Six months after clavicle fracture surgery, the patient can not lift the arm, according to the cause of general treatment, drug treatment, physical therapy and surgical treatment, etc. Consider the lack of functional exercise leading to joint adhesion, nerve injury, fracture has not healed and other factors. 1. Lack of functional exercise leading to joint adhesion: because of shoulder joint adhesion, shoulder joint functional exercise should be strengthened, and passive shoulder abduction, forward flexion and backward extension exercises can be given first, and then gradually transitioned to the healthy arm assisting the affected side to climb along the wall, pendulum movement, and active touching of the mouth and the back of the head. During the exercise period, massage, hot compresses, physical therapy (microwave), oral pain medication (celecoxib capsules) and medication to relieve muscle spasm (cloxacillin tablets) should be used. If joint adhesion is serious and conservative treatment is ineffective, joint release surgery can be considered. 2. Nerve injury: because of the nerve injury, usually the axillary nerve leads to shoulder abduction limitation, can be given nutritive nerve drugs (methylcobalamin tablets), oral 2~3 months, if improved, can continue oral medication, strengthen the functional exercise, if the symptoms do not improve, the upper arm muscle atrophy, can be given to surgical exploration to repair the nerve. 3. Fractures not healed: Fractures not healed due to pain can not lift the arm, should continue to support the fixed, non-weight-bearing functional exercise. There may be other reasons why you can’t lift your arm after clavicle fracture surgery, so we suggest that you actively seek medical advice, complete the relevant examinations, clarify the cause of the disease and then treat it under the guidance of your physician.
