The elbow joint is a motor complex made up of three distinct joint bindings in the same capsule – the humeroulnar joint, the humeroradial joint, and the proximal radioulnar joint. This joint plays a crucial part in the free and coordinated movement of the entire upper limb (the arm). Whereas the shoulder girdle ensures a large range of spatial motion, the elbow joint ensures a precise positioning and extension of the arm. Biomechanically speaking, in addition to the three joints that comprise it, we should include one more in the area of the wrist; thanks to it, the arm and hand assume their necessary position in order to accurately and effectively perform their function. Damage to any segment of the elbow complex leads to disrupted functionality in the others.
