... Persistent spinal pain syndrome (PSPS) is a new term proposed by the International Association for the Study of Pain to define chronic or recurrent pain of spinal origin and replaces older, potentially pejorative terms such as "failed back surgery" [1][2][3]. PSPS is divided into type 1 (no previous surgery) and type 2 (relevant previous surgery; PSPS -2), which affects 20% to 40% of patients who have had spine surgery [1]. Despite the growing, aging population with PSPS-2, there is no consensus regarding the optimal treatment for this condition [4]. ...
