影响重度腕管综合征术后捏力恢复因素的临床分析

Factors influencing the recovery of pinch strength： an analysis in patients with severe carpal tunnel syndrome

目的 探讨影响重度腕管综合征术后指尖型、指侧型和指头型三种捏力恢复的因素.方法 从2009年5月至2011年6月,我们采用腕管切开减压术治疗重度腕管综合征24例,随访21例.术后随访时间为10～ 42个月,对指尖型、指侧型和指头型三种捏力进行测量,将结果与健侧捏力、术后恢复时间、患侧握力、患侧触觉恢复程度等因素进行相关性分析.结果 患者术后患侧与健侧三种捏力比较差异有统计学意义;术后捏力恢复与握力呈正相关;与术后恢复时间、触觉恢复程度无关.结论 重度腕管综合征切开减压术后患侧三种捏力均比健侧差,术后捏力恢复与握力有相关性.

Objective To analyze the factors that influence the postoperative recovery of palmar pinch,key pinch,and tip pinch forces in patients with severe carpal tunnel syndrome.Methods From May 2009 to June 2011,24 patients with severe carpal tunnel syndrome were treated with carpal tunnel release.Among them 21 were follow-up for 10 to 42 months postoperatively.Forces of tip pinch,key pinch and palmar pinch were measured.Correlation analysis was conducted to assess the relationship between pinch force and postoperative recovery time,grip strength and touch sensation recovery of the affected side.Results There were significant differences between pinch forces of the affected side and the contralateral side.Postoperative pinch strength and grip strength were positively correlated.Pinch force was not related to postoperative recovery time and touch sensation recovery.Conclusion Forces of three types of pinch were significantly lower than those of the contralateral side in patients with severe carpal tunnel syndrome who undergo carpal tunnel release surgery.Postoperative pinch strength recovery is related to grip strength.
