Proximal interphalangeal joint prosthesis, modular

A proximal interphalangeal (PIP) joint prosthesis is an artificial implant designed to replace a damaged PIP joint in the fingers, often caused by arthritis or trauma. These modular devices consist of metal stems inserted into the bone, with articulating components—such as metal or plastic surfaces—to restore joint function and mobility.

These implants are typically regulated as surgical implants, requiring sterile packaging and adherence to orthopedic device standards. They may include specialized tools for precise placement, and classification varies by jurisdiction based on risk factors like fixation methods and material composition.
