Abstract

Objectives: The purpose of this study was to investigate the surgical efficacy and risk factors of cervical spondylotic myelopathy (CSM) patients with increased signal intensity (ISI) on T2-weighted magnetic resonance imaging (MRI-T2WI).

Methods: We compared the surgical outcomes of CSM patients with and without ISI. In addition, we compared the efficacy of anterior and posterior cervical decompression in CSM patients with ISI. We also analyzed the risk factors of MRI-T2WI ISI in CSM patients.

Results: The incidence of ISI among 153 CSM patients was 71.89 %. The JOA score and JOA remission rate were better in the ISI-free than in the ISI group. The postoperative JOA score and JOA remission rate were better in the posterior than the anterior approach surgery group. The disease duration and vertebral canal volume were found to be risk factors for ISI in CSM patients.

Conclusion: Among patients with CSM, the prognosis is worse for those with ISI than those without ISI. Posterior cervical decompression surgery produces a better curative effect than anterior cervical decompression surgery in CSM patients with ISI. CSM patients with longer disease duration and small vertebral canal volume should undergo surgical treatment as early as possible.

Keywords: Increased signal intensity, cervical spondylotic myelopathy, clinical efficacy, surgical approach, risk factors, vertebral canal.
