Resultados del tratamiento quirúrgico de las luxaciones acromioclaviculares tipo iii mediante técnica de Weaver-Dunn modificada / Results of surgical treatment of acromioclavicular dislocations type III using modified Weaver Dunn technique

Objetivo. Valorar los resultados clínicos y radiológicos del tratamiento quirúrgico de las luxaciones acromioclaviculares tipo iii mediante la técnica de Weaver-Dunn en fase diferida. Material y método. Estudio observacional retrospectivo controlado no aleatorizado de 38 pacientes intervenidos entre enero de 2006 y diciembre de 2014. Se excluyeron 10 pacientes por fallecimiento o no localización. Se recogieron datos demográficos, tiempo hasta la intervención y complicaciones, analizando la Escala visual analógica, DASH y Oxford Shoulder Score y el resultado radiológico actualizado. Resultados. Edad media de los pacientes de 35 años con hombro derecho-dominante afectado en un 71% de los casos predominantemente por caídas no a nivel. El 70% de los casos tenían percepción subjetiva tanto de recuperación de fuerza como de desaparición de deformidad. Se objetivó reducción completa radiológica en un 95% de los casos, con aparición de artrosis leve en un 44% y moderada en un 5,6%. Los resultados del DASH presentaron valores de 12,939 (±16,851) y el OSS de 42,736 (±7,794), indicando una función articular satisfactoria. Discusión. Los datos de este estudio muestran similitud en cuanto a resultados de estudios anteriores en lo que respecta a la recuperación subjetiva de la fuerza, mantenimiento de la reducción anatómica, resultados de test funcionales y eficacia de la técnica de Weaver-Dunn. Conclusiones. La técnica de Weaver-Dunn modificada aportó buenos resultados clínicos y radiológicos con reincorporación del paciente a sus actividades habituales y su mantenimiento a lo largo del tiempo (AU)

Objective. To evaluate the clinical and radiological results of the surgical treatment of type III acromioclavicular dislocations using the Weaver-Dunn technique in the delayed phase. Material and method. A non-randomised controlled retrospective observational study of 38 patients operated between January 2006 and December 2014. We excluded 10 patients due to death or non-localisation. We collected demographic data, time to intervention, complications, analysing the Visual Analog Scale, DASH and Oxford Shoulder Score and the updated radiological result. Results. mean age of patients with right-dominant shoulder affected in 71% of cases predominantly by non-level falls was 35. 70% of the cases had subjective perception of both recovery of strength and disappearance of deformity. Full radiological reduction was observed in 95% of the cases with the appearance of mild osteoarthritis in 44% and moderate osteoarthritis in 5.6%. The results of the DASH presented values of 12,939 (±16,851) and the OSS of 42,736 (±7,794), indicating satisfactory articular function. Discussion. The data from this study shows similar results to previous studies regarding subjective recovery of strength, maintenance of anatomical reduction, functional test results and efficacy of the Weaver-Dunn technique. Conclusions. The modified Weaver-Dunn technique provided good clinical and radiological results with patient reincorporation to their usual activities and maintenance over time (AU)

Enfermedad de Sinding-Larsen-Johansson: análisis de factores asociados / Sinding-Larsen-Johansson disease: analysis of the associated factors

Objetivo. Analizar los factores clínicos, etiológicos biomecánicos asociados a la enfermedad de Sinding-Larsen-Johansson (SLJ). Material y método. Estudio de casos-control valorando los siguientes parámetros: edad, sexo, tiempo de evolución clínica, lateralidad, nivel de actividad deportiva, grado radiológico, existencia de patela alta, existencia de retracción de isquiotibiales y aumento de la caída posterior de la tibia. Resultados. Presentamos 15 rodillas en 14 pacientes (un caso de afectación bilateral). El porcentaje de varones es del 85,7% y la edad media de afectación es de 10,86 años (d.t. 1,61). Todos ellos presentaban un nivel de actividad física y deportiva elevado con una duración de los síntomas muy variable (1-36 meses). Sin tendencia clara en cuanto a la lateralidad, la mayoría se incluyen en un grado radiológico tipo ii (53,3%). El análisis de los datos no muestra diferencias significativas (p>0,05) entre los grupos respecto al índice de Caton ni de Insall modificado. En la medición del ángulo poplíteo en las rodillas lesionadas, sí encontramos diferencias significativas (media: 32,50 d.t.:8,90) con respecto al grupo control (17,67; 8,21). La diferencia en la medición del ángulo de caída posterior en las rodillas lesionadas también ha resultado estadísticamente significativo (10,47; 2,82) con respecto a las rodillas de los casos control (8,33; 1,40). Conclusiones. Los pacientes con la enfermedad tienen un aumento de la pendiente tibial y retracción de isquiotibiales respecto al grupo control y esta diferencia es estadísticamente significativa (AU)

Aim. To analyse the clinical symptoms, aetiology and biomechanical aspects related to Sinding-Larsen-Johansson (SLJ) disease. Material and method. A case control study was conducted, analysing the following variables: age, gender, clinical follow up, side of body with the symptoms, sporting activity, radiological stage, presence of patella alta, presence of short hamstring tendons, and increased posterior tibial slope. Results. A total of 15 knees in 14 patients were studied; one case with bilateral disease. The large majority of cases were 85.7% were male, and the mean age was 10.86 (standard deviation 1.61). All of them practised sport and physical activity at a high level with a variable duration of symptoms (1-36 months). There was predominance in side. The majority were radiological grade II (53.3). The data analysis did not show any significant difference (P>.05) between the study groups regarding the Caton and modified Insall indexes. There was a significant difference in the popliteal angle measured in the affected knees (mean: 32.50, SD: 8.9) compared with the control group (mean: 17.67, SD: 8.21). The difference in the posterior slope angle in the affected knees was also statistically significant (mean: 10.47, SD: 2.82) compared with the control (mean: 8.33, SD: 1.4). Conclusions. According to our data, patients have short hamstring tendons and increased posterior tibial slope compared to the control group, and this difference is statistically significant (AU)
