Abstract
Eight athletes developed symptomatic nonunions of the base of the proximal fifth metatarsal in the metaphyseal region. All of the athletes were initially treated conserv atively without success. We reviewed their case histo ries and outlined a simple, effective, low morbidity surgical management of these lesions. Two nonunions successfully healed with internal fixation with an intra medullary compression screw. Five additional non unions were shelled out through a lateral incision of the peroneus brevis without disturbing its insertion. An eighth nonunion fragment was large and articulated the cuboid; it was fixed successfully with an intramedullary compression screw to preserve lateral foot mechanics. There were no complications. All patients returned to full activities 2 to 4 months after surgery.
