The thoracolumbar junction is the of thoracic and lumbar spine subjected to high biomechanical stress. With rapid development society, morbidity increases every year. Thoracolumbar fracture may affect stability even result in paralysis via compression spinal cord. As a advancements modern medicine, theoretical practical aspects concerning have made great progress. However, due complexity fractu...

We have studied fracture-dislocation of the fifth lumbar vertebra in seven patients and reviewed 50 previously reported cases. Based on this information, we have classified the injury into five types: type 1, unilateral lumbosacral facet-dislocation with or without facet fracture; type 2, bilateral lumbosacral facet-dislocation with or without facet fracture; type 3, unilateral lumbosacral face...

Stress fractures of the upper extremity and thorax are often unrecognized injuries in athletes and nonathletes. The authors reviewed the causative activities and anatomic distribution of rib and upper-extremity stress fractures. Radiographic and clinical information was reviewed for each case to determine anatomic site and causative activity of each stress fracture. Stress fracture, although an...

A detailed lumbar spine FE component model (including vertebrae, inter-vertebral discs, all ligaments and facet joints of T12-L5) was built per the Global Human Body Model Consortium (GHBMC) CAD data. The lumbar model was correlated with the Post-Mortem Human Subject (PMHS) lumbar spine tests under flexion, compression and anterior shear loading modes in the physiological ranges (Belwadi, 2008)...
