Could thumb-base instability after skiing or ball sports be skier’s thumb?

Doctor’s answer

Yes. Skier’s thumb usually refers to injury of the ulnar collateral ligament of the thumb metacarpophalangeal joint, often after a fall onto the hand, ball-sport contact, or forced opening of the thumb. Mild injury may use splinting; complete tear, obvious instability, or Stener lesion usually requires hand-surgery assessment.
