Calcaneal Fractures in Children An Evaluation of the Nature of the Injury in 56 Children

Abstract

The traditional view of calcaneal fractures in children is that this injury and its consequences are generally less severe than its adult counterpart. The validity of this conception and other ways in which children's fractures differ were examined by a retrospective review of children's injuries. The fracture patterns encountered in children 15 years of age or older resembled those of adults. Intra-articular Type 5 fractures were predominant. Children 14 years of age or younger had predominantly extra-articular fracture patterns, a possible reflection of less frequent mechanisms of vertical compression loading in children and their ability to absorb compression loading. Extra-articular and intra-articular Type 4 fractures were characteristically nondisplaced injuries, with normal calcaneal articulations being preserved in all cases. Unrecognized calcaneal fractures were frequent, reflecting both the difficulty of detecting minimal osseous injury and the benign nature of the unrecognized fracture. Associated fractures of the extremities, twice as frequent in children as adults, and axial skeletal injuries, half as frequent as in adults, should not be overlooked. The prognosis for a normally functioning calcaneus without the presence of post-traumatic arthrosis should be expected in most cases due to the nature of the fracture in children.
