title: Clinical course of the non-operated hand in patients with bilateral idiopathic carpal tunnel syndrome.
abstract: OBJECTIVE
  Patients with bilateral carpal tunnel syndrome (CTS) who had unilateral carpal tunnel surgery usually ask about the prognosis for the non-operated, opposite hand. In this study, we investigated the effects of unilateral carpal tunnel surgery on the clinical course of the non-operated, opposite hand in bilateral idiopathic CTS.
  
  
  METHODS
  In this prospective study, only patients who had bilateral idiopathic CTS but had unilateral carpal tunnel surgery were included. Sixty-six patients were included in the study. All patients were women with the mean age 47 years and mean duration of symptoms 4 years. Forty-six surgeries were performed on right hands, and 20 surgeries performed on left hands. Forty-eight (73%) patients were housewives. Their non-operated, opposite hands were evaluated before and 6 months after unilateral surgery. The evaluations consisted of subjective symptoms and objective findings. Paired t-test and chi-square test were used for statistical analysis.
  
  
  RESULTS
  There were no statistically significant differences between the means of symptom severity score, functional status score, power and pinch grip strength before and 6 months after unilateral surgery in the non-operated, opposite hands. There was no statistically significant differences among the percentages of the Tinel's sign, Phalen test, and electrophysiological changes before and 6 months after unilateral surgery on the non-operated, opposite hands. During the study period, 57 (86%) patients had surgery or intended to have surgery for their opposite hands.
  
  
  CONCLUSIONS
  It seems that unilateral surgery for bilateral idiopathic CTS does not affect the clinical course of the non-operated, opposite hand. We recommend that each hand of patients with bilateral CTS be managed separately, based on their symptoms.
