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.

• Compact, close-to-field optical camera delivers sub-millimeter and fractional angular accuracy
• Lightweight bone-anchored registration and navigation
• Intuitive workflow with minimal interaction or training required
• Compatible with any K-wire placing system
• Adaptable to different implant systems and future partnerships
