摘要

目的

探讨采用克氏针阻挡技术、闭合复位固定的方法治疗中节指骨基底部撕脱骨折的临床疗效。

方法

纳入东部战区总医院秦淮医疗区2019年5月至2022年5月收治的7例中节指骨基底部背侧撕脱骨折患者及13例中节指骨基底部掌侧撕脱骨折的患者，采用克氏针阻挡技术、闭合复位固定的手术方法进行治疗。测量患侧及健侧手指总主动活动度（TAM），并进行视觉模拟量表(VAS)评分，复查X射线观察骨折愈合情况及关节面平整度。

结果

术后患者随访时间为6～12个月，平均9个月，无针道感染、皮肤坏死、疼痛及关节炎等表现。术后1～3个月复查X射线提示骨折端获得骨性愈合、关节面平整。术后6～12个月手指TAM评分结果显示：优11例，良8例，中1例；VAS评分：19例0分，1例2分。

结论

采用克氏针阻挡技术、闭合复位固定方法治疗中节指骨基底部撕脱骨折疗效可靠，手术操作简单，并发症少。

Abstract

Objective

To study the outcome of Kirschner-wire extension blocking technique and closed reduction in the treatment of avulsed fracture of the base middle phalanx.

Methods

A total of 7 patients with avulsed fracture of the dorsal base middle phalanx and 13 patients with avulsed fracture of the volar base middle phalanx admitted to Qinhuai Medical Area of the Eastern Theater General Hospital from May 2019 to May 2022 were included， who were treated by Kirschner-wire extension blocking technique and closed reduction. The total active motion （TAM） of the affected and healthy fingers were measured， and visual analogue scale （VAS） score was evaluated. Fracture healing and joint surface flatness were observed by X-ray.

Results

The follow-up period was 6 to 12 months，with an average of 9 months， no pin-track infection， skin necrosis， pain， or arthritis occurred. Reexamination of X-ray after 1 to 3 months of surgery showed that all fracture ends had achieved bone healing and a smooth joint surface. The TAM result after 6 to 12 months of surgery： excellent in 11 cases， good in 8 cases， and moderate in 1 case. VAS score： 0 point in 19 cases， 2 points in 1 case.

Conclusion

Kirschner-wire extension blocking technique and closed reduction is effective for avulsed fracture of the base middle phalanx， with simple surgical operation and few complications.
