Abstract
In the treatment of tibial plateau fracture, the successful incorporation of the grafted biomaterials requires the ability of materials to promote new bone formation and provide a scaffold for osteogenesis. Due to osteogenic, osteoinductive and osteoconductive properties, the autogenous bone is still frequently used in the treatment of tibial plateau fractures. Allografts materials present similar clinical and radiological results with autogenous bone, but its use is limited by infection risk, requirement of a bone bank and high costs. Calcium phosphate cements have been proved with excellent results on medium and long term in the bone augmentation for patients with tibial plateau fractures. Hydroxiapatite tricalcium phosphate ceramics are extensively used in the treatment of tibial plateau fractures due to bioactivity and the tissue/surface bonding bioabsorbable ability that allow them to support a progressive degradation associated with bone healing and regeneration. Also, they can be used as a vehicle for osteoinductive substances, to accelerate the rate of new bone formation.
