Highlights

Spinal Trauma & Fracture Care

This month's trauma literature spans epidemiology, surgical technique, and functional recovery. A 10-year cohort characterizes the epidemiology, AO morphology, and diagnostic delays of discontinuous thoracolumbar fractures [13], while GBD-based analysis quantifies the disease burden of road-injury-related spinal fractures among working-age adults in China [14], and a rural tourist-area series informs seasonal resource allocation [15]. For operative management, a two-year radiographic comparison of percutaneous versus open pedicle screw fixation for thoracolumbar burst fractures informs technique selection [12], and occupational outcomes after work-related AO type A1 compression fractures link treatment strategy to sick-leave duration [16]. A related review addresses vertebral compression and pelvic insufficiency fragility fractures, emphasizing diagnosis, nonoperative care, and secondary fracture prevention [3].

Adolescent Idiopathic Scoliosis

Two studies refine risk stratification and implant surveillance in AIS. A large prospective analysis of 5,206 instrumented fusions with multimodal neuromonitoring identifies curve-specific alert risk, highest in Lenke type 4 and lowest in type 5 curves, along with triggering events and outcomes after IONM alerts [1]. Complementing this, serial serum titanium, cobalt, and chromium measurements at one and six months after posterior instrumented fusion were modeled against revision-related procedures after a six-month landmark, developing a prognostic model for later revision surgery based on early metal ion profiles [5].

Spine Oncology & Reconstruction

Oncologic reconstruction and management frameworks feature prominently. A prospective controlled cohort comparing 3D-printed patient-specific PEEK implants versus titanium mesh cages after spondylectomy for spinal tumours found markedly lower subsidence with PEEK at 12 months, with secondary endpoints covering osseous integration, segmental height, quality of life, and complications [6]. A comprehensive review of spinal tumour surgery outlines decision-making frameworks (NOMS, SINS, Tokuhashi), the role of en bloc resection for primary malignancies, separation surgery plus stereotactic radiosurgery for metastatic disease, and emerging minimally invasive, robotic, and ablative technologies [11].

Spinopelvic-Hip-Knee Interactions

Several studies examine how spinal alignment and pathology influence lower-extremity arthroplasty outcomes. Coronal spinal imbalance dictated side preference in symmetrically well-aligned bilateral total knee arthroplasty, measured via C7 plumb line to central sacral vertical line distance [10]. Patients requiring both lumbar fusion and total hip arthroplasty showed delayed time to clinically relevant improvement (MCID) on PROMIS and HOOS measures, with surgical sequence effects analyzed [9]. Low back pain and depression each independently worsened patient-reported outcomes after primary TKA, with additive effects when co-occurring [19]. A commentary discusses archetypal lumbopelvic profile analysis for predicting adverse spinopelvic mobility after THA [20], and scapular orientation was associated with spinopelvic parameters including lumbar lordosis and pelvic incidence [8].

Degenerative Lumbar Care & Education

Degenerative spine management and patient-centered care round out the digest. In patients aged 75 and older undergoing lumbar spinal stenosis surgery, frailty (mFI-5) and cognitive impairment predicted early medical complications beyond age and comorbidity scores, supporting geriatric assessment before surgery [18]. A randomised multicenter study found video-based education improved patient understanding of lumbar decompression surgery compared with a written leaflet, with comprehension assessed at days 1, 15, and 30 [21]. Quantitative MRI demonstrated level-dependent changes in cervical multifidus fatty infiltration and functional cross-sectional area after ACDF, bridging muscle composition and clinical outcomes [4].

Global Spine Access & Systems

Health-systems and access themes complete the digest. A practical review of spine surgery missions in low-resource settings, based on collaborative experience in Jamaican hospitals, addresses financial planning, equipment logistics, ethical patient selection, and sustained partnerships with host institutions [2].

This review addresses vertebral compression and pelvic insufficiency fractures, which are common in osteoporotic patients, often underdiagnosed, and associated with increased morbidity and mortality. Most patients can be managed nonoperatively with pain control, mobility optimization, nutrition, and secondary fracture prevention, while surgery is reserved for intractable pain, functional decline, progressive deformity, or neurologic deficits, highlighting an important unmet care need.

