摘　　要：目的探讨微型外固定架治疗掌指骨开放性粉碎骨折的疗效。方法 2009年10月-2011年4月,收治掌指骨开放性粉碎骨折33例。男25例,女8例;年龄21～62岁,平均25.5岁。开放性骨折Gustilo分型:Ⅱ型7例,ⅢA型26例。单纯掌指骨粉碎骨折20例,合并指间或掌指关节骨折13例。肌腱部分或完全断裂18例。伤后至手术时间2～8 h,平均3.7 h。一期清创复位,采用微型外固定架固定骨折。结果术后30例患者切口Ⅰ期愈合,无钉道感染;3例出现切口感染,导致骨不连。2例掌指骨粉碎骨折发生骨不连。33例均获随访,随访时间6个月～1年,平均8个月。X线片示13例术后8周骨折愈合,其中单纯掌指骨粉碎骨折8例,合并关节骨折5例;12例术后12周愈合,其中单纯掌指骨粉碎骨折7例,合并关节骨折5例;3例单纯掌指骨粉碎骨折术后6个月愈合。去除外固定架后经功能锻炼,仍有3例单纯掌指骨粉碎骨折患者及4例合并关节损伤患者残留关节僵硬,未出现手指旋转及对线畸形,无慢性疼痛发生。术后6个月按照手部关节总活动度功能评分,28例骨折愈合者中,优7例,良12例,可5例,差4例,优良率67.9%。结论应用微型外固定架一期治疗掌指骨开放性粉碎骨折固定可靠,骨折愈合率高;波及关节的开放骨折术后功能不佳。Objective To explore the effectiveness of mini external fixation device for comminuted open fractures of the metacarpal and phalange. Methods Between October 2009 and April 2011, 33 patients with comminuted open fractures of the metacarpal and phalange were treated with mini external fixation device. There were 25 males and 8 females, aged from 21 to 62 years with an average of 25.5 years. Of 33 cases, 7 were rated as Gustilo type II and 26 as Gustilo type IIIA; 20 cases were diagnosed as having simple metacarpal and phalangeal comminuted fractures and 13 cases as having combined interphalangeal or metacarpophalangeal joint fractures. Partial or complete rupture of tendon was observed in 18 cases. The time between injury and operation was 2-8 hours （mean, 3.7 hours）. After one stage debridement and reduction, fracture was fixed with mini external fixation device. Results Primary healing of incision was obtained in 30 cases and no pin hole infection was found. Incision infection occurred in 3 cases and leaded to nonunion. Nonunion also occured in 2 cases of simple metacarpal and phalangeal fractures. The mean follow-up was 8 months （range, 6 months to 1 year）. X-ray films showed fracture healing in 13 cases after 8 weeks （8 cases of simple metacarpal and phalangeal fractures and 5 cases of combined interphalangeal or metacarpophalangeal joint fractures）, in 12 cases after 12 weeks （7 cases of simple metacarpal and phalangeal fractures and 5 cases of interphalangeal or metacarpophalangeal joint fractures）, and in 3 cases of simple metacarpal and phalangeal fractures after 6 months. After removing the mini external fixation device and functional exercise, 3 cases of simple metacarpal and phalangeal comminuted fractures and 4 cases of combined interphalangeal or metacarpophalangeal joint fractures still had joint stiffness, but had no finger rotation and alignment deformity or chronic pain. According to the measurement of total active movement for 28 patients who obtained fracture healing, the results
