title: [Significance of double crush in carpal tunnel syndrome].
abstract: From June 1992 to October 1995, 224 patients were operated on carpal tunnel syndrome. We treated 71 male and 153 female patients. During our investigations, we found that one third of the patients suffered from a double crush syndrome. 84% of the patients suffered from one or more predisposing accompanying diseases. In most of them (42%) we found rheumatic diseases, 19% diabetes mellitus, 8% hyperuricaemia, and 6% hypothyreosis. In 33%, we observed a very short history and a bilateral carpal tunnel syndrome. According to the preoperative tests, four different groups of patients regarding electrophysiological parameters and the graduation of thenar atrophy were differentiated. The fourth group was composed of patients with double crush syndrome, who continued to complain of considerable pain despite surgery, the operated hand remaining both weak and awkward in its movements. Inspired by the prospective study by Dellon (1992) and our results, we will perform a retrospective analysis of the longterm effect of carpal tunnel release in diabetic neuropathy.
