Radial head fractures are a fairly common injury secondary to falls on the outstretched forearm. Specific combinations of injuries involving radial head fractures and triceps tendon avulsion have been reported. Compartment syndromes secondary to distal forearm fractures are common; however fracture of the radial head rarely results in an acute compartment syndrome. A patient is reported with the combination of radial head fracture and triceps tendon avulsion complicated by the acute development of a compartment syndrome.
