- Spinal fixation device redirects here.
Vertebral fixation (also known as "spinal fixation") is a neurosurgical procedure in which two or more vertebrae are anchored to each other through a synthetic "vertebral fixation device", with the aim of reducing vertebral mobility and thus avoiding possible damage to the spinal cord and/or spinal roots.
Vertebral fixation devices
The device used to achieve vertebral fixation is usually a permanent rigid or semi-rigid prosthesis made of titanium; examples include rods, plates, screws, and various combinations thereof. A much less common alternative is the use of a resorbable fixation device, composed of a bio-resorbable material; for example, this could be a polymer capable of being degraded into acidic products, and thus in need of including a buffering agent to avoid acid damage (which may damage the bone adjacent to the device).
