Classification of Schmorl's nodes of the lumbar spine and association with disc degeneration: a large-scale population-based MRI study

摘要

Objective: Schmorl's nodes (SN) are highly associated with lumbar disc degeneration (DD). However, SN present with different morphologies/topographies that may be associated with varying degrees of DD. This study proposed a classification of SN to determine their morphological/topographical prevalence and association with the severity of DD.
