Trapezio-Metacarpal Joint Prosthesis


Achieving stability with a modular design

The design of the Maïa trapezio-metacarpal joint prosthesis is a result of the practical experience of a group of surgeons and analysis of long-term clinical trials.


  • An anatomical self-locking stem
  • A dual-layer coating that ensures optimal secondary stability and appropriate bone ingrowth into the metacarpal and trapezium implants.
  • A wide range of interchangeable necks to ensure overall stability.


  • Interchangeable sizes
  • Continued usual mobilisation of the thumb
  • Self-rehabilitation
