摘　　要：目的探讨Acutrak无头加压螺钉治疗第五跖骨基底部的方法和临床疗效。方法2006年5月—2012年10月收治第五跖骨基底部骨折患者75例，其中男38例，女37例；年龄21—65岁，平均36岁。致伤原因：高处坠落伤35例，交通伤，23例，重物砸伤17例。左足29例，右足46例。术中采用Acutrak无头螺钉加压固定第五跖骨基底部骨折断端，保持骨折复位的稳定位，采用美国足踝外科协会（American Orthopedic Foot and Ankle Society，AOFAS）踝中足评分表进行功能评估。结果72例均获随访，平均时间15个月（13个月～5年），均获骨性愈合。术后切口均I期愈合，无并发症发生。术后1年AOFAS踝中足评分从术前（28.0±3.9）分（0～42分）增加至术后（93.0±6.5）分（79～100分）（t=7.650，P〈0.05）。患侧中前足肌力及外展外翻功能相对于健侧足差异无统计学意义。结论Acutrak无头加压螺钉内固定治疗第五跖骨基底部骨折，具有骨折断端加压固定可靠、并发症少、早期促进骨愈合等优点。Objective To investigate the methods and effects in repairing fracture of the fifth metatarsal base bone with Acutrak headless compression screws. Methods From May 2006 to October 2012, 75 patients with fracture of the fifth metatarsal base bone were reduced and fixed using Acutrak headless compression screws. There were 38 males and 37 females with a mean age of 36 years （ range, 21-65 years）. Injury arose from fall from height （35 cases） , road traffic accidents （23 cases） , and fall of heavy objects （ 17 cases）. Fracture of the left foot occurred in 29 cases and the right foot in 46 cases. Results were evaluated using American Orthopedic Foot and Ankle Society （AOFAS） ankle and midfoot score. Results Seventy -two patients were followed up for mean 15 months （range, 13 months- 5 years）. Operative incision obtained primary healing without any complications. Mean AOFAS ankle and midfoot score increased to （ 93.0±6.5） points （range, 79-100 points） at postoperative 1 year, com pared with the preoperative （28.0±3.9） points （range, 0-42 points） （t = 7. 650, P 〈 0.05）. Muscle force and valgus or abduction of mid-forefoot of the affected and unaffected sides demonstrated no significant difference after operation. Conclusion Acutrak headless compression screw system shows advantages of rigid fixation, few complications, and early healing in treatment of the fifth metatarsal base fracture.
