| 摘 要： | 目的：探讨骨痂延长术治疗儿童股骨干大段病理性骨缺损的临床疗效。方法：对39例股骨化脓性骨髓炎导致的大段病理性骨缺损进行双侧、单侧外固定支架或髓内骨痂延长术，术后延长速度2～2．5cm／m。结果：随访时间13～57月，经临床检查与影像学观察显示所有骨缺损均已愈合；骨延长9～31cm，延长率平均49％；延长段愈合指数为30d／cm，骨不连接处愈合时间平均约134d；无骨髓炎复发及再骨折。结论：骨痂延长术治疗股骨化脓性骨髓炎后大段骨缺损是一种疗效确切、手术简单、适应性强，可动态调节肢体长度，减少肢体畸形的方法。

| Abstract: | Objective To study the clinical efficacy of callotasis for pathological segmental defects in child femur. Methods Thirty-nine patients with segmental femoral defects suffered from suppurative osteomyelitis were treated with the bilateral, unilateral external fixation frame or intramedullary callotasis. The rolongational rate was from 2 to 2.5 cm per month after the operation. Results After a 13 to 57 month follow-up, all cases were healed according to clinical examination and radiological observation. The prolongational length ranged from 9 to 31 centimeters. Average ratio of prolongation reached 49%. The healing index was 30 d/cm, and the healing time of non-union was 134 days. No recurrent suppurative osteomyelitis or fracture was observed. Conclusion Callotasis is a reliable, simple and hyperadaptable method for femural segmental defects. |
