Full circumferential bone loss of the proximal femur can be managed by segmental allografts. The use of these grafts is indicated for uncontained defects longer than five cm in length. The femoral implant is cemented into the allograft but not into the host. The allograft host junction is stabilized by a step cut or oblique osteotomy and autografted with residual host femur. The results at five and nine years support this kind of reconstruction as a good alternative for this difficult problem.
股骨近端全周骨缺损可通过节段性同种异体骨移植进行处理。对于长度超过5厘米的非包容性骨缺损，可使用这些移植骨。股骨植入物用骨水泥固定在同种异体骨上，而不是固定在宿主骨上。通过阶梯状截骨或斜行截骨术稳定同种异体骨与宿主骨的结合处，并用宿主股骨残端进行自体骨移植。5年和9年的结果支持这种重建方式是解决这一难题的良好选择。
