C5-6 ACDF with L4-5 Laminectomy

My 75 year old Dad will be having C5-6 ACDF with L4-5 Laminectomy at the same time on July 2nd. Has anyone done both of these at the same time? What can we expect as far as pain and recovery?

Medical Summary:
Symptoms are mostly a seeming lack of both strength and coordination of legs and my right arm/hand. Walking is much affected as with also a lack of balance. Limbs have a mild “burning” sensation after almost no effort. Limbs stiffen when bent for long periods. Can drive OK and feels “normal” (for his age) when lifting weights or on a stationary bike. That combination of symptoms intuitively makes little sense. It seemed to come on within just a few weeks, but with hindsight, probably more like a few months. On one earlier occasion, while walking with my mother, he mentioned he felt like he was “stumbling” rather than “gliding” with each step, but otherwise ignored the feeling.

He has had several Xrays and three MRIs which show severe spinal stenosis and other damage (a break and misalignment) to vertebra.

“Multilevel spondylosis characterized by disc osteophyte complexes, ligamentous thickening, and facet and uncovertebral arthropathy. Findings are greatest at C5-C6 where there is severe canal stenosis and mild mass effect on the ventral cord.” For this they will do a C5-6 ACDF.

“Lumbar spondylosis with degenerative disc and facet disease. There is a prominent, grade 1-2 spondylolisthesis of L5 over S1 secondary to bilateral L5 spondylolysis. There is a mild, grade 1, retrolisthesis of L4 over L5”. For this they will do an L4-5 laminectomy.

Thank you so much for your feedback!
