目的 探讨应用微型外固定器治疗手掌指骨骨折的方法及疗效。方法 对28例手掌指骨骨折应用微型外固定器治疗。结果 术后随访5个月～1年，平均8个月，25例达到解剖复位，2例对位稍差，1例对位欠佳。25例愈合顺利，3例愈合延迟。按ATM法评价术后手指活动度，本组优17例，良9例，可1例，差1例。优良率达92．86％。结论 微型外固定器治疗手部掌指骨骨折创伤小，固定可靠，愈合率高，利于早期功能锻炼，有良好的治疗效果。

Objective To report the method and effectiveness of micro - external fixator treating metacarpal and phalangeal fractures. Methods Twenty- eight cases of metacarpal and phalangeal fractures were treated with micro - external fixator. Results ALL patients were followed up for 5 12 months （average 8 months）. Twenty- five cases obtained anatomic reduction,2 cases reached imperfect reduction and 1 case was below the mark. Twenty - five fractures healed successfully, and 3 had delayed union of fractures. Finger＇ activity was estimated according to ATM standard：excellent 17 cases, good 9 cases, common 1 case, poor 1 case, the overall good - excellent rate of joint function was 92.86 %. Conclusion The micro- external fixator system is an alternative method for the metacarpal and phalangeal fractures with the benefits of limited invasion, excellent fixation, high union rate, earlier functional exercise and satisfactory effect.
