3 LATERAL KNEE FRACTURES SEGOND ARCUATE AND LATERAL FIBULAR FRACTURES XRAY

• Avulsion Fracture of the lateral tibial plateau.
 

• Occurs at attachment site of the Antero Lateral Ligament.
 

• Posterior to IT B insertion site.
 

• Associated with ACL tears.

• Fracture of the Fibula Styloid (tip of the fibula).
 

• Site of attachment of Arcuate Complex.
 

• Predictor of Postero-Lateral Instability.
 

• Associated with PCL tears.
