What is the treatment for a fractured talus?
Many talus fractures require surgery because of the high-energy force that creates the injury. Stable, well-aligned fractures, however, can often be treated without surgery. This is usually done with a combination of immobilization and then rehabilitation. Casting.
How do you prevent a talus fracture?
Anatomic reduction and restoration of the peritalar articular surfaces are the pillars of talar neck fracture treatment. Dual incision approach with plate and screw fixation has become the modern surgical strategy of choice to accomplish these goals.
What was the Hawkins classification of talar fractures?

What are the risks of a Hawkins fracture?
A Hawkins class II fracture is a displaced vertical talar neck fracture with a subluxation or dislocation of the subtalar joint and a 20–50% risk of AVN. A Hawkins class III fracture is a displaced fracture extending through the talar neck with dislocation at both the subtalar and tibiotalar joints and a 69–100% risk of AVN.
What does the Hawkins sign on a talus mean?
Hawkins sign (talus) This indicates that there is sufficient vascularity in the talus, and is therefore unlikely to develop avascular necrosis later 2,3. Disruption of the blood supply to all or a portion of the talar dome results in absence of the Hawkins sign (subchondral sclerosis), which usually indicates underlying avascular necrosis 4.
