Cervical herniation of the nucleus pulposus is not rare. Stookey,1 Love and Walsh,2 Mixter3 and many others have written extensively on this abnormality. However, rupture of the annulus fibrosus and protrusion of an ossified intervertebral disk causing complete transverse myelitis in the cervical region is rare.Horwitz4 in 1940 showed that degenerative changes in the cervical intervertebral substance occurred in 76 per cent of 50 unselected male cadavers examined by both roentgenograms and careful dissection. The average age at death was 56 years (the age of the subject of the present report) and the range was from 46 to 80 years. Narrowing of the joint space, irregularity of the articular margins, sclerosis of adjacent vertebral spongiosa and marginal proliferation of facets are the main changes of degeneration found by Horwitz. He reported complete ossification with fusion of adjoining vertebrae in 3 of the 50 cases studied. |
