Patient should always do their research! When doctors make claims of great success try to look at all options. However, remember there is a body of knowledge as a basis for much of the outcomes for surgical procedures.I try to show and explain to my patients goals of 70 to 80 percent are reasonable and try very hard to manage their expectations.Claims of a 100 percent should be suspect.Any procedure has real risk that should also be carefully reviewed by your surgeon. Having said all this, patients should remain optimistic as most procedures for acute disc herniations or spinal stenosis are quite successful with timely return to normal activity.
