Computerized tomographic analysis of acute calcaneal fractures.

Computerized tomography (CT) of the hindfoot is introduced as an effective technique in the evaluation of acute, intra-articular calcaneal fractures. Thirty-two fractures in 30 patients have been reviewed, and common fracture characteristics identified. These included the presence of a sustentacular fragment, displacement and comminution of the lateral weightbearing surface, and lateral spread with loss of calcaneal height. Based on the improved understanding of fracture anatomy provided by the CT scan, treatment often can be determined more accurately.
