Nonunion of a midshaft clavicle fracture associated with subclavian vein compression. A case report.

Fractures of the clavicle are usually treated by closed means and heal uneventfully. In this report, we present an unusual case in which the subclavian vein was compressed by a fracture callus that had formed around a clavicular nonunion. Treatment included dissection of the subclavian vein from the fracture callus and compression plating with autogenous bone grafting of the fracture. Symptoms from the patient's venous obstruction slowly resolved without further treatment. The fracture united postoperatively.
