In conclusion, the need for further studies focused on the biomechanical role of the PTCL in the ankle joint appears mandatory.īartoníček J, Rammelt S, Naňka O (2018) Anatomy of the subtalar joint. Our study has identified different characteristics of the PTCL that allow us to further understand the characteristics of the ligament itself. The PTCL could be further classified into four categories based on the most common characteristics observed. Among these, we were able to identify some variants regarding insertion sites, length, and thickness. The PTCL identification was possible in 77 exams (8.6% of the total number). Subsequently, in all those cases where the ligament was present, its features such as insertion sites, length, and thickness were evaluated. The first evaluated parameter was the recognition of the PTCL.
The same scanning protocols and scan planes were carried out in all the exams. The exams have all been performed using a 1.5-T (T) MRI. The study was retrospectively carried out on 893 ankle MRI’s exams. 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. A wide inter-individual variability in terms of size, orientation and insertion is observed regarding ankle ligaments.
