A lesion of the lumbar posterior endplate is sometimes identified in the spinal canal of children and adolescents; it causes symptoms similar to those of a herniated disc. However, the pathology of the endplate lesion and the pathology of the herniated disc are different. We present a rare case of a 23-year-old woman who developed progressive palsy of the lower leg caused by huge lumbar posteri...

Lumbar disc herniation is one of the most common medical and surgical problems all over the world. The vast majority of lumbosacral radiculopathies are caused by paracentral herniation. However, Hood reported that far lateral lumbar disc herniation (FLLDH) accounts for 2.8 – 10% of all disc herniations. Over 75% of FLLDHs occur at the L3 –L4 and L4 – L5 levels. In addition, FLLDH presents a cli...

BACKGROUND The intervertebral disc has been implicated as an etiology of chronic lumbar spine pain based on clinical, basic science, and epidemiological research. However, there is lack of consensus regarding the diagnosis and treatment of intervertebral disc disorders. Based on controlled evaluations, the lumbar intervertebral discs have been shown to be sources of chronic back pain without di...

The authors report 2 cases of nerve root herniation after discectomy of a large lumbar disc herniation caused by an unrecognized dural tear. Patients complained of the abrupt onset of radiating pain after lumbar discectomy. Magnetic resonance imaging showed cerebrospinal fluid signal in the disc space and nerve root displacement into the disc space. Symptoms improved after the herniated nerve r...

Biomechanical analyses on lumbar spine under compressive load and flexion torque were performed using a nonlinear three-dimensional finite element method to evaluate the stability of artificial disc replacement. We prepared a validated intact lumbar L4-L5 motion segment and artificial disc inserted motion segment by replacing intact disc with the artificial disc which is being developed. Effect...

STUDY DESIGN Retrospective study. PURPOSE The objective of the study is to evaluate the relationship between the detection rate of lumbar disc herniation and socioeconomic status. OVERVIEW OF LITERATURE Income is one important determinant of public health. Yet, there are no reports about the relationship between socioeconomic status and the detective rate of disc herniation. METHODS In th...
