A spine of a human being is made up of 33 vertebrae, discs, spinal cord and nerves, ligaments, and muscles. The spinal column is further divided into four regions, and the vertebrae within each region are numbered. The four regions in which your spinal column is divided are as follows: ...
The lumbar spine is composed of the lower 5 vertebrae, which have been numbered L1–L5. The lowest vertebra of the lumbar spine (L5) is connected to the top of the sacrum, which is a triangular bone present at the base of the spine fitting into the two pelvic bones. In some cases,...
Vertebrae are the33 individualbones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused. ...
from side to side, and rotate 180 degrees. There are 7 cervical vertebrae numbered C1 to C7. The vertebrae are separated by discs, which act as shock absorbers
Thelumbar spinenormally consists of five numberedvertebrae. Especially in youth, pairs ofzygapophyseal joints(facets) afford mobility in many different planes including flexion, extension, side bending, and rotation. Thevertebral bodiesare the heaviest components, connected by the relatively pliantinterver...
Tip: Maintain healthy spinal curves and keep your back in shape with correct posture and regular strength exercises targeting the back and abdominal muscles. Vertebrae As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx. Did ...
The section of the spinal column called the thoracic spine begins below the cervical spine (C7, neck), roughly at shoulder level and continues downward until it reaches the first level of the low back (L1, lumbar spine). Twelve vertebrae, numbered T1 through T12 from top to bottom, make ...
Moreover, correlating levels identified intraoperatively by fluoroscopy with inconsistently numbered vertebrae on preoperative MRI or CT is arduous. Errors in numbering can have devastating implications for patients. A simple and accurate vertebral numbering system that can be applied to routine imaging is...
9. An implant according to claim 1 wherein said implant is sized to be received with a bore formed between adjacent vertebrae of a human spine. 10. A spinal implant for insertion into a bore formed between adjacent vertebrae of a spine, the implant comprising: ...
Whether this increase in adjacent level deterioration is truly associated with rigid fusion, or if it is simply a matter of the individual patient's predisposition to degeneration is unknown. Either way, however, it is clear that a progressive fusion of a long sequence of vertebrae is undesirable...
