[Pilon tibiale fractures].
In the AO classification, the distal tibia is 43 and A type injuries are extra-articular, B type partial articular and C type involve the whole of the articular surface with complete separation of the joint from the diaphysis. The term pilon fracture should be confined to B(3) and C type fractures. The injury mechanism of pilon fractures will vary from a simple fall to a high energy road traffic accident, leading to increasing fracture comminution and greater soft tissue injury with more open fractures. Plain radiographs and CT-scans are diagnostic prerequisites. A spanning external fixator, with or without fixing the fibula, is the initial method of choice. The goal is to span the zone of injury with the fixator, to align the limb, to reduce the articular surface through very limited approaches, and to minimize complications related to treatment to maintain length and provisionally align the fracture. When soft tissue swelling has subsided definitive stabilization is performed. Bone grafting of defects is rarely necessary.
