BackgroundIntramedullary 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.Patients And MethodsA 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.ResultsMean 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.ConclusionClosed 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.Copyright © 2020. Published by Elsevier Ltd.
