The operative results of cervical myelopathy were evaluated in twenty-eight patients who were more than sixty-five years old. The mean age of the patients was seventy-one years (range, sixty-six to seventy-nine) at the time of operation (older patients group). Cervical disorders included CSM in 16 cases, CDH in 4 cases, OPLL in 6 cases, and OYL in 2 cases. We compared older patients group with non-older patients group (less than fifty-four years old) in the operative results, as well as a good-result group (more than 50% recovary ratio) with a poor-result group (less than 49% recovary ratio) in the older patients. The results were as follows; 1) the older patients group were greater than the non-older patients group in the severity of symptoms and duration of symptoms before surgery, worse than in the recovery of symptoms after surgery; and 2) the severity of symptoms before surgery of the poor-result group was greater than that of the good-result group.
