A 39-year-old businessman recently took up squash in his leisure time. He started to complain of mild pain in the posterior aspect of his ankle while playing. Then, while playing, he heard a sudden snap in the lower calf associated with severe pain. He was able to walk with a limp but unable to run or stand on his toes and had to stop playing immediately. He is otherwise fit and well and his only recent medication has been a course of a fluoroquinolone for a chest infection.

Examination This man’s affected ankle has some swelling over the posterior aspect. On palpation, he has some tenderness over the Achilles tendon and a palpable gap. With the patient prone, squeezing the calf demonstrates no passive plantar flexion of the foot. What can be the probable diagnosis for this patient? *This case is from Docplexus editorial team for educative purpose only Source: Case reports in orthopedics
