservador adecuado, este fracasa en el 20-40% de los casos. Estos pacientes suelen desarrollar una inestabilidad crónica de tobillo. En el 75-80% de las ocasiones existe una rotura aislada del ligamento talofibular anterior. Material y método. Estudio retrospectivo observacional de 21 pacientes intervenidos quirúrgicamente mediante técnica de reparación anatómica artroscópica, por inestabilidad lateral crónica de tobillo, entre mayo de 2012 y enero de 2013. Se realizó un seguimiento medio de 29 meses (rango de 25-33). La distribución por sexos fue de 15 hombres y 6 mujeres; la edad media fue de 30,43 años (rango de 18-48). En 4 pacientes (19%), se diagnosticó una deformidad en varo del retropié asociada. En 15 pacientes (71,4%), se diagnosticaron lesiones intraarticulares: 6 pacientes presentaron lesiones osteocondrales (LOC) talares, 3 presentaban un pinzamiento posterior de tobillo y 6 pacientes presentaban distintas patologías de los tendones peroneos. Todas estas lesiones fueron abordadas quirúrgicamente en el mismo acto quirúrgico. Resultados. Se llevó a cabo una revisión clínico-funcional, utilizando la escala American Orthopaedic Foot and Ankle Society (AOFAS). La media preoperatoria fue de 66,12 puntos (rango de 60-71) y la postoperatoria se incrementó hasta una media de 96,95 puntos (rango de 90-100). Todos los pacientes pudieron retomar sus actividades deportivas previas en una media de 21,5 semanas (rango de 17-28). Encontramos complicaciones en 3 pacientes (14%). Conclusiones. La reparación anatómica del ligamento talofibular anterior mediante esta técnica presenta unos resultados clínico-funcionales excelentes, con una temprana reincorporación del paciente a sus actividades deportivas y un bajo índice de reintervenciones y complicaciones (AU)

Introduction. Ankle sprains are one of the most common injuries. Despite appropriate conservative treatment, approximately 20-40% of patients continue to have chronic ankle instability and pain. In 75-80% of cases there is an isolated rupture of the anterior talofibular ligament. Material and method. A retrospective observational study was conducted on 21 patients surgically treated for chronic ankle instability by means of an arthroscopic anatomical repair, between May 2012 and January 2013. There were 15 men and 6 women, with a mean age of 30.43 years (range 18-48). The mean follow-up was 29 months (range 25-33). All patients were treated by arthroscopic anatomical repair of anterior talofibular ligament. Four (19%) patients were found to have varus hindfoot deformity. Associated injuries were present in 13 (62%) patients. There were 6 cases of osteochondral lesions, 3 cases of posterior ankle impingement syndrome, and 6 cases of peroneal pathology. All these injuries were surgically treated in the same surgical time. Results. A clinical-functional study was performed using the American Orthopaedic Foot and Ankle Society (AOFAS) score. The mean score before surgery was 66.12 (range 60-71), and after surgery it increased up to a mean of 96.95 (range 90-100). All patients were able to return to their previous sport activity within a mean of 21.5 weeks (range 17-28). Complications were found in 3 (14%) patients. Conclusions. Arthroscopic anatomical ligament repair technique has excellent clinical-functional results with a low percentage of complications, and enables patients to return to their previous sport activity within a short period of time (AU)

Estudio comparativo de la reparación de la rotura de espesor completo del supraespinoso mediante técnica "hilera simple" o "suture bridge" / Comparative study of the repair of full thickness tear of the supraspinatus by means of "single row" or "suture bridge" techniques

Resumen: Objetivo: Analizar si existen diferencias clínicas entre las técnicas "hilera simple" versus "suture bridge" en la reparación artroscópica de roturas de espesor completo del supraespinoso. Material y métodos: Estudio retrospectivo de 123 pacientes con rotura de espesor completo del supraespinoso, intervenidos entre Enero de 2009 y Enero de 2013 (60 hilera simple y 63 suture bridge). La edad media en el grupo suture bridge fue 63.3 años y en el grupo hilera simple, 62.9. Predominio de mujeres (67%) en ambos grupos. En todos los casos, se reparó la hilera medial con anclajes Bio-Corkscrew y la hilera lateral con implantes Bio-PushLock (Arthrex, Naples, FL). Resultados: El valor del test de Constant medio en individuos intervenidos mediante suture bridge fue 76.7 (ponderado 96.5). En hilera simple, fue 72.4 (ponderado 92.8). Se realizó también un análisis estadístico comparativo de cada ítem del test de Constant por separado. La fuerza es el único parámetro del test de Constant estadísticamente significativo y es mayor en el grupo suture bridge. Conclusiones: La reparación de las roturas de espesor completo del supraespinoso mediante suture bridge proporciona resultados clínicos superiores a la reparación en hilera simple, sin existir diferencias estadísticamente significativas (p = 0.298).

Abstract: Purpose: The purpose of this study is to analyze if there is any difference between the arthroscopic reparation of full-thickness supraspinatus tears with simple row technique versus suture bridge technique. Material and methods: We accomplished a retrospective study of 123 patients with full-thickness supraspinatus tears between January 2009 and January 2013 in our hospital. There were 60 simple row reparations, and 63 suture bridge ones. Results: The mean age in the simple row group was 62.9, and in the suture bridge group was 63.3 years old. There were more women than men in both groups (67%). All patients were studied using the Constant test. The mean Constant test in the suture bridge group was 76.7, and in the simple row group was 72.4. We have also accomplished a statistical analysis of each Constant item. Strength was higher in the suture bridge group, with a significant statistical difference (p < 0.04). The range of movement was also greater in the suture bridge group, but was not statistically significant. Conclusions: Suture bridge technique has better clinical results than single row reparations, but the difference is not statistically significant (p = 0.298).
