Comparison of Complication Rates of Intramedullary Pin Fixation Versus Plating of Midshaft Clavicle Fractures in an Active Duty Military Population

Abstract

Military service members have increased requirements of shoulder weight bearing to perform duties. Operative intervention has increased for treatment of displaced middle one-third clavicle fractures. Complications of operatively treated clavicle fixation have not been extensively studied. A retrospective, longitudinal cohort chart evaluation was conducted of all active duty members undergoing fixation of middle one-third clavicle fractures, for complications between intramedullary pin fixation and plate constructs. This review found 62 patients meeting inclusion criteria. Thirty-three patients underwent intramedullary pin fixation with Hagie pins and 31 patients underwent precontoured superior clavicle plate fixation of their middle one-third clavicle fractures. Complications included wound infection, skin and/or soft tissue irritation, and need for unplanned hardware removal. The overall complication rate was 31% in the plate fixation group versus 9% in the intramedullary pin group (p = .024). All patients achieved fracture union with return to duty; however, increased overall complications were seen in the plate fixation group.
