📌 Trapped Periosteum in Pediatric Proximal Tibial Physeal Injuries

•  MRI guides surgical planning when conventional reduction fails, potentially improving outcomes.

 

✅ MRI Findings of Trapped Periosteum:

• widening of proximal tibial physis
• Enfolded periosteum in widened tibial physis
• Low signal intensity of trapped periosteum in growth plate

 

✅Benefits of MRI:

1. Evaluates menisci, ligaments, and articular cartilage
2. Assesses non-ossified epiphyses
3. Detects osteonecrosis and bony bridging
4. Identifies mechanical obstructions to the reduction
5. Visualizes periarticular structures (nerves, vessels, tendons, muscles)

 

---

✅ Type IV Fractures

• Type IV fractures present with fracture extension from the tibial tuberosity through the proximal tibial physis into the posterior tibial metaphyseal cortex.
