Abstract Introduction The aim of this study was to compare clinical results of bilateral decompression and laminotomy and contralateral laminotomy following discectomy from the same side in patients who have far lateral disk herniation and lumbar spinal stenosis at the same level. Materials and Methods Twenty-four patients with far lateral disk herniation have been divided into two groups: group 1 (n = 14), those who have been through bilateral canal decompression with far lateral discectomy and ipsilateral approach, and group 2 (n = 10), those who have been through far lateral discectomy and bilateral decompression with unilateral approach from contralateral side. Early postoperative, 1st month, and 12th month back and leg pain Visual Analogue Scale (VAS) scores of the patients have been retrospectively evaluated. Results There is no significant difference between 1st month back and leg pain VAS scores of the groups. But 12th month back and leg pain VAS scores of group 1 are significantly higher than 1st month VAS scores. Also, 12th month back and leg pain VAS scores of group 1 are significantly higher than group 1. In the scanning carried out when the complaints of eight patients in group 1 continued, pars interarticularis fracture has been observed on the side where the surgery has been performed (57.1%). Six of these eight patients have been through stabilization surgery (42.8%). Conclusion Long-term postoperative results are better in cases who have been performed bilateral decompression with unilateral approach from contralateral side with median incision following paramedian incision discectomy in patients with far lateral disk herniation and spinal stenosis.

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.

We investigated the efficacy of pregabalin (PGB) for neuropathic leg pain in lumbar spinal stenosis (LSS) patients with disturbed activities of daily living (ADL)/quality of life (QOL) in a prospective observational study. Subjects were a total of 104 LSS patients with neuropathic pain (NeP) in leg and neurological intermittent claudication (IMC) refractory to nonsteroidal anti-inflammatory drugs (NSAIDs) for at least a month. NeP was identified using screening tool, Pain DETECT questionnaire. Visual analog scale (VAS) scores and responses to the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) were assessed before and 6 weeks after PGB treatment initiation. Changes in IMC distance and adverse events were also recorded. PGB significantly improved their VAS scores for pain and sleep quality (P<0.001). With respect to JOABPEQ, significant improvements were observed with regard to the following dimensions: pain-related disorders (P<0.01), lumbar spine dysfunction (P=0.031), gait disturbance (P=0.028), and psychological disorders (P=0.014). The IMC distance showed an improvement tendency after PGB treatment, albeit with no significance (P=0.063). Minor adverse events such as dizziness were observed. PGB can be effective for neuropathic leg pain refractory to NSAIDs in LSS patients, resulting in not only pain control but also improving lower back pain-related ADL/QOL scores.

Study Design: Retrospective review of a single institution. Objective: To determine if resting leg pain level is a predictor of success for indirect decompression in the setting of lumbar spinal stenosis, with lower levels of rest pain correlating with greater likelihood of successful indirect decompression. Methods: Reviewed anterior or lateral lumbar interbody fusions from T12 to L5-S1 patients with a posterior-based pedicle screw-rod construct. Patients were separated into 2 groups based on a preoperative response to Oswestry Disability Index (ODI) Question 7 regarding level of pain at rest in the supine position. Responses of 0 to 2 (minimal rest pain) were group 1 (n = 54) and responses of 3 to 5 (significant rest pain) were group 2 (n = 16). Results: Preoperative difference was detected between groups 1 and 2, in ODI (38 vs 63, P < .001) and Numeric Rating Scale (NRS) back (6.8 vs 7.9, P = .023). Three-month NRS leg and back scores were significantly lower in group 1 (leg, 1.9 vs 4.8, P < .001; back, 3.5 vs 6.4, P = .001). A significant difference was further noted in the percentage decrease in NRS leg and back scores from pre- to 3 months postoperatively between groups 1 and 2 (leg, 68.4% vs 22.7%, P < .001; back, 40.0% vs 7.4%, P = .012). Group 1 reached minimal clinically important difference for leg pain more often than group 2 (83.3% vs 43.8%, P = .001). Conclusion: Preoperative assessment of rest pain level in the supine position has a significant association with reduction in NRS leg and back scores in patients undergoing indirect decompression for lumbar spinal stenosis. This tool may successfully indicate which patients will be candidates for indirect decompression with interbody fusion from an anterior or lateral approach.

OBJECT This prospective cohort study was designed to determine the influence of depressive symptoms on patient expectations and the clinical outcomes of the surgical management of lumbar spinal stenosis. METHODS Patients with an age > 45 years, a diagnosis of lumbar spinal stenosis at one level, and an indication for decompressive surgery were included in this study. Data for all of the following parameters were recorded: age, sex, highest level of education, and employment status. Depression symptoms (Beck Depression Inventory), disability (Oswestry Disability Index), and back and leg pain (visual analog scale) were assessed before surgery and at 12 months thereafter. The reasons for surgery and patient expectations (North American Spine Society lumbar spine questionnaire) were noted before surgery. The global effectiveness of surgery (Likert scale) was assessed at the 1-year follow-up. RESULTS Fifty-eight patients were divided into two groups based on the presence (Group 1) or absence (Group 2) of depressive symptoms preoperatively; each group comprised 29 patients. Demographic data were similar in both groups before surgery. The main reason to undergo surgery was “fear of a worse situation” in 34% of the patients in Group 1 and “to reduce pain” in 24% of the patients in Group 2. The most prevalent expectation was to improve my social life and my mental health in both groups. Surgery had a relieving effect on the depressive symptoms in 14 patients (48%). Thus, in the postoperative period, the number of patients who were free of depressive symptoms was 43 compared with the 15 who were depressed (p = 0.001). The 15 patients with persistent depression symptoms after surgery had a worse clinical outcome compared with the 43 patients free of depression symptoms at the 1-year follow-up in terms of severe back pain (20% vs 0%, respectively), severe leg pain (40% vs 2.3%, respectively), and severe disability (53% vs 9.3%, respectively). Only 33% of patients with persistent depression symptoms after surgery chose the option “surgery helped a lot” compared with 76% of patients without depression symptoms. Moreover, in terms of expectations regarding improvement in back pain, leg pain, walking capacity, independence, physical duties, and social activities, fewer patients were “completely satisfied” in the group with persistent depression symptoms after surgery. CONCLUSIONS Surgery for spinal stenosis had a relieving effect on preoperative depression symptoms at the 1-year follow-up. The persistence of depressive symptoms after surgery correlated with a worse clinical outcome and a higher rate of unmet expectations. Screening measures to detect and treat depression symptoms in the perioperative period could lead to better clinical results and increased patient satisfaction.

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: 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. Key words: Vitamin D, lumbar spinal stenosis, pain, bone mineral density
