"A number of parameters are useful :

• A good mortice view showing symmetrical reduction of the ankle mortice is essential.
• Anatomical reduction of the fibular fracture and restoration of fibular length should be confirmed.
• The stability of the syndesmosis can be tested directly once the fibular fracture has been fixed. This can be done using a small bone hook or a Homann retractor which is inserted into the syndesmosis and rotated. Any instability is readily appreciated.
• The medial mortice width should be less than 4mm.
• The talocrural angle, talar tilt angle and width of the syndesmosis 1cm above the joint can be compared to that of the opposite limb.
• The posterior edge of the tibia (reverse Tillaux fragment) should overlap the fibula by 6mm."
