Conservative hemipelvectomy is the resection of the ischium, ilium and subjacent extremity. It differs from the orthodox hemipelvectomy method by retaining the ilium, which permits the patient to have normal balance, Sarcomas of the soft tissue extend toward the attachment of the pelvis. The operation has been performed upon ten patients, and the entire operative procedure can be done using the anterior approach, thus minimizing the need to turn the patient. This technique is less traumatic than either disarticulation of the hip joint or hemipelvectomy and can be performed in approximately one and one-half hours, blood loss being limited to an amount varying from 500 milliliters to 1 liter. No postoperative deaths have been recorded. Of the ten patients operated upon, none have had a local recurrence. One obese elderly woman with a liposarcoma died two years after operation from diffuse metastases. The other nine patients are alive and well from two to six years after amputation. The balance of these patients is manifested by the fact that two of them are excellent amputee-skiers.
保守性半骨盆切除术是指切除坐骨、髂骨及相邻肢体。它与传统的半骨盆切除术方法不同之处在于保留了髂骨，这使得患者能够保持正常平衡。软组织肉瘤会向骨盆附着处延伸。该手术已在10例患者身上实施，整个手术过程可采用前路入路完成，从而最大限度地减少患者翻身的需求。与髋关节离断术或半骨盆切除术相比，这种技术的创伤较小，大约可在一个半小时内完成，失血量限制在500毫升至1升之间。术后无死亡记录。在接受手术的10例患者中，无一例出现局部复发。一名患有脂肪肉瘤的肥胖老年女性术后两年因弥漫性转移死亡。其他9例患者在截肢后两到六年存活且状况良好。其中两名患者成为优秀的截肢滑雪运动员，这体现了这些患者的平衡能力。
