Introduction For decades, open reduction and internal fixation was the surgical treatment of choice for intra-articular calcaneal fractures, either with or without any augmentation. Delayed weight bearing and wound-related complications are still unresolved. Aiming at a minimally invasive therapy with accelerated mobilization, we applied closed reduction and balloon-assisted augmentation with calcium phosphate cement. Case presentation A 45-years-old Greek man with intra-articular calcaneal fracture was treated with closed reduction and balloon assisted augmentation with calcium phosphate cement. Follow-up was performed using the Maryland foot score, plain radiographs and multidirectional computerized tomography. Early full weight-bearing was performed at the end of the first week postoperatively. There was no need for secondary reconstructive procedures at the 2 year follow-up. The patient had minimal problems regarding the pain, subtalar motion and peroneal impingement. There was no significant further collapse of the subtalar calcaneal articular surface radiologically. Conclusion The closed reduction and balloon assisted augmentation with calcium phosphate cement of intra-articular calcaneal fractures is a minimally invasive surgical procedure which led to early full weight bearing, good functional patient outcomes and a low complication rate.
