Preliminary Report of Total Joint Replacement of the PIP Joint with a Pyrolytic Carbon Implant

ABSTRACT

The first year’s experience with a new prosthetic implant for correction of arthritic disease of the proximal interphalangeal joint was reviewed. Following Food and Drug Administration approval in March 2001, a 1-year consecutive series of 45 implants in 32 patients was performed. Of these patients, 11 had osteoarthritis, 10 rheumatoid arthritis, and 11 post-traumatic osteoarthritis. Preoperatively, pain was a significant factor, as well as decreased range of motion, deformity, and joint instability.

Six- to 12-month follow-up results are presented and show reduction of pain, improved range of motion, and stability of alignment. Five patients required additional procedures including reduction of subluxation in 3 (1 open revision), flexor tenolysis in 1, and excision of nodule and volar plate tightening in 1. One patient was treated with manipulation and splinting adjustments for stiffness. Preliminary patient outcomes are reported and the surgical technique and postoperative therapy and splinting protocols are reviewed.
