Abstract
An orthopaedic splint is provided for treatment of injury to the extensor tendon distal to the DIP joint in the finger, the splint serving to hold the DIP joint in hyperextension and the PIP joint in flexion, while allowing restrained extension of the PIP joint. The splint suitably involves first and second portions each including at least one plate curved to seat transversely over or under a finger, the first portion also being longitudinally inclined and provided with strapping to hold the DIP joint in hyperextension, and the portions being resiliently and hingedly interconnected to hold the PIP joint as required. This interconnection conveniently involves like springs on respectively opposite sides of the PIP joint, the springs preferably being of mutually parallel flat spiral form.
