The most common hand injury in skiing is a tear of the ulnar collateral
ligament of the metacarpophalangeal joint of the thumb.The
handle of the ski pole, the loop around the ski pole, or
the ground itself causes this. This is why it is known as
gamekeeper's thumb or skier's thumb.
Ulnar collateral ligament injury occurs in any sport when the thumb is forcibly
abducted, as occurs during a fall in sports such as hockey, football, and wrestling.
The thumb is pulled sideways and usually the ligament tears off at its distal
end where it is attached to the base of the proximal phalanx. Sometimes the ligament
remains intact but pulls off a bit of the bone to which it is attached. In either
case, Prolotherapy is very effective at treating the condition. A splint needs
to be worn for a few weeks if there is a fracture.
If the ligament is significantly torn, laxity at base of the thumb will be evident
by the thumb being displaced sideways, away from the index finger The athlete
is given a thumb spica splint and Prolotherapy is given to speed the rate of
healing. If the ligament injury is not too severe, Prolotherapy alone is done
to stimulate the repair of the injured structure.
