Lesser digit deformities that require surgical intervention may be corrected by interphalangeal arthrodesis. The traditional fixation device used to stabilize an interphalangeal arthrodesis is a smooth Kirschner wire (K-wire). Its use, however, has been associated with risks. The K-wires are known to migrate and break, and there are increased risks of pin tract infection. Choices for digital implants include nonresorbable, resorbable, and allograft. There are more than 60 newer intramedullary fixation devices available for use in digital surgery. Intramedullary implants also have their own inherent risks. Further research into patient outcomes and cost-effectiveness of these new devices is still needed.
