Abstract
We report a retrospective review of 224 proximal interphalangeal joint arthrodeses in the digits using Herbert screws (37), Kirschner wires (100), tension band wiring (69), plates (11), and other miscellaneous techniques (7) for fixation. Average time to clinical union was 7 weeks and time to radiographic union was 10 weeks. Nonunion occurred in 31 cases (24 digits). The primary nonunion rate was highest in psoriatic arthritis, intermediate in rheumatoid arthritis, lower in acute trauma and post-traumatic reconstruction, and nonexistent in osteoarthritis. The primary nonunion rate was highest using Kirschner wires, intermediate using tension band wires, and lowest using Herbert screws. All Kirschner wires, six tension band wires and one Herbert screw were removed after fusion. The Herbert screw provides secure fixation, is easy to insert, and affords a rapid and reliable arthrodesis at the proximal interphalangeal joint.
