Tibial Plafond Anatomy

The tibial plafond lateral malleolus and medial malleolus form a mortise a socket in which the talus sits figure 2. Pilon fractures are caused by rotational or axial forces mostly as a result of falls from a height or motor vehicle accidents.

Anterior tibial artery.

Tibial plafond anatomy. Articulates with the talus and fibula laterally via the fibula notch. The cause of tibial plafond fracture is axial or rotational forces occurring from motor vehicle accidents or falling from a height. Tibial plafond fracture is an uncommon fracture occurring in the distal region of the tibia.

Especially vunerable over anteromedial tibia. Mechanism typically occurs as a result of an axial loading injury which drives the talus into the tibial. It is also known as pilon fracture and explosion fracture.

Soft tissues very poor thin skin absence of muscle and adipose tissue lack of deep veins. It involves the articular surface of the ankle joint. 11 originally proposed an anatomical nine zone grid scheme to the articular surface of the talus to more easily describe the location of an ocl and have also applied this to the articular surface of the distal tibial plafond figure 1.

Fracture of tibial weight bearing surface due to axial compression. Passes between 2 heads of tibialis posterior and interosseous membrane iom. These are considered to represent 1 10 of all lower limb fractures 6.

35 40 years. First branch of popliteal artery. Up to 50 incidence of associated injuries.

1 a pilon fracture also called a plafond fracture is a fracture of the distal part of the tibia involving its articular surface at the ankle joint. Rapid axial load very high energy. Although the ligaments are needed to give the ankle its full stability the bony congruity of the mortise and the talus is a necessary component as well forming the most congruent joint in the lower extremity.

Tibial plafond fractures introduction. A pilon fracture is a type of fracture involving the distal tibia.

The distal portion of the tibia is known as the plafond which. Radiographic examination of the ankle bones. Plafond fractures are infrequent injuries accounting for 7 10.
