Abstract
Hemi joint replacements for the base of the first metacarpal of the CMC joint are provided which can effectively restore and reestablish functional joint mechanics while preserving the soft tissues that contribute to joint stability and function. The implants have a unique head shape with a saddle-like articular surface that is shaped somewhat similar to a conventional bicycle seat. A set of four proportionately larger and smaller implants allows a surgeon to choose the appropriately sized prosthesis for implantation in respect of the metacarpal osteotomy.
