ABSTRACT

Femoroacetabular regularization in hip impingement is currently performed by means of trochanter osteotomy and hip dislocation or more recently by means of hip arthroscopy. We present a novel alternative through a unique mini-invasive anterior approach. Our first series consisted of 35 hips (32 patients) with a mean follow-up of 29.2 months. Range of motion (ROM) and clinical scores were evaluated preoperatively at six weeks, three months, six months and one-year follow-up (FU). Impingement test was negative in 33 out of 35 cases six weeks after surgery. Mean hospitalisation time was 2.6 days (2-5 days). Mean improvement in internal rotation was 23 degrees (p=0.006) and 21 degrees in flexion (p=0.011). There was a significant improvement in hip score according to the Merle d'Aubign evaluation (13.8 points preoperative vs. 16.9 at one-year visit) (p=0.017). No Trendelenburg, heterotopic calcifications or osteonecrosis were observed. Complications related to the femorocutaneous nerve appeared in six cases (17.1%) although all but one were neuroapraxia and disappeared before one year. Mean rehabilitation time was 4.4 weeks. We conclude that the anterior surgical approach for the treatment of femoroacetabular impingement enables early resumption of sport while accuracy in bone resection is maintained.

ABSTRACT

Objetivo. Valorar la potencia de aparato extensor en la revisión de artroplastia total de rodilla (ATR) entre el abordaje parapatelar medial y el abordaje con osteotomía rotuliana. Material y método. Se realiza un estudio retrospectivo sobre 22 pacientes. El seguimiento medio fue 24,6 meses y edad media 70,2 años. Resultados. Existe un déficit mayor en la potencia extensora con la vía transrotuliana (22,3%) frente a la vía parapatelar medial (12,3%). Con la vía parapatelar aparecieron dos casos de avulsión parcial del tendón rotuliano y un caso de necrosis cutánea. Presentaron molestias femoropatelares 4 pacientes en el abordaje parapatelar medial y 4 casos con la vía transrotuliana. Existió falta de unión de la osteotomía en dos casos y seudoartrosis fibrosa en 3 pacientes. Conclusiones. Existe una disminución de la potencia extensora en el abordaje transrotuliano con menores complicaciones sobre el aparato extensor. Este abordaje podría considerarse en casos especialmente complejos de revisión protésica de rodilla


Purpose. To compare the repercussion of total knee arthroplasty (TKR) on knee extensor strength when performed through a medial parapatellar approach vs. a patellar osteotomy. Materials and methods. This is a retrospective study that included 22 patients. Mean follow-up was 24.6 months and mean age 70.2 years. Results. There is a greater deficit in the knee extensor mechanism when the transpatellar approach is performed (22.3%) vs. the medial parapatellar approach (12.3%). With the parapatellar approach, there were two cases of a partial avulsion of the patellar tendon and one case of skin necrosis. Four patients had patellofemoral discomfort with the medial parapatellar approach and another four with the transpatellar one. There were two cases of non-union of the osteotomy and three cases of fibrous pseudoarthrosis. Conclusions. There is a reduction in knee extensor strength with the transpatellar approach with fewer complications for the extensor mechanism. This approach could be considered in specially complex cases of TKR

ABSTRACT

Objetivo. Estudio del papel actual del enclavado endomedularcon tallos de Ender para el tratamiento de fracturas pertrocantéreas y análisis de sus complicaciones más frecuentes. Material y método. Estudio retrospectivo de 372 fracturas pertrocantéreas tratadas mediante enclavado endomedular de Ender en el período comprendido entre los años 1988 y 1999, analizando parámetros epidemiológicos, radiológicos, así como sus complicaciones más frecuentes. Para la selección de los pacientes del estudio se utilizaron como criterios de exclusión pacientes con fracturas patológicas, fracturas abiertas o edad inferior a 60 años. La edad media obtenida fue de 81 años, con un 64% de los pacientes que precisaban ayuda para la deambulación previamente a la fractura. Se realizó análisis multivariante de los distintos parámetros utilizando el soporte informático SPSS 10.0. Resultados. El tiempo quirúrgico medio fue de 37 minutos, y la necesidad de transfusión fue baja (44,7%). Cincuenta y cinco pacientes precisaron la extracción de los clavos por molestias relacionadas con el implante, aunque tras la retirada de los mismos se detectó persistencia de la clínica en 20 de los 55 casos. La mortalidad en el primer año fue del 20,5%. Conclusiones. Con los datos aportados por el estudio, estimamos que el enclavado endomedular de Ender es una técnica indicada en fracturas pertrocantéreas estables en pacientes con alta comorbilidad y escasa demanda funcional, donde el resultado funcional y la supervivencia para este tipo de pacientes es satisfactorio, con una disminución de los costes hospitalarios


Objective. Study of the current use of Ender intramedullary nails for the treatment of intertrochanteric fractures and analysis of the most frequent complications. Materials and methods. Retrospective study of 372 intertrochantericfractures treated with Ender intramedullary nails in the period from 1988 to 1999. Epidemiologic and radiologic parameters and the most frequent complications were analyzed. Patients were selected using as exclusion criteria pathologic fracture, open fracture, and age under 60 years. The mean age was 81 years and 64% of patients used walking aids before the fracture. A multivariate analysis was made of the different parameters using the SPSS 10.0 program. Results. Mean surgical time was 37 minutes and only 44.7% of patients required blood transfusion. Nails were removed in 55 patients for implant-related discomfort although clinical manifestations persisted after removal in 20 of the 55 patients. The first-year mortality was 20.5%. Conclusions. We conclude that Ender intramedullary nailingis indicated in stable intertrochanteric fractures in patients with a high comorbidity and low functional demand. In such patients, functional results and survival are satisfactory and hospital costs are lower
