<s>[INST] hi, i have just picked up my ct scan of cervical spine & the conclusion reads...mild thecal sac stenosis is noted at c5/6 level due to left posterolateleft disc osteophyte complex. Mild narrowing of leftneural foramina is noted at c4/c5 & c5/c6 level.  Mild facet jouint arthropathy is noted at c7/t1 and c4/5 levels.   what does this mean?? [/INST] It simply means your cervical sac has narrowed canal causing compression on spinal cord, and secondary osteoarthritic (degenerative) changes have occurred with bone spike formation, the nerve roots are being compressed by bone spurs, narrowing of fora min and cervical joints are in varying degenerative changes causing pain, stiffness and nerve root compression symptoms. Disc is prolapsed in one place and further impinging on the thecal sac(covering on spinal cord) may be causing cord compression symptoms. You need spinal fusion, removal of prolapsed disc, and osteophytes etc </s>
