Fractures Of the Tibia in Children
Courtesy: Kaye Wilkins MD, Lynn Staheli MD Pediatric Tibial Fractures Proximal Tibial Metaphyseal Fracture Key complication Progressive valgus deformity (Cozen phenomenon). Cause Biological overgrowth is the most common cause. Increased vascularity produces greater medial than lateral growth. Not always related to inadequate reduction. Fibular tether theory is no longer accepted. Clinical features Valgus deformity […]
