A broken arm in a car crash—a bone fracture—is an expected injury. Convalescing after breaking an arm in a car collision can include wearing a fiberglass cast, special brace, orthopedic splint, or an immobilizing sling. Each listed treatment method prevents unnecessary movement while the bones in your arm heal. This type of prevention of arm movement is called immobilization. If the auto accident impact does cause the bone to puncture the skin and the bones are well-positioned, you may only require arm immobilization to heal. However, surgery to repair the injury may be necessary if the bone breaks the skin, is pushed out of place, or is shattered in a car accident. Again, if surgery is required, immobilization will be necessary. How long recovery takes after a broken arm will vary from accident victim to accident victim.
