The probability of recovery from a fracture of the talus has no precise value and depends on the type of fracture, the degree of fracture displacement, and the degree of destruction of the surrounding soft tissues.
The main sources of blood supply to the talus are the arteries in the tarsal sinus and the blood vessels that enter the bone through the dorsal aspect of the talus neck. Thus a fracture of the talar neck may severely damage the blood vessels and affect the blood supply predisposing to ischemic necrosis.
For fractures of the posterior talar eminence and the head of the talus, displacement after fracture is not obvious, and both can recover after cast immobilization. For talar neck fracture without displacement, the recovery rate is greater than 90%, for fracture of the head of the talus, the recovery rate is greater than 60% after treatment; for dislocation of the talus by the ankle point and subtalar joint, the recovery rate is less than 10%.
The probability of recovery is relatively high with mild soft tissue damage around the talus fracture and no infection. If the soft tissue damage is severe, it can lead to infection and the chance of recovery becomes smaller.
A talus fracture requires active medical attention and physician-directed treatment.
