Avanta CMC

Arthroplasty System

The CMC implant is used to treat joint arthritis of the thumb.

Small joints

The components are coupled together using a snap fit. The "ball and socket" design allows for 90° of conical articulation that permits radial circumduction of the CMC joint. The implant is provided with instrumentation to aid in bone preparation and proper size determination.

  • Offered in various sizes to accommodate anthropomorphic variations in trapezio-metacarpal sizes.
