A Commentary on “International Practice Patterns in the Surgical Management of Primary Lumbar Disc Herniation: An AO Spine Cross-Sectional Study”

The surgical management of lumbar disc herniation (LDH) remains a cornerstone of spinal practice, yet it is characterized by significant global heterogeneity.In the article "International Practice Patterns in the Surgical Management of Primary Lumbar Disc Herniation: An AO Spine Cross-Sectional Study, " the authors present a robust dataset from 714 surgeons across five continents. 1 This study provides a valuable benchmark for the current "standard of care, " confirming that despite the marketing of novel technologies, the miniopen microscopic approach remains the dominant global gold standard (54.2%).Furthermore, the study establishes a reassuring ethical hierarchy in surgical decision-making, where neurological status is prioritized over subjective pain or patient demand.However, the reported utilization rates for endoscopic spine surgery (ESS)-specifically 8.4% for full-endoscopic and only 2.7% for unilateral biportal endoscopy (UBE)-warrant a nuanced interpretation, particularly regarding the Asia-Pacific (AP) region.While the AP region contributed nearly a quarter of respondents (24.8%), the data reveals a potential "East Asian Paradox" where the region known as the global epicenter of endoscopic innovation reported surprisingly low adoption rates. 2,3his discrepancy can be explained through a logical syllogism derived from the study's own multivariate analysis.First, the study's AP cohort was disproportionately composed of orthopedic surgeons (odds ratio [OR].2.85; p < 0.0001) compared to other regions. 1 Second, orthopedic surgeons in this survey were significantly more likely to prefer open approaches (OR, 2.46; p = 0.0025) and less likely to perform high-volume LDH surgeries than neurosurgeons. 1 Third, external literature confirms that the explosive growth of ESS, particularly UBE in South Korea and China, has been heavily driven by neurosurgical groups and specialized private spine centers. 4,5onsequently, it appears the survey may have inadvertently captured the "academic orthopedic" segment of the Asian market while missing the "high-volume endoscopic" segment.This suggests that the reported 2.7% global preference for UBE is likely a substantial Neurospine
