Q

A 69-year-old m an was walking down a flight of steps when he slipped and fell. On im pact, his left foot hit the ground and was forcibly inverted and m edially rotated. He stated that he felt som ething give on the lateral side of the dorsum
of the foot. Though shocked by the fall and the resulting foot pain, he was able to walk hom e. Within 2 h, the left foot and ankle had swollen considerably, which m ade exam ination by his physician difficult. Movem ents of the ankle were clearly possible, but inversion was extrem ely painful. On standing, the patient could bear his body weight without too m uch discom fort. The
