<unk> s are common. Typically they are caused by direct blows to the elbow (e.g. motor vehicle accidents), and due to falls when the triceps are contracted. "Side-swipe" injury when driving a motor vehicle with an elbow projecting outside the vehicle resting on an open window's edge is an example. Direct trauma: This can happen in a fall with landing on the elbow or by being hit by a solid object. Trauma to the elbow often results in comminuted fractures of the<unk> . Indirect trauma: by falling and landing with an outstretched arm. Powerful pull of the triceps muscle can also cause avulsion fractures.
