The SR™ PIP (Proximal Interphalangeal) Implants are designed to replicate the anatomic joint surfaces, preserve bone and minimize disruption to the collateral ligament origins and insertions. The kinematic behavior closely mimics that of a normal joint when the soft tissues are well preserved.

The SR™ PIP (Proximal Interphalangeal) Implants consists of two pieces. A ultra-high molecular weight polyethylene (UHMWPe) component and an titanium alloy stem that has a external surface to allow bone growth.

The cobalt chromium surface articulates with the UHMWPe component to form a semi-constrained prosthetic replacement for the proximal interphalangeal joint. The implant is available in five sizes, each of which can be used in right or left hands. A range of trial sizers for each type of implant is available to aid in bone preparation.

The SR™ PIP is approved for use with or without cement. Therefore it is cement optional.

• Designed to replicate anatomic joint surfaces, preserve bone, & minimize disruption to the collateral ligaments

• Pain Relief – Recent studies have concluded that the anatomic designs of the SR family of finger implants can provide pain relief & restore joint kinematics for patients requiring finger joint arthroplasty

• Extended Range of Motion – ROM & function may be restored without artificial constraints or damage to ligaments or tendons

• Stable, Long Lasting – The congruent semi-constrained articular surfaces minimizes stress concentrations, allowing the implants to withstand the demands of everyday hand functions

• Proven Materials – These unique two-piece designs utilize the same proven biocompatible materials found in hip and knee replacements; cobalt chrome, titanium alloy & UHMWPe

• Anatomic Sizing – Each implant is available in multiple sizes to address varied patient anatomy

Available in the United States as a Humanitarian Use Device.
