Abstract

Study Design

A retrospective followup study comparing soft disc cervical myelopathy (Group A) and spondylotic bar cervical myelopathy (Group B).

Objectives

To analyze different factors by comparing preoperative radiological and clinical data of Group A with that of Group B.

Summary and Literature Review

The different causes of cervcal myelopathy resulted in different symptoms and prognoses.

Material and Methods

A clinical and radiological analysis of the data in 31 patients who underwent an anterior cervical decompression and fusion was performed to assess the different factors between two groups. The patients were classified into two groups; 20 in Group A and 11 in Group B. Comparisons between the two groups were made in regard to the physical findings, radiological and clinical evaluation.

Results

The duration of myelopathy was 3 months in Group A and 8.7months in Group B. Of all cases, 5 cases (25.0%) in group A and 4 cases (36.4%) in group B had myelopathy associated with radiculopathy. Of the 20 cases in group A with myelopathy,7 cases had a median compression and 13 cases had a paramedian compression on MRI. Of the 11 cases in group B with mey-lopathy, 9 cases had a median compression and 2 cases had a paramedian compression on MRI. The followup MRI of the 14 cases (73.7%) in group A and 2 cases (20.0%) in group B showed spontaneous regression of the T2 WI high signal intensity.

Conclusion

In degenerative disc disease, the different causes of cervcal myelopathy result in different symptoms and prognoses. However, the treatment of choice in both groups is a one level anterior decompression and fusion.
