spondylolysis/asthenia

BACKGROUND Spondylolysis is a common occurrence for adolescent athletes who have low back pain. The injury involves a defect in the pars interarticularis, occurring as a result of repeated hyperextension and rotation. METHODS Clinical findings might include tightness of the hip flexors and

OBJECTIVE To discuss the presence of spondylolysis at L2 in identical twins. METHODS Twin 61-year-old brothers reported insidious low back pain (LBP) of relatively recent onset. Both engaged in running as their main form of exercise. One had spondylolisthesis and history of significant traumatic

OBJECTIVE This study characterized the defect using neuroimmunologic and inflammatory cell analysis. BACKGROUND Spondylolysis/spondylolisthesis is thought to be caused by a congenital weakness and mechanical stress causing a fracture associated with defective healing. Most of the spondylolysis

Several reports have described the coexistence of spina bifida occulta (SBO) and spondylolysis, but the majority of defects occur at L5. No report has described the coexistence of SBO and spondylolysis at the thoracolumbar junction. We report a case of SBO with spondylolysis at L1, presenting cauda

A case is reported in which there was bilateral spondylolysis involving LV3, LV4 and LV5. It is thought that the condition is due to postural stress in a patient having a predisposing genetic weakness of the pars interarticularis.

Spondylolysis is a fracture of the pars interarticularis, the portion of the neural arch that lies between the superior articular facets and the inferior articular facets. Clinical evidence has suggested repetitive trauma to be the most probable cause, even though morphological weakness of the

METHODS Epidemiological analysis using CTs. OBJECTIVE To investigate the true incidence of lumbar spondylolysis in the general population in Japan. BACKGROUND Although there have been several reports on the incidence of lumbar spondylolysis, they had some weakness. One of them concerns the subjects

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

METHODS This study analyzed the skeletal-age-dependent strength of the lumbar growth plate to resist anterior shearing forces using the MTS system in the immature calf spine with pars defects. OBJECTIVE To clarify the pathomechanism of the skeletal-age-dependent incidence of slippage in pediatric

Over the past seven years, 96 PLIF operations were performed with the autologous bone graft method. In 44 cases, unicortical bone grafts were obtained from the posterior iliac crest area. In the remaining 52 cases, bicortical bone grafts were obtained from the anterior iliac crest. The failure rate

BACKGROUND In children with cerebral palsy, primary (eg, abnormal muscle tone and weakness) and secondary impairments (eg, contractures) can modify pelvic-spinal alignment. The main aim of this article was to establish a new approach to pelvic-spinal analysis in children with cerebral palsy, taking

Degenerative spondylolisthesis with or without spondylolysis, multiply recurrent disk herniation, and degenerative disk disease commonly presents as back and leg pain, weakness and paresthesias. Surgical intervention, to include lumbar decompression with instrumented fusion with or without interbody
