✓ Lumbar spinal stenosis is a common problem in elderly patients. In its more advanced forms, it typically causes intractable leg pain, but many patients also manifest varying degrees of bladder dysfunction. The goal of lumbar decompressive laminectomy is relief of leg pain and paresthesias, yet some patients also achieve improvement in bladder function. This study prospectively investigated patients with lumbar spinal stenosis to determine whether laminectomy had any effect on urological function. Of the 20 patients in the study, 10 were men and 10 women (average age 70.9 years). All patients had severe lumbar stenosis affecting between two and four spinal segments, and all reported some degree of bladder dysfunction. Cystoscopy and urodynamic testing were completed preoperatively. A standard decompressive laminectomy was performed over the appropriate number of spinal segments. Urodynamic studies were repeated at 2 and 6 months postoperatively. At the 6-month follow-up review, bladder function was subjectively improved in 12 patients (60%) and unchanged in eight (40%). Postvoiding residual urine volume was the urodynamic factor most likely to be improved by laminectomy. In nine patients (45%), baseline postvoiding residual urine volume was elevated and all nine had improvement postoperatively. In the remaining 11 patients (55%), this urine volume was normal before and after surgery. Maximum urine flow rates also improved, but the results of cytometrography and electromyography, urine flow pattern, and bladder capacity were unchanged postoperatively. Cystoscopy detected previously undiagnosed malignancy of the lower urinary tract in two patients (10%). It is concluded that lumbar decompressive laminectomy can have a beneficial effect on bladder function in a significant number of patients with advanced lumbar spinal stenosis.

Introduction: This study was aimed at comparing outcomes of minimally invasive (MIS) versus OPEN surgery for lumbar spinal stenosis (LSS) in patients with diabetes. Methodology: This retrospective cohort study included patients with diabetes who underwent spinal decompression alone or with fusion for LSS within the Canadian Spine Outcomes and Research Network (CSORN) database. Outcomes of MIS and OPEN approaches were compared for two cohorts: (i) patients with diabetes who underwent decompression alone (N = 116; MIS, n = 58, OPEN, n = 58) and (ii) patients with diabetes who underwent decompression with fusion (N = 108; MIS, n = 54, OPEN, n = 54). Mixed measures analyses of covariance compared modified Oswestry Disability Index (mODI) and back and leg pain at one-year post operation. The number of patients meeting minimum clinically important difference (MCID) or minimum pain/disability at one year were compared. Result: MIS approaches had less blood loss (decompression alone difference 99.66 mL, p = 0.002; with fusion difference 244.23, p < 0.001) and shorter LOS (decompression alone difference 1.15 days, p = 0.008; with fusion difference 1.23 days, p = 0.026). MIS compared to OPEN decompression with fusion had less patients experience an adverse event (difference, 13 patients, p = 0.007). The MIS decompression with fusion group had lower one-year mODI (difference, 14.25, p < 0.001) and back pain (difference, 1.64, p = 0.002) compared to OPEN. More patients in the MIS decompression with fusion group exceeded MCID at one year for mODI (MIS 75.9% vs OPEN 53.7%, p = 0.028) and back pain (MIS 85.2% vs OPEN 70.4%, p = 0.017). Conclusion: MIS approaches were associated with more favorable outcomes for patients with diabetes undergoing decompression with fusion for LSS.

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.

Background: Our hypothesis was that by identifying certain preoperative predictive factors, we could favorably impact clinical outcomes in patients undergoing decompressive surgery for lumbar spinal stenosis (LSS). Methods: In this retrospective study, there were 65 patients (2016–2018) with symptomatic LSS who underwent decompressive laminectomy without fusion. Their clinical outcomes were assessed utilizing the Oswestry Disability Index (ODI). Multiple preoperative variables were studied to determine which ones would help predict improved outcomes: gender, age, body mass index (BMI), general/neurological examination, smoking, and drug therapies (anxiolytics and/or antidepressants). Results: All patients demonstrated statistically significant improvement on the ODI. Multivariate analysis revealed that those with higher preoperative BMI had significantly lower ODI on 1-year follow-up examinations, reflecting poorer outcomes. Postoperatively, 44 patients (67%) exhibited lower utilization of anxiolytic medications, 52 patients (80%) showed reduced use of antidepressant drugs, and pain medications utilization was reduced in 33 patients (50%). Conclusion: Decompressive laminectomy without fusion effectively managed LSS. It reduced patients’ use of pain, anxiety, and antidepressant medications. In addition, we found that increased preoperative BMIs contributed to poorer postoperative outcomes (e.g., ODI values).

Background: The symptom severity of back pain/leg pain is not correlated with the severity of degenerative changes and canal stenosis in lumbar stenosis. Considering the individual pain sensitivity might play an important role in pain perception, this discordance between the radiologic findings and clinical symptoms in degenerative lumbar stenosis might originate from the individual difference of pain sensitivity for back pain and/or leg pain. Objective: To determine the relationship among the clinical symptoms, radiologic findings, and the individual pain sensitivity in the patients with degenerative lumbar spinal stenosis. Study Design: Retrospective analysis of prospectively collected data. Setting: A spine center in the department of orthopedic surgery. Methods: In 94 patients who had chronic back pain and/or leg pain caused by degenerative lumbar spinal stenosis, a medical history, a physical examination, and completion of a series of questionnaires, including pain sensitivity questionnaire (PSQ) [total PSQ and PSQ-minor], Oswestry Disability Index (ODI), Visual Analog Pain Scale (VAS) for back pain, and Short Form36 (SF-36) were recorded on the first visit. Radiologic analysis was performed using the MRI findings. The grading of canal stenosis was based on the method by Schizas, and the degree of disc degeneration was graded from T2-weighted images with the Pfirrmann classification. The correlations among variables were statistically analyzed. Results: Total PSQ and PSQ-minor were not dependent on the grade of canal stenosis after gender adjustment. VAS for leg pain and back pain was highly associated with the total PSQ and the PSQ-minor. Total PSQ and PSQ-minor were also significantly associated with ODI. Among SF36 scales, the PSQ minor had significant correlations with SF-36 such as bodily pain (BP), Roleemotional (RE), and Mental Component Summary (MCS) after control of confounding variables such as body mass index (BMI), age, and the grade of canal stenosis/disc degeneration. Total PSQ was significantly associated with the SF-36 RP, BP, and RE. Furthermore, after adjustment for gender and pain sensitivity, there was no significant association between the grade of canal stenosis and VAS for back pain/leg pain and ODI, and no correlation was found between the grade of disc degeneration and VAS for back pain/leg pain and ODI, either. Limitations: The multiple lesions of canal stenosis and/or disc degeneration and the grade of facet degeneration were not considered as a variable. Conclusion: The current study suggests that the pain sensitivity could be a determining factor for symptom severity in the degenerative spinal disease.

