Abstract
Surgical biopsies of dissected transverse carpal ligaments of patients with idiopathic carpal tunnel syndrome were examined with an electron microscope revealing collagen fibrils with extremely varying diameters. Morphometric analysis was performed on photomicrographs exhibiting fibrils with a small diameter comparable to that in control tissue as well as fibrils with a far bigger diameter that could not be observed in control tissue. Morphometric parameters were evaluated in order to analyse the relation between number and covered area of collagen fibrils in control and in carpal tunnel syndrome tissue. In control tissue twice as many collagen fibrils as in pathological tissue occupied an equal area.
