BACKGROUND: The Oswestry disability index (ODI) is widely utilized as a patient reported outcome (PRO) tool to assess patients presenting with low back pain (LBP) and following thoracolumbar spine surgery. No primary study has calculated the baseline range of ODI values in the diverse American population. Establishing age-adjusted normative values for ODI in the American population is crucial for assessing the utility of treatment strategies.
OBJECTIVE: The purpose of this study is to describe the baseline range of functional low back disability as measured by the ODI in an American population.
METHODS: Cross-Sectional Observational Study.
METHODS: A total of 1214 participants were recruited from the United States in January 2024 using a combination of the Connect and PrimePanel platforms by CloudResearch to complete a survey administered on a RedCap online database. The survey consisted of 10 demographic questions and the 10 ODI survey questions. The distribution of the survey was designed to obtain approximately 100 respondents in each of the following age groups: 18-29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, 70 to 79, and 80 to 89. The distribution of the sample was similarly designed to match the United States Census racial data with 78.1% White, 13.9% Black, and 7.9% other.
METHODS: Oswestry disability index (ODI).
METHODS: A crowd-sourcing platform called Cloudresearch was used to collect a representative sample of the US population by answering questions of the Oswestry disability questionnaire (ODQ), a 10-question survey.
RESULTS: The final sample size was 797 participants including 386 (48.4%) males and 411 (51.6%) females; 169 participants were excluded that did not complete the survey and an additional 248 were excluded for failing attention check questions. The overall mean ODI score for the combined age groups was 14.35 (95% CI [13.33, 15.37]). The mean ODI scores increased with age, with the highest mean ODI in ages 70 to 79 at 18.0 (95% CI [14.76, 21.24]). Female participants reported higher mean ODI scores than their male counterparts in the 18 to 29 age group (p=.01), 50 to 59 age group (p=.01), and 60 to 69 age group (p=.02). Additionally, a weak positive correlation was found between Body Mass Index (BMI) and ODI scores (r = 0.22, p<.001).
CONCLUSIONS: Our findings demonstrate a clear trend of increased disability with age. This study describes the baseline range of functional low back pain disability in the United States population. By defining these parameters, healthcare professionals can better tailor age and sex-specific interventions to manage disability in the aging US population, ultimately improving patient care and both operative and nonoperative treatment plans for LBP-related thoracolumbar pathology.

Background/Objectives: Anterior spinal fusion for primary thoracolumbar or lumbar (TL/L) adolescent idiopathic scoliosis, AIS, has advantages over posterior fusion, particularly in saving motion segments below the fusion construct. Traditionally, the approach is anterolaterally from the convexity. In adult degenerative scoliosis, the lateral or anterolateral approach may be performed from the traditional or from the concave approach which is less invasive and gives comparable outcomes. The purpose of the present pilot study was to assess the feasibility of the less invasive concave approach for younger AIS patients and compare it to the traditional convex approach over a 5-year follow-up period. Methods: The two cohorts were assessed by comparing pre- to postoperative radiographs, and clinical outcomes for pain, function, self-perception of appearance, and opinion of surgical success were prospectively obtained. Results: Radiographs found that primary TL/L scoliosis significantly improved from 53° to 18° (65%) for both the concave and convex cohorts. Sagittal alignments remained stable and there was no difference between cohorts. Coronal balance improved in both cohorts and sagittal balance was stable for both. Clinically, VAS back pain improved significantly for both cohorts initially and remained improved in the concave group. Leg pain, pain drawing, ODI disability, and VAS appearance scores improved and there was no difference between cohorts. The self-rating of success of the procedure was 100% at early and late follow-up periods. There were no neurological/surgical complications. Conclusions: The concave approach for anterior fusion for TL/L AIS is feasible with comparable radiographic and clinical outcomes to the traditional approach.