12. Wung C, Chang C, Hsu C, et al. Longitudinal Radiographic Comparison of Percutaneous and Open Pedicle Screw Fixation for Thoracolumbar Burst Fractures: A Two-Year Follow-Up Study. Injury 2026. doi:10.1016/j.injury.2026.113699

This two-year longitudinal radiographic study compared percutaneous versus open pedicle screw fixation for thoracolumbar burst fractures, tracking Cobb angle and alignment changes over follow-up. The abstract indicates the comparison focused on radiographic maintenance of correction between the two techniques. Findings inform surgeon selection between percutaneous and open fixation based on expected radiographic outcomes at two years.

13. Zeng Y, Tu C, Zhu L, et al. Epidemiology, AO morphology, and diagnostic delay of discontinuous thoracolumbar fractures: a 10-year single-center cohort study. Injury 2026. doi:10.1016/j.injury.2026.113702

This 10-year single-center cohort characterized the epidemiology, AO morphological classification, and diagnostic delays of discontinuous (non-contiguous) thoracolumbar fractures. The study quantifies injury patterns and highlights delays in recognizing these fractures. Greater awareness of discontinuous fracture patterns may reduce missed diagnoses in trauma patients with thoracolumbar injuries.

14. He J, Liu S, Li M, et al. Disease Burden of Spinal Fractures Attributable to Road Injuries Among Working-age Population in China During 1990-2023: An Analysis Based on the Global Burden of Disease 2023. Injury 2026. doi:10.1016/j.injury.2026.113704

Using Global Burden of Disease 2023 data, this study analyzed disease burden of spinal fractures attributable to road injuries among China's working-age population from 1990 to 2023. It quantifies temporal trends in incidence, mortality, and disability from road injury-related spinal fractures. These findings support targeted road safety and trauma system resource allocation for this economically active population.

15. Peppucci E, Ferlito D, Meletti L, et al. Traumatic spinal injuries in a rural tourist area: epidemiology, seasonal trends and implications for healthcare resource allocation. Injury 2026. doi:10.1016/j.injury.2026.113710

This epidemiological study examined traumatic spinal injuries in a rural tourist area, analyzing seasonal trends and their implications for healthcare resource allocation. It identified temporal patterns in spinal trauma incidence linked to tourism-related activity. Results can guide staffing and trauma capacity planning in rural regions with seasonal visitor surges.

This study assessed occupational recovery after work-related AO Spine type A1 compression fractures, examining the association between treatment strategy and sick-leave duration. It compared return-to-work outcomes across different treatment approaches for these low-grade compression fractures. Results help guide treatment selection with consideration of occupational recovery and socioeconomic impact in working patients.

Adolescent Idiopathic Scoliosis (2)

1. CreveCoeur TS, Samdani AF, Schüpper AJ, et al. Diagnostic Performance and Clinical Outcomes of Intraoperative Neuromonitoring in Adolescent Idiopathic Scoliosis. Journal of Bone and Joint Surgery 2026. doi:10.2106/jbjs.25.01577

In a prospective cohort of 5,206 AIS fusion patients with multimodal IONM, alerts occurred in 5% and were most common in Lenke type 4 curves (8%) and least common in type 5 (2%), with larger preoperative major Cobb angles and Ponte osteotomy use also associated with alerts. These curve-specific risk factors can guide preoperative counseling and heightened intraoperative vigilance in higher-risk deformity corrections.

5. Li T, Alonge E, Ye F, et al. Early postoperative serum metal profiles and subsequent revision-related surgery after instrumented fusion for adolescent idiopathic scoliosis. International Orthopaedics 2026. doi:10.1007/s00264-026-07021-9

In 154 AIS patients undergoing posterior instrumented fusion, serum titanium, cobalt, and chromium measured at 1 and 6 months were modeled as predictors of revision-related surgery after a 6-month landmark using internally validated logistic models. The study addresses whether early postoperative metal ion profiles can prognosticate later revision procedures in instrumented scoliosis fusion.

Spine Oncology & Reconstruction (2)

6. Zaborovskii N, Masevnin S, Ptashnikov D, et al. Three dimensional printed patient-specific PEEK versus titanium mesh cage for anterior column reconstruction after spondylectomy for spinal tumours: a prospective controlled cohort study. International Orthopaedics 2026. doi:10.1007/s00264-026-07019-3

In a prospective controlled cohort of adults undergoing vertebral body replacement after spondylectomy for spinal tumours, 3D-printed patient-specific PEEK implants showed markedly less subsidence at 12 months than titanium mesh cages (3.7% vs 42.3%) with better endplate conformity. These findings support patient-specific PEEK implants as a favourable option for anterior column reconstruction in spinal tumour surgery.

