Treatment of Bone Marrow Contusion in Pediatric Patients
Bone marrow contusions in pediatric patients are self-limiting injuries that require conservative management with rest, activity modification, and symptomatic pain control—no specific medical or surgical intervention is indicated.
Understanding Bone Marrow Contusions
Bone marrow contusions represent traumatic bone injuries visible on MRI that result from compressive forces between adjacent bones, direct blows, or traction forces during injury 1. These injuries appear as areas of bone marrow edema on MRI and serve as a "footprint" indicating the mechanism of injury 1. In pediatric patients, MRI is particularly sensitive for diagnosing bone marrow contusions and assessing associated physeal injuries 2.
Primary Management Approach
Conservative Treatment
- Rest and activity modification form the cornerstone of management, as bone marrow contusions heal spontaneously over time without specific intervention 3, 1
- Weight-bearing restrictions should be implemented based on the location and severity of the contusion, particularly for lower extremity injuries 3
- Gradual return to activity as symptoms improve, typically over 6-12 weeks
Pain Management
- Acetaminophen or NSAIDs for mild to moderate pain as first-line analgesics
- Opioid medications may be considered for severe pain, though this is rarely necessary for isolated bone marrow contusions 4
- Pain severity typically correlates with the extent of bone marrow edema and associated soft tissue injuries 1
Critical Diagnostic Considerations
Associated Injuries
The pattern of bone marrow contusion predicts specific soft-tissue injuries that require identification and management 1:
- Pivot shift pattern (posterolateral tibial plateau and midlateral femoral condyle): Associated with ACL tears 3, 1
- Dashboard injury (anterior proximal tibia): Associated with PCL tears 1
- Clip injury (lateral and medial femoral condyles): Associated with MCL tears 1
- Hyperextension pattern (anterior tibia and distal femur): Associated with ACL and posterior capsule injuries 1
When to Investigate Further
Do not assume an isolated bone marrow contusion—always evaluate for ligamentous, meniscal, and cartilage injuries that may require specific treatment 3, 1. MRI without contrast is the preferred modality for comprehensive assessment of both osseous and soft-tissue pathology in the acute trauma setting 2.
Common Pitfalls
- Failing to identify associated ligamentous injuries: The bone marrow contusion pattern should prompt systematic evaluation for predictable soft-tissue injuries 1
- Premature return to activity: Bone marrow edema may persist for weeks to months on MRI even after clinical symptoms resolve 3
- Unnecessary invasive procedures: Bone marrow contusions do not require aspiration, biopsy, or surgical intervention—these are imaging findings that heal with conservative management 3, 1
