Targeted Relief for Spinal Nerve Root Pain With Image-Guided Precision
A Selective Nerve Root Block is a minimally invasive, fluoroscopy-guided injection used to target a specific spinal nerve root that may be contributing to radiating pain, numbness or other nerve-related symptoms. It may provide temporary pain relief and can also help your specialist identify whether a particular nerve root is contributing to your symptoms.
A Selective Nerve Root Block is an image-guided injection procedure used to target a specific spinal nerve root that may be responsible for radiating pain or other nerve-related symptoms.
Spinal nerve roots exit the spinal canal through openings called neural foramina. When a nerve root becomes irritated or compressed, it may cause pain that travels from the spine into an arm, hand, buttock or leg, depending on the level involved.
A nerve root may become irritated because of conditions such as a disc herniation, foraminal narrowing, degenerative spinal changes or other causes of nerve root irritation.
During the procedure, your pain specialist uses fluoroscopy, a real-time X-ray imaging technique, to identify the relevant spinal level and guide a fine needle toward the selected nerve root.
After confirming the needle position, a small amount of medication may be administered around the targeted nerve root. Depending on the purpose of the procedure and your individual condition, this may include a local anaesthetic and, when clinically appropriate, a corticosteroid.
The response to the injection may provide useful information about whether the targeted nerve root is contributing to your symptoms. In selected patients, the medication may also provide temporary relief from inflammation-related nerve root pain.
Your specialist reviews your symptoms, medical history, physical examination and relevant imaging to determine which nerve root may be contributing to your pain.
You are positioned appropriately on the procedure table to allow safe access to the selected spinal level and obtain the necessary fluoroscopic views.
Real-time X-ray imaging is used to identify the appropriate spinal anatomy and guide the needle toward the selected nerve root.
Once the needle position is confirmed, the selected medication is carefully delivered around the targeted nerve root.
The procedure focuses on a specific nerve root suspected to be contributing to your symptoms.
Medication delivered around the nerve root may provide temporary relief from inflammation-related radicular pain in selected patients.
Fluoroscopy provides real-time imaging to help guide the needle toward the intended spinal nerve root.
The patient's response may help the specialist assess whether the targeted nerve root is a likely contributor to the symptoms.
The procedure is performed with a fine needle rather than through open spinal surgery.
When pain is reduced, some patients may find it easier to participate in prescribed rehabilitation and activity.
A Selective Nerve Root Block may be considered when clinical assessment suggests that a particular spinal nerve root is contributing to your symptoms.
Your doctor may consider the procedure if:
A Selective Nerve Root Block may be considered when symptoms and clinical findings suggest that a specific spinal nerve root is contributing to radiating pain or other nerve-related symptoms.
A targeted cervical nerve root injection may be considered when a specific nerve root is suspected to be contributing to pain or sensory symptoms extending into the shoulder, arm or hand.
A lumbar selective nerve root block may be considered when a specific lumbar nerve root is suspected to be contributing to radiating pain into the buttock or leg.
When sciatica is associated with irritation of a particular lumbar or sacral nerve root, a targeted injection may be considered as part of the treatment plan.
A herniated or slipped disc can irritate a nearby nerve root. A selective nerve root block may be considered when clinical and imaging findings correspond to a specific nerve root.
Narrowing of the neural foramen can irritate or compress an exiting spinal nerve root. A targeted block may be considered in appropriately selected patients.
When symptoms suggest irritation of a specific spinal nerve root, a selective block may help assess the suspected pain generator and provide temporary symptom relief.
Your symptoms, examination findings and relevant investigations are assessed to identify the most likely nerve root involved.
Real-time X-ray imaging helps the specialist identify the appropriate spinal level and guide the needle toward the intended nerve root.
The procedure is planned around the specific nerve root suspected to be contributing to your symptoms.
Treatment planning takes into account your symptoms, diagnosis, previous treatment response and individual clinical needs.
Before your procedure, your pain specialist may:
Your doctor will determine whether a Selective Nerve Root Block is appropriate for your individual condition.
After the procedure, you may be monitored for a short period before discharge. Your post-procedure instructions will depend on the spinal level treated and the medications used.
You may be advised to:
Some patients may notice temporary pain relief soon after the injection because of the local anaesthetic. If a corticosteroid is used, its effect may take longer to develop. The degree and duration of improvement vary from person to person.
Selective Nerve Root Block is a minimally invasive procedure, but it can still have potential risks and side effects.
Possible complications include temporary soreness at the injection site, bruising, bleeding, infection, temporary numbness or weakness, nerve irritation and reactions to the injected medication.
Depending on the spinal level and medication used, other uncommon but potentially serious complications can occur. Your specialist will discuss risks that are relevant to your individual procedure.
Fluoroscopy uses ionizing radiation. The amount of radiation is kept as low as reasonably achievable while obtaining the imaging necessary for accurate needle placement.
A Selective Nerve Root Block does not remove an underlying disc problem, spinal stenosis or other structural cause of nerve irritation. It may provide temporary symptom relief and diagnostic information as part of a broader treatment plan.
Seek medical attention promptly if you develop severe or worsening pain, significant or persistent weakness, increasing numbness, fever, spreading redness or swelling, difficulty breathing, loss of bladder or bowel control, or other concerning symptoms following the procedure.
Radiating pain in the arm or leg can have several
possible causes. If your symptoms and clinical
assessment suggest involvement of a particular spinal
nerve root, a Selective Nerve Root Block may help
provide targeted treatment and useful diagnostic
information.
