Bilateral Calcaneal Fractures in Children Treated with a Minimally Invasive “Sinus Tarsi” Approach and Bone Grafting: A Two-Case Report

Background Bilateral intra-articular calcaneal fractures are extremely rare in children. Surgical management is challenging, and maintaining articular congruity can be difficult. Case Presentation We report two pediatric cases of bilateral displaced intra-articular calcaneal fractures treated via a minimally invasive sinus tarsi approach combined with cancellous bone grafting, without internal fixation. The bone graft was used to support the articular surface and restore calcaneal height and morphology. Anatomical reduction of the subtalar joint and restoration of calcaneal morphology were achieved in both patients. Bone grafting provided stable subchondral support, and no wound-related complications occurred. At follow-up, both children demonstrated good functional recovery and returned to normal activities. Conclusion The combination of the sinus tarsi approach with cancellous bone grafting alone appears to be a safe and effective option for pediatric displaced intra-articular calcaneal fractures, providing stable reduction, subchondral support, and minimal soft-tissue morbidity.
