本文回顾分析了2003-2007年间接受广泛的半盆骨切除和随后的重建的16例原发恶性骨盆肿瘤患者。患者的平均年龄为27岁，而中位随访时间为36个月(范围23-62个月)。根据术前计算机断层扫描和随后的手术模型，为每个患者单独设计半盆腔假体。假体3年存活率为69%。局部复发3例(19%)，4例死于肺转移。平均随访肌肉骨骼肿瘤学会功能评分为72%。综上所述，计算机辅助定制半骨盆假体可以快速、有效地修复骨盆肿瘤内半盆切除术后的骨缺损。
This is a retrospective analysis of 16 patients with primary malignant pelvic tumors who underwent wide resection of the hemipelvis and consequent reconstruction between 2003 and 2007. Mean patient age was 27 years, whereas median follow-up was 36 months (range, 23-62 months). Hemipelvic prostheses were individually designed for each patient based on preoperative computed tomographic scans and consequent surgical modeling. The 3-year prosthesis survival rate was 69%. There were 3 cases of local recurrence (19%), and 4 patients died because of pulmonary metastases. The mean follow-up Musculoskeletal Tumor Society functional score was 72%. In conclusion, computer-aided custom-made hemipelvic prosthesis can be applied to quickly and effectively restore the bone defect after internal hemipelvectomy for treatment of pelvic tumors.
