Subtalar joint arthrodesis

Abstract

Isolated subtalar joint arthrodesis has gained popularity more recently. Research has shown that it preserves rearfoot motion, does not increase the risk of arthritis in adjacent joints, and is not an especially complex operative procedure. It decreases the chance of midtarsal joint nonunion and malunion postoperatively. This article takes an in-depth approach to isolated talocalcaneal fusions. Anatomy and biomechanics of the subtalar joint are reviewed. Clinical presentation and radiologic evaluation are discussed. Conservative treatment, operative technique, and postoperative management are included.
