Spondylolysis and spondylolisthesis in children and adolescents: I. Diagnosis, natural history, and nonsurgical management.
Spondylolysis and spondylolisthesis are often diagnosed in children presenting with low back pain. Spondylolysis refers to a defect of the vertebral pars interarticularis. Spondylolisthesis is the forward translation of one vertebral segment over the one beneath it. Isthmic spondylolysis, isthmic spondylolisthesis, and stress reactions involving the pars interarticularis are the most common for...
متن کاملRadiographic comparison between male and female patients with lumbar spondylolysis.
We studied the lumbar spines of 117 adults (39 women and 78 men) with spondylolysis unrelated to low back pain using multidetector computed tomography (CT). Of the 117 subjects with spondylolysis, including five with multiple-level spondylolysis, there were 124 vertebrae with spondylolysis. In adult lumbar spines with unilateral spondylolysis, there was no significant difference between the inc...
متن کاملAn experimental model of adult-onset slip progression in isthmic spondylolistesis.
Progressive spondylolisthesis may occur in adults with isthmic spondylolysis with an estimated incidence of 20%. This biomechanical study showed that in adult spines with bilateral L5 pars fractures, an anterior slip of L5 depends on the extent of the load-bearing deficiency of the disc and the presence of shear force across L5-S1. A combination of disc degeneration and muscle dysfunction may b...
متن کاملOsteological development of the vertebral column, paired, dorsal and anal fins in Rutilus caspicus, Pravdin (1927) (Teleostei: Cyprinidae)
Study of the osteological development in fishes is important from fisheries, biology and aquaculture points of views. It can be used as an early bio-indicator of non-optimal rearing conditions. The Caspian roach, Rutilus caspicus is a native cyprinid fish of the Caspian Sea that its artificial propagation has fulfilled in hatcheries to recruit its natural stocks. Hence, this study was conducted...
متن کاملVertebral body bone mineral density in patients with lumbar spondylolysis: a quantitative CT study.
PURPOSE Spondylolysis is known to be a part of a disease process, which describes a defect in the pars interarticularis of vertebra. We aimed to use quantitative computed tomography (QCT) to measure vertebral body bone mineral density (BMD) in patients with lumbar spondylolysis and compare it with readings in controls. METHODS Forty symptomatic patients with lumbar spondylolysis aged 18-52 ye...
