Abstract
Purpose : The aim of this study was to see the results of total hip arthroplasty revision using Wagner femoral revision stem. Materials and Methods : From January 1994 and December 1998, we implanted to twenty-three Wagner revision stems in 22 patient (23 cases). The patients’average age was 54 years and the average follow-up time was 48 months. The causes of the revision were as follows: aseptic loosening (18 cases), periprosthetic fractures with loosening (4 cases), and septic loosening (1 case). Results : The preoperative Harris hip score was 47 points, and this improved to 90.5 points postoperatively. There were 3 cases of inguinal pain, 2 cases of thigh pain, 3 cases of leg length discrepancy, and one case of subsidence of stem exceeding more than 5 mm. Postoperative complications included 2 cases of hip posterior dislocation, and 2 cases of heterotopic ossification. Conclusion : No patient required re-revision surgery to treat stem loosening or other problems. The results of the operations were excellent. However, we had difficulty selecting the optimal stem size with respect to preventing subsidence problems.
