Fig. 4From: Subtalar instability: imaging features of subtalar ligaments on 3D isotropic ankle MRIA 27-year-old woman with subtalar instability. Sagittal (a) and axial (b) isotropic 3D T2-weighted images demonstrating intact inferior extensor retinaculum (arrowheads). er, ir, and mr indicate external, intermediate, and medial root of inferior extensor retinaculum, respectively. Cervical ligament represents a bundle of fan-shaped striated fibers (solid arrows). Sagittal (c) and coronal (d) isotropic 3D T2-weighted images demonstrating a thin and narrow anterior capsular ligament (open arrows). Solid arrows indicate cervical ligament with thin sheet-like fan-shaped striped fiber bundlesBack to article page
