Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have transformed the management of T2DM and obesity, offering potent weight loss and glycemic benefits. Moreover, preclinical studies suggest anti-inflammatory and anti-oxidative properties of GLP-1 RAs could theoretically slow the progression of LDD. Despite these promising indications, long-term clinical data on whether GLP-1 RAs truly mitigate LDD risk and related interventions is lacking. This study harnesses a large national database to elucidate the complex interplay between GLP-1 RA use, metabolic disease, and LDD outcomes over five years.</div></div><div><h3>PURPOSE</h3><div>We aimed to clarify the impact of GLP-1 RA use on the 5-year incidence of LDD, rates of lumbar fusion, and need for spinal injections in patients with varying obesity and T2DM statuses. Given the therapeutic potential of GLP-1 RAs in treating metabolic risk factors for LDD, we hypothesized that patients prescribed GLP-1 RAs would exhibit lower progression to LDD. Our findings challenge this assumption and offer new insights on the interplay between metabolic management and spine health.</div></div><div><h3>STUDY DESIGN/SETTING</h3><div>We conducted a retrospective cohort study using the TriNetX US collaborative network—one of the largest real-world healthcare databases, capturing deidentified electronic medical records from diverse hospital systems.

Specifically, we compared GLP-1 RA users to nonusers in: Obese patients with T2DM, Obese patients without T2DM, Nonobese patients with T2M. To broaden the investigation, we also evaluated a random matched sample representing the general patient population without a history of LDD.

Contemporary stereotactic body radiotherapy (SBRT) may circumvent these limitations by delivering higher doses in fewer fractions to smaller, well-defined targets, improving local control and reducing treatment-related toxicities.

Lordotic lumbar interbody fusion cages may aid in this restoration through the use of lumbar total disc replacement (TDR) implants, which come in a variety of heights and endplate angles. There is very little information available on the impact of TDR on sagittal alignment.</div></div><div><h3>PURPOSE</h3><div>The purpose of this study was to compare pre- to post-TDR sagittal alignment based on full-body imaging.</div></div><div><h3>STUDY DESIGN/SETTING</h3><div>Retrospective cohort study.</div></div><div><h3>PATIENT SAMPLE</h3><div>The study included a series of 132 patients (mean age 41.1 years; mean BMI 27.7 kg/m2, 69.7% male) who had a full body EOS scan before TDR and at their first post-operative office visit. All patients were treated for symptomatic disc degeneration unresponsive to at least 6 months of nonoperative care.</div></div><div><h3>OUTCOME MEASURES</h3><div>Multiple radiographic measurements were made related to spinal alignment including pelvic incidence, sacral slope, pelvic obliquity, coronal balance, spino-sacral angle, thoracic kyphosis, and lumbar lordosis. The disc height and angulation were also measure for each lumbar level.</div></div><div><h3>METHODS</h3><div>Data were collected by chart review which included general descriptors and surgery data. Radiographic measurements were completed on SterEOS for both pelvic and postural parameters. Additionally, L1-S1 segmental disc angles and disc heights were measured using PACS applied to the EOS images.</div></div><div><h3>RESULTS</h3><div>There were 178 TDR devices implanted, with most operations at 1-level (n=89). There were statistically significant changes in 3 sagittal alignment measurements after TDR surgery: sacral slope, sagittal pelvic tilt, and spino-sacral angle. Both sacral slope and spino-sacral demonstrated an increase while sagittal pelvic tilt decreased. There was a statistically significant increase and decrease in disc angulation of operated levels and nonoperated levels, respectively. There was a statistically significant increase in disc height at the operated level(s) as well as the nonoperated levels, though this was not clinically relevant.</div></div><div><h3>CONCLUSIONS</h3><div>The findings demonstrate a significant rotation of the pelvis backwards, increased spino-sacral angulation, and disc space angulation, supporting lumbar TDR’s ability to successfully improve the upright standing position in the sagittal plane. Long-term follow-up will be necessary to determine if these early changes are maintained.</div></div><div><h3>FDA Device/Drug Status</h3><div>This abstract does not discuss or include any applicable devices or drugs.</div></div>","PeriodicalId":49484,"journal":{"name":"Spine Journal","volume":"25 11","pages":"Pages S6-S7"},"PeriodicalIF":4.7,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nicotine has been closely linked to adverse surgical outcomes, particularly pseudarthrosis, due to its vascular and bone-healing impacts. While tobacco nicotine dependence is well-studied, nontobacco nicotine products (eg, e-cigarettes, vaping devices) are increasingly popular and perceived by many as safer alternatives. However, their physiological impact—encompassing vasoconstriction, immune modulation, and potential toxicity from added chemicals—may similarly predispose patients to surgical complications. This study examines whether nontobacco nicotine dependence (NTND) increases the risk of short- and long-term complications following lumbar fusion surgery.</div></div><div><h3>PURPOSE</h3><div>To evaluate the relationship between preoperative non-tobacco nicotine dependence and postoperative complications in lumbar fusion patients within 90 days and up to 2 years post-surgery.
