title: [Hip revision arthroplasty in massive bone loss of acetabulum with the use of reinforcement ring].
abstract: The aim of the study was the assessment of results after acetabular revision arthtoplasty with the use of reinforcement ring ReconShell (BBrown - Aesculap) and homogenous bone grafts. There were 49 patients in the study (42 women and 7 men) in the age from 30 to 88 years. The follow-up period ranged from 4 to 48 months. Before operation the mean Harris hip score was 31.14 and at last follow-up 71.64 points. Aseptic loosening of reconstruction ring was found in 3 patients. During next revision good integration of bone grafts, that were implanted into acetabulum at previous operation was found. In one hip revision of loose polietylen cup was performed. Three patient had early dislocation of hip endoprothesis, that were treated successfully in abduction casts. Next 2 patients had re-revision performed for recurrent dislocations. One patient had implants removal for septic loosening. Prolonged wound healing was noticed in 5 patients. Two patients had temporary and one permanent common peroneal nerve palsy. Two patients had temporary femoral nerve palsy. The use of reconstruction rings in massive bone loss of the acetabulum after cup loosening gives satisfactory clinical results. After the procedure patients have stabile joint that allows for weight bearing. Despite relatively high number of complications (most of which are temporary) this procedure is worth recommending.
