Histological Observation of the Ossification of the Supraspino us Ligament -Scanning Electron Microscopy and Transmission Electron Microscopy-

Abstract

The supraspinous ligaments, which were taken during surgery, were observed by means of SEM and TEM in order to clarify ossification process of the ligament. The fibrils of the supraspinous ligaments were 900-2000A in diameter and were almost parallel. Closer to the ossification, various changes were observed such as thinness and branching of fibrils, bridging between fibrils, irregular network of fibrils and deposits of granular substance.
