Abstract
PURPOSE: The purpose of this study is to clarify the morphological characteristics of the lateral talocalcaneal ligament (LTCL). METHODS: This study examined 100 legs from 54 Japanese cadavers. The LTCL was classified into three types: Type I, the LTCL branches from the calcaneofibular ligament (CFL); Type II, the LTCL is independent of the CFL and runs parallel to the calcaneus; and Type III, the LTCL is absent. The morphological features measured were fiber bundle length, fiber bundle width, and fiber bundle thickness. RESULTS: The LTCL was classified as Type I in 18 feet (18%), Type II in 24 feet (24%), and Type III in 58 feet (58%). All LTCLs were associated with the anterior talofibular ligament at the talus. There was no significant difference in morphological characteristics by Type for each ligament. CONCLUSIONS: The LTCL was similar to the CFL in terms of fiber bundle width and fiber bundle thickness.
