Facet Joint Injection: Overview, Preparation, Procedure, Recovery, Risks, and Aftercare
Overview
Pain caused by the facet joints in the spine can be diagnosed and treated with facet joint injection, a minimally invasive procedure. Facet joints, located on the spine, can become inflamed or irritated, resulting in local or radiating pain. Injections of facet joints reduce inflammation and relieve pain by injecting medication directly into the affected joint.
Preparation
Before undergoing facet joint injection:
-
A thorough medical evaluation is conducted to assess the patient's overall health and suitability for the procedure. This may involve reviewing medical history, physical examinations, and imaging tests such as X-rays and MRIs.
-
To reduce bleeding risk or interference with injections, patients may be advised to temporarily discontinue certain medications, such as blood thinners or anti-inflammatory drugs, before the procedure.
Procedure
During the facet joint injection:
-
A procedure table is used to position the patient face down, and the skin overlying the targeted facet joint is cleaned and sterilized.
-
During the injection, a local anesthetic is administered to numb the skin and underlying tissues around the targeted facet joint.
-
Using fluoroscopy or ultrasound guidance, the healthcare provider locates the targeted facet joint and confirms its position before injecting it.
-
A mixture of anesthetics and anti-inflammatory medications, such as corticosteroids, is injected directly into the facet joint or the surrounding joint capsule to reduce inflammation.
-
After an injection, the patient may be observed for a short period to check for immediate adverse reactions.
Recovery
After facet joint injection:
-
The patient may be monitored for a short period after the procedure to ensure there are no immediate complications or adverse reactions.
-
After the injection, patients are typically advised to avoid strenuous activities and heavy lifting for a short period to allow the medication to take effect and minimize the risk of aggravating the treated area.
Risks
Facet joint injections are generally safe, but there are some risks and complications to consider:
-
There is a small risk of infection at the injection site, but proper sterilization techniques are used to minimize it.
-
Bruising or bleeding may occur at the injection site in some patients.
-
Rarely, patients may experience an allergic reaction to the medication injected.
Aftercare
After facet joint injection:
-
As the medication takes effect and reduces inflammation in the facet joint, patients may experience pain relief within a few days to a week following the injection.
-
A follow-up appointment may be scheduled to assess the effectiveness of the injection and to determine if additional treatments or interventions are necessary.
-
Depending on the patient's response to the injection and underlying condition, activity modifications, physical therapy, or additional interventions may be recommended.
A facet joint injection is an effective method for diagnosing and treating pain originating from the spine's facet joints. A facet joint injection can reduce pain and improve patient quality of life by delivering medication directly to the affected area. As with any medical procedure, it is imperative to weigh the potential benefits against the risks and to discuss any concerns with your doctor.
