Abstract
We compared ultrasound (US) with magnetic resonance (MR) findings of muscle tendon and ligaments (mt&l) of 17
men and 13 women, 16–66 years old, who suffered from acute ankle injury without bone fracture visible on conventional
radiographs. Joint effusion (JE), and injury of the Tibials anterior muscle tendon (TAmt), Calcaneofibular ligament
(CFl), Long flexor of the great toe muscle tendon (LFGTmt), Short peroneus muscle tendon (SPmt), Long peroneus muscle
tendon (LPmt), and Anterior talofibular ligament (ATFl) were assessed by the US, at seven days, and MR, at seventeenth
day. Grading of ligament and muscle tendon injury as stretching (Grade 1), partially ruptured (Grade 2), and
complete rupture (Grade 3); no lesion was considered to be Grade 0. Joint effusion and ATFl were the most common lesions
whereas the TAmt lesion was the least frequent: JE ~ ATFl > SPmt ~ LPmt > LFGTmt ~ CFl ~ TAmt. Both US
and MR were equally sensitive in detecting the presence (or absence) of the mt&l ankle injury, whereas US was less specific
than MR in detecting G3 injury.

acute ankle injury, ultrasound, magnetic resonance, anterior talofibular ligament Introduction Ankle joint injuries are common trauma particularly associated with the lateral ligament sprain induced by the adverse forces acting upon the collateral ligament complex. The degree of the ankle joint injury vary in intensity of damage such that it may be classified as stretching (Grade 1; G1), partially ruptured (Grade 2; G2), and completely ruptured (Grade 3; G3) muscle tendon and ligament1. There is a general consensus that the great majority of G1 and G2 ankle joint injuries heal uneventfully with conservative care. However, the treatment of G3 ankle joint injury is debatable since some practitioners prefer operative repair (especially for the top athletes), whereas others prefer casting and a physical therapy regimen1. Diagnosis of ankle joint injury involves the conventional radiograph to eliminate fractures and routine ultrasound to evaluate
