SURGERY FOR OLD ATLANTOAXIAL DISLOCATION WITH BULB-SPINAL CORD COMPRESSION-A REPORT OF 32 GASES / 西安交通大学学报(医学版)

32 patients with old atlantoaxial dislocation with bulb-spinal cord compression were treated surgically from 1971 to 1989. Their diagnoses were confimed mainly by X-ray examination and measurement. The average time of follow-up after operation was 6 years. The rate fo excellence and good was 87.5% per cent. The causes of atlantoaxial dislocation, operative techniques involved and results are discussed. The authors think that the key to the increase of the therapeutic effects is early diagnosis and surgical treatment before the irreverisible changes of bulb-spinal cord compression occur.
