There is loss of continuity of the ulnar collateral ligament of the thumb at its distal attachment site. Controlled stress view shows joint space widening. The ruptured ligament is deep to the adductor aponeurosis. There is no associated bony avulsion.
Comparison with asymptomatic side is done, which shows an intact ligament.