UNASSIGNED: Low back pain (LBP) is a common musculoskeletal disorder, that significantly impedes productivity. This study aims to ascertain the risk factors responsible for developing low back pain and the impact on personal workplace service delivery among Anesthetist\'s practicing in Rivers and Bayelsa States of Nigeria.
UNASSIGNED: A cross-sectional survey was conducted, A self-administered questionnaire reflecting the modified Oswestry Disability Index (ODI) was used to detect the risk factors and assess the severity and impact of low back pain on this group of professionals. The prevalence of low back pain was calculated and described by using frequency tables. A multivariate logistic regression model was fitted to identify factors associated with the prevalence of low back pain. Significance was considered at p<0.05 with a 95% confidence interval.
UNASSIGNED: A total of 65 anesthetist\'s responded, giving a response rate of 90%. There were more males (52.3%) than females (47.7%). The majority (69.2%) of those who responded had low back pain, more in females (53.3%) compared to males (46.7%) although not significant. (P=0.994); Majority had moderate pain 58.6%, 22.7% severe and 20.5% mild pain. There was no association between low back pain and age (P=0.130), gender(P=0.994), marital status (P=0.333) and BMI (P=0.164). Bending (P=0.032), lifting (P=0.024), and standing(P=0.016) were predictive variables for low back pain and were statistically significant P<0.05.
UNASSIGNED: Using the Oswestry pain assessment tool for LBP, the estimated prevalence of low back pain was more than fifty percent among the respondents. In this study, frequent bending and twisting, prolonged standing, and lifting were important significant associated factors in the development of LBP among anesthetist\'s.

OBJECTIVE: This study aimed to investigate the impact of sarcopenia and lumbar paraspinal muscle composition (PMC) on patient-reported outcomes (PROs) after lumbar fusion surgery with 12-month follow-up (12 M-FU).
METHODS: A prospective investigation of patients undergoing elective lumbar fusion was conducted. Preoperative MRI-based evaluation of the cross-sectional area (CSA), the functional CSA (fCSA), and the fat infiltration(FI) of the posterior paraspinal muscles (PPM) and the psoas muscle at level L3 was performed. Sarcopenia was defined by the psoas muscle index (PMI) at L3 (CSAPsoas [cm2]/(patients\' height [m])2). PROs included Oswestry Disability Index (ODI), 12-item Short Form Healthy Survey with Physical (PCS-12) and Mental Component Scores (MCS-12) and Numerical Rating Scale back and leg (NRS-L) pain before surgery and 12 months postoperatively. Univariate and multivariable regression determined associations among sarcopenia, PMC and PROs.
RESULTS: 135 patients (52.6% female, 62.1 years, BMI 29.1 kg/m2) were analyzed. The univariate analysis demonstrated that a higher FI (PPM) was associated with worse ODI outcomes at 12 M-FU in males. Sarcopenia (PMI) and higher FI (PPM) were associated with worse ODI and MCS-12 at 12 M-FU in females. Sarcopenia and higher FI of the PPM are associated with worse PCS-12 and more leg pain in females. In the multivariable analysis, a higher preoperative FI of the PPM (β = 0.442; p = 0.012) and lower FI of the psoas (β = -0.439; p = 0.029) were associated with a worse ODI at 12 M-FU after adjusting for covariates.
CONCLUSIONS: Preoperative FI of the psoas and the PPM are associated with worse ODI outcomes one year after lumbar fusion. Sarcopenia is associated with worse ODI, PCS-12 and NRS-L in females, but not males. Considering sex differences, PMI and FI of the PPM might be used to counsel patients on their expectations for health-related quality of life after lumbar fusion.

Background and Objectives: Endoscopic epidural neuroplasty (EEN) facilitates adhesiolysis through direct epiduroscopic visualization, offering more precise neural decompression than that exhibited by percutaneous epidural neuroplasty (PEN). We aimed to compare the effects of EEN and PEN for 6 months after treatment with lower back and radicular pain in patients. Methods: This retrospective study compared the visual analog scale (VAS) and Oswestry disability index (ODI) scores in patients with low back and radicular pain who underwent EEN or PEN with a steering catheter. The medical records of 107 patients were analyzed, with 73 and 34 undergoing EEN and PEN, respectively. Results: The VAS and ODI scores decreased at all time points after EEN and PEN. VAS and ODI scores decreased more in the EEN group than those in the PEN group at 1 day and 1- and 6-months post-procedure, indicating superior pain relief for both lower back and radicular pain through EEN. Conclusions: EEN is a superior treatment of pain control than PEN in lower back and radicular pain patients.

