Abstract The aim of the present study was to evaluate and compare the clinical and radiologic results of internal fixation with a headless cannulated screw versus a locking compression distal ulna hook plate for fractures at the base of the fifth metatarsal bone, zone 1. From April 2012 to April 2015, 30 cases (29 patients) were retrospectively evaluated. The mean follow-up period was 13 months. The patients were divided into 2 groups stratified by the fixation method: screw (group A, n = 15) or plate (group B, n = 15). We measured the displacement to diastasis of the fracture on the foot oblique radiographs taken pre- and postoperatively in each group, recorded the time to bony union, and measured the difference in the reduction distance in each group. The clinical results were evaluated using the American Orthopaedic Foot and Ankle Society midfoot score at 12 months postoperatively. In group A, the mean interval to union was 54.2 ± 9.3 days, the mean displacement to diastasis had improved to 0.3 ± 0.4 mm postoperatively ( p
