Extraforaminal Segmental Nerve Block
An extraforaminal segmental nerve block is a procedure used to diagnose and manage pain originating from a specific spinal nerve root. The procedure involves injecting a local anaesthetic and sometimes a steroid medication near the nerve as it exits the spine.
The term “extraforaminal refers” to the area outside the intervertebral foramen. The intervertebral foramen is the opening between two vertebrae through which spinal nerves exit the spinal cord.
The term “segmental nerve block” refers to injecting medication around a specific spinal nerve root. Each spinal nerve corresponds to a specific segment of the spinal cord, and blocking or numbing this nerve can help diagnose and alleviate pain associated with that segment.
The extraforaminal segmental approach is chosen when the pain is believed to originate from the nerve root as it leaves the spine but is not easily accessible through the traditional interlaminar or transforaminal approaches. This technique allows for more precise targeting of the affected nerve.
Conditions that may be treated or diagnosed with extraforaminal segmental nerve blocks include radiculopathy (pain radiating along the nerve pathway), disc herniation, spinal stenosis, and other nerve-related issues.
It’s important to note that while these nerve blocks can be effective in managing pain, they are often part of a comprehensive treatment plan, which may include physiotherapy, medication, and other interventions.
At RAD Clinics, we specialise in highly complex pain management procedures, unlike any other musculoskeletal service in the country. Our highly trained specialists still work in many NHS and private hospitals, performing more than 3000 guided pain relief injections that can range from simple soft tissue injections to very complex nerve block procedures.
Our “one-stop MSK appointment” includes consultation, diagnostic scan, and ultrasound-guided injection, if appropriate, in just one appointment. Our highly trained and skilled clinical team can help you by treating your condition swiftly and accurately through our “One-Stop MSK Appointments.”
