title: [Clavicular fractures after radical neck dissection].
abstract: Fracture of the medial end of the clavicle as a late complication following radical neck dissection is rare, with an incidence of approximately 0.4%-0.5%. Radical neck dissection alters the mechanics of the shoulder girdle, and distorts normal muscle forces acting on the clavicle. We present two patients to illustrate the problems of differential diagnosis and mechanism of fracture. Once the diagnosis has been made the fracture should be managed conservatively, although clinical and radiological differentiation from avascular necrosis or bony metastasis may be difficult. Biopsy is essential in doubtful cases.
