Lateral ankle ligament injury following inversion ankle sprain.

The patient was a 20-year-old man who was referred to a physical therapist 6 weeks following an inversion sprain of his right ankle. Radiographs were completed and had been interpreted as normal, but due to continued complaints of instability and marked laxity on examination, ankle stress radiographs were ordered. Talar tilt stress radiographs were suggestive of lateral ligamentous insufficiency of the right ankle.
