For a study, the researchers determined the number of patients prospectively enrolled in Danespine in a propensity match. The goal of the research was to look at individuals with lumbar spinal stenosis (LSS) who had a wide laminectomy (WL), segmental bilateral laminotomies (SBL), or unilateral hemilaminectomy (UHL) with bilateral decompression over 5 years. The best LSS procedure is still up for debate. Micro-laminectomy, Hemi-laminotomies, wide laminectomy, and laminectomy with instrumented fusion have all been proven to have similar short-term outcomes in the research. Patients with spinal stenosis who had WL0, SBL, or UHL with bilateral decompression and were enrolled in DaneSpine at 2 spine centers from January 2010 to May 2014 were identified. Patients completed standard questionnaires before surgery, as well as 1, 2, and 5 years later. Age, sex, BMI, smoking status, number of surgical levels, American Society of Anesthesiologists (ASA) score, and patient-reported outcome indicators were used to propensity-match patients in the three cohorts (PROMs). In each category, propensity matching yielded 62 examples. At the five-year follow-up, there were no variations in PROM between the 3 cohorts. At the index level, 12 patients were re-operated. Repeat decompression following SBL was the most common reason for reoperation. Age, sex, number of operated groups, ASA score, BMI, center, smoking status, and having a dural rupture at index operation were all found to have no statistically significant relationships with reoperation. At 5 years after surgery, there was no significant difference in PROMs, reoperation rates, or time to reoperation between SBLs, UHL, or WL in patients with central LSS.
