Abstract Purpose In this prospective study, we aim to determine surgical outcomes in patients with lumbar spinal stenosis (LSS) 10 years after surgery. Methods The study population consisted of 96 LSS patients who underwent decompressive surgery, 72 of whom participated in the 10-year follow-up. The patients completed a questionnaire preoperatively and 3 months, 5 years, and 10 years postoperatively. Outcome measures were satisfaction with the surgical outcomes, the Oswestry Disability Index (ODI), the visual analog scale (VAS), the numeric rating scale (NRS-11), and walking ability quantified in meters. Postoperative improvements at 5 and 10 years were analyzed using linear mixed models. Furthermore, comparisons between postoperative time points were made for clinical courses of pain, disability, and walking ability. Results At the 10-year follow-up, 68% of the patients were satisfied with the surgical outcomes. All the measured outcomes showed statistically significant improvement from baseline to the 5- and 10-year follow-up. The mean VAS score was 9.8 mm higher at the 5-year follow-up and 7.8 mm at the 10-year follow-up compared to the 3-month follow-up point. Similarly, the mean ODI was 4.8% higher at the 10-year follow-up compared to the 3-month follow-up point. Conclusion This study reports the clinical course of pain, disability, and walking distance after LSS surgery with the 10-year follow-up. Based on our study results, patients with LSS could expect to have positive effects of their back surgery up to 10 years. However, minor worsening in pain and disability may occur and one-fourth of the patients may need a reoperation during the 10-year follow-up period.

Abstract Purpose Following surgery for lumbar spinal stenosis (LSS) up to 40% of people report persistent walking disability. This study aimed to identify pre-operative factors that are predictive of walking ability post-surgery for LSS. Methods An observational cohort study was conducted using data from the British Spine Registry (2017–2018) of adults (≥ 50 years) with LSS, who underwent ≤ 2 level posterior lumbar decompression. Patients receiving fixation or who had previous lumbar surgery were excluded. Walking ability was assessed by a single item on the Oswestry Disability Index and dichotomised into poor/good outcome. Multivariable regression models were performed. Results 14,485 patients were identified. Pre-operatively 30% patients reported poor walking ability, this decreased to 8% at 12 months follow-up. Predictors associated with poor walking ability at 12 months were: increasing age (≥ 75 years OR 1.54, 95% CI 1.07, 2.18), BMI ≥ 35 kg/m2 (OR 1.52, 95% CI 1.00, 2.30), severity of leg pain (OR 1.10, CI 95% 1.01, 1.21), disability (OR 1.01, 95% CI 1.01, 1.02) and quality of life (OR 0.72, 95% CI 0.56, 0.89). Pre-operative maximum walking distance (OR 1.10, 95% CI 1.05, 1.25) and higher education (OR 0.90, 95% CI 0.80, 0.96) were associated with reduced risk of poor walking ability at 12 months; p < 0.05. Depression, fear of movement and symptom duration were not associated with risk of poor outcome. Conclusion Older age, obesity, greater pre-operative pain and disability and lower quality of life are associated with risk of poor walking ability post-operatively. Greater pre-operative walking and higher education are associated with reduced risk of poor walking ability post-operatively. Patients should be counselled on their risk of poor outcome and considered for rehabilitation so that walking and surgical outcomes may be optimised.

Purpose. The objective of this study was to investigate the preliminary effectiveness of percutaneous endoscopic transforaminal lumbar interbody fusion (PE-TLIF) for the treatment of lumbar spinal stenosis (LSS). Methods. From September 2016 to June 2017, a series of seven patients consisting of six females and one male with an average age of 55.25 years (range 43–77 years) who were diagnosed with LSS were involved in this study. All patients were treated by PE-TLIF. During perioperative and follow-up period, demographic data, operation time, intraoperative blood loss, Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), and modified MacNab criteria were evaluated and perioperative complications were documented. Results. All patients were followed up for more than 12 months, with an average follow-up time of 15 (range 12-21) months. The mean VAS of back pain was 7.43 (range 6-8) preoperatively and 0.86 (range 0-2) at the final follow-up. The mean VAS of leg pain was 6.14 (range 4-9) preoperatively and 0.71 (range 0-1) at the final follow-up. The mean ODI was 53.57% (range 38%-63%) preoperatively and 15.57% (range 5%-26%) at the final follow-up. In three-month follow-up, continuous bone trabeculae bridging between intervertebral bodies was seen in 3 cases, and the remaining 4 cases could identify continuous bone trabeculae bridging at 6-month follow-up, reaching the standard of spinal intervertebral fusion. At the final follow-up, 4 patients were rated as excellent (4/7) and 3 patients were rated as good (3/7) according to the modified MacNab criteria. Conclusions. Our study suggested that percutaneous endoscopic transforaminal lumbar interbody fusion could acquire satisfactory treatment effects for the patients with lumbar spinal stenosis, even for the patient who could not afford general anesthesia.

