Total Joint Arthroplasty of the Proximal Interphalangeal Joint
ABSTRACT
Prosthetic arthroplasty of the proximal interphalangeal joint has been generally limited to silicone devices for approximately 40 years. Although silicone proximal interphalangeal arthroplasty can be successful in the ulnar digits, it is generally not performed in the index finger because of the inability to withstand pinch forces.
A cemented and noncemented polyethylene, metal, and a pyrocarbon prosthesis have been developed to allow total joint replacement at the proximal interphalangeal joint. The devices may be used in all fingers and commonly provide >70º of postoperative motion. The surgical technique and clinical results of each device will be presented.
