Chronic low back and neck pain can be debilitating, significantly impacting daily life. Fortunately, the field of interventional pain management is rapidly advancing, offering innovative and precise techniques to alleviate discomfort. As of 2025, these therapies increasingly focus on minimally invasive approaches, targeting the specific source of pain, promoting the body's natural healing, and reducing reliance on long-term medication. This overview explores the cutting-edge treatments that are redefining how we address spinal pain.
Neurostimulation involves using electrical impulses to modulate nerve activity and interrupt pain signals. This field has seen remarkable progress, offering hope for patients with chronic, intractable pain.
Addressing chronic back pain with advanced interventional therapies.
SCS involves implanting a small device, similar to a pacemaker, that delivers mild electrical impulses to the spinal cord via thin wires called leads. These impulses interfere with the transmission of pain signals from the spinal cord to the brain, replacing the sensation of pain with a more tolerable tingling (paresthesia) or, with newer systems, no sensation at all (paresthesia-free stimulation). Recent advancements in 2025 include smaller, more energy-efficient devices, wireless programming, and sophisticated algorithms that allow for personalized stimulation patterns that can adapt to a patient's activity levels and pain fluctuations. SCS is particularly effective for chronic neuropathic pain, such as that experienced after back surgery (Failed Back Surgery Syndrome) or complex regional pain syndrome, and is typically considered when more conservative treatments have failed.
The "injectrode" represents a significant step towards less invasive neuromodulation. This innovative technology involves a thin, flexible lead wire that can be injected through a needle near an injured or painful nerve. Once in place, it delivers targeted electrical stimulation. Human safety and efficacy trials have shown promising results for this technique, offering a potential alternative to traditionally implanted leads for chronic pain, particularly in peripheral nerve conditions. Its minimally invasive nature means a quicker procedure and potentially fewer complications.
The ReActiv8 system takes a unique approach by targeting a root cause of some chronic low back pain: dysfunction of the lumbar multifidus muscle. This deep spinal muscle is crucial for stabilizing the lumbar spine. In many chronic low back pain sufferers, this muscle can become atrophied and weak. The ReActiv8 device is implanted and delivers electrical stimulation to activate and recondition the multifidus muscle. By restoring its strength and control, the system aims to improve spinal stability and thereby reduce chronic low back pain. This restorative neurostimulation is distinct from methods that simply block pain signals.
While not strictly "interventional" in the same way as implanted devices, TENS units are an important part of the broader pain management toolkit. These battery-operated devices deliver low-voltage electrical impulses to the skin via electrodes placed over painful areas. Advancements have made TENS units more portable, user-friendly, and with more customizable programs, making them a convenient option for at-home management of both neck and back pain.
Ablation techniques involve using energy (like heat or cold) to intentionally damage or destroy specific nerve tissues that are transmitting chronic pain signals. These procedures are highly precise, thanks to advanced imaging guidance.
The Intracept procedure is a groundbreaking, minimally invasive therapy specifically designed for chronic low back pain originating from the vertebral endplates – known as vertebrogenic pain. This type of pain is often associated with degenerative changes in the vertebrae. The procedure involves inserting a specialized probe into the vertebral body under fluoroscopic (X-ray) guidance and delivering radiofrequency energy to ablate (or "deaden") the basivertebral nerve. This nerve transmits pain signals from the damaged endplates. Clinical studies have shown that Intracept can provide significant and durable pain relief for patients with specific MRI findings indicative of vertebrogenic pain, potentially avoiding more invasive surgical options.
RFA is a well-established interventional technique used for various chronic pain conditions, including facet joint pain in the neck (cervical) and low back (lumbar), as well as sacroiliac joint pain. It uses heat generated by radiofrequency waves to create a lesion on specific nerves, thereby interrupting pain signals. The procedure is performed under image guidance (fluoroscopy or ultrasound) to ensure accurate targeting of the medial branch nerves (for facet joints) or lateral branch nerves (for sacroiliac joints). Latest trends focus on enhanced imaging for even greater precision and improved probe technology for optimal lesion creation, leading to longer-lasting pain relief.
