Retrospective Analysis Of Anterior Operation Of Cervical Spondylotic Myelopathy

Objective: To study the operation results of anterior operation of cervical spondylotic myelopathy and relationship between disease course, degree with treatment result. Method: 67cases with cervical spondylotic myelopathy treated by anterior decompression were reviewed. Relationship between disease course, degree with their treatment results were analyzed. Result: The JOA scores rise markedly after operation, paired /-test for dependent samples is used to estimate the difference, there is statistics difference of JOA scores between preoperation and postoperation (t=-12.915 P=0.000) .The treatment result between two groups of different disease course has statistics differences (t=7.629 P=0.000), and the treatment result among four groups of different disease degree has no statistics differences (F=1.313P=0.278).ConcIusion: Anterior operation is an effective operative method to treat cervical spondylotic myelopathy. The operation result has relationship with disease course,so operation should be performed as soon as possible when cervical spondylotic myelopathy is diagnosed exactly and the satisfactory result will be achieved by proper operative way.In a certain degree,even some low JOA scores cervical spondylotic myelopathy patients with short disease course whom can be performed operation as soon as possible,the satisfactory result of treatment also can be obantained. The operation result has no relationship with disease course,but it should be continued to study.
