Proximal Interphalangeal Replacement™
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.
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 .
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
Improvement in grip strength and function
Good range of motion
Low rates of revision
The PIPR™ is unique in its protection of the bony support for the ligaments and allowance for the combined rotation and angulation in the coronal plane during flexion, where alternative devices have over simplified the PIP joint to a simple hinge.The PIPR™ has been in clinical use since 2006 with over 700 implanted worldwide.
Throughout an extended series followed up at the Wrightington, good outcomes have been maintained
In a published series of 100 implants followed up for a minimum of 2 years, maximum 6 years 5 months the PIPR™ was shown to achieve:
