The elbow joint is one of the most stable articulations in the body. There are three separate articulations: the ulno-trochlear (hinge), radio-capitellar (rotation) and the proximal radio-ulnar (rotation) joints. The close connection of these joints results in the high range of motion seen at the elbow with regard to extension and flexion as well as the pronation and supination of the forearm. Bone structures, the joint capsule, as well as the lateral- and medial-ulnar collateral ligaments allow direct motion control and high stability.
Injuries to the elbow are not common in football. Acute injuries are likely to occur during games and training. Overuse injuries in the elbow are more likely to occur as a result of supplemental training or due to factors outside the football pitch.
