回顾性分析武汉大学人民医院1999-03/2005-05收治的26例髋部原发肿瘤行特制人工假体置换患者的临床资料。所有诊断均经病理组织学证实,软骨肉瘤3例,骨肉瘤6例,滑膜肉瘤1例,骨巨细胞瘤14例,动脉瘤样骨囊肿2例。假体类型:特制全髋关节假体17例,特制人工双极股骨头7例,马鞍式关节假体2例。随访18个月～6年,平均4年3个月。其中10例恶性肿瘤患者局部复发率为40%,保肢率为60%;16例中间性及低度恶性肿瘤患者复发率为12.5%,保肢率为87.5%。肢体功能Enneking评分平均19分,优良率为76.9%。提示特制人工髋关节假体可以有效保持患肢的肢体功能,是髋部肿瘤较为满意的保肢治疗方法之一。
The clinical data of 26 patients with hip primary tumor who underwent artificial prosthesis replacement at Wuhan University People’s Hospital from March 1999 to May 2005 were retrospectively analyzed. All diagnoses were confirmed by histopathology. There were 3 cases of chondrosarcoma, 6 cases of osteosarcoma, 1 case of synovial sarcoma, 14 cases of giant cell tumor of bone and 2 cases of aneurysmal bone cyst. Prosthesis type: special total hip prosthesis in 17 cases, special artificial bipolar femoral head in 7 cases, 2 cases of saddle joint prosthesis. Follow-up 18 months to 6 years, an average of 4 years and 3 months. The local recurrence rate was 40% and the limb salvage rate was 60% in 10 cases of malignant tumors. The recurrence rate was 12.5% in 16 cases of intermediate and low grade malignant tumors, and the salvage rate was 87.5%. The limb function Enneking score averaged 19 points, excellent and good rate was 76.9%. Tip of special artificial hip prosthesis can effectively maintain limb limb function, hip surgery is more satisfied with one of the limb salvage therapy.
