Proximal Interphalangeal Replacement

The Proximal Interphalangeal Replacement is designed to replace the proximal interphalangeal joints in the hand.




In association with Mr I Trail FRCS, Wrightington Hospital.The PIPR™ is the result of in-depth study of the anatomy, soft tissues and biomechanics of the PIP joint and novel research into its bony morphology.

It is one of a very few devices to accurately mimic the kinematics of a healthy PIP joint. It uses materials and fixation techniques typically found in total knee replacement. The project is based on a research study of PIP dimensions and proportions.

Features include a unique, fully-conforming joint contact area, accurate press-fit stem geometry, unique geometry to help preserve collateral ligament attachments, limited interchangeability between sizes and advanced instruments to aid ligament balancing and stability

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

  • Relief from pain
  • Improvement in grip strength and function
  • Good range of motion
  • Low rates of revision
