Hello and welcome to HCM,
In order to understand the MRI and CT report you need to understand the anatomy of the
spinal cord and surrounding structures.
The spinal cord is a delicate tissue enclosed in the
vertebral column.
A pair of 31 spinal nerves emanate from the spinal cord and traverse the bony vertebral column through foramina and recesses.
The MRI and
CT scan shows that there is presence of scar tissue or dense
connective tissue which is abutting the spinal nerves at the level of L5 and S1 from the level L5-S1.
Compression of the nerve by any structure leads to symptoms in the region supplied by these nerves at distant site.
In your case the compressing structure is the scar tissue.
Scar tissue is formed as a result of healing or regeneration of tissue.
You need to consult a orthopedician as well as
neurologist for removal of the scar tissue and relieving the nerves from compression.
Thanks and take care
Dr Shailja P Wahal