Cryoanalgesia, or cryoneurolysis, utilizes extreme cold to temporarily disable pain-transmitting nerves. A cryoprobe is guided to the target nerve (again, using imaging), and cooled to temperatures that freeze the nerve, causing a reversible disruption of its function. This can provide pain relief for several months as the nerve slowly regenerates. It's considered a less destructive alternative to RFA in some cases and can be used for various types of nerve pain in the back and neck.
Regenerative medicine aims to repair or replace damaged tissues using the body's own healing capabilities. These therapies are increasingly integrated into interventional pain management for conditions affecting the spine.
Understanding and treating various causes of neck pain.
PRP therapy involves drawing a small sample of the patient's blood, processing it to concentrate the platelets, and then injecting this platelet-rich plasma into damaged tissues such as degenerated spinal discs, ligaments, tendons, or facet joints. Platelets are rich in growth factors that can stimulate tissue repair, reduce inflammation, and modulate pain. PRP injections are performed under image guidance for precision and are gaining traction for their potential to provide long-term relief by addressing the underlying tissue damage contributing to low back and neck pain.
Stem cell therapy involves harvesting stem cells (often from the patient's own bone marrow or adipose tissue) and injecting them into damaged areas of the spine. These cells have the potential to differentiate into various cell types and promote tissue regeneration, reduce inflammation, and release factors that can alleviate pain. While still an area of active research with evolving protocols, stem cell therapy holds promise for treating conditions like degenerative disc disease. As of 2025, it is becoming more refined and accessible, though patients should seek treatment from reputable centers with expertise in these procedures.
The trend towards less invasive solutions continues with refined surgical techniques and more precise methods for delivering therapeutic agents.
The MILD procedure is an outpatient, minimally invasive treatment primarily for lumbar spinal stenosis (LSS) caused by a thickened ligamentum flavum (a ligament in the spinal canal). LSS can cause pain, numbness, and weakness in the legs. During the MILD procedure, specialized tools are used through a tiny incision (about the size of a baby aspirin) to remove small portions of the thickened ligament and bone, creating more space for the spinal nerves. This decompression can alleviate pain and improve function. It has gained Medicare coverage for appropriate patients and is valued for preserving spinal stability.
Biportal endoscopic spine surgery is a state-of-the-art minimally invasive technique that uses two small incisions (portals) and an endoscope (a thin tube with a camera and light) to visualize and treat spinal conditions like herniated discs and spinal stenosis in both the lumbar and cervical spine. This approach allows surgeons to perform decompressions and discectomies with minimal tissue disruption, leading to faster recovery times, less post-operative pain, and smaller scars compared to traditional open surgery.
ESIs involve injecting corticosteroid medication, often mixed with a local anesthetic, into the epidural space around the spinal nerves. This helps reduce inflammation and alleviate pain, particularly radicular pain (pain that radiates down an arm or leg) caused by conditions like herniated discs or spinal stenosis. While widely used, recent guidelines emphasize their role primarily for short-term relief of acute radicular pain. Image guidance (fluoroscopy or ultrasound) is crucial for accurate placement and safety. Selective Nerve Root Blocks (SNRBs) are similar but involve injecting medication around a specific nerve root. They are often used diagnostically to pinpoint the exact source of pain, and can also provide therapeutic relief.
Precision in action: A cervical epidural steroid injection, a common interventional technique for neck pain.
Epidurolysis, also known as the Racz Procedure, is an interventional technique used to treat chronic back or neck pain often caused by epidural scarring (adhesions), typically after previous spine surgery. It involves inserting a special catheter into the epidural space under fluoroscopic guidance. The catheter is used to mechanically break down scar tissue and deliver medications like local anesthetics, steroids, and hypertonic saline to reduce inflammation and pain.
For severe chronic pain that hasn't responded to other treatments, an intrathecal drug delivery pump may be an option. This system involves a surgically implanted pump that delivers small, precise doses of pain medication (like morphine or baclofen) directly into the intrathecal space (the fluid-filled area surrounding the spinal cord). This allows for potent pain relief with much smaller doses than oral medications, reducing systemic side effects. Newer pumps offer improved programmability and longevity.
