Lateral approach to proximal interphalangeal joint implant arthroplasty.

Arthroplasty of the proximal interphalangeal joint is indicated for arthritic conditions that fail to respond to conservative treatment. This article describes the lateral approach for the insertion of a proximal interphalangeal joint implant arthroplasty. Clinical experience has confirmed good results in the nonlaborer with arthroplasty of all the digits. Ten surgeries have averaged 68° of motion with a range from 50° to 80°. No patient has required a revision 3 years after surgery.
