 +===== Retrospective cohort analysis =====

 +In a retrospective cohort analysis  
 +Lee et al.  
 +from Neurosurgery, Ilsan Paik Hospital, Goyang, South Korea; Clinical Research Support Center, Inje University Ilsan Paik Hospital, Goyang, South Korea  
 +published in the [[Spine Journal]]  
 +to determine whether pedicle enhancement (PE) on contrast MRI predicts progressive collapse in acute osteoporotic compression fractures (OCFs), and to correlate enhancement degree with collapse risk  
 +PE, quantified by signal-to-noise ratio (SNR ≥ 89.3), along with age, BMI, and segmental kyphosis, significantly predicts progressive collapse (AUC 0.781). Collapse risk peaks within 1–2 months, stabilizing after three months

 +
 +===== Critical evaluation =====
 +
 +* **Population & design**  
 +  * Large cohort (n=203), though exclusively patients undergoing vertebroplasty (selection bias). Retrospective design limits control of confounders; level of evidence is III.  
 +  * IRB‐approved, but biopsy to confirm absence of malignancy was not routine—possible misclassification.  
 +
 +* **MRI assessment**  
 +  * SNR cutoff (89.3) yields sensitivity 71.1% and specificity 78.7%—moderate discrimination (AUC 0.781).  
 +  * Single‐center imaging, without axial MRI in most patients—may overlook key anatomical details.  
 +
 +* **Statistics & temporal trends**  
 +  * Survival (Kaplan–Meier) appropriately used to define timecourse. Notably, risk surges in first 1–2 months, plateau thereafter.  
 +  * Multivariable modelling less clear—details on variable selection, interaction, and potential overfitting lacking.  
 +
 +* **Clinical relevance**  
 +  * Identifies a measurable radiologic marker that could guide early intervention decisions.  
 +  * However, routine use of contrast MRI for all OCFs may be impractical, costly, and expose patients to Gd-based contrast risks.  
 +  * SNR threshold needs external validation; unclear whether adding PE changes management beyond standard risk factors.  
 +
 +* **Comparison with literature**  
 +  * Builds on prior recognition of pedicle enhancement/involvement in benign OCF; earlier studies warned against interpreting this only as malignancy :contentReference[oaicite:1]{index=1}.  
 +  * Advances by quantifying SNR rather than relying on qualitative assessment.  
 +
 +===== Final verdict =====  
 +Score: **6.0 / 10**  
 +The study offers a useful, quantifiable MRI biomarker and time course insight for OCF collapse risk. Yet limitations in patient selection, confirmatory pathology, and lack of external validation temper its immediate clinical adoption.
 +
 +===== Takeaway for the surgeon =====  
 +If contrast-enhanced MRI shows pedicle SNR ≥ 89.3, especially within 2 months of fracture, proactive management (bracing optimization or early vertebral augmentation) may be warranted. However, use within a broader risk stratification context and after further validation is essential.
 +
 +===== Bottom line =====  
 +Pedicle enhancement SNR is a moderate predictor of early progressive collapse in OCFs, but further prospective studies are needed before routine use.
