A comparison of outcomes of carpal tunnel release for carpal tunnel syndrome in patients diagnosed with and without electrophysiological studies.
The aim of our study was to determine the incidence of operative treatment for carpal tunnel syndrome in Denmark and to see whether there was a consensus about the place of preoperative electromyography and nerve conduction studies. A questionnaire was mailed to all surgical departments (n = 70) and all registered private surgical practices (n = 214) in Denmark. The incidence of operation was about 0.61 per 1,000 population. Most surgeons used preoperative electromyograms and nerve conduction studies in less than 50% of cases. The use of preoperative testing was related to the surgical speciality.
