Pediatric Calcaneal Fractures

Abstract

Calcaneal fractures in pediatric patients are seen infrequently. We retrospectively reviewed 22 skeletally immature patients with 23 fractures of the calcaneus before their distal tibial physis had fused. Eighteen (78%) of these fractures were intraarticular and five (22%) were extraarticular. Nine patients were followed for an average of 4.4 years. Of these nine fractures, 8 were treated nonoperatively and one was treated with open reduction and internal fixation. A modification of the American Orthopaedic Foot and Ankle Society scoring system, which focuses on residual complaints of pain, work or sports restrictions, ability to walk on different surfaces and gait abnormalities, was employed to assess their outcome. Seven of the nine patients were free of pain, had unrestricted foot function, and possessed no apparent gait abnormalities. Two patients had activity related and cold weather related pain. We believe that the excellent prognosis for both intraarticular and extraarticular fractures, seen in this study is multi-fold. First, the immature talus and calcaneus have a superior capacity to remodel. Second, pediatric calcaneal fractures are usually consequence of low energy trauma. Lastly, a favorable intraarticular fracture pattern, unique to the skeletally immature calcaneus may exist, rendering a good prognosis.
