Ahérnia discal ocorre quando o núcleo pulposo e gelatinoso que constitui a parte central do disco intervertebral, prolapsa através da rotura do anel fibroso circundante e comprime as estruturas vizinhas. Quando uma hérnia discal comprime um nervo, pode causar dor, dormência e perda de força na área do corpo correspondente a
Ahipertrofia das articulações interapofisárias em L4-L5 e L5-S1 refere-se ao aumento anormal do tamanho das articulações entre as vértebras lombares L4 e L5, e entre L5 e S1. Essa condição é comumente associada à degeneração da coluna vertebral e ocorre principalmente devido ao
Inpatients with lower back and leg pain, lumbar foraminal stenosis (LFS) is one of the most important pathologies, especially for predominant radicular symptoms. LFS pathology can develop as a result of progressing spinal degeneration and is characterized by exacerbation with foraminal narrowing caused by lumbar

TheL5 S1 disc, in particular, is the most fragile and susceptible to protrusion since it often carries more weight than the other lumbar discs. (L5 is medical shorthand for the fifth vertebrae in the lumbar, or the lower part of the spine, and S1 denotes the first vertebrae in the sacrum. The L5 S1 disc is sandwiched between these two
BookshelfID: NBK448134 PMID: 28846354. Between each vertebral body of the spine are pads of fibrocartilage-based structures that provide support, flexibility, and minor load-sharing, known as the intervertebral discs. These are primarily composed of two layers: (1) a soft, pulpy nucleus pulposus on the inside of the disc and (2) a
BackgroundThe superior facet arthroplasty is important for intervertebral foramen microscopy. To our knowledge, there is no study about the postoperative biomechanics of adjacent L4/L5 segments after different methods of S1 superior facet arthroplasty. To evaluate the effect of S1 superior facet arthroplasty
However radiographic ASD at L5-S1 occurred in seven patients (12.1%), clinical ASD at L5-S1 occurred in three patients (5.2%), and one patient (1.7%) required surgery. In the group with pre-existing degeneration, L5-S1 degeneration was radiographically accelerated in four patients (18.2%) and
