ABSTRACT:
An adjustable finger support for the proximal interphalangeal joint of a finger of the human hand including an elongated, hinged support base adapted with means for securely, yet comfortably holding the finger in place throughout the course of treatment. The elongated base is divided at the hinge into respective support sections for the proximal phalangeal portion of the finger and the middle phalangeal portion of the finger. Jacking mean, such as a screw jack in the form of an elongated set screw operates in conjunction with hinged attachments to the respective undersides of the proximal and middle interphalangeal support sections to 1) maintain the set position of the angle of the respective base portions and 2) to provide firm, controllable extension of the joint over a wide range by selective operation of the jacking means.
