Abstract
Objectives
To evaluate the surgical outcomes and image by mid- sagittal MRI in patients with cervical myelopathy who were more than 70 years of age.
Summary of literature Review
Surgical outcomes of cervical myelopathy in the elderly patients were worse than in the younger patients, but decompression surgery is helpful for improving neurologic function in the elderly.
Materials and Methods
Nine patients more than 70 years of age who underwent surgery were reviewed. Neurologic deficits after surgery were assessed using a scoring system proposed by Japanese Orthopaedic A ssociation(JOA) and clinical results and morphological changes on MRI were compared with those of patients less than 70 years old age.
Results
The preoperative mean JOA score was 8.5 and the postoperative mean JOA score 12.8 and the maximum recovery rate was 51.1%, but these were significantly inferior to scores in those less than 70 years of age. A t the time of final follow up, the mean JOA score had decreased 11.3 and the recovery rate was 32.6%. All patients except one were improved their daily living function. On the postoperative midline T1 sagittal MRI, morphological improvement was seen in 44% in patients more than 70 years of age, while 69% of patients were improved in the control group.
