This paper reviews the first year’s experience with a new type of prosthetic implant for correction of arthritic disease of the proximal interphalangeal joint. Following FDA approval in March 2001, a one-year consecutive series of 45 implants in 32 patients has been performed. Of these patients, 11 had osteo arthritis, 10 had rheumatoid arthritis, and 11 presented with post-traumatic osteoarthritis. Preoperatively, pain was a significant factor, as well as decreased range of motion, deformity and joint instability. In this study, six to twelve 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 three (one open revision), flexor tenolysis in one, and excision of nodule and volar plate tightening in one. One patient was treated with manipulation and splinting adjustments for stiffness. The purpose of this paper is to report preliminary patient outcomes and to review the surgical technique and postoperative therapy and splinting protocols.
