The aim of the experimental part was to retrospectively asses the use of Atlantik® BCP (a mixture of 70% Hydroxyapatite and 30% beta-tricalcium phosphate) combined with plate osteosynthesis for management of 27 collapse tibial plateau fractures. All fractures healed after a mean time 2.8 months, while the mean time for disappearance the radiolucent zones between the implanted ceramic and receiving tissue was 15 weeks. We noticed a Neer score of 85 points with no reaction to bone substitute or evidence of biomaterial degradation. The study demonstrated that biphasic ceramic biomaterial Atlantik®, combined with supportive plate osteosynthesis, is an effective synthetic bone substitute due to a fast healing and good quality osseointegration.
