A 55-year-old female sustains a Schatzker Type II lateral tibial plateau fracture with 8mm articular depression after a fall. You plan ORIF with plate fixation and need to fill the metaphyseal void created when the depressed articular fragment is elevated. The patient asks about bone graft options. You discuss calcium phosphate cement as a synthetic bone void filler that can provide structural support and be replaced by bone over time, without the morbidity of autograft harvest.
