Total metatarsophalangeal joint prosthesis, modular

A total metatarsophalangeal joint prosthesis, modular is an implantable device designed to replace the entire MTP joint of the toe, including both the metatarsal and phalangeal articulating surfaces. It is used clinically to treat conditions such as degenerative or traumatic arthritis, hallux valgus, hallux rigidus, or instability and pain in the big toe joint, restoring function and reducing discomfort.

This category of device is regulated as an implantable prosthesis and is typically supplied as a sterile, single-use system that may include modular components and associated disposable implantation instruments. Regulation is based on its implantable nature and intended use, with classification determined by jurisdictional medical device frameworks according to risk and invasiveness.
