Proximal Interphalangeal Joint Extension Block Splint

Abstract

Background: Extension block splinting of the proximal interphalangeal (PIP) joint is a simple and useful treatment option although the practical application of this technique has remained undefined in the literature. Methods: This article provides a step-by-step technique for the construction of a reliable PIP extension block splint and also reviews basic indications for treatment with a PIP extension block splint as well as other PIP extension block splint designs. Results: The proposed splint design outlined in this article is reliable, easy to reproduce and easy for patients to manage when treated with a PIP extension block splint. Conclusions: PIP extension block splinting has a role for certain injuries and certain post-operative protocols. A reliable splint design that is easy to manage makes this treatment choice more attractive to the surgeon and the patient.
