Tibialis anterior partial tear. a, b Longitudinal gray-scale sonograms obtained over the two bands of distal tibialis anterior tendon. c Transverse sonogram. d MR STIR image corresponding to (c). In (a) the tendon band (black arrow) inserting onto the medial cuneiform (MCn) is torn. The proximally tendon is swollen, hypoechoic and retracted (broken arrow) to the level of the tarsal navicular (Nav). In (b) the tendon band (white arrow) inserting onto the first metatarsal is normal. Transverse US and MR images (c, d) show selective tear of the tendon band inserting onto the medial cuneiform (black arrows), the tendon band inserting onto the first metatarsal is continuous (white arrows)
