The broken biceps muscle must be surgically sutured, and after the suture surgery, it is protected by external fixation with a brace or cast for 3-4 weeks, after which the broken area is considered healed, and the protection of the external fixation can be removed, and functional rehabilitation exercises for the elbow and shoulder joints in all directions can be performed. If you feel particularly hard at the beginning, you can massage and apply heat to the muscles around each joint to help loosen them. However, if the functional rehabilitation exercise is not effective, it may affect the movement of the shoulder and elbow joints and the strength of the upper limbs.
