背景：目前多采用加压空心螺钉或可吸收螺钉置入修复第5跖骨基底部骨折，而国内对此类报道不多。目的：对比分析加压空心螺钉与可吸收螺钉置入内固定修复第5跖骨基底部骨折后患者足踝功能及骨折移位情况。方法：纳入2012年6月至2014年6月武汉大学中南医院收治的32例第5跖骨基底部骨折患者，根据内固定修复方式不同分为两组，加压空心螺钉组18例，可吸收螺钉组14例。根据两组骨折愈合时间、内固定后感染、足踝活动度及骨折移位情况评估修复效果。结果与结论：32例病例均获随访，随访时间6-18个月。两组均获得骨性愈合，但与可吸收螺钉组比较，加压空心螺钉组骨折愈合时间短(P <0.05)，内固定后出现断钉及骨折移位少(P <0.05)，足踝活动度良好(P <0.05)，具有一定优势。可吸收螺钉应提高其材料的强度，改善其螺钉螺纹，提高抗拔出特性，使患者早期行足踝活动，从而降低可吸收螺钉在临床使用的风险性。

BACKGROUND:The hol ow compression screws and absorbable screws can be applied for the treatment of the fifth metatarsal fracture. However, little evidence is obtained in China. OBJECTIVE:To compare ankle function and fracture displacement in patients with the fifth metatarsal fracture after interventions of hol ow compression screws and absorbable screws. METHODS:32 patients with the fifth metatarsal fracture were recruited from Zhongnan Hospital of Wuhan University between June 2012 and June 2014. According to the internal fixation method, the involved patients were divided into hol ow compression screws group (n=18) and absorbable screws group (n=14). Clinical outcomes of patients in the two groups were evaluated through observations of the mean healing time, postoperative infection, ankle activity and fracture displacement. RESULTS AND CONCLUSION:Al the 32 patients were fol owed up for 6-18 months and were al healed. Compared with the absorbable screws group, the healing time was shorter (P<0.05), incidence of postoperative screw rupture and fracture displacement was lower (P<0.05), and ankle activity was better in the hol ow compression screws group (P<0.05). It is necessary to enhance the strength, improve screw thread, increase anti-pul ing property, and al ow early ankle activity, thus reducing the risk of clinical application of the absorbable screws.
