MCQ Orthopedics Answer 8

The correct Answer is A

(Maheshwari 3rd,revised Ed., 139)

The following techniques of internal fixation are used in ankle fracture depending on the type of fracture:

1. Medial malleolus fracture:
· Transverse fracture-compression screw, tension band wiring
· Oblique fracture-compression screws
· Avulsion fracture-tension band wiring

2. Lateral malleolus fracture:
· Transverse fracture-tension band wiring
· Spiral fracture-compression screws
· Comminuted fracture-buttress plating
· Fracture of the lower third of fibula-4 hole plate

3. posterior malleolus:
· involving less than one third of the articulating surface of the tibia- no additional treatment
· involving more than one-third of the articulating surface of the tibia-internal fixation with compression screws.
· Tibio-fibular syndesmosis disruption-inserting a long screw from the fibula into the tibia.
