The proximal interphalangeal joint swing traction splint.

Conventional PIP joint flexion splints exhibit several shortcomings regarding kinematic and kinetic behavior. A new PIP joint swing traction splint (STS) has been developed to overcome these shortcomings while maintaining the advantage of the ease of use of conventional simple rubber band traction devices. This article defines the advantages of the STS system in terms of physics and also describes the fabrication technique involved.
