Osteomyelitis of the clavicle.

Osteomyelitis of the clavicle is rare; however, it may occur following head and neck surgery. Risk factors include radiation, long-standing tracheitis, disruption of the periosteum or the cortical bone with interruption of the blood supply to the clavicle. Proper management includes early diagnosis, surgical debridement of soft tissue and bone, appropriate antimicrobial therapy, and coverage of the defect with a myocutaneous flap to protect the great vessels of the upper mediastinum.
