Injuries to the fingers of the hand can substantially limit mobility and dexterity. Moreover, continued use of injured fingers without proper support can exacerbate pain, as well as joint, tendon and tissue damage. These realities are compounded among persons who rely heavily on their hands for work or recreation. Among this group are, for example, landscapers, construction workers, and athletes of all levels, from recreational to professional. A common finger injury among certain athletes is hyperextension resulting from the rearward being of the finger beyond its natural range of motion. Among the measures taken by athletes to prevent initial or further finger injury of already-injured fingers is the wrapping of fingers in tape. For more severe injuries, a finger might be secured to a splint with athletic tape. Even taping substantially limits mobility, and is nevertheless a time-consuming process that must be repeated before practices and games. Splinting is a less temporary measure, but results in very limited mobility. Accordingly, there exists a need for a finger brace and associated finger support system that can be readily installed about one or more fingers, adjusted, removed and reinstalled, while allowing an acceptable range of finger motion required for task performance.
