to assess clinical [[predictor]]s of symptom improvement following reinforced radiculoplasty in patients with symptomatic sacral [[Tarlov cyst]]s (TCs).
Reinforced radiculoplasty significantly improves [[pain]] and [[numbness]] in sacral TC patients. Greater likelihood of pain-free status is associated with older age and lower preoperative [[VAS]] scores. No variables significantly predicted [[numbness]] relief

**Critical Review:**  

The study targets an underexplored treatment avenue—reinforced radiculoplasty—for symptomatic Tarlov cysts, an entity often managed conservatively due to unclear pathophysiology and outcome data. The authors utilize a small retrospective sample, limiting statistical power and generalizability. While binary logistic regression is appropriately applied, the absence of a control group and the reliance on telephone follow-ups raise concerns regarding recall bias and subjective assessment of outcomes. Furthermore, the study fails to delineate surgical technique variability or operator-dependence, critical factors in neurosurgical outcome studies. The lack of correlation with imaging changes and omission of bowel/bladder symptom stratification are notable limitations.

**Final Verdict:**  

Preliminary evidence, not [[practice-changing]]; [[hypothesis-generating]] at best. Methodological shortcomings and small sample size warrant skepticism.

**Takeaway for the Practicing Neurosurgeon:**  

Reinforced radiculoplasty may offer pain relief in older patients with lower baseline VAS, but clinical decision-making should remain cautious pending stronger prospective or comparative data.

**Bottom Line:**  

Promising but inconclusive data—underscores the need for controlled trials in Tarlov cyst management.
