vertebral fixation is a spinal surgical procedure in which two or more vertebrae are fused together by special instrumentation for stabilization and decrease mobility at this segment to prevent injury of spinal cord or nerve roots at this levels.
It is indicated for management of: fracture spine (traumatic or pathological), spinal deformity as kyphosis or scoliosis, spondylolysis and spondylolisthesis.
The device used to achieve vertebral fixation is usually a permanent rigid prosthesis made of titanium; examples include rods, plates, screws, and various combinations. A cages can be used as alternative in interbody fusion; also synthetic bone is used to promote the vertebral fusion.
A spinal fixation device stabilizes an area of the posterior spine while allowing for a significant range of motion and limiting the compression of the affected vertebrae.
The medical community uses several different techniques for stabilizing the posterior region of the spine: traditional (open) surgery and percutaneous spinal fixation which is considered as minimal invasive surgery whereit implies a lack of severe surgical invasion. The older style of open-spine surgery require large incision and longtime staying in the hospital.
Percutaneous spinal fixation utilizes more modern technology, advanced imaging techniques and special medical equipment to reduce tissue trauma, bleeding, radiation exposure, infection risk, and decreased hospital stays by minimizing the size of the incision.
