无头加压空心螺钉治疗第5跖骨基底部撕脱性骨折疗效观察

摘要

目的：探讨无头加压空心螺钉治疗第5跖骨基底部撕脱性骨折的疗效。方法2008年1月至2011年1月，采用切开复位无头加压空心螺钉固定治疗37例第5跖骨基底部撕脱性骨折患者。术后随访时行 X 线片检查评估骨折愈合时间及采用美国足踝外科协会（AOFAS）中前足评分标准评估足部功能恢复情况。结果37例患者随访10～24个月，平均13个月。 X 线片提示骨性愈合时间为术后6～12周，平均8．1周。1例开放性骨折患者出现伤口浅层感染，经治疗后伤口愈合。术后 AOFAS 评分为86～100分，平均94．5分。结论无头加压空心螺钉治疗第5跖骨基底部撕脱性骨折操作简单，固定牢靠，并发症少，疗效满意。%Objective To explore the curative effect of headless compression screws in treatment of avulsion fractures of the fifth metatarsal .Methods 37 cases of patients with avulsion fractures of the fifth metatarsal base were treated by internal fixation with headless compression screws from January 2008 to January 2011 .X-ray films after operation were taken to evaluate the bone healing time and the foot function was evaluated according to AOFAS .Results The 37 cases were followed up from 10 to 24 months (mean 13 months) .The X-ray films showed that all fractures healed at 6 to 12 weeks(mean 8 .1 weeks) .Wound infection occurred in one case with open fracture ,which was healed by therapy .According to AOFAS ,the scores after operation ranged from 86 to 100 (mean 94 .5) .Conclusion Headless compression screws in treatment of avulsion fractures of the fifth metatarsal has the advantages of easy manipulation ,stable fixation and few complications .
