Abstract:
Objective To evaluate the effects of Burch-Schneider(BS) acetabular reinforcement ring applied in primary or revision total hip arthroplasties in 9 patients with combined or cavitary acetabular bone defects. Methods A retrospective follow up that averaged 3.8 years was performed with a special scoring system comprising the patients symptoms, signs and function. Results The excellent and good function were achieved in 89% of all cases. Conclusion 1)BS reinforcement ring could be effectively and reliably applied in primary or revision total hip arthroplasty or in patients with severe acetabular bone defects. 2)BS reinforcement ring shows the biological fixation feature, so as to provide good foundation for long-term satisfactory function of hip. 3)The lower ear of BS ring need not to be fixed to ischium with screws as usual, but be inserted in obturator foramen above transverse ligament, thus imparting some elastic resilience to it. 4)The upper ear should be folded through such a curve that its curvature was in compliance with that of ilium, which would be better performed in one session. 5)The appropriate amount of 0.8 cm?0.8 cm?0.8 cm morcellized allografting bone was used to snugly fill the space, which would be conducive to desirable incorporation between prosthesis and bone, and the authors propose that the patients should be allowed weight-bearing earlier.
