23例慢性压迫性颈脊髓病手术治疗的回顾研究

目的 探讨慢性压迫性颈脊髓病压迫程度及MR表现与术后功能恢复的相互关系。方法 选择三年中通过认真减压治疗的颈脊髓病23例,再经过1～3年的临床随访及MR复查。采用JOA评分法进行功能评价,并对MR图像进行测量与观察。结果 减压前、后椎管截面积分别为59.4mm~2和103mm~2;脊髓截面积分别为50.8mm~2和81.48mm~2;脊髓矢状径分别为5.6mm和 7.79mm;JOA评分分别为 6.5分和 9分。以上指标手术前、后比较均有显著性差异(P<0.001)。结论 慢性压迫性颈脊髓病通过手术减压可明显改善脊髓形态,同时改善脊髓功能。

Retrospective Study of Operative Effect of Chronic Cervical Spinal Cord Compression(23 cases)

Objective To study the relationship between compressive extent, MR imaging and postoperative functional restoration of the chronic compressive cervical myelopthy. Methods 23 cases of cervical spondylosis had been performed decompression treatment in the past 3 years. MR observation and measurement ,JOA assessment had been mad in all above patients in 1 - 3 years clinical follow-up. Results The cross arca of the spinal canal was 59. 4mm2 and 103mm2 respectively pxe-operation and posf operation; the cross arca of the spinal cord was 50. 8mm2 and 81. 48mm2 respectively; The saggittal siameter of the spinal cord was 5. 6mm and 7. 79mm respectively, the JOA assessment was 6. 5 and 9 respectively. There were siguifi-cant difference (P<0. 001) in all above indexes preoperation and postoperation. Conclusion form of spinal cord with chronic compresive cervical myelopthy should be improve by docompersion, as well as the spinal cord function.
