If the fracture is displaced, then it is often associated with other hindfoot injuries. This will lead to more decisions about further investigation and other forms of treatment.
Plain x-rays may be all that is required if the fracture is undisplaced. This, however, is unusual as most talar neck fractures present with at least some displacement.
CT examination is very helpful whenever there is any question about displacement, or requirement for debridement of the subtalar joint. Along the spectrum of injury, increasing displacement presupposes that there is more subtalar and tibiotalar osteochondral injury. This often requires surgical approaches for debridement and fixation of these fracture types.
