ROCKWOOD PIN FIXATION OF CLAVICLE FRACTURES



Abstract

We are presenting a prospective study of 25 patients with clavicle fracture treated with Rockwood Intramedullary pin fixation. Operative management is required for open fractures, neurovascular injury or compromise, displaced fractures with impending skin compromise and displaced middle third fractures with 20mm or more shortening. Plate osteosynthesis or intramedullary fixation devices are used for operative management.

Patients and Methods: 25 patients with clavicle fractures underwent fixation of clavicle fractures with threaded intramedullary Rockwood pin. The indications for internal fixation were persistent wide separation of fracture with interposition of soft tissue in 12, symptomatic non-union in 3, associated multiple injuries in 3,one of them had a floating shoulder, impending open fracture with tented skin in 4 and associated acromioclavicular joint injury in 3 and one of whom had bilateral fracture clavicle.. All patients underwent open reduction through an incision centred over the fracture site along the Langer line. Intramedullary pin was inserted in a retrograde manner. Autologous bone grafting from iliac crest was done in all patients with nonunion. Radiographic and functional assessment conducted using DASH scores.

Results: There were 21 male and 4 female patients with a mean age of 34 yrs (range 17 to 64 yrs). Mean follow up was 12 months (range 5 months to 30 months). Radiographic union occurred in all patients within 4 months. In our study the commonest indication for Rockwood pin fixation was displaced middle third clavicle fracture followed by impending open fractures. Commonest complication was skin irritation at the distal end of the pin with formation of a tender bursa occurring in 9 patients, 3 of whom had skin breakdown. Fracture union occurred in all these patients with no further intervention and wounds healed completely after removal of the pin. One patient developed non-union and was later treated with ORIF with DCP and bone-graft. There were no deep infections, pin breakage or migration or re-fractures after pin removal. At the time of last follow up the average DASH score was 25 with a range of 18 to 52.

Conclusion: Open reduction and intramedullary fixation of clavicle fractures with Rockwood pin is a safe and effective method of treatment when surgical fixation of displaced or non-union of middle third clavicle fracture is indicated. This technique has an advantage of minimal soft tissue dissection, compression at the fracture site, less risk of migration and ease of removal, along with early return to daily and sports activities.
