内锁髓内钉并异体骨植骨治疗肱骨肿瘤切除术后骨缺损

目的：评价肱骨内锁髓内钉复合异体骨段（关节）移植重建肱骨恶性肿瘤所致的大段骨缺损提临床效果。方法：应用肱骨内锁髓内钉复合异体半关节或骨段移植治疗须骨恶性骨肿瘤１１例，随访时间１１￣３８个月。结果：８例植骨愈合，２例骨不连，１例肿瘤局部复发后截肢。术后总评优良率６３．６％。植骨延迟愈合及肩关节无力是主要的并发症。结论：肱骨内锁髓内钉固定牢固，复合异体骨段（关节）移植允许患者早期活动，值得推荐。

Humeral Massive Bone Defecy Reconstruction by Allograft with Interlocked Intramedullary Nailing

Objective: To evaluate the effect of allografting with interlocked intramedullary nailing on humeral massive bone defect reconstruction. Methods: The interlocked intramedullary nailing had been used on 11 patients with humeral malignant tumor by allografting. The range of follow up was 11 to 38 months. Result: 8 of 11 allograft host bone junctions healed and two were non union. 1 tumor local recurrence and the patient suffered amputation. 8 shoulders restoration were limited but functional range of motion and strength and the follows were poor. The rate of excellent and good was 63.6% base on the Mankin's allograft assessment system. Conclusion: Our results suggested this technique can accomplish stable fixation, allow early movement of shoulder joint.
