Abstract
Percutaneous endoscopic lumbar discectomy PELD can be performed under local anesthesia with intravenous analgesics To define the incidence of piriformis syndrome PS after PELD via the posterolateral approach under local anesthesia compared to that of general patients presenting with low back pain with/without lower leg pain The incidence and time of occurrence of positive FAIR test after PELD within a 3month followup period were evaluated retrospectively and compared with the prevalence of general patients who visited the pain clinic for LBP with/without lower leg pain Factors that may increase the incidence of PS after PELD were also evaluated There was no patient with positive FAIR test immediately after PELD in the operation room and before walking The prevalence of PS in general patients was 317/2320 137 however the incidence of PS after PELD within a 3month followup period was 61/151 404 peaking at 32 days High anxiety scale scores during operation led to increased incidence of PS after PELD PELD under local anesthesia with high level of anxiety may increase the incidence of PS after walking peaking around the first month compared with the results for general patients with low back pain with/without lower leg pain
