| ABSTRACT |
|
Patients admitted with the clinical symptomatology of a progressive myelopathy associated with radiologic findings compatible with spondylotic degeneration of the cervical spine and who manifest appropriate neurophysiological abnormalities should be considered as candidates for surgical treatment. The authors have undertaken a study of 20 patients who had received decompressive surgical procedures and possible follow up studies for CSM, which was defined as a myelopathy related to osteophytic overgrowth and ossification of posterior longitudinal ligament(OPLL) in the cervical spinal canal causing impingement upon the spinal cord from Sep.93. To Aug. 1995. It was concluded with the following results. 1) man was exclusively prevalent in most cases. 2) age at surgery: There was a signigicant negative correlation between the age at surgery and the recovery rate. 3) Original cause of compression: There was no signigicant difference between the CSM and OPLL. 4) The involved level : three level involvement was the most common(8cases), followed by two level(6 cases), four level(3 cases), and single level(2 cases). There was no correlation between the preoperative Harsh scale and the number of the involved level. 5) Recovery rate: excellent(Grade O.I). 12 cases(60%), good(Grade II, IIIA), 4 cases(20%), poor(Grade IIIc, IV, V), 4 cases(20%). |
