Abstract |
Objective The objective of the study is to evaluate the effect of anterior cervical discectomy and fusion (ACDF) on
the improvement of gait in elderly patients with Nurick grade 5 by cervical spondylotic myelopathy (CSM), and discuss
the clinical and radiological predictors of outcome.
Methods We retrospectively analyzed patients with Nurick grade 5 (bedridden or chair bound) by CSM who received
an ACDF between 2005 and 2013. Data were collected on patient clinical characteristics and number of levels of
cord compression, high signal intensity, and cord compromise ratio in the preoperative MR imaging were investigated.
The patients were followed up for at least 6 months after the surgery and Nurick grade at last follow-up was
evaluated.
Results Nine patients were identified and mean age was 74.44±6.41 years. Eight patients were followed up for at
least 6 months. Statistically significant improvement on Nurick grade was found and the mean postoperative Nurick
grade was 3.75±1.28 (p=0.041). Five of 8 patients improved at least one degree on the Nurick grade at last follow-up.
Three of 8 were able to walk independently at last follow-up. No statistically significant prognostic factors for the improvement
on Nurick grade and regaining the ability to walk independently were found.
Conclusion About 60% of elderly patients with Nurick grade 5 by CSM improved at least one degree on Nurick
grade after ACDF, and about 40% of patients regained the ability to walk independently. In elderly patients with Nurick
grade 5 by CSM, ACDF could be positively considered as a treatment option. |
