[Treatment of bone defect in hip revision].
To investigate the option of treatments for bone defect in femoral revision after total hip replacement (THR), 29 patients (29 hips) who had undergone hip replacement 13.7 years previously were hospitalized again to undergo revisions. 3 patients were given cement protheses and the other 24 patients were given non-cement protheses. In 3 cases were used Synergy+Reflection protheses, and in the others were used CLS +ALLOFIT. All of the patients have got primary healing without early infection symptoms post-operatively. We have been following up 25 cases (25 hips) for 58 months averagely. All the hip joints functioned well. Harris score increased from preoperative 36.8 to postoperative 93.2. In our experience, if there exist significant bone defect in acetabular bone and the coverage of the cup by the graft is more than 80%, bone graft is not needful. If the coverage is between 50% and 80%, bone grains combining bone segment grafts are needful. If the coverage is less than 50%, bone segment grafts be likely to give good effect. In summary, compacted bone grains grafts combining allograft osintegumentale plate could gain satisfactory outcome for femoral bone defect.
