自锁髓内钉治疗肱骨干骨折

Treatment of humeral shaft fracture with self - locking intramedullary nail

目的探讨自锁髓内钉治疗肱骨干骨折的方法及疗效。方法采用自锁髓内钉内固定治疗成人新鲜肱骨干骨折，辅以可吸收线或钢丝固定蝶形骨片，同时探查桡神经。结果48例患者骨折全部愈合，骨折愈合时间为4～10个月，平均8个月。除1例由于钉尾过长、2例活动过晚，肩关节功能部分受限外，其余肩肘关节功能均恢复良好。钉尾过长患者，取出髓内钉后，关节功能恢复正常。除1例因牵拉过重致桡神经-过性麻痹外，其余无医源性桡神经损伤。结论应用自锁髓内钉治疗肱骨干骨折．固定牢固、创伤小、骨折愈合快、关节功能恢复好、操作简单、取出方便，具有微创外科的理念，避免X线辐射和医源性神经、血管损伤。

Objective To explore the treatment of humeral shaft frature with self - locking intramedullary nail and efficacy. Methods To use self - locking intramedullary nail to treat fresh humeral shaft fractures, and fixed the butterfly bone chip with absorbed line or wire,at the same time ,radial nerve exploration. Results All 48 cases of patients with fractures healed with healing time of 4 - 10 months, an average of 8 months. In addition to 1 case because the nail tail excessively is long, 2 cases moves too late, the shoulder joint functions were some limited, other shoulder elbow joint functions restored well ,nail in the case with long tail ,the joint function returned to normal after removing the nail. In addition to the 1 case as a result of traction caused by heavy radial nerve palsy had, the others had no nervus radialis medicine source nervus radialis damage. Conclusion In the application the treatment of humeral shaft fracture with self - locking intramedullary nail is simple and avoids exposure to X - ray, the medical source nerve and the blood vessel damage,firmly fixed trauma, the wound is small, the fracture heals quickly, takes out easy, with the concept of minimally invasive surgery.
