This is an injury to the ulnar collateral ligament of the metacarpo-phalangeal joint. This is a strong ligament that supports the thumb when pinching or gripping and if it is damaged may lead onto to a chronic instability of the thumb which causes problems with function. The injury happens when you fall onto the outstretched thumb see diagram and is more likely if the thumb is gripping something at the same time.
The ligament can be injured when the thumb is bent back away from the fingers hyperextended. It is treated with immobilization or surgery. Cases that receive prompt treatment tend to have the best outcomes.
The injury may also be the result of falling on an outstretched thumb or catching a ball with an outstretched thumb. The injury may be relatively mild or complicated by an avulsion fracture of the proximal phalanx at the insertion of the UCL or a Stener lesion, present when both the proper collateral ligament and the collateral ligament are ruptured. Prior to initiating any treatment protocol, a careful examination of the thumb by a trained medical specialist is necessary to determine the extent of the injury and the appropriate treatment.
