Exchange impaction allografting for femoral revision hip arthroplasty: Results in 87 cases after 3.6 years’ follow-up

A total of 87 femoral exchange revision procedures were performed in 80 patients. Mean follow-up time was 3.6 years. Patients were followed prospectively. At follow-up, 5 patients had died, and 74 (93 %) completed follow-up. Results were evaluated on the basis of incidence of rerevisions and other complications, patient satisfaction, and preoperative and postoperative Harris hip score. Radiographic evaluation included preoperative femoral bone status evaluated according to Endo-Klinik and Mallory, incidence of subsidence, bone–graft incorporation, and signs of loosening. Three patients were rerevised, 2 patients suffered postoperative femoral fractures, 5 patients had hip dislocations, and 1 patient suffered deep infection. Of patients, 90% expressed satisfaction with the result. Harris hip score improved from 39 to 82 (P <.001). Radiographically, only 2 patients showed subsidence of >5 mm. Of patients, 88% showed signs of graft incorporation, and only 1 patient showed signs of loosening. Intermediate follow-up evaluation of the exchange femoral revision technique showed good clinical and radiographic results. With a rerevision rate of 3.5% and incidence of >5 mm subsidence of 2.5%, we did not observe the problems of subsidence and femoral fractures that previous studies have described.
