Techniques

Scaphoidectomy and 4-corner arthrodesis can be a successful salvage procedure for scaphoid nonunion advanced collapse and scapholunate advanced collapse. Traditional methods of fixation include Kirschner wires, staples, and/or headless compression screws. Nonlocking, dorsal circular plates, manufactured from stainless steel, have been advocated to allow early wrist range of motion and improved union rates. However, the reported union rates have been variable and inconsistent. This wide results have been attributed to the difficulty in assessing union with plain film radiograph due to the radio-opaque plate. Recently, a locking, dorsal circular plate, comprised of a radiolucent polyether-ether-ketone (PEEK-Optima), has been introduced with the additional benefit of providing a fixed-angle construct and allowing a more accurate assessment of bone union with plain film imaging studies.
