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

+ | from Neurosurgery, | ||
+ | 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), | ||

+ | ===== Critical evaluation ===== | ||
+ | |||
+ | * **Population & design** | ||
+ | * Large cohort (n=203), though exclusively patients undergoing vertebroplasty (selection bias). Retrospective design limits control of confounders; | ||
+ | * IRB‐approved, | ||
+ | |||
+ | * **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, | ||
+ | |||
+ | * **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, | ||
+ | * 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/ | ||
+ | * 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. | ||
