The figure-of-eight splint for proximal interphalangeal joint volar plate injuries.

Volar plate disruption of the proximal interphalangeal (PIP) joint is a common hand injury. Management of this injury must provide stability and motion to avoid disabling instability or stiffness. In this study, 40 patients with closed PIP joint volar plate injuries were treated with the figure-of-eight splint, a custom made, thermoplastic splint that allows protected joint motion. At two-year follow-up, 95% of these patients experienced good or excellent results. The figure-of-eight splint offers a simple and effective method of treatment for volar plate injuries of the PIP joint.
