AbstractThe purpose of this report was to evaluate patient outcomes after treatment of acute midshaft clavicle fractures with an intramedullary Hagie pin, including clinical results and the incidence of postoperative complications. Between 1993 and 2003, 16 patients who underwent intramedullary Hagie pin fixation of a midshaft clavicle fracture were identified. The medical records of each patient were reviewed to ascertain the mechanism of injury, indication for surgical intervention, and treatment course. Clinical outcomes were evaluated with respect to time to fracture union, postoperative shoulder range of motion, and symptoms related to the fracture site and ipsilateral shoulder. The inpatient postoperative course and outpatient follow-up visits were assessed in an effort to document the incidence of postoperative complications. The most common mechanism of injury was participation in athletic activity. Operative indications included significant deformity, polytrauma, and neurovascular compromise. The mean time from injury to operative fracture stabilization was 15.8 days. No intraoperative complications occurred. All 16 patients (100%) were available for follow-up to fracture union, which occurred in all cases at a mean of 12.4 weeks. Of the 16 patients, 14 were available for further follow-up, and at a mean follow-up of 9 months, 85.7% had regained near-full to full range of shoulder motion and 93% had no symptoms related to the fracture site or ipsilateral shoulder. Postoperative complications occurred in 8 patients (50%), including 3 cases of skin breakdown related to hardware prominence, 2 cases of hardware breakage, 2 cases of decreased sensation in the region of the surgical incision, and 1 case of persistent pain over the operative site. When indicated, the use of intramedullary devices for the stabilization of clavicle fractures offers theoretic advantages over traditional plate and screw fixation. In this case series, intramedullary Hagie pin fixation resulted in fracture union in 100% of cases, with a high percentage of patients regaining full range of shoulder motion and resolution of symptoms. However, there was a 50% incidence of postoperative complications associated with this treatment method. We believe that the complication rate associated with the use of the Hagie pin should preclude the use of this particular implant.
