title: Endoscopic treatment of Haglund's syndrome with a three portal technique.
abstract: OBJECTIVE
  The purpose of our study is to make a retrospective evaluation of endoscopic treatment of Haglund's syndrome using a new three portal technique.
  
  
  METHODS
  All 23 patients (25 heels) with a mean age of 27.7 years were evaluated pre-operatively and postoperatively with parallel pitch lines, the American Orthopaedic Foot and Ankle Society (AOFAS) score and the Ogilvie Harris score.
  
  
  RESULTS
  The mean follow-up was 41 months (range, 30-59 months). There were no obvious complications in our study. In 22 heels, postoperative lateral radiographs showed the achievement of negative parallel pitch lines. The average AOFAS score improved from 63.3 ± 11.9 points pre-operatively to 86.8 ± 10.1 points at final follow-up. There were 14 excellent results, seven good results, two fair results and two poor results. For the Ogilvie Harris score, there were 15 excellent, seven good, one fair, and two poor results.
  
  
  CONCLUSIONS
  An endoscopic procedure using the three portal technique seemed to be a safe and efficacious option for surgical treatment of Haglund's syndrome.
