title: Posterior tibiotalar ligament injury resulting in posteromedial impingement.
abstract: OBJECTIVE
  To describe the imaging features of the normal anatomy and injury of the posterior tibiotalar ligament (PTTL) of the ankle in a group of patients presenting with posteromedial impingement.
  
  
  METHODS
  Twenty-five consecutive patients underwent imaging for posteromedial ankle pain following injury. All 25 patients were investigated with MR imaging, 17 with ultrasound and 5 with radionuclide bone scanning. Clinical data and surgical findings were correlated with the results of radiological investigation.
  
  
  RESULTS
  The PTTL demonstrated scar formation and a hypertrophic response consistent with previous injury in all 25 patients. Displacement or encasement of the surrounding tendons and their sheaths was often encountered (12/25). Bony avulsion was demonstrated in 5/25 occasions with ultrasound and 2/25 with MR imaging. Twelve patients underwent surgery, confirming the radiological findings.
  
  
  CONCLUSIONS
  Imaging can effectively evaluate the integrity of the PTTL in the context of ongoing posteromedial ankle pain.
