<s>[INST] I had an MRI of my cervical spine done last Friday. Part of the report states that at C4/C5, irregular degenerative ventral disc/osetophyte complex notes asymmetric to the left superimposed uncovertebral disease. Partially effaces the ventral subarachnoid space. The only thing I understand is the part about the bone spurs and that uncovertebral refers to C3-C7 [/INST] Hi, In between the vertebra (bones in the back), there are discs.  Degeneration of the vertebra usually implies that there is arthritis of back. Osteophytes occur in arthritis. The spinal subarachnoid space is space in the spine which contains CSF. The imaging suggests that it is mildly affected. You should consider speaking to your neurologist or orthopedic surgeon. Hope I have answered your query. Let me know if I can assist you further. </s>
