Selective nerve root blocks (SNRBs) are a medical procedure used primarily to assess and alleviate pain that originates from specific nerve roots in the spine. This advanced technique allows for effective diagnosis and treatment of various pain-related conditions, providing relief for patients suffering from chronic pain syndromes.
At Trinity Surgical Center in San Jose, CA, we specialize in offering comprehensive pain management solutions tailored to our patients’ unique needs.
Exploring Selective Nerve Root Blocks
According to the Techniques in Vascular and Interventional Radiology journal, “Selective nerve root blocks are an effective way of diagnosing and treating radicular pain in many patients. Although traditionally performed under fluoroscopic guidance, computed tomography (CT) and CT fluoroscopy have been increasingly used to direct needle placement.”
They involve injecting a local anesthetic, often combined with a steroid, into the region surrounding a specific nerve root in the spine. This procedure can help determine the source of radicular pain—pain that radiates along the path of a nerve due to injury or irritation. By temporarily blocking the nerve root, physicians can evaluate whether the pain relief is attributable to that specific nerve, aiding in the diagnosis and treatment planning for conditions like herniated discs, spinal stenosis or nerve compression syndromes.
Locations in the Body Where Selective Nerve Root Blocks Provide Relief
Selective nerve root blocks are primarily performed on the cervical (neck) and lumbar (lower back) regions of the spine. In these areas, nerve roots can frequently become compressed or irritated, leading to pain that radiates into the arms or legs.
- Cervical Spine: Patients experiencing radicular pain in the neck that may radiate into the shoulder, arm or hand may benefit from SNRBs in the cervical spine. Conditions like herniated cervical discs, cervical spondylosis or cervical radiculopathy are common reasons for this procedure.
- Lumbar Spine: SNRBs are also effective for people suffering from lower back pain that radiates into the buttocks, thighs or legs. Conditions such as lumbar disc herniation or sciatica due to nerve root compression are often treated through this approach.
Leading Cases for Recommendation
A neurologist or pain management specialist may recommend selective nerve root blocks for various reasons:
- Diagnosis: When the source of pain is uncertain, SNRBs can help localize the nerve root responsible for the symptoms.
- Treatment of Radicular Pain: In cases where conservative treatments (like physical therapy or medication) have failed, SNRBs can provide significant, albeit temporary, relief from pain.
- Assessment Prior to Surgery: If surgical intervention is being considered, SNRBs can confirm the diagnosis and justify the need for more invasive procedures.
- Post-surgical Pain: For patients recovering from spine surgery, SNRBs may help relieve residual pain in specific areas.
- Adjacent Segment Disease: Those who have undergone previous spinal surgery may experience pain in adjacent segments, which can sometimes be treated effectively with SNRBs.
FAQs on Selective Nerve Root Blocks
How long does the procedure take?
The actual injection procedure typically takes 15 to 30 minutes. However, due to pre-procedural preparations and post-procedural monitoring, the total time at our facility may be longer.
Is the procedure painful?
Patients may experience some discomfort from the needle insertion, but the use of a local anesthetic helps to minimize this. Many people report that the pain relief achieved is well worth the minor discomfort.
How long will the effects last?
The duration of pain relief can vary widely among patients, ranging from days to several months, depending on the individual’s condition and response to the injection.
Are there any risks associated with selective nerve root blocks?
While SNRBs are generally safe, potential risks include infection, bleeding, nerve damage or allergic reactions to the medications used. Our skilled medical team at Trinity Surgical Center carefully reviews these risks with each patient prior to the procedure.
What should I expect after the procedure?
Most patients are monitored for a short time after the procedure and encouraged to rest. You may experience soreness at the injection site, but any pain should improve significantly.
