Endoscopic spinal surgery affords the patient simplified and less
burdensome spine care. Its superiority over open decompression surgeries has been
long debated, and the current evidence is incomplete. The innovators and proponents of
this procedure carry the burden of proof. The targeted endoscopic treatment of common
spinal pain generators produces higher perioperative patient satisfaction than traditional
spine surgery. This chapter discusses conventional spine surgery research's pros and
cons of employing patient-reported outcome measures (PROM). They offer an
alternative approach to establishing a better value proposition with the endoscopic
versus open spinal surgery - the concept of durability analysis.
