Twelve adult patients with pelvic sarcoma had implantation of a hemipelvic prosthesis. Eight patients had hemipelvic resection, and four patients had acetabulopubic resection. The implanted prosthesis was a special Vitallium prosthesis, which was specially designed for each patient with the aid of a computer. At a median followup of 57 months, eight patients were free of disease. In four patients with local relapse, two had additional resection, one had hindquarter amputation, and one was observed. In three patients with deep infection, the prosthesis was removed; however, one patient had hindquarter amputation. One patient had dislocation of the hip and prosthesis loosening. Overall survival of patients was 70%, and the survival of prostheses was 42%. In eight patients, the functional evaluation showed that the average functional score with the prosthesis was 11.6 (39%) and without the prosthesis the functional score was 7.0 (23%). Implantation of a megaprosthesis seems to indicate a high complication rate and a poor functional result after hemipelvic resection.
12例成年骨盆肉瘤患者植入了半骨盆假体。8例患者接受了半骨盆切除术，4例患者接受了髋臼耻骨切除术。植入的假体是一种特殊的维他灵假体，借助计算机为每位患者专门设计。中位随访57个月时，8例患者无疾病复发。4例局部复发患者中，2例再次接受了手术切除，1例行后半侧截肢术，1例进行观察。3例深部感染患者取出了假体；然而，1例患者接受了后半侧截肢术。1例患者出现髋关节脱位和假体松动。患者的总生存率为70%，假体生存率为42%。8例患者的功能评估显示，使用假体时平均功能评分为11.6（39%），不使用假体时功能评分为7.0（23%）。半骨盆切除术后植入大型假体似乎表明并发症发生率高且功能结果差。
