Arthrodesis of the Interphalangeal Joint of the Great Toe—An Improved Technique

Abstract

At the Mayo Clinic between 1950 and 1975, initial fusion of the interphalangeal joint of the great toe was attempted 166 times in 139 patients utilizing a Kirschner wire for stabilization. Follow-up examination of these patients disclosed an overall pseudarthrosis rate of 44%. Because of these disappointing results, a technique involving use of a longitudinal mini-cancellous bone screw was devised which provides increased stability and compression at the arthrodesis site. With this method, used 20 times in 18 patients, the pseudoarthrosis rate was decreased to 10%.
