Artificial Facet Replacement[edit]
Artificial facet replacement is a surgical procedure designed to replace the facet joints in the spine with artificial implants. This procedure is typically considered for patients suffering from severe facet joint syndrome, osteoarthritis, or other degenerative conditions that affect the facet joints, leading to chronic back pain and reduced mobility.
Anatomy of the Facet Joints[edit]
The facet joints, also known as zygapophysial joints, are a set of synovial, plane joints located between the articular processes of two adjacent vertebrae. These joints provide stability and facilitate movement in the spine, allowing for flexion, extension, and rotation. Each vertebra has two pairs of facet joints, one pair facing upward and the other downward, connecting with the adjacent vertebrae.
Indications for Artificial Facet Replacement[edit]
Artificial facet replacement is indicated in cases where conservative treatments, such as physical therapy, medication, and facet joint injections, have failed to alleviate symptoms. Conditions that may warrant this procedure include:
- Severe facet joint arthritis
- Degenerative spondylolisthesis
- Spinal stenosis
- Chronic facetogenic pain
Procedure[edit]
The procedure involves the surgical removal of the damaged facet joints and the implantation of artificial devices designed to mimic the function of natural facet joints. These implants are typically made from biocompatible materials such as titanium or polyethylene. The surgery is performed under general anesthesia and may involve a posterior or lateral approach to the spine.
Benefits and Risks[edit]
The primary benefit of artificial facet replacement is the potential for significant pain relief and improved spinal function. Patients may experience increased mobility and a reduction in the use of pain medications. However, as with any surgical procedure, there are risks involved, including:
- Infection
- Implant failure or displacement
- Nerve damage
- Adjacent segment disease
Recovery[edit]
Recovery from artificial facet replacement surgery involves a period of rehabilitation, including physical therapy to restore strength and flexibility. Patients are typically advised to avoid heavy lifting and strenuous activities for several weeks post-surgery.
