Prognostic study, Level II (retrospective study).

This series contributes to a better characterization of a rare pathology demonstrating that both surgical and endovascular treatment can be performed with very low morbidity and mortality.

Resumen. El presente artículo aborda la construcción del Índice de Rentabilidad Social en Comunicación (IRSCOM), que pretende recoger valores ligados al funcionamiento de los medios audiovisuales, eludiendo la visión mercantilista, potenciando la participación ciudadana y la transparencia en su gestión. Este indicador es una propuesta que persigue corregir las deficiencias en la rentabilidad social de los medios para consolidar modelos mediáticos que respondan a lógicas centradas en la construcción democrática, la fortaleza de la pluralidad y la diversidad.

Background:There are concerns with regard to the femoral fixation in cementless total hip arthroplasty in elderly patients. We report a retrospective analysis of clinical and radiological results of uncemented metaphyseal fit modular stem in elderly patients irrespective of anatomic characterstics of proximal femur.Materials and Methods:This study reviews the outcomes of 60 primary hip replacements using a metaphyseal fit modular stem (third-generation Omniflex stem) conducted in 54 patients, of age 75 years or older. After a mean follow-up of 10,4 years, complete clinical and radiographic records were available for 52 hips of 48 patients. The patients were evaluated by Harris Hip Score (HHS).Results:There was a significantly improved pain score and Harris Hip Score (41,6 to 83,2). Six stems (11.53%) were revised: four because of periprosthetic fracture; one stem was well fixed, but presented a large osteolytic lesion in the metaphyseal area and the last stem was revised because of aseptic loosening. Stem survival taking aseptic loosening as the end-point was 98%. Bone atrophy in the proximal femur caused by stress shielding was observed in 39 stems (75%), but there was no case of subtrochanteric stress shielding. Moreover, atrophy appeared within two years postoperatively, with no extension thereafter.Conclusions:We achieved good clinical and radiographic results by uncemented metaphyseal fit femoral stem regardless of patient's age and femoral canal type.
