Thumb Sprains
A stable, or healthy and uninjured thumb is extremely important for both pinching and grasping. “Jamming” or spraining your thumb causes an injury to the main ligament in the thumb, aka, the ulnar collateral ligament. A ligament is a soft tissue that connects two bones and helps create a stable joint. Tearing this ligament can not only cause pain and lack of mobility, but can also cause your ability to pinch and gasp to become weak and/or non-existent.
