title: Proximal interphalangeal joint silicone replacement arthroplasty: clinical results using an anterior approach.
abstract: Sixty-nine proximal interphalangeal joint silicone arthroplasties in 36 patients inserted through an anterior approach were reviewed. Average followup time was 3.4 years. The average extension deficit was slightly improved from 17 degrees to 8 degrees, but the total active motion (active flexion minus active extension) did not significantly increase (44 degrees to 46 degrees). Coronal plane deformities were not successfully corrected. Pain relief was obtained in 67 of 69 digits. There were 12 digits with complications, and five implants fractured. The anterior approach allows preservation of the central slip insertion and initiation of immediate active and passive joint motion. With proper indications, careful surgical technique, and a supervised therapy protocol, proximal interphalangeal joint silicone arthroplasty is a useful operation for pain relief and functional gain.
