Anterior Decompression and Fusion for Cervical Spondylotic Myelopathy
Unnanuntana A 
The result after anterior decompression and fusion for cervical spondylotic myelopathy
was retrospectively studied in 49 patients. There were 33 men and 16 women, their ages ranged
from 27 to 82 years (average 53.7 years). The most common level of involvement was C5-6•
followed by C3-4· Walking difficulty of various degrees in combination of numbness and
weakness of upper limbs were the most common presenting symptoms. The duration of preoperative
symptoms ranged from 1 month to 10 years (average 6 months). The functional results
at final follow-up were evaluated using the author's grading criterias. Mean follow-up time was
5.3 years (range 1-10 years). Forty-six patients were neurologically improved at various
degrees, three cases were unchanged, none had neurological deterioration. There was no time
limit of neural recovery as to the duration of disease prior to surgery. The potential cord
recovery might be partly affected by age, duration of the symptoms, and pre-operative functional
grade.
