目的探讨髋臼周围肿瘤切除与重建的方式及合并症。方法回顾分析1997年7月至2003年7月髋臼部位原发肿瘤患者行肿瘤切除重建手术的临床资料。31例患者中,男性19例,女性12例,年龄12～78岁,平均年龄37岁。其中,软骨肉瘤12例、尤文瘤1例、骨肉瘤3例、淋巴瘤1例、癌肉瘤1例、恶性纤维组织细胞瘤1例、骨髓瘤2例、骨巨细胞瘤9例、动脉瘤样骨囊肿1例。21例患者行髋臼切除、骨盆重建,其中人工半骨盆8例、马鞍式关节7例、灭活再植+人工髋关节置换6例。10例患者行肿瘤刮除+骨水泥填充+人工髋关节置换。结果21例行Ⅱ区肿瘤切除、髋臼重建的患者中,5例出现局部复发,其中3例为行半骨盆灭活再植的患者。3例骨肉瘤中2例死亡;12例软骨肉瘤患者中,随访9人,6例无瘤生存。术后2个月后,21例患者能够正常坐、扶单拐行走。结论髋臼区域的肿瘤切除后可行异体或人工半骨盆移植进行修复,或将瘤段骨壳灭活再植进行重建。髋臼周围肿瘤切除重建的过程中应注意(1)广泛切除肿瘤;(2)熟悉各种髋臼重建方法的优缺点,防止合并症的发生;(3)髋臼重建后的稳定性较差,应注意站立时在健侧拄一手杖,保护再造髋关节;(4)预防皮缘坏死及伤口感染,骨盆肿瘤切除容易发生伤口问题。 Objective To investigate the methods and complications of resection and reconstruction of tumors around the acetabulum. Methods The clinical data of patients undergoing resection and resection of the tumor from July 1997 to July 2003 with primary acetabulum were retrospectively analyzed. Among the 31 patients, 19 were males and 12 were females, aged from 12 to 78 years with a mean age of 37 years. Among them, chondrosarcoma in 12 cases, Ewing’s tumor in 1 case, osteosarcoma in 3 cases, lymphoma in 1 case, carcinosarcoma in 1 case, malignant fibrous histiocytoma in 1 case, myeloma in 2 cases, giant cell tumor in 9 cases, Bone cyst in 1 case. Twenty-one patients underwent acetabular resection and pelvic reconstruction, of which 8 were artificial pelvis, 7 were saddle-type joint, 6 were replanted by replantation and artificial hip replacement. Ten patients underwent tumor scraping + bone cement filling + artificial hip replacement. Results Twenty-one patients undergoing resection of the tumor in region Ⅱ and partial reconstruction of the acetabulum had local recurrence in 5 patients, of whom 3 were undergone semi-pelvic inactivation. Two of three osteosarcoma died; 12 of 12 patients with chondrosarcoma were followed up for 9 years and 6 had no tumor. Two months after the operation, 21 patients were able to sit properly and walk around the boarding procedure. Conclusion Allograft or artificial pelvis transplantation can be performed after resection of the tumor in the acetabular region, or reconstruction of the tumor can be reconstructed with inactivation of the bone shell. (1) wide excision of the tumor; (2) familiarity with the advantages and disadvantages of various acetabular reconstruction methods to prevent the occurrence of complications; (3) the stability of the acetabulum after reconstruction is poor , Should pay attention to stand in the healthy side of Zhu Zhu a stick to protect the reconstruction of the hip; (4) prevention of skin necrosis and wound infection, pelvic tumor resection prone to wound problems.