Background: Patients with lumbar spinal stenosis (LSS) are at a great risk of a fall and fracture, which vitamin D protects against. Vitamin D deficiency is expected to be highly prevalent in LSS patient, and pain is thought to have a profound effect on vitamin D status by limiting activity and sunlight exposure. Objective: To identify the prevalence of vitamin D deficiency (serum 25-hydroxyvitamin D [25-OHD] < 20ng/mL) and its relationship with pain. Study Design: Nonblinded, cross-sectional clinical study. Setting: University-based outpatient clinic of the Department of Orthopedic Surgery, Yonsei University College of Medicine, Korea. Methods: Consecutive patients who visited the orthopedic outpatient clinic for chronic low back pain and leg pain and were diagnosed as LSS between May 2012 and October 2012 were included. Pain was categorized into 4 groups based on location and severity: 1) mild to moderate back or leg pain; 2) severe back pain; 3) severe leg pain; and 4) severe back and leg pain. Covariates for vitamin D deficiency included age, sex, body mass index, level of education, medical history, season, region of residence, sunlight exposure score and functional disability. 25-OHD level was measured by radioimmunoassay, and bone metabolic status including bone mineral density and bone turnover markers was also measured. Multivariable logistic regression modeling was used to adjust all risk estimates for covariates. Results: The study had 350 patients enrolled. Mean serum 25-OHD level was 15.9 ± 7.1 ng/mL (range, 2.5 ~ 36.6). of the 350 patients, 260 patients out of 350 (74.3%) were vitamin D deficient. Univariate logistic regression analysis showed a significantly higher prevalence of vitamin D deficiency in the following patients: 1) medical comorbidity; 2) urban residence rather than rural; 3) lower score for sunlight exposure; and 4) severe leg pain, or severe back and leg pain rather than mild to moderate pain. Pain category was significantly associated with lower sunlight exposure; however, the association between pain category and vitamin D deficiency remained significant even after adjustment for the sunlight exposure. Furthermore, severe back pain, and severe back and leg pain were also associated with higher incidence of osteoporosis and higher level of bone resorption marker (serum CTx). Limitations: The limitation of our study is that due to its cross-sectional design, causal relationships between pain and vitamin D deficiency could not be established. Conclusion: Vitamin D deficiency was highly prevalent in LSS patients (74.3%), and severe pain was associated with higher prevalence of vitamin D deficiency and osteoporosis which could be potential risk factors or a fall and fracture. As evidenced by the present study, assessment of serum 25-OHD and bone mineral density are recommended in LSS patients with severe pain, and active treatment combining vitamin D, calcium, or bisphosphonate should be considered according to the status of the bone metabolism.

Abstract Background: To analyze the relational factors influencing the formation of cauda equina redundant nerve roots (RNRs) of the lumbar spinal stenosis.Methods: A retrospective study of 116 patients with lumbar spinal stenosis were treated in our department from January 2016 to June 2019. Magnetic resonance imaging (MRI) was performed to observe the shape and morphology of the redundant nerve roots of the cauda equina.We divided patient into (RNRs) group and non-RNRs( NRNRs) group based on the presence or absence of RNRs on sagittal T2-weighted MR. We analyzed the demographic characteristics, preoperative back pain visual analogue scale (VAS) scores ,preoperative leg pain VAS scores, and preoperative Oswestry disability index(ODI) scores, and also analyzed the rate of spondylolisthesis and ligamentum flavum hypertrophy. Simultaneously,the inter-vertebral height, intervertebral foramen height, inter-vertebral height +vertebral height, median sagittal diameter at the inter-vertebral space level(DIW-MSD),median sagittal diameter at the pedicel level(DV-MSD),ROM of the stenotic segment, were statistically analyzed for clinical and radiological significance.Results : Of a total 116 total patients,there were no statistically significant differences in either gender [RNRs group (n = 42, 18/24 female) and NRNR group (n = 74, 38/36 female)], age, BMI index, preoperative back pain VAS score , preoperative leg pain VAS score and preoperative ODI score(p> 0.05);however, there were statistically significant differences regard to the duration of symptoms and the rate of spondylolisthesis and ligamentum flavum hypertrophy (p<0.05);the inter-vertebral height,Intervertebral foramen height, inter-vertebral height+vertebral height, DIW-MSD ,ROM of the stenotic segment were also significantly different between the group (p<0.05).Conclusions:The inter-vertebral height, inter-vertebral foramen height, inter-vertebral height + vertebral height, DIW-MSD and ROM of the stenotic segment were the crucial factors related to RNRs in lumbar spinal stenosis.

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
