Proximal Interphalangeal Joint Arthrodesis of the Lesser Toes: 2-Part Design

Hammer toe deformity is one of the most common conditions affecting lesser toes that often requires surgical reconstruction including soft-tissue repair, resection arthroplasty, or arthrodesis. The success of the proximal interphalangeal arthrodesis depends on the lengthy period of postoperative pin care when percutaneous K-wire fixation is used. A 2-component polyether ether ketone intramedullary implant was designed to promote arthrodesis of the proximal interphalangeal joint by allowing a more reliable bone apposition and immediate stability at either 0 or 10 degrees of flexion. This treatment method theoretically avoids percutaneous K-wires while allowing early weight-bearing. Prospective clinical studies are required to elucidate the surgical outcome of this technique.
