Corticosteroids & Contrast Agents in Pain Management + Evidence-Based Steroid Selection

🔥 Episode Overview

In this high-yield episode of the PainExam Podcast, David Rosenblum breaks down a must-know board topic:

👉 Injectable corticosteroids vs contrast agents in interventional pain procedures

This episode goes beyond basics and dives into:

• Particulate vs non-particulate steroids
• Comparative profiles of dexamethasone, betamethasone, triamcinolone, and methylprednisolone
• Contrast agent selection and safety
• Critical complications including embolization and neurotoxicity
• A recent study comparing steroid effectiveness in transforaminal epidural injections

This is essential for physicians preparing for the ABA Pain Medicine boards and for clinicians performing spine interventions.

🧠 Core Concept

• Corticosteroids = therapeutic (reduce inflammation)
• Contrast agents = diagnostic + safety tools (confirm needle placement)

👉 Board pearl:
Steroids treat pain — contrast prevents complications

💉 Corticosteroids — High-Yield Comparison

🔬 Mechanism

• Inhibit phospholipase A2
• Reduce inflammatory mediators
• Decrease nerve root irritation

⚖️ Key Steroids Compared

🚨 Major Steroid Risks

Local:

• Tissue atrophy
• Depigmentation

Systemic:

• Hyperglycemia
• Adrenal suppression
• Immunosuppression

Catastrophic (Board Tested):

• Spinal cord infarction
• Stroke

👉 Caused by intra-arterial injection of particulate steroids

📊 Contrast Agents — High-Yield Review

Common Agents

• Iohexol (Omnipaque)
• Iopamidol (Isovue)
• Iodixanol (Visipaque)

🎯 Purpose

• Confirm needle placement
• Detect intravascular injection
• Prevent intrathecal injection

⚠️ Risks

• Allergic reaction
• Anaphylaxis
• Contrast-induced nephropathy

👉 Board pearl:
Shellfish allergy ≠ contrast allergy

⚠️ Critical Safety Topic: Gadolinium

Gadolinium-based contrast agents are:

❌ NOT approved for epidural or intrathecal use
❌ NOT safe substitutes for iodinated contrast in spine procedures

🚨 Intrathecal Gadolinium Risks

• Encephalopathy
• Seizures
• Respiratory distress
• Death

👉 Extremely high-yield board concept

📚 Evidence-Based Medicine Segment

Study Review: Steroid Selection in TFESI

A recent study comparing:

• Dexamethasone
• Methylprednisolone

🔑 Key Findings

• Dexamethasone showed comparable or better outcomes
• No clear advantage of particulate steroids
• Similar rates of:
  • Repeat injections
  • Surgical progression

🎯 Clinical Implication

👉 Efficacy differences are smaller than previously thought
👉 Safety is driving practice change

🚨 Board-Level Takeaway

• Non-particulate steroids = safer
• Outcomes ≈ similar
• Technique matters more than steroid choice

👉 Best exam answer: dexamethasone for TFESI

🎯 Board Prep Summary

• Dexamethasone = safest for transforaminal injections
• Particulate steroids = embolic risk
• Contrast must be used before steroid injection
• Gadolinium = dangerous in neuraxial space
• Clinical outcomes often similar across steroid types

Red Light Therapy (Photobiomodulation) for Pain

Evidence, Mechanisms, and Clinical Applications

Host: Dr. David Rosenblum

Red light therapy, also known as photobiomodulation (PBM) or low-level laser therapy (LLLT), is an emerging non-invasive treatment modality increasingly used in pain medicine, rehabilitation, and regenerative medicine practices.

In this episode of the PainExam Podcast, Dr. Rosenblum reviews the mechanisms, clinical evidence, indications, and safety considerations surrounding photobiomodulation therapy for pain.

Red and near-infrared wavelengths stimulate mitochondrial activity, increase ATP production, reduce inflammatory mediators, and promote tissue healing. These physiologic effects may translate into analgesic benefits for a variety of musculoskeletal and neuropathic pain conditions.

Clinical research suggests potential benefit in temporomandibular disorders, chronic neck pain, and inflammatory oral conditions, though results vary due to differences in dosing parameters and treatment protocols.

Despite these limitations, PBM has a favorable safety profile and is increasingly being integrated into multimodal pain management strategies.

Key Topics Covered

• What is photobiomodulation therapy (PBM)
• How red and near-infrared light interact with mitochondria
• Mechanisms of analgesia and tissue repair
• Evidence from clinical trials in TMD, neck pain, and oral inflammatory pain
• The biphasic dose response (Arndt-Schulz law)
• Safety profile and contraindications
• How PBM may integrate with regenerative pain medicine

Mechanism of Action

Photobiomodulation works primarily through stimulation of mitochondrial chromophores, particularly cytochrome c oxidase.

