ORIGINAL ARTICLE Surgical fixation of displaced midshaft clavicle fractures: elastic intramedullary nailing versus precontoured plating

Background This prospective comparative study was done to evaluate the effectiveness of implants of different design (titanium elastic intramedullary nail versus ana-tomical precontoured dynamic compression plate) in treatment of displaced midshaft clavicular fractures. Materials and methods Sixty-six patients between 18 and 65 years of age were included in this study. They were randomized in two groups to be treated with either elastic intramedullary nail (EIN) or plate. Clinical and radiologi-cal assessments were performed at regular intervals. Out-comes and complications of both groups over 2 years of follow-up time were compared. Results Length of incision, operation time, blood loss and duration of hospital stay were significantly less for the EIN group. American Shoulder and Elbow Surgeons (ASES) and Constant Shoulder scores were significantly higher (p \ 0.05) in the plating group than the EIN group for the first 2 months but there was no significant difference found between the two groups regarding functional and radio-logical outcome at the 2-year follow-up. Significantly higher rates of refracture after implant removal (p = 0.045) in the plating group was observed. Infection and revision surgery rates were also higher in the plate group, but this difference was insignificant (p [ 0.05). Conclusions EIN is a safe, minimally invasive surgical technique with a lower complication rate, faster return to daily activities, excellent cosmetic and comparable func-tional results, and can be used as an equally effective alternative to plate fixation in displaced midshaft clavicle fractures.
