The epicondyles of the humerus are part of the shoulder girdle and provide stability and flexibility to the arm. The lateral epicondyles of the humerus are two small structures that are located on the lateral side of the humerus. They help keep the hand in the correct position and provide stability when moving.
The lateral epicondyles of the humerus consist of bone tissue, which is covered with a thin layer of cartilage and muscle tissue. They provide strength and flexibility to the shoulder joint, and also help maintain the correct position of the arm during movement. In addition, the epicondyles provide stability to the shoulder joint during heavy lifting and other physical activities.
The lateral epicondyles also help form the joint that connects the humerus to the ulna. They participate in the process of hand movement and ensure its proper functioning.
However, if the epicondyles are damaged or removed, this can lead to dysfunction of the shoulder joint and limited mobility of the arm. In some cases, epicondyles may be surgically removed to treat certain conditions, such as arthritis or fractures.
Overall, the epicondyllae of the humeri laterally play an important role in maintaining the stability and functionality of the arm. They are also involved in the formation and functioning of the shoulder joint. Therefore, it is important to keep them healthy and prevent them from being damaged or removed in order to maintain normal hand function.
The supracondylar crest of the humerus, which has the highest lateral point of the surface of the acromion process, is located at an angle of 45° to the edge of the humerus and projects above the upper border of the lateral edge of the shoulder joint. The supracondylar foramen has a lateral border connecting it with the coronary groove, which runs in the area of maximum thickness of the lateral part of the scapula. The branch of the spinous process descends parallel to its anterior edge, almost touching its posterior edge and distantly communicating with each other the areas of the humerus and ulna.
