Standard Acetabular Component or Antiprotrusion Consolidating Design?

The purpose of the study was determination of optimum technique for acetabular component revision depending on the volume of bone tissue deficit. Between 1992 and 2012 a total number of 843 partial or total revision hip replacement surgeries were performed. In 664 cases the indication for revision surgery was instability of acetabular component. Depending on the design of implant used (polyethylene cement cups, consolidating constructions, cementless cups) all patients were divided into 3 groups. Subsequently each group was divided into subgroups depending on the acetabular defect degree (by Paporsky classification). It was shown that for provision of maximum implant surveillance and reduction of the risk of most common operative complications the early clinical and radiologic detection of developing acetabular instability and revision performance was essential. In cases of delayed revision operation and significant bone tissue deficit it is reasonable to perform revision surgery using consolidating construction with additional bone defect plasty.
