X-rays of the thumb, hand and wrist to rule out fractures. Prolonged healing time if usual activities are resumed too soon. Proneness to repeated injury. Unstable or arthritic thumb following repeated injury. If this is a first-time injury, proper care and sufficient healing time before resuming activity should prevent permanent disability.
Ligaments have a poor blood supply, and torn ligaments require as much healing time as fractures.
Follow your doctor's instructions. These instructions are supplemental. See Appendix 1 for details. Place ice chips or cubes in a plastic bag. Wrap the bag in a moist towel, and place it over the injured thumb.
