The fibular obscure tubercle was clinically relevant and reliable bony landmark of the ATFL and CFL origin location. However, the talar obscure tubercle was less reliable and the tuberculum ligamenti calcaneofibularis was rarely available and as such alternative landmarks for the ATFL and CFL insertion location should be utilized. The present study describes the utility of clinically relevant bony landmarks that may assist in identifying the origins and insertions of the ATFL and CFL to facilitate minimally invasive ankle stabilization surgery.
The superficial peroneal nerve demonstrated the greatest variance in its anatomy. An accessory incision to include the inferior extensor retinaculum in the repair should not surpass the 22mm distance from the lateral malleolus in the anterior direction, due to the risk of damaging the nerve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
