SUBTALAR ARTHRITIS

Abstract

The subtalar articulation is the major and most important joint of the

foot. I It consists of two components, the talocalcaneal or subtalar joint,plus I the talonavicular and calcaneocuboid that comprise the transverse tarsal I joint. I I Here we discuss the subtalar arthritis in the following chapters: 1- Anatomy of the subtalar complex I 2- Biomechanics of the subtalm• complex I 3- Pathology of subtalar arthritis I 4- Diagnosis I 5- Management I It is important to discuss the anatomy of the subtalar complex in the I .. form of skeletal and articular anatomy, as all structures in the subtalar . complex can be affected in case of mthritis. I I Ir1 generally the axes of motion of the subtalar complex. are fairly I parallel to each other in a horizontal plane. The main motion about the I

subtalar joint is that of inversion and eversion.

The overall motion will be changed when anatomic or pathologic I changes affect the parallelism of the axes or when one or more of the I

joints becomes limited. I I Subtalar arthritis can be grouped into six broad classifications: I
