The main symptoms arise from a myelopathy, the degree of which varies from moderate to severe, due to stenosis of the spinal canal. In order to clarify the relationship between the severity of symptoms and the cross-sectional area of ossification, axial transverse tomography of the cervical spine has been carried out on twenty-six patients at intervals of 5 millimetres over the full extent of the ossification. In this way the cross-sectional areas of the ossified tissue and of the spinal canal were calculated. The former varied from a minimum of 0.8 to a maximum of 1.8 square centimetres. In cases of severe myelopathy the ossification was mainly at the fourth and fifth cervical levels and the stenosis ration exceeded 30 per cent. <\/jats:p>","DOI":"10.1302\/0301-620x.59b4.411796","type":"journal-article","created":{"date-parts":[[2018,2,21]],"date-time":"2018-02-21T11:29:35Z","timestamp":1519212575000},"page":"481-484","source":"Crossref","is-referenced-by-count":11,"title":["Axial transverse tomography of the cervical spine narrowed by ossification of the posterior longitudinal ligament"],"prefix":"10.1302","volume":"59-B","author":[{"given":"K","family":"Hanai","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Adachi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H","family":"Ogasawara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","container-title":["The Journal of Bone and Joint Surgery.
