Ankle is a complex mechanism consisting of two joints: the true ankle joint and the subtalar joint. MRI is increasingly being utilized in assessing patients with residual symptoms after initial conservative treatment because of its superior soft-tissue resolution.

Purpose. To highlight on useful role of MRJ in investigation about ankle ligaments injuries.

Materials and methods. A cross sectional study was carried out in Babylon teaching hospital from l st August 2021 to 1st September 2022. the study enrolled patients with ankle sprain. was performed with GE general electric 1.5 Tesla. For this purpose, the patients were positioned in a powerful magnetic field in supine position with feet first, ankle angle of 90 degrees. Data was collected and analyzed using SPSS 23.

Results. The study enrolled 40 patients with ankle pain the 26 female and 14 male with age range 20-50 years (mean age 36.1±8.4 year). Ligaments injuries by MRJ study revealed: 40% anterior talo-fibular ligament, 17.5% posterior talo-fibular ligament, 20% calceneo-fibular ligament, 15% deltoid ligament, 5%, anterior tibio-fibular ligament and 2.5% posterior tibio-fibular ligament were affected. Regarding to pathological finding, ligament sprain was seen in 16 patients, partial tear were found in 10 patients and complete tear of ligament present in 14 patients.

Conclusions. MRI is vitally significant in diagnosing abnormalities of ligaments and tendons of ankle trauma and plays a significant role in detecting lesions of tendons and ligaments.
