目的　探讨骨盆肿瘤切除手术入路、手术方法及评估手术疗效。  方法　收集自1992年1月至2008年11月骨盆肿瘤切除术患者46例，分析患者手术入路、手术方式，随访术后功能及并发症。46例中，年龄32~65岁，平均46.8岁；男性27例，女性19例；恶性骨肿瘤34例，侵袭性良性骨肿瘤12例。全部病人行骨盆部分切除术或骶骨部分切除术，Ⅰ区肿瘤（髂骨）采用沿髂嵴切口，Ⅱ区肿瘤（髋臼周围）采用“人”字切口，Ⅲ区（耻骨、坐骨）采用腹股沟+会阴旁切口；Ⅳ区（骶骨）采用前后路联合切口,其中41例肿瘤完整切除，5例肿瘤巨大分块切除，6例患者行肿瘤灭活再植重建骨盆环，4例用大块异体骨块重建骨盆环，3例用自体骨块重建髋臼。21例肿瘤巨大者术前行肿瘤血管栓塞术。恶性肿瘤术后行适当放疗或/和化疗。  结果　病例随访时间3~53月，平均32月，46例中，1例术后3月因局部感染合并内在衰竭死亡，2例术后1年因肺转移死亡，43例存活。存活患者中，按Enneking法评分，35例超过23分，功能优良，5例一般，3例差。功能差的主要原因是肿瘤切除中神经切断或切除范围大引起的。  结论　骨盆肿瘤手术可以取得满意疗效，选择合适的手术入路，完整切除肿瘤，骨盆环重建，尽可能保留重要的神经是手术后取得满意功能的关键。

Objective　To investigate the operative approach and treatment effects of the tumors of pelvic ring.　Methods　From January 1992 to November 2008, 46 patients with tumors in pelvic ring were treated. In all cases, 34 suffered from malignant tumor, and 12 from benign tumor with malignant inclination (27 males and 19 females, aged 32-65 years, averagely 46.8 years). Partial pelvitomy or partial sacrectomy were performed for all cases. The ilioinguinal incision, utilitarian incision, inguinal and perineum incision, and the anterior and posterior approach were used for typeⅠ, Ⅱ, Ⅲ and Ⅳ tumors respectively. The benign and malignant tumors in pubis, ischium or pubic symphysis were resected radically, defects were reconstructed with plastic plate or not.　Results　The following up time was about 3-53 months (averagely 32 months), and 43 patients survived.　Conclusions　Pelvic tumorectomy will get good therapy effects. Radical resection, proper reconstruction according the position of the tumor and carefully protection of the nerve are the key to get good results.
