Ensemble CMC lateral approach

The Ensemble CMC™ is a one-piece, interpositional joint prosthesis designed to fit between the trapezium and first metacarpal for patients with early-to-mid stage arthritis of the carpometacarpal joint (CMC). The Ensemble CMC™ implant has upper and lower surfaces that are saddle shaped to mimic natural CMC joint anatomy. Its design allows for flexion-extension, abduction-adduction, and circumduction motions.

The implant is manufactured with an On-X® Carbon layer encasing a graphite core and is provided in sterile packaging. The three Ensemble CMC™ sizes correspond to the anatomic variations in the cross-section of the joint, specifically the Radial/Ulnar and Dorsal/Volar dimensions.
