It is not recommended to leave the broken clavicle unattached. Clavicle not connected will not be able to support the local tissues, affecting the support function of the surrounding bones, causing movement disorders, especially on the upper limb, the impact is more serious, the range of motion of the shoulder joint on the affected side of the upper limb will be reduced. Long-term clavicle non-connection will cause long-term braking muscle activity less leading to muscle atrophy. If bone displacement occurs, it will irritate the surrounding soft tissues, causing local pain, redness, swelling, and even pus. In addition, the muscle strength will be affected, and the blood vessels and nerves around the fracture end will also be affected, which will also lead to thoracic outlet syndrome, mainly manifested as pain and numbness in the shoulder joint, arm and hand, as well as weakness. If the clavicle fracture does not recover in 9 months, it is considered to be a bone nonunion, which will have a very serious impact on the body. After clavicle fracture, it is recommended to actively cooperate with the doctor for treatment to avoid the occurrence of nonunion.
