Burst fractures most frequently affect the thoracolumbar spine due to the fulcrum of increased motion occurring at the T12-L1 junction. However, isolated burst fractures of the fifth lumbar (L5) vertebra can occur but are very rare. We present a woman with a fracture-dislocation of the fifth lumbar vertebra complicated by neurological damage. She was treated by posterior surgery with transpedic...

Eosinophilic granuloma (EG), a rare disorder of clonal proliferation of Langerhans cells, is a benign osseous variant of Langerhans cell histiocytosis. It involves patients of all ages, but most commonly affects children (18). It is mostly seen in the skull, long bones, pelvis and spine. When eosinophilic granuloma affects the spine, it is most often seen in the thoracic, and then lumbar and ce...

We studied 52 patients, each with a lumbosacral transitional vertebra. Using MRI we found that the lumbar discs immediately above the transitional vertebra were significantly more degenerative and those between the transitional vertebrae and the sacrum were significantly less degenerative compared with discs at other levels. We also performed an anatomical study using 70 cadavers. We found that...

OBJECTIVE To identify the correlations between the location of multifidus atrophy and the level of lumbar radiculopathy. METHODS Thirty-seven patients who had unilateral L4 or L5 radiculopathy were divided into 2 groups; the L4 radiculopathy (L4 RAD) group and the L5 radiculopathy (L5 RAD) group. Bilateral lumbar multifidus muscles at the mid-spinous process level of L4 vertebra (L4 MSP), the...

The vasospastic diseases and chronic pain related to lower limb have been successfully treated by surgical ablation of lumbar sympathetic trunk for last 80 years.Precise knowledge of anatomy of lumbar sympathetic trunk and its adjoining structures is mandatory for safe and uncomplicated lumbar and spinal surgeries.We aim to study the detailed anatomy of entry and exit of lumbar sympathetic trun...

Accurate Vertebra localization presents an essential step for automating the diagnosis of many spinal disorders. In case of MR images of lumbar spine, this task becomes more challenging due to vertebra complex shape and high variation of soft tissue. In this paper, we propose an efficient framework for spine curve extraction and vertebra localization in T1-weighted MR images. Our method is a fa...

Meningiomas in children account for less than 2% of all meningiomas, and their location in the spinal region is even less common. The authors present a case of a 20-month-old female who presented with lumbar back pain, neurogenic bladder and progressive paraparesis 6 months after she started to walk. Magnetic resonance imaging demonstrated an intradural extramedullary neoplasm extending from th...

The German Shepherd is among the breeds most prone to pathologies of lumbosacral spine. aim study was examine how presence spine pathology affects shape lumbar and dimensions individual vertebrae. Mathematical analysis consisted three measurements for each vertebra. Based on analysis, it concluded that there a correlation between height first five vertebrae occurrence transitional vertebra (LTV...

We report the case of a 66-year-old woman with tumor-induced osteomalacia (TIO) caused by fibroblast growth factor 23 (FGF-23) secreting mesenchymal tumor localized in a lumbar vertebra and review other cases localized to the axial skeleton. She presented with nontraumatic low back pain and spontaneous bilateral femur fractures. Laboratory testing was remarkable for low serum phosphorus, phosph...

The double S shape of the vertebral column is one of the most important evolutionary adaptations to human bipedal locomotion, providing an optimal compromise between stability and mobility. It is commonly believed that a six element long lumbar spine facilitated the critical adoption of lumbar lordosis in early hominins, which contrasts with five lumbars in modern humans and four in chimpanzees...
