[Fractures of the clavicle and secondary lesions of the brachial plexus].

Abstract

The fractures of the clavicle are fundamentally minor and usually will heal by simple immobilization. When the trauma is severe, the fracture may cause a lesion of the subclavicular neuro-vascular bundle. However, if the lesion is limited it may appear clinically only a few days after the accident. In other cases, whether the clavicular fracture heals or not, the bone lesion may produce a hypertrophic callus. This phenomenon will cause a narrowing of the costo-clavicular outlet and a compression of the neurovascular bundle which will provoke a real TOS. The authors present 16 cases of clavicular fractures, two of which having had early neurovascular complications and the 14 others a late phenomenon of costo-clavicular syndrome. The pathogenesis of the lesions, the principles of treatment and the results are discussed.