11. Angelini A, Ruggieri P. Surgery of the tumors of the spine. EFORT Open Reviews 2026. doi:10.1530/eor-2026-0089

This narrative review synthesizes current management of primary and metastatic spinal tumours, covering decision-making frameworks (NOMS, SINS, Tokuhashi), indications for en bloc resection, and the role of separation surgery with stereotactic radiosurgery in metastatic disease. It highlights minimally invasive techniques as a patient-tailored complement to open surgery and anticipates advances in robotics, ablation, and biomaterials. Clinicians can use these structured frameworks to individualize oncologic spine surgery based on tumour biology, prognosis, and mechanical stability.

Spinopelvic-Hip-Knee Interactions (5)

8. El Abiad R, Maalouf Y, Daher M, et al. The association between scapular orientation and spinopelvic parameters. Journal of Shoulder and Elbow Arthroplasty 2026. doi:10.1016/j.jsea.2026.100032

In a retrospective analysis of adults without spinal deformity or upper extremity pathology undergoing PET imaging, scapular orientation measures (internal rotation, protraction, upward rotation) were correlated with full spinopelvic parameters including lumbar lordosis, pelvic incidence, pelvic tilt, and sacral slope. The findings extend prior work beyond thoracic kyphosis and may inform integration of spinopelvic alignment into reverse total shoulder arthroplasty planning.

9. Sauder N, Williams DL, Singh R, et al. Patients Requiring both Lumbar Spinal Fusion and Total Hip Arthroplasty Have Delayed Clinically Relevant Global Improvement Timelines. Findings from a Propensity Score-Matched Analysis of Time to MCID. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.08.049

Using a propensity score-matched registry analysis (183 dual-procedure patients vs 732 THA-only controls), the authors compared time to minimal clinically important difference (MCID) in PROMIS PF-10a, PROMIS Global Physical, and HOOS-PS after THA, including subgroup analysis by surgical sequence. Patients undergoing both lumbar spinal fusion and THA achieved MCID significantly later (e.g., PROMIS Global Physical 5.91 vs 5.15 months), with sequencing also influencing recovery timelines. Surgeons should counsel combined LSF/THA patients that clinically relevant functional improvement takes longer than standard THA recovery expectations.

10. Siripullop T, Ngarmukos S, Jaruthien N, et al. Coronal Spinal Imbalance Dictated Side Preference in Symmetrically Well-Aligned Bilateral Total Knee Arthroplasty. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.08.054

In 122 patients with symmetrically well-aligned bilateral TKA evaluated on full-body radiographs at mean 35-month follow-up, the authors measured coronal spinal imbalance via C7 plumb line to central sacral vertical line distance and assessed clinical outcomes and side preference. Patients with balanced spines mostly had no side preference (71%), whereas 91.5% of those with coronal spinal imbalance preferred the same knee side. Coronal spinal balance appears to influence patient-perceived knee outcomes after TKA, suggesting spinal alignment should be considered when evaluating asymmetric results in well-aligned arthroplasties.

19. Haji Boloori F, Kubiak A, Rezazadeh Shirazi A, et al. Low Back Pain and Depression Are Associated with Worse Patient-Reported Outcomes After Primary Total Knee Arthroplasty. The Journal of Arthroplasty 2026. doi:10.1016/j.arth.2026.09.024

A registry-based study of 4,173 primary total knee arthroplasty patients compared outcomes across groups with low back pain, depression, both, or neither. Patients with either condition had lower adjusted Oxford Knee Score improvement, and co-occurrence of both was associated with the worst outcomes, including reduced odds of achieving the minimal clinically important difference. Clinically, screening for both conditions preoperatively may identify patients at risk for suboptimal improvement and guide expectations or targeted interventions.

