The intrinsic subtalar ligaments have a consistent presence, location and morphology

Chronic subtalar instability is a disabling complication after acute ankle sprains. Currently, the literature describing anatomy of intrinsic ligaments limited and equivocal which causes difficulties in diagnosis treatment instability. The purpose this study to assess anatomical characteristics clarify some points confusion. In 16 cadaveric feet, dimensions locations were assessed measured. CT-scans before dissection indication footprints with radio-opaque paint allowed generate 3D models footprint characteristics. cervical ligament (CL) had similar as lateral ligaments: anterior length 13.9 ± 1.5 mm, posterior 18.5 2.9 talar width 13.6 2.2 calcaneal 15.8 3.7 mm. capsular (ACaL) interosseous talocalcaneal (ITCL) found be smaller structures consistent locations. This identified clarifies local situation. joint suggest more important role CL ACaL stability joint. results are relevant improve diagnostic tools offer guidelines when reconstructing injured ligaments.
