Abstract
A system for extending a finger of a hand comprises structural elements configured to be inserted into a flexed finger and capable of providing a controllable force to extend the finger. In some embodiments, structural elements comprise a cam connected to a spacer, the spacer connected to a first strut, and a second strut holding a loading assembly, an end piece and a spring. The loading assembly compresses or relaxes the spring, which exerts a variable force on the end piece, which rotates the cam and the first strut about an extension angle. When the extension angle is minimal, the first and second struts are substantially parallel. A method of extending a finger of a hand substantially fixed in a flexed position comprises inserting a system comprising structural elements into the finger and thereafter providing a force to extend the finger and maintaining the force for a period of time.
