Fusion rate and patient satisfaction in proximal interphalangeal joint fusion of the minor toes using Kirschner wire fixation

Abstract

Proximal interphalangeal joint fusion using a Kirschner wire technique is common, but little critical evaluation of it has been published. The procedure was undertaken in 19 patients, in a total of 42 toes. The results were assessed at 6 weeks and at a special review clinic more than 6 months after surgery. Infection rate was low at 7%. Fusion occurred in 83% and was not related to operator seniority. Patient satisfaction was not directly related to fusion rate. Postoperative distal interphalangeal joint flexion or instability was as common a reason for dissatisfaction. Potential for avoiding this is discussed.
