EFFECT OF GRADED POSTERIOR ELEMENT AND LIGAMENT REMOVAL ON ANNULUS STRESS AND SEGMENTAL STABILITY IN LUMBAR SPINE STENOSIS: A FINITE ELEMENT ANALYSIS STUDY

The study aimed to investigate the impact of posterior element and ligament removal on the maximum von Mises stress, and maximum shear stress of the eight-layer annulus for treating stenosis at the L3-L4 and L4-L5 levels in the lumbar spine.Previous studies have indicated that laminectomy alone can result in segmental instability unless fusion is p

Abstract Authors of a matched cohort study claimed the NHS Health Check programme reduced total mortality 23% and liver cirrhosis incidence 44%.Such impressive results require critical scrutiny, especially as the intervention targets a large, predominantly healthy population, and as it has harms and costs.Eleven high-quality randomised trials conta

Viperid venoms often contain mixtures of Asp49 and Lys49 PLA2 myotoxin isoforms, relevant to development of myonecrosis.Given their difference in Media catalytic activity, mechanistic studies on each type require highly purified samples.Studies on Asp49 PLA2s have shown that enzyme inactivation using p-bromophenacyl bromide (p-BPB) drastically affe
