Intraosseous BMC

Intraosseous (IO) injections represent an advanced Regenexx technique that addresses pain and pathology beneath the cartilage surface – directly within the bone. Many patients with joint pain have bone marrow lesions (BMLs) visible on MRI that contribute significantly to symptoms yet are inaccessible to traditional treatments.

At Palm Beach Regenerative, Dr. Ghattas uses precision fluoroscopic guidance to deliver therapeutic biologics directly into these bone lesions, targeting an often-overlooked source of joint pain.

Bone is highly innervated, so BMLs cause significant pain that standard intra-articular injections cannot adequately address.

Understanding Bone Marrow Lesions:

MRI imaging may reveal areas of bone marrow swelling and inflammation (bone marrow lesions or BMLs) in joints affected by:

• Osteoarthritis
• Stress reactions
• Avascular necrosis (early stages)
• Post-traumatic changes
• Overload and repetitive stress

The Procedure:

1. Fluoroscopic Guidance
   Under continuous X-ray guidance, Dr. Ghattas:
   • Advances a specialized needle through skin to bone surface
   • Penetrates cortical (outer) bone layer
   • Enters bone marrow cavity at lesion site
   • Confirms position with contrast dye
   • Injects therapeutic biologic preparation
   • May treat multiple lesion sites if needed
2. What We Inject:
   • Bone marrow concentrate (contains cells that may support bone healing)
   • Platelet preparations
   • Combinations based on individual assessment

These preparations aim to support your body’s healing response in bone, reduce inflammation within bone marrow, promote resolution of bone marrow lesions, and improve bone health.

Total Time: Plan for 2-2.5 hours

Bone Marrow Lesions:

• BMLs associated with knee osteoarthritis
• BMLs in hip, ankle, or other joints
• Post-traumatic bone bruising and swelling
• Stress reactions in bone

Early Arthritis with Bone Involvement:

• Arthritis with significant bone pain component
• Subchondral bone plate changes
• Bone overload from malalignment

Other Bone Conditions:

• Early avascular necrosis (limited cases)
• Bone cysts or lesions (select cases)
• Failed cartilage-only treatments

Direct Bone Treatment:
Unlike intra-articular injections (into joint space), IO injections treat the bone directly where pain originates.

Targets Hidden Pain Source:
Many patients have significant bone pathology missed by cartilage-focused treatments.

Advanced Regenexx Technique:
Requires specialized training, equipment, and fluoroscopic skills. Not widely available.

Comprehensive Joint Treatment:
Often combined with intra-articular injection for complete joint treatment:

• IO injection for bone marrow lesions
• Intra-articular for cartilage and joint lining
• Addresses multiple pain sources in one session

Immediate (Day 0-3):

• Post-procedure bone pain expected (drilling into bone causes soreness)
• May be more uncomfortable than standard injections
• Ice, rest, and pain management as directed
• Avoid weight-bearing on affected limb as directed
• Avoid anti-inflammatory medications

Early Phase (Week 1-4):

• Gradual reduction in post-procedure soreness
• Protected weight-bearing continues
• Begin gentle range of motion
• Some patients notice early improvement

Healing Phase (Week 4-12):

• Bone healing and remodeling occurs
• BML resolution may be visible on follow-up MRI
• Progressive improvement in pain and function
• Gradual return to activities

Maturation Phase (3-6 months):

• Continued bone remodeling
• Maximum benefit often at 6 months
• Follow-up MRI may show BML improvement
• Long-term activity modifications discussed

Activity Restrictions:

• Protected weight-bearing: 2-6 weeks (varies by joint and lesion)
• Avoid high-impact activities: 8-12 weeks
• Gradual return to sport/activities
• Joint protection and alignment correction important

For appropriately selected patients with bone marrow lesions, many report:

• Significant reduction in deep, aching bone pain
• Improved function and weight-bearing tolerance
• Enhanced response to overall joint treatment
• MRI evidence of BML improvement (in many cases)

Important Factors:

• Size and number of BMLs
• Underlying cause of bone pathology
• Overall joint health
• Concurrent treatments
• Activity modifications

Realistic Expectations:

• Bone healing takes time (months)
• Some BMLs respond better than others
• Not all bone pain is from BMLs
• May need to address underlying biomechanical issues
• Some patients ultimately need surgery for advanced arthritis

May be appropriate when:

• MRI shows bone marrow lesions contributing to pain
• You have significant bone pain component (deep, aching)
• Cartilage-focused treatments haven’t fully addressed symptoms
• You want comprehensive joint treatment
• Early arthritis with bone involvement

Often combined with:

• Intra-articular orthobiologic injection
• Realignment procedures if malalignment present
• Physical therapy for joint protection
• Activity modification and biomechanical correction

May NOT be best choice when:

• No BMLs identified on MRI
• Severe, end-stage arthritis (surgery likely better)
• Active infection in joint or bone
• Contraindications to bone injection

• Advanced Regenexx technique
• Fluoroscopic precision guidance
• Fellowship-trained physician
• Often combined with intra-articular injection
• Comprehensive joint treatment approach
• Systematic outcome tracking
