锁骨骨折内固定术后骨不连临床分析

Clinical Analysis of Nonunion After Internal Fixation of Clavicular Fracture

目的对锁骨骨折内固定术后骨不连的情况进行临床分析。方法选取我院2012年4月—2014年4月收治的160例锁骨骨折患者作为研究对象,将其随机分为对照组和观察组。两组患者均接受手术治疗,观察组患者使用钢板内固定术,对照组患者使用克氏针内固定术,对两组患者术后出现骨不连的情况进行统计和分析,并对其进行6~12个月的随访。结果对照组患者中共有8例发生骨不连,骨不连发生率为10.0%。观察组患者中共有2例发生骨不连,骨不连发生率为2.5%,差异具有统计学意义(P<0.05)。所有骨不连患者均为粉碎性骨折和萎缩型骨不连,骨不连原因为骨折周围出现血运供应障碍。结论粉碎性骨折容易发生骨不连,使用钢板固定术的患者比使用克氏针内固定术的患者发生骨不连的几率低。

Objective To analyze the clinical manifestation of clavicle fracture nonunion after internal fixation of the clavicle. Methods 160 cases in our hospital from April 2012 to April 2014 were fracture patients were randomly divided into control group and observation group. Two patientsunderwent surgical treatment, to observe the use of plate fixation group, control patients using Kirschner wire fixation, statistics and analysis of the situation of nonunion occurred after operation in the two groups, and were followed up for 6~12 months. Results The patients in the control group there were 8 cases of nonunion, bone nonunion rate for 10.0%. Patients in the observation group were 2 cases of bone nonunion, bone nonunion rate was 2.5%, the difference was statistically significant（P〈0.05）. All the patients with nonunion were comminuted fracture and atrophic nonunion, bone nonunion fracture around the blood supply disorder. Conclusion Comminuted fracture prone to nonunion. With plate fixation than patients using Kirschner wire fixation in patients with bone nonunion rate is low.
