Biplanar Osteosynthesis for Severely Displaced Proximal-Third Clavicle Fracture: A Case Report.

Proximal-third clavicle fractures are infrequent injuries and are usually treated conservatively. They are associated with thoracic injuries or high-energy dorsal or cervical spinal trauma. In the case of displaced fractures and small medial fragments, orthopaedic management may have unsatisfactory results, creating symptomatic nonunions and functional limitation, we propose a biplanar osteosynthesis, which could be an effective treatment.
