一种修复股骨近段骨缺损的新方法

A New Method to Repair Defect of Proximal Femur

本文报道了５例股骨近段良性和恶性肿瘤，年龄２０～３２岁，平均２６．７岁。瘤段切除后骨缺损最长为１６．２ｃｍ，最短１０．８ｃｍ，平均１２．４ｃｍ。均采用冷冻异体骨段移植修复骨缺损、加压钢板内固定、髋关节融合术治疗。经１２～３７个月随访，Ｘ线片显示：无螺钉松动及钢板断裂，其中４例达骨性融合，融合率为８０％。本术式的最佳指征为股骨近段良性或低恶性肿瘤切除后骨缺损的年轻患者。该手术具有内固定牢靠、不需外固定、护理方便和融合率较高等优点。

Five patients suffering from benign and malignant tumor localized in the proximal femur, with ranging from 20 to 32 years of age, were reported. Length of bone defect following resection of proximal femur tumor ranged from 10.8 to 16.2cm,averaged 12.4cm. Defects of proximal femur were reconstructed and repaired by hip arthrodesis using allograft of bone with compression plating. All patients,with a follow-up interval of 12￣37 months, had not X-ray evidence of screw loosening or plate fatigue.Four of these cases had a complete osseous fusion of hip joint. The best indication for this operation was young patient with a major defect of upper part of femur after resecting benign or malignant tumor.The operation had the advantages of rigid internal fixation without postoperative hip spica-cast, nursing the patients conveniently and higher fusion rate, etc.
