Lateral ankle ligaments injury

Case contributed by Dr Maulik S Patel


One week prior to the ultrasound, the patient had a left ankle inversion injury while running between the wickets at cricket. Immobilization was done on the same day. He was referred for an ultrasound to check the lateral ankle ligaments.
