为探索行之有效的截骨延长手术方法，总结了5例保留骨膜及松质骨应用外固定架的防骨延长术。结果表明前臂延长，均在延长过程中形成絮状骨化，较常规截骨延长术形成骨化早。5例患者延长4～7cm，80d内完成，全部病例无神经、血管损伤，无患肢水肿、骨延迟连接等并发症，随访1～4年，患肢肩、肘关节功能正常，感觉、肌力、血循环无异常，无畸形愈合。

If the nutrient artery and the periosteum are retained, nutrition of bone issafeguarded after osteotomy' Five patients with pectoral limb lengthening were found to have ear1ier ossificationthan common osteotomy lengthening. One of their upper limbs lengthened 4 to 7 cm during 80 days. None ofthem had complications such as damage of vessels and nerves, edema of limb and tardive synosteosis of bone, etc.They were visited after operation 1 to 4 years, and their limb lengthened was found to have normal functions.
