This is the summation I think;
There are degenerative changes of the lumbar spine. At L4-L5 there is moderate spinal stenosis with moderate left and right neural foraminal stenosis.at L5 S1 there is a broad based disc bulge with a superimposed right paracentral protusion which abuts the decending right S1nerve root.
There is facet joint degeneration. There is mild to moderate left neural foraminal stenosis.
