title: Symptomatic os trigonum in children.
abstract: BACKGROUND
  Symptomatic os trigonum is a rare condition well described in adults responsible for chronic ankle pain. To date there is no published case of successfully managed symptomatic os trigonum in children.
  
  
  METHODS
  We retrospectively reviewed 4 paediatric patients (11-17) successfully operated on for a symptomatic os trigonum through a postero medial approach. One case was bilateral.
  
  
  RESULTS
  Pain relief was postoperatively obtained in all cases. All of the patients were able to return to physical activities after 3 months. The mean follow up was 12 months.
  
  
  CONCLUSIONS
  Symptomatic os trigonum may be responsible for chronic ankle pain in children and adolescents as well as in adults. The surgical treatment is effective in children.
