Proximal Interphalangeal ReplacementTM

The PIPR™ is the result of in-depth study of the anatomy, soft tissues and biomechanics of the PIP joint[1] and novel research into its bony morphology[1].

The patented design uniquely preserves functioning collateral ligaments and allows for the natural combined rotation and angulation in the coronal plane during flexion, where alternative devices have oversimplified the PIP joint to a simple hinge. This is achieved with a fully conforming bearing couple that exhibits negligible wear [5].

With proven materials and press-fit cementless fixation, the device features all elements essential for implant longevity and is supported by a well-designed, accurate and repeatable surgical technique.

The PIPR™ has been in clinical use since 2006. Clinical data for the PIPR™ shows that it achieves:

  • Relief from pain [2-4],
  • Improvement in grip strength and function [2-4],
  • Good range of motion [2-4],
  • Low rates of revision [2-4].
