Injuries that cause a muscle to pull away completely from the bone are called tendon avulsion injuries. In this case, the tendon that holds the muscle to the bone is detached. Because they contain no blood vessels, tendons heal slowly after being injured in any way. Non-surgical treatment of muscles pulling from the bone includes rest, ice, compression and elevation (known as RICE). However, in cases of severe injury, surgery is required to re-attach the tendon.
Rest. Take a break from whatever you were doing to cause your injury. Depending on where the tendon avulsion injury occurred, your doctor may require you to wear a supportive device such as a brace, cast, splint or crutches to keep the injured area in a neutral position and allow it to heal.
Ice your injury. Apply cold packs for up to 20 minutes at a time, three to five times each day.
Compress the area of the injury to prevent more swelling and/or blood loss. An elastic compression bandage should be wrapped snugly (but not too tightly) around the injury.
Elevate the injury. Depending on the location of the injury, another way to reduce swelling is to lay back and keep your injured area higher than your heart.
Perform the rehabilitation exercises recommended by your doctor if your injury is not severe and after the pain and swelling has calmed down. Initial therapy, such as gentle stretching, first focuses on flexibility and aims to restore range of motion. Later, more exercises can be incorporated to build up strength which also helps in the healing process. Therapy will also be required after corrective surgery.
Undergo surgery. To repair a tendon avulsion injury, a surgeon must pull the muscle back into place and remove any scar tissue. The tendon is then reattached to the bone using large stitches or staples.
When icing your injury, do not apply ice directly on the skin.
If surgery is performed to treat your injury, you must keep the injured area stable to speed up recovery and prevent further injury .
