7 Αυγ 2023 · Spondylolysis is a unilateral or bilateral defect in the region of the pars interarticularis, which may or may not be accompanied by the vertebral body slippage. It is most commonly the sequelae of repetitive trauma to the growing immature skeletal architecture among a genetically susceptible individuals.
7 Αυγ 2023 · Identify the different types of spondylolisthesis, differentiating the patholological features that distinguish each variety. Outline the components of a proper evaluation and assessment of a patient presenting with lumbar spondylolysis/spondylolisthesis, including any indicated imaging studies.
17 Ιουλ 2024 · Spondylolysis, commonly known as pars interarticularis defect or pars defect, is a defect in the pars interarticularis, the portion of the vertebral neural arch that connects the superior and inferior articular facets. It usually occurs in the lumbar spine. Epidemiology.
24 Δεκ 2023 · Pediatric Spondylolysis & Spondylolisthesis represent a continuum of disease where there is a fracture of the pars interarticularis (spondylolysis) which may progress to anterior subluxation of one vertebral body anterior to the adjacent inferior vertebral body (spondylolisthesis).
Lumbar pars interarticularis (PI) injury or spondylolysis occurs only in humans. This represents a stress fracture of the PI. Excessive loading in repetitive hyperextension is a significant risk factor and occurs most commonly at L5 followed by L4.
The aim of this review was to provide of the current knowledge in pathophysiology, diagnosis and management of spondylolysis based on the authors' experience and the pertinent medical literature. Spondylolysis represents a weakness or stress fracture in one of the bony bridges that connect the upper with the lower facet joints of the vertebra.
Spondylolysis refers to a weakening or other defect in a specific region of the vertebra called the pars interarticularis. These defects may be caused by repetitive stress. Spondylolisthesis refers to anterior slippage (displacement) of the vertebrae. This is often the result of bilateral spondylolysis, a so-called isthmic spondylolisthesis.
