A thumb sprain is an injury to a ligament, which is a soft tissue that connects bones to each other at joints, as opposed to a thumb fracture (break) which is an injury to the bone. Many times, thumb sprains will result from sports injuries or falls. For example, skiing results in many thumb injuries, as does basketball. Or, you may fall and try to catch yourself, bending your thumb in an awkward position.