This leads to:

• Increased ATP production
• Modulation of inflammatory cytokines
• Increased angiogenesis and tissue repair
• Reduced oxidative stress

These effects may improve pain, inflammation, and healing in certain musculoskeletal conditions.

Dr. Rosenblum from NRAP Academy presented a webinar on the integration of regenerative medicine into pain practices, highlighting its benefits and applications. He discussed the evolution of treating pain, emphasizing the shift from neural blockade to addressing tissue health. Dave explained the use of PRP and BMAC in treating conditions like knee pain, and shared patient success stories. He addressed common misconceptions about regenerative medicine, including its cost and effectiveness. Dave also mentioned upcoming events and training opportunities in regenerative medicine.

Regenerative Medicine Pain Management Events

Dr. Rosenblum  announced his upcoming involvement in two significant events: a webinar on regenerative medicine for ASIPP and co-directing the ASPN Ultrasound and Regenerative Medicine Pain Workshop in Miami with Dr. Ali Valimoed. He encouraged attendees to register for these events, emphasizing their importance in the field of pain management. He also mentioned a previous lecture he gave on the integration of regenerative medicine into pain practices, though the recording was not successful.

Regenerative Medicine in Pain Practices

Dr. Rosenblum  discussed the integration of regenerative medicine into pain practices, emphasizing its importance in 2026 and beyond. He explained that traditional approaches like steroids and RFA only manage pain without addressing tissue health, using the knee as an example. He suggested combining visco supplements with regenerative techniques like PRP or BMAC to preserve joints in patients seeking alternatives to knee replacement. He noted that while other stem cell products are promising, more research is needed for wider adoption, and he plans to focus on PRP and BMAC for now.

Regenerative Medicine Patient Education

Dr. Rosenblum  discussed the importance of educating patients about regenerative medicine and pain treatment options. He explained that while regenerative treatments cannot fully reverse severe issues like meniscus damage, they can help heal and repair tissues, reduce inflammation, and improve function. He highlighted the growing demand for non-surgical, opiate-sparing solutions and mentioned the role of government and physician-led campaigns in addressing the opiate crisis.

PRP's Role in Chronic Pain Management

Dr. Rosenblum discussed the growing demand for alternative treatments to opioids and surgeries, highlighting the role of Platelet-Rich Plasma (PRP) in addressing chronic pain by modulating inflammation and stimulating tissue repair. He emphasized the importance of using high-quality PRP preparation methods, such as a double-spin kit, to achieve optimal results, and criticized studies claiming PRP's ineffectiveness, often due to poor preparation techniques. David also noted that effective PRP treatments can improve pain and function better than corticosteroids, and he expressed hope that patients would refer others, leading to business growth.

PRP Therapy: A Promising Alternative

Dr. Rosenblum discussed the effectiveness of PRP (platelet-rich plasma) therapy compared to steroids and viscosupplements in treating various musculoskeletal conditions. He cited a meta-analysis showing that PRP provided better relief than steroid and viscosupplement treatments for patients with moderate arthritis after one year. David also shared a recent case where he used PRP to treat coccydynia, a condition involving pain in the coccyx, and mentioned its potential use in treating other conditions such as radiculopathy and foraminal stenosis.

PRP Injection Treatment Flexibility

Dr. Rosenblum discussed a medical procedure involving PRP and lidocaine injections in various areas of the body, including the coccygeal ligaments, caudal space, and transforaminal spaces, to address pain and inflammation. He emphasized the importance of tailoring treatment to individual patients rather than adhering to insurance company guidelines, which can limit the number of injections given in a single session. David highlighted that when patients pay out-of-pocket, practitioners have more flexibility to effectively treat their conditions, potentially avoiding surgery or improving post-surgical outcomes.

PRP in Orthopedic Practice

Dr. Rosenblum shared his experience treating a patient with PRP for post-operative knee surgery, despite the orthopedic surgeon's skepticism. He discussed how regenerative medicine can enhance a practice by positioning it as innovative and attracting younger patients who prefer non-surgical treatments. David noted that while some orthopedic surgeons may refer patients for PRP, others might be hesitant due to potential decreases in surgical procedures. He also mentioned that primary care doctors may not be aware of the growing evidence supporting PRP's effectiveness and safety.

PRP: A Cost-Effective Alternative

Dr. Rosenblum discussed regenerative medicine, particularly PRP, highlighting its potential to avoid surgeries and improve patient satisfaction with an estimated 70% success rate. He emphasized the financial benefits for physicians, as it provides a cash stream with no need for prior authorizations or denials. David also addressed patient responsibility in healthcare costs, comparing the cost of regenerative treatments to other lifestyle expenses. He noted that while training is necessary, most interventional pain physicians possess the skills to administer PRP treatments.

