Complications of a clavicle fracture can include injury to the subclavian nerve as well as the brachial plexus nerve. Injury to the subclavian nerve is caused by local compression or local compression of the fracture fragment due to the fracture. Injury to the brachial plexus nerve is caused by excessive violence to the clavicle. After the clavicle fracture, there may be some external rotation or abduction of the shoulder joint, resulting in a pull on the brachial plexus nerve, which leads to a radical avulsion injury of the brachial plexus nerve. Under normal circumstances a clavicle fracture must be checked for damage to the brachial plexus nerve. If there is damage to the brachial plexus nerve, early surgical treatment is required to restore the plexus nerve. For rotator shoulder or other changes in the shoulder, and to prevent excessive impact on shoulder joint movement and limited function of the upper extremity.
