title: An uncommon ankle sprain.
abstract: OBJECTIVE
  Ankle sprain is the most frequently occurring acute injury in tennis, accounting for 20-25% of all injuries. In the current paper, we assess the cause of ankle sprain and suggest possibilities to be considered during diagnosis.
  
  
  METHODS
  We assessed a professional tennis player with a partial tear of the long peroneal tendon after an ankle sprain by physical exam, X-ray and MRI.
  
  
  RESULTS
  Conservative treatment by means of soft cast and propriocepsis training led to full recovery.
  
  
  CONCLUSIONS
  Peroneal tendon disorders must be part of the differential diagnosis after ankle sprain in the professional athlete.
