spinal surgery

Dose my healing outcome decline with each spinal surgery I have.

I underwent an MRI of spine recently and the findings are as below

FINDINGS
There is exaggeration of lumbar largosis. All lumbar intervertebral discs exhibit signal changes-S/O desiccation. There are defects in bilateral L5 pars interarticularis with hypertrophic callus at the site of defect-S/O chronic spondylolysis. Grade II anterolisthesis of L5 over S1 is noted. Consequently, there is pseudobulge of L5-S1 disc which is indenting the thecal sac. There is marked bilateral foraminal narrowing with compression of exiting L5 nerve roots. There is mild retrolisthesis of L4 over L5. Consequent broad based dorsal protrusion of L4-5 disc is noted, indenting the thecal sac. Mild diffuse bulges of L2-3 and L3-4 discs is noted, abutting the thecal sac. Small left paracentral protrusion of L1-2 disc is noted, indenting the traversing left L2 nerve root. No significant nerve root compression or displacement. Blateral early facetal degenerative changes are noted at L5-S1 level. No significant ligamentum flavum thinckening. Rest of the intervertebral discs are normal in height, ontour and signal characteristics. Lumbar canal diameters at disc level are as follows:
L1-2 17mm
L2-3 16 mm
L3-4 16 mm
L4-5 16 mm
L5-S1 17 mm
The vertibral bodies are normal in height, morphology and signal characteristics. No evidence of spndylolisthesis. No abnormal pre or paravertebral soft tissue.

IMPRESSION
Exaggeration of lumbar lordosis. Bilateral L5 chronic spondylolysis with grade II spondylolisthesis of L5 over S1. Consequent pseudobulge of L5-S1 disc is indenting the thecal sac. There is marked bilateral foraminal narrowing with compression of exiting L5 nerve roots. Mild retrolisthesis of L4 over L5. Consequent broad based dorsal protrusion of L4-5 disc indenting the thecal sac. Mild diffuse bulges of L2-3 and L3-4 discs is noted, abutting the thecal sac. Small left paracentral protrusion of L1-2 disc indenting the traversing left L2 nerve root. No significant nerve root compression or displacement. No evidence of infective focus in the lumbar spine.

Kindly render your advice on the above.
