Description

A dynamic extension splint, known as a capener splint, is typically fabricated. It is a spring wire, three-point extension splint. It is designed to apply a small force to hold the joint at the end available extension range of movement (ROM), for long periods of time. Extension block splinting of the proximal interphalangeal (PIP) joint is useful for the treatment of some PIP joint fractures and dislocations or as part of post-operative rehabilitation, such as protection of the PIP joint volar plate repair.
