髋臼周围恶性肿瘤切除后股骨头旷置术的临床应用

目的 探讨髋臼周围恶性肿瘤切除后股骨头旷置术的临床应用.方法 1997年5月至2005年6月共有25例切除后采用股骨头旷置术的髋臼周围恶性肿瘤患者得到随访,其中男性15例,女性10例;年龄16～75岁,平均42岁;骨肉瘤4例,软骨肉瘤12例,尤文肉瘤1例,原始神经外胚层瘤1例,骨髓瘤1例,恶性纤维组织细胞瘤1例,滑膜肉瘤2例,转移性肿瘤3例.根据Enneking骨盆肿瘤分区:肿瘤累及Ⅰ、Ⅱ区12例;Ⅰ、Ⅱ、Ⅲ区5例;Ⅱ、Ⅲ区4例;Ⅱ区2例;Ⅰ、Ⅱ、Ⅳ区2例.共有7例行新辅助化疗,5例行单纯术后辅助化疗,4例行术后放疗.髋臼周围切除后,采用股骨头旷置术,术后皮牵引6～8周,牵引质量2～3 kg.以后扶拐逐渐步行活动.结果 25例股骨头旷置术中6例出现手术后并发症(24.0%).随访时间3～10年,11例由于肺转移或远处转移并发肺转移死亡;2例带瘤生存;12例无瘤生存.术后5年及10年生存率分别为60%和54%.股骨头旷置术后肢体短缩在2.5～7.5 cm,平均5 cm.本组病例术后功能评价根据Enneking1993MSTS评分系统进行,平均术后功能评分是17分(12～19分).术后3个月后,患者基本能够正常坐,扶单拐跛行,能自主上下楼梯,去拐后也能跛行行走.结论 累及髋臼周围的恶性肿瘤,切除后股骨头旷置术是一种可选择的重建方式,能取得相对满意的临床效果.髋臼周围高度恶性肿瘤、软组织重建条件不佳、具有感染高危倾向者、经济条件不佳的患者,是股骨头旷置术的适应证.

Abstract：

Objective To discuss the resection pseudoarthrosis for pelvic malignant tumors around acetabular. Methods From May 1997 to June 2005, 25 patients with malignant tumors around acetabular were treated surgically with resection pseudoarthrosis. The series comprised 15 males and 10 females with an average age of 42 years old (range from 16 to 75 years old ) . There were 4 osteosareomas, 12chondrosarcomas, 1 Ewing's sarcoma, 1 neuroectodermal tumor, 1 myeloma, 1 malignant fibrohistiocytoma,2 synovial sarcomas, and 3 metastases. Pseudoarthrosis was performed after resection of pelvic malignant tumors around acetabular. The affected side was protected postoperatively by skin traction with 2-3 kg weight for 6 to 8 weeks. After then, the patients walked gradually with a cane. Results Among 25 patients, 6 had complications(24% ). At a follow-up ranging from 3 to 10 years, 11 patients died of lung metastases, 2relapsed, 12 remained alive free of disease. There was an average crispation of 5 cm( range from 2. 5 to 7.5cm). The patients were functionally evaluated according to Enneking's MSTS criteria in 1993. The average MSTS functional score was 17 points ( 12 to 19 points). After 3 months postoperative, the patients could sit normally, walk with a cane, and even walk limpingly without cane. Conclusions Resection pseudoarthrosis for pelvic malignant tumors around acetabular results in good clinical results at the time of mid-term and long-term follow-up. And pseudoarthrosis is advisable especially for patients with malignant highly tumors around acetabular, poor soft tissue reconstruction condition, high risk for infection, poor economy.
