Local tenderness at the affected level can be detected during passive forcing of extension in the prone-lying position.129 Because the first and second lumbar vertebrae are the levels in the axial skeleton most commonly affected,130 the discovery of pain at the ‘forbidden area’ during selective...
of thelumbar vertebrae. It projects inferiorly, and its posterior aspect is more rounded in appearance than the rest of the lumbarspinous processes(seeFig. 7-16). The TPs of L5 are much wider from anterior to posterior and from superior to inferior than those of the rest of thelumbar ...
The lumbar vertebrae, except for the fifth, probably show fewer variations of a congenital nature than any other vertebra. Congenital block vertebra, or congenital synostosis, occurs as a result of a disturbance in segmentation of the somites during development of the vertebral column. The chapter...
Results BMD of trabecular and cortical regions of interest (ROI) of the third, fourth (L4), and fifth lumbar vertebrae were significantly lower in PPID+ equids as compared with aged (p<0. 001) and young (p<0.01) PPID controls. In contrast, no differences were found in BMD of trabecular...
Located in the lower back area, the lumbar region is the portion of the spine that begins below the shoulder blades, about five or six inches, at the lordosis (where it curves in toward the abdomen). There are five vertebrae that make up the lumbar spine, L1 through L5 – which also ...
(LACZ, a marker gene),BMP2,BMP7, a mixture ofBMP2andBMP7infected cells (homodimers, HM), orBMP2/7heterodimers (HT) were implanted into the discs between lumbar vertebrae 4 and 5 (L4/5) and L5/6 of male Lewis rats. Spine stiffening was monitored at 4, 8 and 12 weeks using non...

However, other future studies are needed to correlate the clinical significance of the anatomical variations and acquired osseous pathologies of the equine lumbar vertebrae. The radiographic, ultrasonographic, and scintigraphic findings of horses with thoracolumbosacral pain have been previously ...
vertebraemalformationA 5-day-old Friesian colt was presented with a history of severe bilateral pelvic limb weakness since birth. Clinical examination revealed a painful dorsal deviation of the spinous processes of the lumbar vertebrae, pelvic limb paraparesis and grade 4/5 ataxia. Radiographic ...
Like the thoracic and cervical vertebrae, the lumbars increase progressively in size from superior to inferior (L-1 to L-5). Lumbars are the largest of all the unfused vertebrae. Note that the individual illustrated in this manual has a sacralized L-5 with a pair of extra sacral ...
