Purpose Awideinter-individualvariabilityintermsofsize,orientationandinsertionisobservedregardingankleligaments. The aim of this study is to identify and describe the anatomical features of the posterior talocalcaneal ligament (PTCL) observed through the use of magnetic resonance imaging (MRI) of the ankle.Methods The study was retrospectively carried out on 893 ankle MRI’s exams. The exams have all been performed using a 1.5-T (T) MRI. The same scanning protocols and scan planes were carried out in all the exams. The first evaluated param- eter was the recognition of the PTCL. Subsequently, in all those cases where the ligament was present, its features such as insertion sites, length, and thickness were evaluated.Results The PTCL identification was possible in 77 exams (8.6% of the total number). Among these, we were able to iden- tify some variants regarding insertion sites, length, and thickness. The PTCL could be further classified into four categories based on the most common characteristics observed.Conclusions Our study has identified different characteristics of the PTCL that allow us to further understand the charac- teristics of the ligament itself. In conclusion, the need for further studies focused on the biomechanical role of the PTCL in the ankle joint appears mandatory.
