锁定钢板内固定治疗长骨骨折术后非感染性骨不连

目的 探讨长骨骨折术后骨不连的病因,总结锁定钢板内固定结合自体骨移植治疗四肢长骨非感染性骨不连的经验.方法 总结2006年8月-2010年8月应用锁定钢板内固定治疗并获得完整随访的38例骨不连患者.结果 随访时间6～24个月,平均12个月；骨折在3～7个月内牢固连接,平均愈合时间5.3个月,无内置物松动、断裂等并发症.结论 医源性因素是骨折切开复位内固定术后骨不连的主要原因,锁定钢板内固定结合植骨术是治疗四肢长骨非感染性骨不连的有效方法.

Treatment of non-infective nonunion with locking plates following surgery for long bone fractures

Objective To investigate the cause of fracture nonunion and discuss the experience of locking plates fixation combined with autoallergic cancellous bone in the management of non-infective long bone nonunion.Methods A retrospective analysis was made in 38 patients(29 males and 9 females)with fracture nonunion treated with locking plates fixation combined with autoallergic cancellous bone from August 2006 to August 2010.Of all,22 patients were treated with plates and 16 with interlocking intramedullary nails.Results All the patients were followed up for a mean of 12 months(range,6-24 months).The bone union time for all the fractures averaged 5.3 months(range,3-7 months),with no complications like implant loosening or fracture.Conclusions Iatrogenic factor is the main cause for fracture nonunion after open reduction and internal fixation of long bone fractures and the locking plates combined with autoallergic cancellous bone are a safe and effective treatment procedure.
