Total talar dislocation

Dr Henry Knipe and Dr Ayush Goel et al.

Total talar dislocation, also known as extrusion of the talus, is a tri-articular dislocation of talus at the tibiotalar, talonavicular and subtalar joints. Most injuries are compound.

Total talar dislocation is a rare injury caused by the combination of tibiotalar plantar flexion, and either excessive subtalar supination or pronation (commonly from motor vehicle accident or fall from height). It results in complete disruption of blood supply and extensive contamination.

The classic scenario is a high energy motor vehicle accident where the driver's foot is plantarflexed, such as when rapidly applying the foot brake, causing the talus to extrude anteriorly. If a severe open injury results, the talus may be found in the foot well of the driver's compartment.

Dislocation of the talus from the mortise joint above, the subtalar joints below and the talonavicular joint anteriorly. The talus usually extrudes anteriorly. There is usually extensive soft tissue injury.

  • if unable to find talus, tibiocalcaneal fusion and fibular graft is a surgical option
