Computed tomographic evaluation of calcaneal fractures.
Computed tomography (CT) can be a useful adjunct to conventional radiographs in the evaluation and treatment planning of comminuted calcaneal fractures. Either a combination of direct coronal and axial scan planes or a single set of oblique images may be used to study the calcaneus. CT can show the fracture planes, including the amount of displacement of fracture lines entering the posterior subtalar facet and the relationship of the sustentaculum tali to the remainder of the bone. Evaluation of the calcaneocuboid joint and any widening that has occurred due to the fracture is also easily accomplished with CT. CT should be interpreted in conjunction with the conventional radiographs as rotational components and flattening of the Böhler angle may be appreciated better on them than on CT.
