Head of the Humerus

Is an anatomical structure formed above by the articular surface of the head of the shoulder joint, to which the tendon cuff is attached, and below by the glenoid cavity of the shoulder joint. In the neck of the humerus there is a glenoid fossa - the location of the head of the humeral condyle. Deep in the neck, under the transverse axis, there is an intercondylar eminence on which the intercondylar notch is located.

The head of the humerus is part of the girdle of the upper limb and consists of three separate surfaces: anterior, posterior and intercondylar and is covered on the sides and in front by a developed periosteum, which is a continuation of the connective tissue capsule of the shoulder joint. The upper surface of the head of the humerus has the shape of a spherical bone, narrows upward and along the edge forms pits for the vessels and nerves of the same name.

However, the humeral head is one of the most commonly injured areas of the humerus. Damage of the most common nature: bruises, cracks, fractures in the area of ​​the intermuscular fossa, and often dislocations of the humerus due to a blow, fall or any other impact on the limb. It's all about insufficient fixation of the lumbar muscles: injuries often arise from physical activity with a weak, unresisting system of tendon and muscle formation.
