Superficial femoral artery branch avulsion after severe muscle cramping.

Avulsion of a muscular branch of a major artery without a history of major trauma has not been reported to our knowledge. Occasionally, blunt and even minor trauma can result in injuries that seem out of proportion to the level of injury. We report a case of an avulsed muscular branch of the superficial femoral artery in a patient with recent thigh cramping. This injury is likely related to the intense tetany the patient described having before he came to the hospital.
