AI Article Synopsis
- The study used mixed methods to analyze the Oswestry Disability Index (ODI) scores in people who had lumbar spine surgery versus a non-surgical group, aiming to establish threshold values for better decision-making in surgeries.
- A total of 557 patients who had surgery were compared to 797 individuals from the general U.S. population, finding that surgical patients had a significantly higher mean ODI score of 34.7 compared to 14.4 in the general population.
- The research identified a key ODI threshold of 16.5 that can help in assessing the need for spinal surgery, emphasizing that ODI scores should be part of a broader clinical evaluation rather than the sole factor in surgical decisions.
Article Abstract
Study Design: A mixed-methods investigation with both retrospective and prospective components.
Objective: Determine the mean Oswestry Disability Index (ODI) scores for individuals who underwent surgical intervention compared to a non-surgical population and identify threshold values that distinguish between these groups.
Summary Of Background Data: The Oswestry Disability Index (ODI) quantifies disability in patients with low back pain and commonly serves as a significant determinant in lumbar spine pathology and surgical outcomes. An empirically established ODI threshold can aid in optimizing surgical decision-making processes.
Methods: This study retrospectively analyzed 557 patients who consulted with a spine surgeon and subsequently underwent lumbar spine surgery from 2019 to 2023. Additionally, ODI scores were surveyed from 797 individuals in the general American population using the CloudResearch Connect platform, with participants matched for age and sex according to US census data. Mean ODI scores stratified by age group and sex were calculated for each cohort. Receiver Operating Characteristic (ROC) analysis was utilized to ascertain ODI cutoff values for different demographics.
Results: The retrospective cohort demonstrated a higher disability level with an overall mean ODI of 34.7 (95% CI [33.1, 36.2]) for ages 18-89. In contrast, the general population surveyed had a mean ODI of 14.4 (95% CI [13.3, 15.4]). An ROC-derived ODI threshold of 16.5 within the comprehensive age group of 18-89 exhibited a sensitivity of 0.84 and a specificity of 0.68.
Conclusion: The ODI values identified in this study offer benchmarks that can assist in the evaluation process for spine surgery. These findings highlight the importance of considering ODI scores as part of a comprehensive clinical evaluation, rather than as standalone indicators for surgical intervention. Further prospective validation of these findings and their integration into clinical practice is recommended for future research.

Purpose: This study aims to investigate the influence of multifidus muscle fat infiltration on clinical outcomes in lumbar disc herniation (LDH) undergoing percutaneous endoscopic lumbar discectomy (PELD).
Methods: A retrospective analysis was conducted on 224 patients who underwent lateral PELD, with complete one-year follow-up data. Patients were divided into two groups based on preoperative MRI evaluation of L4 multifidus muscle fat infiltration: a mild group (< 25%) and a severe group (≥ 25%).

The aim of this research was to conduct randomized trials assessing the extent of cement diffusion following robot-assisted percutaneous vertebroplasty (R-PVP) for osteoporotic vertebral compression fractures (OVCF). A total of 96 OVCF patients meeting the inclusion criteria and admitted between January 2023 and November 2023 were included in the study. Among them, 48 patients were assigned to the robotic-assisted PVP group (R-PVP group) and 48 patients were assigned to the traditional PVP group (PVP group).

Aim: Minimally-invasive spinal surgery is increasingly being adopted worldwide. In this study, we evaluated the postoperative magnetic resonance imaging (MRI) findings and clinical outcomes of patients who underwent full endoscopic lumbar disk surgery.
Methods: Preoperative and postoperative 3rd and 6th month MRI features, visual analog scale (VAS) score, Oswestry Disability Index (ODI), and clinical features of patients who underwent percutaneous endoscopic lumbar discectomy between August 2009 and January 2012 were retrospectively analyzed.
