Tuberosity Supraarticular

The supraglenoid tuberosity (lat. tuberositas supraglenoidalis; synonyms: tuberositas, tuberositas epitrochlearis, tuberositas epicondylaris, tuberositas subacromialis, tuberositas acromialis) is a protrusion on the posterior surface of the humerus, which is located immediately above the glenoid cavity. This protrusion is crescent-shaped and serves to attach the muscles and ligaments that are involved in the movement of the arm.

The supraglenoid tuberosity is important for the normal functioning of the shoulder joint. It provides stability to the joint and protects it from injury. In addition, the tuberosity plays a role in transmitting force from the muscles to the joint, allowing the hand to perform various movements.

However, if the tuberosity is damaged or missing, it can lead to a variety of shoulder problems such as instability, pain, limited range of motion, and even injury. Therefore, it is important to monitor the condition of the tuberosity and, if necessary, consult a doctor for diagnosis and treatment.

The supraglenoid tuberosity is formed on the sides of the shoulder joint by the tubercles of the transverse process of the scapula.

It has a beak shape. On top of the tuberosity is the region of the capsule of the scapula, where the latter is fixed by the scapular-hyoid ligament. There are four to five on the tuberosities
