The CMI is designed to relieve basal thumb joint pain associated with early stage CMC arthritis. This pioneering pyrocarbon implant is intended to improve the thumb's range of motion and biomechanical function, and restore strength, mobility, and long-term stability to the failed or deficient trapeziometacarpal joint.
Its unipolar design and straight-forward surgical technique allow for near anatomical joint function.
The CMI system includes a procedure-specific instrument set, featuring a novel trapezium reamer, and sterile-packaged implants.