PRP Treatment Success Stories

Dr. Rosenblum shared patient testimonials highlighting successful outcomes from PRP (platelet-rich plasma) treatments for various pain conditions, including shoulder, back, and neck issues. Patients reported significant improvements in pain relief and mobility, with some noting long-lasting effects beyond cortisone shots or surgery. David emphasized the importance of individualized treatment approaches and quality care, encouraging both patients and physicians to reach out for training and consultations. He concluded by inviting listeners to share the content with colleagues and patients, emphasizing the value of PRP treatments when done correctly.

Meralgia Paresthetica Education and the PM&R Boards

This podcast episode from the NRAP Academy features Dr. David Rosenblum discussing Meralgia Paresthetica, a mononeuropathy affecting the lateral femoral cutaneous nerve. The condition involves entrapment or compression of this purely sensory nerve as it passes under the inguinal ligament near the anterior superior iliac spine, causing burning pain, tingling, and numbness in the anterior lateral thigh.

Key clinical points covered include the nerve's L2-3 origin from the lumbar plexus, common causes such as obesity, tight clothing, pregnancy, and diabetes, and the absence of motor weakness or reflex changes. Diagnosis is primarily clinical, though ultrasound can visualize nerve entrapment effectively.

Treatment approaches range from conservative management including weight loss, avoiding tight clothing, physical therapy, and neuropathic pain medications (gabapentinoids, duloxetine, tricyclics) to interventional procedures. Dr. Rosenblu strongly advocates for ultrasound-guided nerve blocks over fluoroscopic or blind approaches, citing better visualization and reduced risk of nerve trauma. Advanced treatments mentioned include peripheral neuromodulation and cryoablation for refractory cases.

The episode emphasizes that this condition is commonly tested on pain management board examinations (ABA, ABPM, FIPP, osteopathic boards) and can be significantly more painful and disabling than typically appreciated.

Meralgia Paresthetica Education and Clinical Guidance

• Overview:
• Focused on definition, anatomy, diagnosis, management, and board exam relevance for meralgia paresthetica.
• Anatomy and Pathophysiology:
• Nerve: lateral femoral cutaneous nerve (sensory only), typically arising from L2–L3.
• Course: traverses across the iliacus, passes under or through the inguinal ligament just medial to the ASIS, then enters the thigh.
• Sensory distribution: anterolateral thigh; anterior cutaneous division extends toward the knee.
• Etiology and Risk Factors:
• Common contributors: obesity, tight belts or clothing, pregnancy, prolonged sitting, diabetes, prior pelvic or hip surgery.
• Entrapment site: under the inguinal ligament near the ASIS (most frequent).
• Clinical Presentation:
• Symptoms: burning pain, tingling, numbness, dysesthesia localized to the anterolateral thigh.
• Provocation/relief: worse with standing or walking; relief with sitting or hip flexion.
• Neurologic exam: no motor weakness; no reflex changes.
• Diagnosis:
• Primarily clinical; Tinel’s sign over the inguinal ligament may reproduce symptoms.
• EMG and nerve conduction studies are typically normal.
• Ultrasound: superficial nerve, generally easy to visualize, including in obese patients; can identify entrapment.
• Management Recommendations:
• First-line conservative care: weight loss; avoidance of tight belts/clothing; physical therapy; NSAIDs for inflammation.
• Pharmacologic options: gabapentin, pregabalin, duloxetine, tricyclic antidepressants; consider topical analgesic creams (e.g., lidocaine or anti-inflammatory combinations).
• Interventional approach:
• Ultrasound-guided nerve block is strongly recommended; the nerve lies lateral to the sartorius; real-time visualization enables precise, safe injection.
• Avoid fluoroscopic and blind approaches due to risk of further nerve trauma and post-procedure pain.
• Advanced interventions:
• Peripheral neuromodulation may provide benefit in select cases.
• Cryoablation has shown beneficial outcomes for the lateral femoral cutaneous nerve.
• Surgery is rarely required; options include neurolysis, decompression, or neurectomy as a last resort.
• Board Exam Preparation Emphasis:
• Key facts commonly tested:
• Involved nerve: lateral femoral cutaneous nerve.
• Nerve roots: L2–L3 (with population variants).
• Sensory-only nerve; absence of motor deficits.
• Compression site: under the inguinal ligament near the ASIS.
• First-line therapy: conservative measures; refractory cases: ultrasound-guided nerve block.
• Keywords to study: meralgia paresthetica; lateral femoral cutaneous nerve (also called lateral cutaneous nerve of the thigh).
• Practice Considerations:
• Severity: can be profoundly painful and disabling; often underappreciated.
• Referral: clinicians not trained in interventional techniques should refer patients to an interventionalist for diagnosis and treatment.

Decisions and Recommendations

• Ultrasound guidance is the preferred modality for lateral femoral cutaneous nerve interventions, superseding fluoroscopic or blind approaches.
• Rationale: superior visualization, real-time feedback, and reduced risk of nerve trauma and post-procedural pain.

Outreach and Resources
