In 904 CSM surgery patients, about 45% achieved substantial neck disability improvement at 24 months; worse baseline neck pain, anterior approach, and higher socioeconomic status predicted benefit, while fusion ending at C7 and government insurance predicted less.
Osteoporosis Screening Gaps Among Patients Undergoing Lumbar Fusion Surgery.
In a 46,104-patient TriNetX cohort, only 4.5% of men and 15.6% of women had preoperative DEXA before lumbar fusion, and few diagnosed patients received treatment, showing major screening and treatment gaps.
In 172 matched L4-5 standalone lateral interbody fusion patients, an anterior lumbar plexus position on preoperative supine MRI independently predicted postoperative motor deficits (OR 14.4), supporting MRI-based risk assessment and counseling.
In a retrospective database study of diabetic patients having posterior cervical surgery, preoperative GLP-1 agonist use was linked to fewer complications and revisions, with outcomes similar to prior bariatric surgery patients; residual confounding remains possible.
In 171 children operated on for Chiari I or tethered cord, scoliosis progressed in 37% of those with preoperative scoliosis, de novo scoliosis was uncommon (4%), and brace-compliant patients progressed less, so ongoing surveillance is warranted.
In matched lumbar stenosis patients, spinal epidural lipomatosis was linked to higher ApoB and a more atherogenic lipid profile, plus worse disability and leg pain, suggesting systemic lipid dysfunction rather than purely local fat deposition.
In 27 patients, DCE-MRI showed spinal osteosarcoma metastases are hypervascular, and plasma volume fell about 46% after radiation, suggesting perfusion imaging could noninvasively track treatment response.
In 101 surgical patients with metastatic spinal cord compression, unsupervised clustering identified four preoperative phenotypes; chronic, severe deficit with sensory loss predicted the poorest motor recovery, which may help guide counseling.
In 668 early-onset scoliosis patients, standard-standard versus standard-offset magnetically controlled growing rod orientation showed similar lengthening and complication rates at 2 and 5 years, so orientation choice shouldn't change expectations.
In 72 patients, postembolization CT-DSA only moderately agreed with catheter angiography, and residual tumor enhancement was not significantly associated with surgical blood loss, so its predictive value needs further validation.
Avoidance of vascular injury during trans-psoas approaches; awareness of venous anatomy on MRI.
In 144 trans-psoas lateral surgery patients, the iliolumbar and variant veins were visible on routine preoperative MRI; veins proximal to L4-5 larger than the exiting nerve root pose a hemorrhage risk, so review MRI when planning.
Narrative review adapting the NOMS framework to cervical spine tumors, emphasizing junctional instability, systemic fitness, and multidisciplinary planning, with surgery mainly for decompression, stabilization, and diagnosis alongside radiation and systemic therapy.
In 13 comparative studies (1,432 patients), OLIF had shorter hospital stay and greater sagittal vertical axis correction than supine ALIF, with similar complications and patient-reported outcomes, including in fusions to the sacrum.
MR spectroscopy in the diagnosis of lumbar discogenic pain.
In 20 patients with axial low back pain, MR spectroscopy agreed with low-pressure provocative discography in 70-87% of 55 discs, suggesting it may become a noninvasive alternative.
In 299 ACDF patients, more fused levels, older age, and higher preoperative Neck Disability Index independently predicted greater postoperative care intensity, while expectations and depression scores did not, which may help select outpatient candidates.
Meta-analysis of 23 studies found about 17% instrumentation failure after total en bloc spondylectomy, rising with longer follow-up, plus 44% complications and 2.7% mortality, supporting at least five years of radiographic surveillance.
In 192 Lenke 1 AIS patients, achieving calculated ideal thoracic kyphosis after PSF did not affect SRS-22 outcomes at 5 years, questioning current definitions of ideal sagittal alignment.
In 357 adults fused from the lower thoracic spine to the pelvis, residual positive T4-L1PA mismatch was associated with proximal junctional kyphosis and revision but not rod fracture, and was driven by hyperlordotic lordosis distribution.
Introduces GSDI-5, a composite sagittal alignment score including the upper cervical spine; in 201 adults it distinguished forward head posture slightly better than TPA, suggesting an exploratory complementary measure.
In 162 patients, canal bone ratio measured 7 cm below the lesser trochanter on standard radiographs, combined with age, sex, and BMI, showed moderate discrimination (AUC 0.78) for DXA-defined osteoporosis but needs external validation.
In 102 patients, L5-S1 ALIF with posterior fusion restored L4-S1 and L5-S1 lordosis equivalently to the preoperative plan (within ±2.5°), regardless of the L4-5 fusion technique.
In 10 patients with persistent ventral spinal CSF leaks after a failed open intradural or endoscopic repair, switching to the other approach resolved the extradural collection in 8 of 10 without complications.
After vertebral augmentation for osteoporotic compression fractures, patients 80 and older re-fractured much sooner (about 11 vs 26 months) and had different risk factors, supporting age-stratified prevention strategies.
Using four cases and a narrative review, this paper outlines surgical decision-making for en bloc resection of primary malignant subaxial cervical spine tumors, emphasizing planning, multistage approaches, and alternatives when en bloc resection is not feasible.
Narrative review offers a structured framework for reading acute postoperative MRI after lumbar fusion, separating benign expected changes and metal artifact from pathologic findings (dural sac compression, rim-enhancing collections) to avoid unnecessary reoperation.
State-of-the-art review in AI and digital technologies for spine deformity.
This state-of-the-art review surveys AI and digital tools across spinal deformity care, concluding most are decision-support tools with promising performance but limited multicenter, prospective validation.
This scoping review of 26 studies finds spine digital twins and multimodal AI remain largely conceptual, with modest static prediction models and no prospective validation showing better decisions, so they are not ready for clinical use.
Contemporary Management of Standard Chordoma Arising in the Mobile Spine and Sacrum.
Chordoma management centers on en bloc resection with negative margins, yet late recurrence reaches up to 50%; advanced radiation (SBRT, proton, carbon ion) increasingly serves as adjuvant or standalone therapy within a multidisciplinary approach.
Hip Spine Syndrome: Management of Patients With Concurrent Hip and Spine Degenerative Pathologies.
Review of hip-spine syndrome, advising multidisciplinary care, identifying the primary pain generator through examination and injections, and weighing clinical, radiographic, and surgical factors when deciding whether to treat the hip or spine first.
A 50-participant international consensus process ranked five prehabilitation themes for spine surgery, with education and psychological preparation prioritized, to guide design of programs aimed at improving postoperative recovery.
Review: sacroiliac joint dysfunction causes roughly 10-38% of low back pain; examine it routinely with multiple provocation tests, escalate treatment from least to most invasive, and note that lumbar fusion accelerates SIJ and hip degeneration.
The use of diffusion tensor imaging in spinal pathology: a comprehensive literature review.
Systematic review finds spinal diffusion tensor imaging, mostly studied in cervical myelopathy, may aid surgical decisions and prognosis across spinal pathologies, though larger prospective studies with longer follow-up are still needed.
Literature review of bone loss after cervical disc arthroplasty finds little quality evidence on management, so authors recommend close radiographic and CT follow-up, with intervention guided by progression and symptoms.
Narrative review argues adolescent idiopathic scoliosis arises from vertebrae and discs growing faster than ligaments, with reduced spinal compression and low muscle mass favoring a mechanical, vicious-circle deformity; may aid earlier diagnosis and prevention.
