Document Summary
Quarter of all sports injury will be ankle sprains. Shape of bones, capsule and ligaments, and strength of muscles: bony ankle joint. Talus- allows for movement, wider at front than the back so when you go into dorsiflexion the wider portion now lies between the malleoli. More stability in dorsiflexion than plantar flexion relying on other things more (less bony stuff) when in plantar flexion. Atfl- weakest of lateral ligaments (he doesn"t agree thinks it jut doesn"t get as much help as the other ligaments) Stabilizes sub talar joint and limits adduction/medial tilt. Ptfl- strongest of all the lateral ligaments (also receives more bony support) Gets tight in extremes of dorsiflexion (best bony fit during dorsiflexion so its going to get a lot of help) Ankles sprains usually occur with loading and unloading. Because youre in plantar flexion (not a lot of bony fit). Injuries occur when there is not a lot of bony fit.
