Abstract
Purpose. To evaluate the efficacy of revision hip arthroplasty with use of distal fixation revision femoral component.Patients and methods. From June 2004 through October 2015 one hundred thirteen revision arthroplasties were performed in patients with type 3A, 3B and 4 femoral defects by Paprovsky classification. Solution, Wagner SL and Cerafit revision femoral components for distal fixation were used. In the majority of cases (87) the cause of revision intervention was aseptic instability of the femoral component. In 60 cases revision was performed for cementless femoral components, in 53 - for cement components.Results.Follow up period made up from 1 to 12 years. In 83.2% of cases excellent, good and satisfactory treatment results, i.e. pain syndrome remission, restoration of joint movements and extremity weight bearing ability were achieved.Conclusion.Wagner SL, Solution and Cerafit modular revision stems ensure acceptable clinical treatment results and can be the implants of choice for hip femoral component revision arthroplasty in types 3A, 3B and 4 femoral defects by Paprovsky.
