title: The lateral ligamentous support of the subtalar joint.
abstract: A review of the ligamentous structures spanning the subtalar joint laterally, as well as within the sinus and canalis tarsi, is presented based on previous descriptions and a series of anatomic dissections. Defined supporting structures are categorized into superficial, intermediate, and deep layers. Of these, the inferior extensor retinaculum is seen to be a discrete, substantial structure readily accessible for ligament reconstructions involving both the ankle and subtalar joints.
