title: Corticoid injection as a predictive factor of results of carpal tunnel release.
abstract: OBJECTIVE
  To evaluate whether the symptoms relief after local corticoid injection correlate with better results of surgical treatment in carpal tunnel syndrome.
  
  
  METHODS
  Between February 2011 and June 2013, 100 wrists of 88 patients were included in the study. All patients were subjected to corticoid injections in the carpal tunnel and evaluated before and after infiltration and surgery. The following parameters were evaluated: visual analog scale (VAS) for pain, Boston questionnaire, sensitivity and strength.
  
  
  RESULTS
  Only 28 out of 100 wrists subjected to injection were symptom-free after six months follow up. Sixty out of the 72 patients who did not present relief or relapse symptoms were treated surgically. Surgical results were better regarding VAS, Boston questionnaire and sensitivity in a specific group of patients, which had a longer relief of symptoms after the corticoid injection, with statistical significance.
  
  
  CONCLUSIONS
  Longer relief of symptoms after corticoid injection correlated with better results of surgical treatment.
