In tibial plateau fractures, the Schatzker classification is widely used. Which Schatzker type carries the highest risk of associated neurovascular and ligamentous injuries and requires the most complex surgical management?
- A Schatzker Type I (lateral split)
- B Schatzker Type II (lateral split-depression)
- C Schatzker Type IV (medial condyle fracture)
- D Schatzker Type VI (bicondylar + metaphyseal-diaphyseal dissociation) ✓
Explanation
Schatzker Type VI is the most severe tibial plateau fracture, involving bicondylar fracture with complete separation of the tibial metaphysis from the diaphysis. It results from high-energy trauma (axial loading + varus/valgus), carries the highest rates of vascular injury (popliteal artery), soft tissue stripping, compartment syndrome, and ligamentous disruption. Management requires temporary spanning external fixation to restore length and allow soft tissue swelling to subside, followed by ORIF via dual incisions at 10–14 days. Type IV (C) also carries significant risks due to medial comminution and instability but is less complex than VI.
