目的:探讨锁骨上神经的游离保护在锁骨骨折切开复位内固定术中的应用及其疗效观察。方法:自2017年9月至2018年10月我们共收治锁骨Robinson Ⅱ型骨折患者63例，其中采用传统手术方式治疗33例，采用术中仔细游离并保护锁骨上神经的手术方式治疗30例。比较两组患者的切口长度、手术时间及术中出血量。于术后2周、6个月、12个月随访，对术区皮肤感觉异常率、异常程度、异常面积等指标进行比较，从而观察疗效。结果:两组患者均顺利完成手术。游离神经保护组手术时间稍长于传统手术组，差异有统计学意义(n P0.05)。术后所有患者手术切口均甲级愈合，骨折达到骨性愈合。术后2周、6个月、12个月随访时，游离神经保护组患者手术切口周围的皮肤感觉异常率、异常程度、异常面积均低于传统手术组，差异有统计学意义(n P<0.05)。n 结论:仔细游离保护锁骨上神经在锁骨骨折切开复位内固定术中具有临床意义，能够减少术后局部皮肤感觉异常的发生可能。“,”Objective:To explore the clinical application and efficacy of the free protection of the supraclavicular nerve in the open reduction and internal fixation of clavicular fractures.Methods:From September 2017 to October 2018, 63 patients with Robinson type Ⅱ clavicular fractures were treated, including 33 patients treated with traditional operation and 30 patients treated with careful dissociation and protection of supraclavicular nerve during operation. The incision length, operation time and intraoperative hemorrhage of the two groups were compared. After 2 weeks, 6 months and 12 months follow-up, the abnormal rate, degree and area of paresthesia were compared to observe the clinical efficacy.Results:The operation was successfully completed in both groups. The operation time of the free nerve protection group was slightly longer than that of the traditional operation group and the difference was statistically significant (n P0.05). After operation, the incision of all the patients healed in Grade A, and the fractures achieved healing. During the follow-up of 2 weeks, 6 months and 12 months after operation, the abnormal rate, degree and area of paresthesia around the incision in the free nerve protection group were lower than those in the traditional operation group, and the differences were statistically significant (n P<0.05).n Conclusion:Careful dissociation and protection of supraclavicular nerve is of clinical significance in open reduction and internal fixation of clavicular fractures, which can reduce the possibility of local paresthesia after operation.
