Why, After Lumbar Correction and Cervical Alignment, Does the Cervical Spine Drift Back Into Malalignment Two Years Later?
A retrospective cohort of 99 patients undergoing lumbar pedicle subtraction osteotomy (PSO) showed dramatic immediate improvements in cervical alignment, including reductions in cSVA, cervical lordosis, and T1 slope. The magnitude of these early changes was linked to higher pre‑operative sagittal vertical axis (SVA). Over a two‑year follow‑up, the cervical spine gradually drifted back toward malalignment, driven primarily by pelvic parameters such as pre‑operative pelvic tilt (PT) and PI‑LL mismatch. The study demonstrates that lumbar correction influences cervical posture in two distinct phases, each governed by different global alignment factors.
When the Data Favor Motion Preservation, How Long Does It Take for Surgeon Culture to Catch Up?
Recent IDE trial data on the Total Posterior Spine (TOPS) System suggest that motion‑preserving implants can match or exceed outcomes of traditional fusion for grade I degenerative spondylolisthesis at L4‑5. The study showed comparable pain relief, functional scores, and lower rates...
Pop Quiz: Do 10%, 25% or 50% of Your Patients Follow Your Post-Op Activity Instructions?
A single‑blinded randomized trial of 200 lumbar microdiscectomy patients compared traditional activity restrictions with an unrestricted, pain‑guided approach. Both groups wore activity monitors for a month, providing objective data on sitting, lifting, and movement. At one‑year follow‑up, there were no...
Why, if After 7 to 21 Years of Follow-Up Data, Disc Arthroplasty Has a Mere 0.67% Index Level Revision Rate,...
A large real‑world cohort of 1,187 lumbar total disc arthroplasty patients was followed for 7 to 21 years, revealing an index‑level revision rate of just 0.67% and an adjacent‑level surgery rate of 1.85%. Clinical outcomes—Oswestry Disability Index and VAS pain...
Should Depression Be on the Same Checklist as Smoking and Diabetes?
A propensity‑matched analysis of 11,570 elective single‑level lumbar fusion patients found that preoperative major depressive disorder (MDD) does not raise reoperation, mortality, or early emergency‑department visits. However, the same cohort showed markedly higher rates of new psychiatric diagnoses, somatic symptom...
Can Facet Arthroplasty Outperform TLIF for Spondy?
A prospective, multicenter FDA IDE trial compared the Total Posterior Spine (TOPS) facet arthroplasty system with traditional transforaminal lumbar interbody fusion (TLIF) in patients with single‑level grade I degenerative spondylolisthesis. At 24 months, TOPS achieved an 85% composite clinical success rate versus...
For Idiopathic Scoliosis Patients, Have You Considered Pre-Op Lung Training?
Anterior vertebral body tethering (AVBT) is gaining traction as a motion‑preserving alternative for adolescent idiopathic scoliosis, but postoperative pulmonary complications remain a concern. A retrospective review of 185 patients compared those who completed a three‑week preoperative pulmonary rehabilitation (PPR) program...
"Turn Research Into Results"
OTW Spine Research Hub, launched seven months ago, offers a dedicated platform that turns orthopedic and spine research PDFs into digestible, actionable content for surgeons. By leveraging its extensive reach within the orthopedic and spine community, the hub aims to...
CDR vs ACDF in the Back to Work Sweepstakes. Who Wins?
A new meta‑analysis of 16 randomized trials involving more than 5,600 patients compares anterior cervical discectomy and fusion (ACDF) with cervical disc replacement (CDR). The data show CDR patients return to work significantly faster – 33% more likely at six...
What’s the Actual Neurological Cost of a 3-Column Osteotomy?
A prospective multicenter study of 553 adult spinal deformity patients found that 130 (23.5%) underwent a three‑column osteotomy (3CO). Neurologic adverse events occurred in 23.1% of 3CO cases versus 15.4% without a 3CO, a statistically significant increase. Despite the higher...
When Is a High Readmission Patient Also a Happier Patient?
A retrospective cohort of 66 ankylosing spondylitis or DISH patients matched to 198 controls examined outcomes after elective cervical and lumbar fusion. After adjusting for comorbidities, the AS/DISH group was six times more likely to be readmitted within 30 days....
"Make Your Work Unmissable"
OTW, a digital platform targeting orthopedic and spine surgeons, promises to place research findings directly into clinicians' inboxes and social feeds. The service is positioned as a solution to the information overload that often buries valuable scientific work. Researchers are...
Is Cervical Radiculopathy Less of a Compression Problem and More of a Cellular Stress Cascade Triggered by Compression?
A recent animal study demonstrated that needle‑knife therapy alleviates cervical spondylotic radiculopathy in rats by dampening endoplasmic reticulum stress through the IRE1α‑XBP1 arm of the unfolded protein response. The treatment improved pain thresholds, normalized gait, reduced microglial activation, and lowered...
Really Need Long Pedicle Screws in Good Bone? Ever?
A cadaveric biomechanical study compared 35 mm “short” pedicle screws with the longest possible screws in lumbar vertebrae under cyclic fatigue loading. In vertebrae with normal bone density, both screw lengths endured similar fatigue loads (~315 N), indicating the pedicle alone provides...
Can Facet Arthroplasty Outperform TLIF for Spondy?
A prospective, multicenter FDA IDE trial compared the Total Posterior Spine (TOPS) facet arthroplasty system with traditional transforaminal lumbar interbody fusion (TLIF) in 249 patients with single‑level grade I degenerative spondylolisthesis. At 24 months, TOPS achieved an 85% composite clinical success rate...
