[Realloplasty of the acetabular component of the hip joint endoprosthesis without mechanical support systems]

This work presents the tactics of surgical procedures in 40 patients who underwent revision of the hip joint due to isolated loosening of the acetabular component of the endoprosthesis. The studied group were operated between 2004 to 2006 without the use of mechanical support systems. Realloplasty of the acetabular component involved the evaluation of: etiology of acetabular loosening, concomitant diseases in the operated patients, and the grade of acetabular defects according to Paprosky's classification. In this work we analyze the type of both the loosened acetabulum and that used in revision, and discuss complications. Finally, we present a clinical evaluation of the operated patients according to Harris scale before revision surgery and six and twelve months after, with good early results.
