Intramedullary fixation with k-wires is a surgical option in the management of fractures of the shaft and neck of central metatarsals. The current study aimed at investigating the clinical outcomes of closed antegrade/retrograde intramedullary pinning technique.
A total of 34 patients (26 males and eight females) with 58 metatarsal neck and shaft fractures (28 shaft and 26 neck fractures) were operated using the antegrade/retrograde intramedullary fixation technique. At the final follow-up visit, pain intensity was assessed using the visual analog scale (VAS) and foot function was evaluated by the American Orthopedic Foot and Ankle Society (AOFAS) forefoot scoring system.
Mean follow-up period was 18 months, ranged 12 to 34. Mean time to clinical fracture healing was 6.5 weeks, ranged 5 to 9. Bony union was occurred in all the cases. No surgical site infection was noted. Mean VAS score at the final follow-up visit was 0.28, ranged 0 to 3. At the final follow-up, the mean AOFAS score was 95.2, ranged 81 to 100.
Closed antegrade/retrograde intramedullary pinning is a minimally invasive technique to manage central metatarsal fractures. Using this technique, metatarsal alignment can be restored and good clinical outcome is achieved.
髓内固定克氏针是治疗跖骨干和颈骨折的一种手术选择。本研究旨在探讨闭合顺行/逆行髓内钉固定技术的临床效果。
采用顺行/逆行髓内固定技术对 34 例（26 例男性，8 例女性）58 例跖骨颈和骨干骨折（28 例骨干骨折，26 例颈骨折）患者进行了手术治疗。在最后一次随访时，使用视觉模拟评分（VAS）评估疼痛强度，使用美国矫形足踝协会（AOFAS）前足评分系统评估足部功能。
平均随访时间为 18 个月，范围为 12 至 34 个月。临床骨折愈合的平均时间为 6.5 周，范围为 5 至 9 周。所有病例均发生骨性愈合。无手术部位感染。最后一次随访时的平均 VAS 评分为 0.28，范围为 0 至 3。最后一次随访时，AOFAS 平均评分为 95.2，范围为 81 至 100。
闭合顺行/逆行髓内钉固定是治疗跖骨骨折的一种微创技术。使用这种技术可以恢复跖骨的对线，获得良好的临床效果。
