Morphological characteristics of the lateral talocalcaneal ligament: a large-scale anatomical study
- 65 Downloads
The purpose of this study is to clarify the morphological characteristics of the lateral talocalcaneal ligament (LTCL).
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.
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.
The LTCL was similar to the CFL in terms of fiber bundle width and fiber bundle thickness.
