How long it takes for a dislocated arm to heal depends on the severity of the dislocation and the treatment, and cannot be generalized. The moment the arm is dislocated, the joint capsule and ligaments will be damaged to varying degrees, and the patient needs to go to the hospital urgently to have the dislocation reset by an orthopedic surgeon with local anesthetic traction. After the manual repositioning, the patient needs to be fixed with a cast or brace to help promote the healing of the joint capsule to avoid recurrent dislocations and habitual dislocations, and can generally recover in 3-4 weeks. At the same time, patients can take oral blood-activating and pain-relieving drugs or apply safflower oil topically to reduce swelling. If the dislocation is accompanied by a fracture or vascular nerve injury, the healing time may need to be extended by several weeks accordingly, and the exact time varies from person to person. After dislocating the arm, the patient needs to take care of strict braking for 3 weeks before moving the joint to avoid sequelae.