UNASSIGNED: Chronic low back pain (CLBP) imposes considerable financial and social burden with poor response to medical and surgical treatments. Alternatively, acupuncture and venesection(Fasd) are traditionally used to alleviate nociceptive and musculoskeletal pains. This study aimed to evaluate the effectiveness and the safety of acupuncture and venesection on CLBP and patient functionality.
UNASSIGNED: The current study was a single-blinded, randomized clinical trial with balanced allocation, conducted in the Department of Physical Medicine & Rehabilitation Medicine, in 2022. One hundred five CLBP patients who had no back pain-attributable structural or major diseases were randomly allocated into three parallel arms and received either physical therapy (PTG), acupuncture (APG), or venesection (VSG). Pain severity and functional aspects were evaluated using the visual analogue scale (VAS) and Oswestry disability index (ODI) during the study. VAS and ODI scores were defined as the primary outcomes.
UNASSIGNED: Ninety-five patients were reviewed in the final analysis (PTG=33, APG=30, VSG=31). Demographic data showed equal group distribution. Statistical analysis showed all procedures had reduced VAS score immediately after the first session, after the last session, and after follow-up; however, APG and VSG values were significantly lower (P<0.05). Pain reduction results in follow-up period were more sustainable in APG and VSG as compared to PTG (P<0.01). ODI results revealed global improvement after the last session of the treatment in all groups, while APG had more significant results (P<0.05). During the follow-up period, ODI still tended to decrease in VSG, non-significantly increased in APG, and significantly increased in PTG. Only two patients reported fainting after receiving venesection.
UNASSIGNED: Considering the pain and functional scores, both acupuncture and venesection can reproduce reliable results. Acupuncture and venesection both have sustained effects on pain and daily function of the patients even after treatment termination, while physical therapy had more relapse in pain and functional limitations.

BACKGROUND: Academic orthopedic journals and specialty societies emphasize the importance of two-year follow-up for patient-reported outcome measures (PROMS) after spine surgery, but there are limited data evaluating the appropriate length of follow-up.
OBJECTIVE: To determine whether PROMs, as measured by the Oswestry Disability Index (ODI), would change significantly after 2-months postoperatively after lumbar decompression surgery for disc herniation or spinal stenosis.
METHODS: Retrospective analysis of prospectively and consecutively enrolled patients undergoing lumbar decompression surgery between 2020 and 2021 from a single surgeon spine registry.
METHODS: One hundred sixty-nine patients.
METHODS: ODI, achievement of minimum clinically important difference (MCID), revisions.
METHODS: Patients without a preoperative baseline score were excluded. Completion of the ODI questionnaire was assessed at the follow-up points. The median ODI was compared at time baseline, 2-month, 1-year and 2-year follow-up. Risk of reoperation was assessed with receiver operating characteristic (ROC) analysis to identify at-risk ODI thresholds of requiring reoperation.
RESULTS: Median ODI significantly improved at all time points compared to baseline (median baseline ODI: 40; 2-month ODI: 16, p=.001; 1-year ODI: 11.1, p=.001; 2-year ODI: 8, p=.001). Posthoc analysis demonstrated no difference between 2-months, 1-year and 2-year postoperative ODI (p=.9, p=.468, p=.606). The MCID was met in 87.9% of patients at 2 months, 80.7% at 1 year, and 87.3% at 2 years postoperatively. Twelve patients (7.7%) underwent revision surgery between 2 months and 2 years after the index surgery (median time to revision: 5.6 months). ROC curve analysis demonstrated that an ODI score ≥24 points at 2-months yielded a sensitivity of 85.7% and a specificity of 71.8% for predicting revision after lumbar decompression (AUC=0.758; 95% CI: 0.613-0.903). The Youden optimal threshold value of ≥24 points at 2-month postop ODI yielded an odd ratio (OR) for revision of 15.3 (CI: 1.8-131.8; p=.004). The positive predictive value (PPV) and negative predictive value (NPV) were 15.4% and 98.8%, respectively.
CONCLUSIONS: Two-year clinical follow-up may not be necessary for future peer-reviewed lumbar decompression surgery studies given that ODI plateaus at 8 weeks. Patients with a score ≥24 points at 2-months postoperatively have a higher risk of requiring a second surgery within the first 2 years and warrant continued follow-up.

