目的：比较AO 微型钢板与克氏针内固定在断指再植术中的临床应用效果。方法：断指患者52 例，其中26 例(34 指)断指采用AO 微型钢板内固定治疗(观察组)，另26 例(37 指)采用克氏针交叉固定治疗(对照组)，术后均辅以功能康复训练。比较两组患者的手术时间、骨折愈合时间及断指功能恢复优良率。结果：观察组与对照组断指再植平均耗时分别为(83.5±10.2) min、(62.7± 8.3) min (P<0.01)，骨折愈合时间分别为(5.8±0.9)周、(8.4±1.7)周(P<0.01)，断指功能恢复优良率分别为91.2%、62.2%(P<0.01)。结论：在断指再植术中应用AO 微型钢板内固定与克氏针比较，虽手术耗时较长，但骨折愈合时间短，断指功能恢复优良，值得临床推广应用。

英文摘要:

Objective: To compare the effect of AO mini-plate and Kirschner wire fixation in digital replantation surgery. Methods: 52 patients with severed fingers were selected. 26 cases (34 fingers) were treated with AO mini-plate fixation (observation group), and the other 26 patients (37 fingers) with Kirschner wire cross fixation (control group). Postoperative functions were supplemented by rehabilitation training. Operating time, healing time and finger fracture function of the two groups were compared. Results: The average replantation surgery time of the observation group and control group were (83.5±10.2) min and (62.7±8.3) min (P<0.01), respectively. Fracture healing time were (5.8±0.9) weeks and (8.4±1.7) weeks (P<0.01), respectively. Excellent rate of finger function were 91.2%, 62.2% (P<0.01), respectively. Conclusion: Compared with Kirschner wire in the application of finger replantation, although AO mini-plate fixation in the surgery takes longer, the healing time is short, and functional recovery of finger is fine, which is worthy of clinical application.
