*The joint capsule barely extends past the areas of articulation, except where it continues distally into the intertubercular groove of the humerus. This provides cushioning and synovial support for the bicipital tendon.

*The bicipital tendon and the joint capsule pouch are held in place by the '''transverse humeral retinaculum''', which lies betwwen the greater and lesser tubercles of the humerus.

*The radius articulates with the capitulum and lateral trochlear surface of the humeral condyle. Whilst the medial part articulates with the trochlear notch of the ulna.

*'''Annular ligament''' of the radius - attaches to the sides of the coronoid process of the ulna. This runs deep to the collateral ligaments and forms a ring for the radial head to turn in during pronation and supination.

*The radius and ulna are joined mid-shaft by the '''interosseous ligament'''; the remainder is filled by the interosseous membrane.
