Brief summary
Subtalar instability is found in 30% of cases following a severe ankle sprain. Treatment is conditioned by subtalar involvement, so detection is essential. There is no consensus on the ligament anatomy of the subtalar region, making precise diagnosis of subtalar ligament damage difficult. The aim of this study is to provide a detailed description of the anatomy of the subtalar ligaments of interest, followed by a detailed radiological description (MRI).
