Fig. 1From: Subtalar instability: imaging features of subtalar ligaments on 3D isotropic ankle MRISubtalar tilt angle on Broden’s stress view. Subtalar tilt angle is defined as the angle between lines drawn across the articular surface of the talus and the calcaneus. a Preoperative subtalar tilt angle was measured 15 degrees. b At 6 months postoperatively, the subtalar tilt angle decreased to 1 degreeBack to article page
