After excision of the hemipelvis through a combined subnatal and anterior incision preserving the lower extremity, five patients with periacetabular chondrosarcoma, after a follow-up of three to six years, were able to walk with no support or with minimum lateral support and had resumed their preoperative occupations. None had either the instability that might have been anticipated or incapacitating discomfort from the neoarthrosis, and there was no evidence of spread or recurrence of tumor in any of the five patients. The procedure, which has the same basic indications as a hindquarter amputation, is a rewarding substitute for that mutilating operation, although the follow-up is too short and the series is too small to warrant conclusions as to the cure rate.
通过联合经骶骨和前路切口切除半骨盆并保留下肢后，5例髋臼周围软骨肉瘤患者经过3至6年的随访，能够在无支撑或仅需最小程度的侧向支撑下行走，并已恢复术前工作。5例患者均未出现预期的不稳定情况，也没有因假关节而导致的致残性不适，且无任何肿瘤扩散或复发的迹象。该手术与后肢截肢术具有相同的基本适应证，是一种替代这种致残性手术的有效方法，尽管随访时间过短且病例数过少，无法得出关于治愈率的结论。
