Spine
Normal Spine
The illustration shows the curvature of a normal spine. Where any condition creates different curvature there will be a need for specialised seating solutions set out in the sections following dealing with Kyphosis, Lordosis, Scoliosis, Osteopourosis, Herniated discs and Exsostosis
- V1-V7 (C1 - C7) Cervical vertebrae
- V8-V19 (T1 - T12) Thoracic vertebrae
- V20-V24 (L1 - L5) Lumbar vertebrae
- 25 Sacrum
- 26 Coccyx
Kyphosis
Excessive backward curvature of the dorsal spine, commonly associated with Osteoporosis. The exaggeration of the posterior convexity of the thoracic vertibral column (humpback). It may be due to absence of a vertibral body (A); malformation by incomplete segmentation of vertibral bodies (B); the absence of a corner or flattening by compression (C). (D) is the porterior view of (C)
Lordosis
An exageration of the posterior concavity of the spine, characteristic of the lumbar region. Also called "swayback" indicating extreme anterior curvature of the lumbar region
Scoliosis
A condition involving lateral curve or angular deviation of one or more vertibral segments, often with a twisting of the spinal colunm
