A fracture of the humerus in the right hand should be evaluated clinically and with X-rays to determine whether surgical or conservative treatment is needed. If the fracture is not heavily displaced or is only linear, and there are no symptoms of nerve injury or vascular injury, then conservative treatment is possible. You can use plaster for external immobilization, and then review the X-ray once a week to observe the position of the fracture. If the fracture is still in a good position, conservative treatment is enough. If the displacement of the fracture is more serious, with symptoms of radial nerve injury, such as inability to lift the wrist and fingers, or signs of vascular injury, such as poor peripheral blood flow in the upper limb. In this case, surgery is needed to fix the fracture internally, and at the same time explore the nerves and blood vessels, and repair the damaged nerves and blood vessels.
