Methods: Prospective data for patients operated at the Department of Neurosurgery, St. Olavs University Hospital, Norway, were obtained from the Norwegian Registry for Spine Surgery (NORspine) from 2007 to 2012. The primary outcome was change in Oswestry disability index (ODI) at 1year. The secondary endpoint was perioperative complications. Complications were graded according to the Ibanez classification system. Results: For all patients (n = 125), the mean improvement in ODI at 1year was 16.9 points (95% CI 13.5-20.2, p < 0.001). Seventy-six (71.7%) patients achieved a minimal clinically important difference in ODI (defined as ≥8 points improvement). The total number of complications within 3months of surgery was 22 (17.6%). There were 14 medical and eight surgical complications, and all were Ibanez grade I or II (mild or moderate) complications. Four (3.2%) complications occurred while being admitted to the hospital and 18 (14.4%) occurred within 3months following hospital discharge. The most common complication was urinary tract infection (n = 11, 8.8%). Conclusions: Microsurgical decompression for central LSS in the absence of radiological instability is an effective and safe treatment.
