The Study Of The Clinical Prognosis Of Patients With Cervical Spondylosis Myelopathy And The Intramedullary High Signs On T2WI MRI

Objective: To explore the relationship of the clinical prognosis ofpatients with cervical spondylosis myelopathy and the intramedullary high signs onT2WI MRI. Methods: There were57cases of patients who were diagnosised ascervical spondylosis myelopathy from July2009to July2011in one tertiary hospitalwere divided into3groups according the different type of intramedullary high signson T2WI MRI in the research. The three groups were classified as no intramedullaryhigh signs on T2WI MRI(A group), faint and fuzzy border intramedullary high signson T2WI MRI(B group), intense and well-defined border intramedullary high signson T2WI MRI(C group). To explore the significance of the intramedullary high signsin evaluating the prognosis of the patients with cervical spondylosis myelopathy bymeans of reviewing and comparing the patients’ age,the duration of the disease, thecompression ratio of spine cord, the preoperative JOA, the postoperative JOA andthe recovery rates at the final follow-up. Results: There were34(59.65%) patientswatched intradullary high signs of the57patients, patients with faint and fuzzyborder signs(B group) was18, patients with intense and well-defined border signs(Cgroup) was16. Compaing the A、B、C group, there was not a statistical significantdifference(P＞0.05) in age, the preoperative JOA between these three groups. Therewas not a statistical significant difference (P＞0.05) between group A and B in theduration of the disease and the postoperative JOA; however, it showed a statisticalsignificant difference (P＜0.001) in these two areas between group A and B, group Band C. There exits no significance (P＞0.05) between group A and B, group B andC in the compression ratio of spine cord, it showed a statistical significant difference(P＜0.001) between group A and C. Conclusions: Patients with cervical spondylosismyelopathy who didn’t have the intramedullary high signs or had faint and fuzzyborder signs had a better recovery rates and clinical effects, however those who hadintense and well-defined border signs had a worse recovery rates and clinical effects.The clinical prognosis of patients with cervical spondylosis myelopathy is related to the patients’ age, the duration of the disease, the compression ratio of spinal cord, theintramedullary high signs and some other factors. The intramedullary high signs onT2WI MRI had a significance to estimate the clinical effects.
