While microstructural observations have improved our understanding of possible pathways of herniation progression, no studies have measured the mechanical failure properties of the inter-lamellar matrix (ILM), nor of the adjacent lamellae during progression to herniation. The aim of this study was to employ multiscale, biomechanical and microstructural techniques to evaluate the effects of progressive induced herniation on the ILM and lamellae in control, pre-herniated and herniated discs (N = 7), using 2 year-old ovine spines...

BACKGROUND: Lumbar herniated disc is a "preference-sensitive" condition, in which the optimal treatment choice is crucially dependent on an informed patient's goals and values. Little is known about decisional conflict, defined as an individual's level of uncertainty regarding a decision, in patients considering treatment for lumbar herniated discs. Our work aims to identify factors associated with decisional conflict and areas for improved shared decision-making. METHODS: We prospectively surveyed patients seeking treatment for a lumbar herniated disc at L4-L5 and/or L5-S1 with a physician at the UCLA Spine Center...

BACKGROUND: Lumbar disc herniation (LDH) is a common degenerative disease of the lumbar spine with a prevalence of 1-3% in population studies according to some authors. In 10% of patients there is a fragment migrated cranially in the Macnab's "hidden zone". In selected cases, this fragment can be removed with a translaminar approach that has been described in 1998. Aim of our work is to provide a detailed description of the technical advantages and pitfalls of such approach reviewing a consecutive series of patients...

As a self-protective mechanism of cells, autophagy of cells can maintain cell stability by degrading self-aging substances, and it can be highly induced. The ability of autophagy to degraded cells will decrease with age. The resorption phenomenon after lumbar disc herniation is one of the effective mechanisms in conservative treatment of lumbar disc herniation. The degenerative lesion of intervertebral disc is one of the main reasons of lumbar disc herniation. Cell autophagy is extensive participation in the degeneration of lumbar intervertebral disc, delaying the occurrence of degenerative disease...
