What joint is located at the connection between the clavicle and the scapula?

Under normal circumstances, the joint where the clavicle connects to the scapula is called the acromioclavicular (AC) joint. Detailed analysis is as follows:

The lateral end of the clavicle connects to the acromion process of the scapula via joint capsule and ligaments, forming a joint known as the acromioclavicular (AC) joint. This joint allows the scapula to make small movements around the clavicle—for example, assisting in adjusting the position of the scapula when raising the arm, thereby increasing arm mobility. At the same time, it transmits forces from the upper limb, reducing stress borne individually by the clavicle and scapula, maintaining stability of the shoulder's bony structure, and ensuring smooth performance of daily movements such as lifting and extending the arm. Because it connects the clavicle and scapula and plays a key role in shoulder movement, it is named the acromioclavicular joint.

In daily life, excessive strain or sudden force on the shoulder should be avoided—such as frequently lifting heavy objects or making vigorous swinging motions with the arms. Adequate warm-up exercises for the shoulder should be performed before physical activity to prevent joint injury due to sudden movement. If pain, swelling, or restricted movement occurs at the AC joint, timely rest and observation are necessary. Persistent symptoms should prompt medical evaluation to prevent impairment of normal shoulder function.
