Normal anatomy:
The vertebrae are the bones that make up the spinal column, which surrounds and protects the spinal cord. The intervertebral discs are soft tissues that sit between each vertebrae and act as cushions between vertebrae, and absorb energy while the spinal column flexes, extends, and twists. Nerves from the spinal cord exit the spinal column between each vertebra.
Indications:
Spinal fusion may be recommended for:
- Abnormal curvature of the spine: (scoliosis or kyphosis)
- Injury to the spinal vertebrae
- Protrusion of the cushioning disc between vertebrae (slipped disc, herniated nucleus pulposus)
- Weak or unstable spine caused by infections or tumors
