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