UNASSIGNED: This study intended to evaluate the effects of Low-Level Laser Therapy (LLLT) on Failed Back Surgery Syndrome (FBSS). FBSS refers to symptoms and disabilities which remain or occur after lumbar spinal surgery. Prevalent treatments for FBSS are based mostly on conservative management while LLLT has gained significant interest in the treatment of a wide variety of musculoskeletal disorders.
UNASSIGNED: In the present study, the authors included 50 individuals with FBSS. Target points were determined by an ultrasonic study including bilateral L2-L3 through L5-S1 facet joints, sacroiliac joints, and the region immediately above bilateral supra crestal iliac bones representing cluneal nerves. LLLT was performed three times a week for 3 weeks. A near-infrared laser (wavelength 808 nm, power 500 mw) was used in continuous mode for laser therapy sessions. The Numeric Rating Scale (NRS) and Oswestry Disability Index (ODI) were registered before treatment and after last treatment session, 1 month and 6 months later, respectively.
UNASSIGNED: NRS and ODI were significantly improved after treatment, as well as therapeutic effects, after 1 month and 6 months were also evident and comparison of the NRS and ODI showed significant difference.
UNASSIGNED: LLLT has a positive impact on pain and disability in patients with FBSS.

UNASSIGNED: To evaluate the role of lumbar sacralization (LS) on the surgical outcomes of L4-L5 microdiscectomy.
UNASSIGNED: This prospective cohort study was conducted in a university referral hospital. The patients with L4-L5 disc herniation and eligible for microdiscectomy were enrolled and allocated in G1 (with LS) and G2 (no LS). After the L4-L5 microdiscectomy patients were followed, clinical and radiological parameters were collected to investigate the influence on the outcomes. Recurrence, low back outcome score (LBOS), and the Oswestry disability index (ODI) were defined as main outcomes.
UNASSIGNED: Two hundred and forty patients (n = 120, each), were reviewed in the final analysis. There was no difference between groups regarding baseline characteristics. Postoperative radicular and back pain was more severe in LS(P < 0.05). Univariate analysis showed recurrence was significantly higher in LS with a direct correlation with postoperative back pain persistence and low LBOS (p = 0.001). Age had a negative impact on G2 recurrence(p = 0.008). LS had a negative impact on LBOS and ODI scores. Postoperative radicular pain and higher lumbar lordosis were associated with a higher disability (ODI) index.
UNASSIGNED: L4-L5 microdiscectomy in patients with lumbar sacralization was associated with higher recurrence rates, worse ODI and LBOS scores, persistent postoperative axial back pain, and radicular pain. Postoperative axial back pain and poor LBOS results could effectively predict a higher recurrence rate following L4-L5 microdiscectomy in lumbar sacralization.

UNASSIGNED: retrospective cohort study of prospectively collected data.
UNASSIGNED: The treatment guidelines for thoracolumbar spinal fractures are controversial although minimally invasive surgery (MIS) is a popular alternative to the traditional open approach (TOA). Limited data exists about outcomes after MIS fracture treatment. The main aim of our study was to evaluate self-reported disability, health-related quality of life, pain, and satisfaction after MIS compared with TOA.
UNASSIGNED: Of 173 patients operated from 2014 to 2018, 64.7% patients completed the Oswestry Disability Index (ODI), the EQ-5D-5L, and a tailored clinical follow-up questionnaire on employment status, pain, activity level, and satisfaction with treatment.
UNASSIGNED: Of the 112 patients, 34 had MIS and 78 had TOA. Mean follow-up was 56 months. The two groups were comparable on demographic variables apart from mean age - MIS group was 10 years older. The MIS group had better ODI scores (p = 0.046), but the groups were similar regarding return to work and disability retirement. The EQ-5D-5L index for the MIS were very close (mean -0.033, median +0.049) to the Danish population score, while the TOA showed a greater deviation (mean - 0.125, median -0.040). The MIS used less pain medication than the TOA. Both groups were similarly satisfied with treatment results.
UNASSIGNED: Our data indicates that MIS surgery for thoracolumbar spinal fractures can achieve acceptable self-reported outcomes in terms of disability, health-related quality of life, pain, and satisfaction with treatment. However, a randomized controlled trial is needed to determine whether the MIS approach is superior to TOA.
