Navigated Arthroplasty

Predictable and reproducible precision for every CMC arthroplasty

Eliminate complexity in case planning and managementwith a lightweight, surgeon-friendly navigation system.

Clinical Challenges

Thumb CMC arthroplasty can restore natural hand function but only if the trapezium cupis precisely placed

A misalignment of just 2° can weaken grip strengthand compromise long-term success

Surgeons rely on C-arm X-ray to guide CMC joint replacement but achieving the required level of accuracy is still dependent on extensive training and individual skill.

The result?

• Radiation exposure
• Slower set-up
• Inconsistent outcomes
• Limited adoption


Many surgeons will default to trapeziectomy, a simpler option but with a higher risk of grip function loss.
