Digital arthrodesis: current fixation techniques

Several hammertoe implant devices have recently been introduced in an attempt to provide optimal fixation for proximal interphalangeal joint arthrodesis. This article reviews these implants individually, and discusses their advantages and disadvantages. There is a lack of research with long-term follow-up available for these devices. Percutaneous Kirschner-wire fixation persists as a time-honored and effective method of fixation. The buried Kirschner-wire technique is also an effective, cost-conscious option, with many of the same advantages as newer implantable devices.
