Objective To evaluate the clinical effect of customized artificial prosthesis replacement for treatment of proximal femur tumor. Methods 30 patients with proximal femur tumor had been treated with en block excision and reconstruction with customized artificial prosthesis. The type of the prostheses was as follow: 21 long stem femoral head, 9 total hip prosthesis. The functional outcomes were evaluated according to Musculoskeletal Tumor Society 93 ( MSTS 93 ) score in 6 months after surgery. Results According to the follow-up for 12 to 36 months, 30 patients had no complication with infection, loosening and dislocation of the prosthesis, and fracture around the prosthesis. The mean MSTS 93 score was ( 26. 0 ±2. 14 ), with an excellent limb function in 15 patients, good in 12 patients, and fair in 3 patients. The overall excellent and good function was obtained in 90% of the patients. 2 patients had died in 13 months and in 15 months after surgery. Conclusions Customized artificial prosthesis replacement is an effective method for treatment of proximal femur tumor. It also can obtain good postoperative function.%目的 评价定制人工假体置换治疗股骨近端骨肿瘤的疗效.方法 对股骨近端骨肿瘤30例行瘤段切除、定制人工假体置换治疗.其中21例行加长柄双动性股骨头置换,9例行加长柄全髋置换.术后6个月功能评价采用MSTS 93评分.结果 30例均获随访,时间12～36个月.无感染、假体松动、假体脱位、假体周围骨折等并发症发生.术后6个月MSTS 93评分平均为(26.0±2.14)分;肢体功能:优15例,良12例,中3例,优良率为90%.2例于术后13、15个月死亡.结论 定制人工假体置换是治疗股骨近端骨肿瘤的有效方法,术后髋关节功能良好.
