Bilateral Displaced Midshaft Clavicle Fractures Following High-energy Road Traffic Trauma: A Case Report and Review of the Literature.

Abstract

Abstract: Bilateral clavicle fractures represent one of the rarest patterns of shoulder girdle trauma, occurring predominantly after high-energy mechanisms and posing unique challenges in diagnosis and management. Their simultaneous disruption compromises both clavicular struts, resulting in impaired shoulder biomechanics and necessitating timely stabilization for optimal functional recovery. A 25-year-old male sustained high-velocity trauma following a motorcycle accident and presented with severe bilateral shoulder pain, deformity, swelling, and markedly restricted arm elevation. Neurological and distal vascular examinations were normal. Radiographs demonstrated displaced bilateral midshaft clavicle fractures (Allman Group I), with no associated thoracic or systemic injuries. Due to significant displacement and bilateral involvement, open reduction and internal fixation was performed using 8-hole titanium anatomical locking plates on both sides through an anterior approach. Stable fixation was confirmed intraoperatively. Early pendulum exercises were initiated, followed by progressive passive and active range-of-motion rehabilitation. Postoperative recovery was uneventful. At 1 month, the patient achieved shoulder abduction of 110° on the right and 100° on the left, with full muscle strength bilaterally. Serial imaging demonstrated progressive fracture consolidation with maintained anatomical alignment. Bilateral displaced midshaft clavicle fractures, though rare, can be effectively managed with anatomical locking plate fixation, providing stable reconstruction and permitting early mobilization. This case reinforces the value of operative intervention in high-energy bilateral clavicular injuries, contributing to the limited but growing evidence guiding treatment of this uncommon trauma pattern.
