Lamenotomy and lamenectomy

Hi. Has anyone undergone a lamenoctomy or lamenectomy (spelling?)?
Our spine doctor has recommended a lamenenectomy for my 84 yr old husband who suffers from pain in his upper right thigh, has PAD though MRI reveals pain shows tangled and inflamed nerves in his back. Cardiogist concurs. Suggested procedure was to have 1-3 spinal epidurals to lower the inflammation and then follow up with a lamenectomy which surgeon says helped his dad to walk again. Husband had one epidural and felt no difference. Was told the first epidural probably would be no effect on upper thigh pain, two more epidurals might be required to lower the inflammation followed bt a lamenectomy. Our co pay for the epidurals is $250 so hubby refuses to spend that amt again. He is in constant pain with some relief from opioid but cannot walk but a few feet on his walker and even turning over in bed causes him severe pain.
Understandably he is afraid to have the lamenectomy, but by doing nothing he'll never walk again and sits in chair 12 hours a day. Any experience with these two types of surgery to release the painful nerves that are causing him severe leg pain? He does not have any pain in his back and therefore thinks the doctor is wrong. Any success stories??