Object. The authors applied the technique of microendoscopic discectomy to posterior decompression procedures for lumbar spinal stenosis. The purpose of this study was to determine the feasibility of using an endoscopic technique to treat lumbar spinal stenosis and to evaluate the clinical and radiographic results of microendoscopic posterior decompression (MEPD). Methods. Microendoscopic posterior decompression, which involves a unilateral endoscopic approach for bilateral decompression, was performed in 47 patients. Clinical and radiographic/neuroimaging results were evaluated during the follow-up period (minimum duration 1 year). The clinical results were compared with those of the conventional laminotomy. Radiographic instability and the degree of surgical invasion of the facet joints were evaluated. In a control a group of 29 patients open laminotomy was performed. The clinical outcome was evaluated in 44 patients. The mean follow-up duration was 22 months. The mean rate of improvement was 72% based on the Japanese Orthopaedic Association score, and good results were obtained in 38 patients. Although the rate of morbidity decreased in the MEPD group, the incidence of complication was slightly higher. Effective decompression was demonstrated in the majority of the patients by using magnetic resonance imaging. Radiographic instability appeared in one patient postoperatively, and based on computerized tomography scanning, a tendency toward invasion of the facet joint on the approach side was noted. Conclusions. Microendoscopic posterior decompression is a minimally invasive procedure and is as useful as other conventional procedures in treating lumbar spinal stenosis; however, a few technical problems remain to be solved.

ABSTRACT OBJECTIVE To evaluate the efficacy of radicular decompression in lumbar spinal stenosis using a microendoscopic technique. METHODS This was a longitudinal prospective study of 50 patients with a diagnosis of lumbar spinal stenosis who were treated by microendoscopic decompression using an 18-mm METRx tubular retractor according to the METRx technique (Medtronic Sofamor Danek, Memphis, TN). Twenty of the patients had an additional disc prolapse, and a microendoscopic discectomy was associated with decompressive laminectomy. The results were evaluated using the visual analog scale pain score, Oswestry Disability Index score, patient satisfaction questionnaire, and modified Macnab classification. RESULTS The average age of the patients was 56 years; 29 (58%) were men and 21 (42%) were women. The most commonly affected level was L4–L5 (64%). The mean surgical intervention time was 94.3 (± 14.3) minutes. Mean postoperative hospital stay was 3.16 (± 2.3) days. The follow-up time after surgery was 4 years (48 ± 6.6 months; range, 24–72 months). We obtained good or excellent results in 72% of patients, achieving good subjective satisfaction in 68% of the patients. The mean decrease in the Oswestry Disability Index score was 30.23 (± 24.29), the mean decrease in the leg pain visual analog scale score was 6.02 (± 2.57), and the mean decrease in the lumbar pain visual analog scale score was 0.84 (± 2.06). Adjusted mean differences were in all cases statistically significant (P &lt;0.05). CONCLUSION Data indicate that, in our experience, on midterm follow-up, microendoscopic laminectomy decompression is an effective technique for the treatment of lumbar spinal stenosis.

Background To evaluate whether decompression in lumbar spinal stenosis without fusion leads to sufficient improvement of back pain and leg pain and whether re-decompression alone is sufficient for recurrent lumbar spinal stenosis for patients without signs of instability. Material and Methods A successive series of 102 patients with lumbar spinal stenosis (with and without previous lumbar surgery) were treated with decompression alone during a 3-year period. Data on pre- and postoperative back pain and leg pain (numerical rating scale [NRS] scale) were retrospectively collected from questionnaires with a return rate of 65% (n = 66). The complete cohort as well as patients with first-time surgery and re-decompression were analyzed separately. Patients were dichotomized to short-term follow-up (< 100 weeks) and long-term follow-up (> 100 weeks) postsurgery. Results Overall, both back pain (NRS 4.59 postoperative versus 7.89 preoperative; p < 0.0001) and leg pain (NRS 4.09 versus 6.75; p < 0.0001) improved postoperatively. The short-term follow-up subgroup (50%, n = 33) showed a significant reduction in back pain (NRS 4.0 versus 6.88; p < 0.0001) and leg pain (NRS 2.49 versus 6.91: p < 0.0001). Similar results could be observed for the long-term follow-up subgroup (50%, n = 33) with significantly less back pain (NRS 3.94 versus 7.0; p < 0.0001) and leg pain (visual analog scale 3.14 versus 5.39; p < 0.002) postoperatively. Patients with previous decompression surgery benefit significantly regarding back pain (NRS 4.82 versus 7.65; p < 0.0024), especially in the long-term follow-up subgroup (NRS 4.75 versus 7.67; p < 0.0148). There was also a clear trend in favor of leg pain in patients with previous surgery; however, it was not significant. Conclusions Decompression of lumbar spinal stenosis without fusion led to a significant and similar reduction of back pain and leg pain in a short-term and a long-term follow-up group. Patients without previous surgery benefited significantly better, whereas patients with previous decompression benefited regarding back pain, especially for long-term follow-up with a clear trend in favor of leg pain.

Introduction: Spinal stenosis mostly occur in lumbar spine and causes back pain, leg pain & neurogenic claudication. Although conservative treatment is mainstay, decompression with or without fusion (with or without instrumentation) can be considered in non-responsive cases. However, long term outcome of the surgery is controversial. The aim of our study was to analyze the outcome of surgery in lumbar spinal stenosis in terms of post-operative pain and claudication distance.Methods: A prospective analysis of patients who underwent decompression or decompression with fusion (with or without instrumentation), after failure of 3-6 months conservative treatment, for lumbar spinal stenosis were conducted. Only those who were operated and followed up for at least two years were included.Their preop and postop VAS score and walking distance compared.Results: Of 22 cases enrolled in this study, VAS score was improved in 21 patients and walking distance increased. Only one patient complained of increase in pain score at 24 months.Conclusion: Operative management is a good option for selected patients, 21 out of 22 have improved VAS and claudication distance in our study
