Abstract:

目的:探讨骨又生(DDM)移植结合钢板内固定治疗上肢骨不连的临床疗效。方法:对43例2005年8月至2014年11月间上肢骨不连进行回顾性分析,其中男35例,女8例;10-53岁,平均32.5岁。骨不连部位:锁骨骨不连4例,肱骨近端骨不连5例,肱骨干骨不连16例,尺、桡骨骨不连6例,桡骨骨不连4例,指骨骨不连6例。39例患者行切开复位内固定,4例患者行外固定保守治疗。病程为5个月到3年,平均1.1年。38例患者行骨又生植骨,5例行骨又生联合同种异体骨植骨。结果:43例患者中2例失访。41例随访19-54个月,平均32.6个月。所有患者术后均达骨性愈合,愈合时间为3-6个月,平均4.5个月。锁骨骨不连优良率100%,肱骨近端骨不连优良率87.5%,肱骨干骨不连优良率80%,尺、桡骨骨不连优良率83.3%,桡骨骨不连优良率100%,指骨骨不连优良率75%。结论:骨又生具有促进骨组织再生和骨折愈合的作用,对减轻病人痛苦、减少医疗费用、提高患者生活质量具有重要的临床意义
