The upper limb girdle bone includes two bones, the clavicle and the scapula. The upper limb girdle bone is the bone structure of the upper limb of the human body, including the clavicle and scapula two bones. The clavicle is an S-shaped bone connecting the sternum handle and shoulder joint, and the clavicle plays an important role in chest activities as well as upper limb activities and shoulder joint activities. The scapula is triangular in shape, located at the back of the thorax, with a glenoid at the lateral corner of the scapula, connected to the humeral head, constituting the shoulder joint, which can also play a role in increasing the range of upper extremity activities and upper extremity strength. The clavicle and scapula constitute the link between the trunk and the upper limb, and the scapula and clavicle are attached with tendons, ligaments and muscles, which are connected to the shoulder joint of the upper limb, and together they maintain the stability of the shoulder joint and participate in related activities.
