The clavicle is located in the anterior aspect of the chest and is the only bony connection between the upper limb bones and the trunk bones. The clavicle is long and slender, superficial and susceptible to fractures caused by violence, and is one of the most common bone injuries. Early rehabilitation can help patients to recover their functions and return to society as soon as possible, thus reducing the burden on the family and the community and relieving the patient’s pain. The patient’s rehabilitation is divided into three phases: Phase I (1-2 weeks): The acute phase focuses on anti-inflammatory and pain relief, maintenance of muscle volume, and prevention and treatment of swelling. Therefore, the means of rehabilitation include low-frequency electrical stimulation of the muscles around the shoulder joint, along with icing, isometric muscle contraction training, and active movement training of the elbow and hand joints. Phase 2 (2-6 weeks): At 2 weeks postoperatively, finger grip training was increased, and passive or assisted exercises of shoulder abduction and adduction were performed to prevent joint adhesions. At 3 weeks postoperatively, increase shoulder flexion, extension, internal and external rotation training, as well as elbow flexion and extension and forearm rotation forward and backward resistance training, and do head and double elbow support chest raising training in the supine position. Isometric training of the muscles around the shoulder girdle should be started as early as possible for those with stable internal fixation. Stage 3: The third stage is when the fracture heals and the fixation is removed. The shoulder joint is a very flexible joint, capable of multi-directional movements, including flexion, extension, adduction, abduction, internal rotation, external rotation, horizontal flexion and abduction, as well as various compound movements of the shoulder joint. Mobility training should take care of all these directions to match the multi-directional activities of the shoulder, and train the muscle strength in each directional angle when doing mobility training. While doing the exercise therapy, we should also pay attention to the training of the patient’s daily life activities, so that the rehabilitation therapy can be carried out in the usual daily activities.
