AbstractThe purpose of this study was to present the results of the metatarsal fractures treated with a closed antegrade intramedullary pinning technique. The records of 35 consecutive patients with metatarsal fractures operated on from August 2005 to June 2010 by the authors were retrospectively reviewed. Four patients were not contactable and 1 patient refused to participate. Accordingly, the study cohort was composed of 30 patients (24 male, 6 female) with 46 metatarsal head, neck, or shaft fractures. Inclusion criteria were metatarsal head, neck, or shaft fractures with a displacement of more than 3 to 4 mm or an angulation of more than 10° in the sagittal plane. Fractures combined with Lisfranc injury or metatarsal base fractures were excluded, as were bicortical comminuted fractures or long oblique fractures. Times to bone union, limitations of motion at affected metatarsophalangeal joints, and residual pain were evaluated at 6 weeks after surgery and at final follow-up. American Orthropedic Foot and Ankle Society scale was evaluated at final follow-up. Fracture union was obtained at an average of 7.1 (range 6 to 10) weeks. Two patients had moderate limitation of metatarsophalangeal joint at 6 weeks but recovered to full range at final follow-up. Average American Orthropedic Foot and Ankle Society score at final follow-up was 96.7 (range 83 to 100) points. Closed antegrade intramedullary pinning was found to be a useful method for treating displaced metatarsal fractures and to allow immediate joint motion and partial weightbearing in a stiff-soled shoe.Copyright © 2012 American College of Foot and Ankle Surgeons.
