A specialized immobilizing splint that is adapted for protection of an injured thumb, where the person who sustained the injury may continue activities with the diminished risk of re-injury. A skier with an injury to the ulnar collateral ligament (UCL) may use this splint to immobilize the thumb without diminishing the strength of his grip. The glove is the basic element that retains the splinting device and maintains it in place. The plastic splint gives support to the thumb at the metacarpophalangeal articulation and the associated ulnar collateral ligament. The tensioning strap assists the thumb in its gripping motion because of the positioning of this strap in relation to its point of attachment. The thumb is also protected from hyperextension in the areas where it is supported.
