The Ensemble CMC is intended to replace the first metacarpal and the trapezium in cases of theumatoid arthritis, traumatic arthritis, osteoarthritis, or post fracture deformation of bone loss which present as either a painful, unstable thumb, or a thumb with limited range of motion.

The Ensemble CMC implant is a single use, uncemented, one-piece interpositional joint prosthesis designed to fit in the space between the trapezium and first metacarpal for patients with early stage arthritis of the carpometacarpal joint (CMC). The Ensemble CMC is not intended to interact with other devices. It has upper and lower surfaces that are saddle (toroidal) shaped to match the anatomy of the base of the first metacarpal and the trapezium. The design of the Ensemble CMC allows for flexion-extension, abduction-adduction, and circumduction motions. The implant is manufactured with an On-X® PyroCarbon (pyrocarbon) layer encasing a graphite core and comes in three sizes. Each device is provided sterile in packaging containing a single implant, Instructions for Use, and patient chart labels. A series of non-powered, hand-held manual surgical instruments can be used to prepare the joint space before implantation of the Ensemble CMC.
