THE PALM BEACH REGENERATIVE APPROACH TO BACK PAIN
We Don’t Just Treat the Disc. We Treat the Whole Spine.
Most back pain is not a single-structure problem, and treating it like one is why so many patients cycle through injections, therapy, and even surgery without lasting relief. At Palm Beach Regenerative, every back pain patient is evaluated through the lens of the Functional Spinal Unit (FSU), the complete biomechanical system responsible for your spine’s stability, movement, and pain signals. We identify every contributing structure, then treat precisely what needs treating, guided in real time by imaging.
Results vary. Not all patients are candidates. Dr. Ghattas will discuss realistic expectations for your specific condition.
| Approach | What it targets | What it misses |
|---|---|---|
| Epidural steroid injection | Nerve root inflammation | Disc, facets, ligaments, multifidus |
| Discectomy / microdiscectomy | Herniated disc fragment | Facets, ligaments, multifidus, adjacent segments |
| Spinal fusion | Instability at one segment | Adjacent segment overload, multifidus, SI joints |
| FSU approach (PBRSS) | All contributing structures — disc, facets, ligaments, nerves, multifidus, SI joints | Nothing |
CONDITIONS WE TREAT
Back conditions addressed through the FSU approach
Each condition below has its own dedicated page. All are evaluated and treated within the FSU framework — meaning no condition is viewed in isolation. Click any condition to learn more.

THE PBRSS APPROACH
What sets our back pain approach apart
| Outcome tracking via Regenexx registry | Structured follow-up at 6 weeks, 3 months, 6 months, and 12 months. We measure what we do and adjust based on your individual response — not protocol alone. |
| Double board-certified neurologist | Dr. Ghattas's neurology training adds clinical depth for the nerve root, spinal cord, and radiculopathy components that a standard pain management approach may underweight. |
| Honest about surgery | When surgery is the right answer, Dr. Ghattas will tell you — and refer you to an excellent surgical specialist. The goal is your outcome, not the procedure count. |
| Every injection image-guided | Real-time ultrasound and fluoroscopy guidance ensures accurate delivery to the exact target. Not approximate — confirmed before every injection. |
The Foundation
What is the Functional Spinal Unit (FSU)?
The Functional Spinal Unit is the smallest segment of the spine that replicates the mechanical behavior of the entire spinal column. Each FSU consists of two adjacent vertebrae and all the structures that connect them: the intervertebral disc, paired facet joints, anterior and posterior ligaments, nerve roots, and the deep stabilizing muscles, particularly the multifidus. These structures do not work in isolation. When one fails, the others compensate and often become painful themselves.
This is why treating “the disc” alone, or blocking “the nerve” alone, rarely resolves chronic back pain. The disc may be the visible finding on MRI, but the facet joints, ligaments, and destabilized multifidus are equally involved in generating and perpetuating the pain. The FSU approach means we look at all of them.
THE FSU COMPONENTS
What we evaluate and treat in every back pain patient
1) Intervertebral Discs
The disc is the most recognized source of back pain, but disc pathology (herniation, degeneration, annular tears) is rarely the whole story. We assess disc health as part of the FSU and treat the disc-adjacent environment in most cases. Direct disc injection is reserved for carefully selected cases only.
2) Lumbar Facet Joints
The most common source of axial low back pain, often responsible even when the MRI highlights a disc. Ten facet joints in the lumbar spine guide every movement. Image-guided PRP or prolotherapy to the facet joint capsules is typically the primary treatment target in our lumbar FSU approach.
3)Spinal Ligaments
The interspinous, supraspinous, and iliolumbar ligaments stabilize each lumbar segment. Ligament laxity allows excessive motion, a key driver of chronic instability pain that is almost never addressed by conventional treatments.
4) Nerve Roots and Epidural Space
When a disc herniation, bone spur, or stenosis compresses a nerve root, the result is sciatica, radiating leg pain, numbness, or weakness. Image-guided epidural PRP and perineural hydrodissection address the inflammatory environment around the affected root.
5) Multifidus Muscle
The deepest spinal stabilizer, and the one most consistently atrophied in chronic back pain patients. Multifidus atrophy is visible on MRI and represents both a cause and a consequence of spinal instability. No injection-based treatment is complete without addressing this structure through targeted rehabilitation.
6) Sacroiliac Joints
Frequently overlooked, the SI joints are a significant source of low back, buttock, and posterior thigh pain. They are co-treated with the lumbar FSU when dysfunction is identified, because untreated SI joint instability undermines any lumbar treatment.
Why it matters
The problem with single-structure thinking
Standard pain management targets the most visible finding on MRI, usually the disc. Epidural steroid injections dampen inflammation around the nerve, and discectomy removes the offending disc fragment. These approaches can help, and Dr. Ghattas will tell you honestly when they are the right choice. But for patients with chronic, recurrent, or multi-level back pain, single-structure treatment often provides temporary relief because it leaves the rest of the FSU, the facets, ligaments, and multifidus, untreated and unstable.

Honest about surgery
When surgery is the right answer, Dr. Ghattas will tell you — and refer you to an excellent surgical specialist. The goal is your outcome, not the procedure count.
Ready to understand the real source of your back pain?
Dr. Ghattas will review your imaging and assess your lumbar spine as a complete system, then discuss which structures are contributing and whether orthobiologic treatment is appropriate for your specific case.
FDA/FTC Compliance Note: Per Regenexx guidelines, never claim to regenerate or rebuild discs. The majority of spine procedures use PRP, not BMC. Direct disc injection is performed only in carefully selected cases. Always qualify outcomes (many patients experience improvement) and acknowledge when surgery is more appropriate.
Like all medical procedures, orthobiologic treatments have potential risks and benefits and results vary by individual. Not all patients are candidates. The majority of spine procedures use platelet-rich plasma (PRP) rather than bone marrow concentrate. These treatments do not regenerate or rebuild damaged discs or spinal structures. Dr. Ghattas will discuss your specific situation, realistic expectations, and all options, including when surgical referral is more appropriate.