20. Solla F, Roussouly P. Comments on: “An archetypal analysis of lumbopelvic profiles could help predict adverse spinopelvic mobility after total hip arthroplasty” by Aubert T, Hallé A, Aubert O, published in Orthop Traumatol Surg Res. 2026: 104662. doi: 10.1016/j.otsr.2026.104662. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104903

This is a letter to the editor by Solla and Roussouly commenting on Aubert et al.'s archetypal analysis of lumbopelvic profiles for predicting adverse spinopelvic mobility after total hip arthroplasty. As a correspondence piece, it offers scholarly critique or methodological commentary rather than new data. Its clinical relevance lies in refining interpretation of spinopelvic mobility assessment in arthroplasty planning.

Degenerative Lumbar Care & Education (3)

4. Folkerts T, Tripathi R, Caffard T, et al. Level-dependent changes in cervical multifidus composition following anterior cervical discectomy and fusion: bridging quantitative MRI and clinical perspectives. Archives of Orthopaedic and Trauma Surgery 2026. doi:10.1007/s00402-026-06495-x

This longitudinal quantitative MRI study evaluated fatty infiltration and functional cross-sectional area of the cervical multifidus and rotatores before and after ACDF, assessing whether changes differ by surgical level. It provides scarce longitudinal data on post-ACDF paraspinal muscle composition changes, with potential implications for understanding neck outcomes after anterior cervical surgery.

18. Lemonnier N, Piccot B, Lesage C, et al. Beyond age and comorbidities: frailty and cognitive impairment are associated with early medical complications after surgery for lumbar spinal stenosis in patients aged 75 years and older. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104882

A retrospective cohort of 143 patients aged 75 and older undergoing lumbar spinal stenosis surgery examined whether frailty (mFI-5) and geriatric parameters predict 30-day medical complications beyond age and comorbidity scores. Medical complications occurred in 38% and surgical complications in 30%, with frail patients showing higher medical complication rates. The clinical implication is that preoperative comprehensive geriatric assessment, including frailty and cognitive status, should complement age- and comorbidity-based risk stratification in the very elderly.

21. Redonnet J, Alixant P, Lamas V, et al. Patient understanding of lumbar spinal stenosis surgery: Video versus leaflet. Orthopaedics & Traumatology: Surgery & Research 2026. doi:10.1016/j.otsr.2026.104912

A prospective multicenter randomised study of 62 patients with symptomatic lumbar spinal stenosis compared a video-based educational tool against a written leaflet for preoperative understanding of lumbar decompression surgery. The video group achieved higher comprehension scores at day 15, a difference that persisted after multivariable adjustment. The clinical implication is that video-based education may enhance informed consent and should be considered alongside or instead of written materials.

Global Spine Access & Systems (1)

2. Nassar JE, Jenkins NW, Bailey S, et al. Spine Surgery Missions in Low-Resource Settings. Journal of Bone and Joint Surgery 2026. doi:10.2106/jbjs.26.00480

This review draws on spine surgery missions to two Jamaican hospital systems under the Back to Healing initiative to outline the financial, logistical, ethical, and relational elements of surgical outreach in low-resource settings. It emphasizes that sustainable impact depends as much on long-term partnership with host institutions and ethical patient selection as on equipment and operating-room logistics, and offers practical recommendations for planning missions.

7. Soliman E, Zeheiry M, Abu Halawa Y, et al. Impact of sex and HLA-B27 positivity on clinical characteristics and patient-reported outcomes in a cohort of Egyptian axial spondyloarthritis patients. BMC Musculoskeletal Disorders 2026. doi:10.1186/s12891-026-10296-z

This cross-sectional study of 256 Egyptian patients with axSpA found that women had higher disease activity, greater functional impairment, and poorer quality of life, while HLA-B27-positive patients more often had axial-dominant disease and HLA-B27-negative patients more peripheral manifestations, enthesitis, and dactylitis. The results underscore sex and HLA-B27 as determinants of axSpA phenotype and patient-reported outcomes in a Middle Eastern/North African cohort.

17. Datry V, Gagnepain E, Guillot M, et al. Medial clavicle resection for acute traumatic posterior sternoclavicular dislocation: Experience from Grenoble Alpes University Hospital. Injury 2026. doi:10.1016/j.injury.2026.113662

A retrospective case series from Grenoble Alpes University Hospital evaluated medial clavicle resection as treatment for acute traumatic posterior sternoclavicular dislocation. The findings support this approach as a viable option when stable reduction cannot be achieved or maintained. Clinically, the study informs surgical decision-making for this rare injury, suggesting resection may be considered in selected acute cases where reconstruction is impractical.
