摘要
目的探讨伴有远节指骨基底背侧撕脱性骨折的指伸肌腱止点损伤的治疗方法。方法收治伴有远节指骨基底背侧撕脱性骨折的指伸肌腱止点损伤患者24例，其中开放伤性损伤3例，闭合性损伤21例，最大骨折块波及大于1／3关节面。在C臂机直视下，采用双克氏针内固定骨折块和远指间关节。术后4周后拔出克氏针，用指套固定6周，对远指间关节的屈伸活动范围及X线片表现进行评价。结果术后随访时间6—12个月，锤状指畸形消失，术后均无疼痛及感觉障碍；X线正侧位片示撕脱骨折块均已解剖复位并愈合。采用Dargan功能评定：优17例，良6例，可1例。结论双克氏针内固定法治疗合并骨折的指伸肌腱止点损伤效果满意。
Objective To explore the treatment options of mallet finger caused by avulsion fracture of the distal phalanx base and extensor tendon insertion lesion. Methods Twenty-four eases of mallet avulsion fractures of the distal phalanx, including 3 cases of open injury and 21 cases of dosed injury, were treated using the extension block Kirschner wire technique. 1/3 of the arfic^ar surface was involved in the largest fracture fragments. Double K-wires were inserted under C-arm fluoroscope monitoring to fLX the fracture fi＇agment and the distal interphalangcal （DIP） joint. The K-wires were removed after 4 weeks. A finger splint was used for another 6 weeks. The active range of motion of the DIP joint and roentgenogram were evaluated. Results Postoperatively the patients were follow-up for 6 to 12 months. Mallet deformity disappeared. No pain and sensory impairment was observed. Posteroanterior and lateral X-rays showed anatomical reduction and union of the avulsed fracture fragment. According to Dargan functional evaluation criteria, the outcomes were excellent in 17 cases, good in 6 cases and fair in 1 case. Conclusion This technique leads to satisfactory results and should be considered for treatment of mallet finger caused by extensor tendon insertion lesion and avulsion fracture.
