Soft tissue necrosis following using calcium phosphate cement in calcaneal bone cyst: case report

Calcium phosphate cements have received widespread attention for their possible role as bone-grafting material and bone fillers in skeletal defects. They were evaluated as a biomaterial in many aspects. No serious harmful effects such as foreign body reaction and tissue necrosis against to calcium phosphate cements have been reported yet. They were accepted as highly biocompatible materials. In this paper, we represent a patient who had soft tissue necrosis around lateral malleolar region, following using percutaneous calcium phosphate cement as a filler bone substitute in calcaneus bone cyst. The possible mechanisms were discussed.
