对63例上肢的腕管面积以及腕管内容9腱1神经进行了观察,腕横韧带做了组织学检查.发现腕横韧带弹力纤维仅占15～20％;腕管面积与9腱1神经面积总和之比为3.3:1。这样,腕管内的结缔组织为腕管内容提供了一定的活动空间。由于腕横韧带与正中神经接触的局部关系恒定。故此腕管综合征产生的原因,是否可以认为,腕管是缺乏伸展性的骨纤维邃道,任何足以引起腕横韧带变性都将增加正中神经与腕横韧带的接触,而致正中神经受压,尤其在腕背屈时更为明显。 The carpal tunnel area of ​​63 patients and the content of 9 tendon and 1 nerve in the carpal tunnel were observed. The transverse carpal ligament was examined by histology. The transverse ligament fibers were found to be only 15-20% The ratio of area to total is 3.3: 1. In this way, the connective tissue in the carpal tunnel provides a certain amount of space for the contents of the carpal tunnel. As the transverse carpal ligament and median nerve contact with the local relationship is constant. Therefore, the causes of carpal tunnel syndrome, whether it can be considered, the lack of extensibility of the carpal tunnel bone fracture, any sufficient to cause degeneration of the transverse carpal ligament will increase the median nerve and transverse carpal ligament contact, and the median nerve compression , Especially when dorsiflexion is more obvious.
