OBJETIVE: To present the results of the use of biological ceramic in filling bone defects resulting from traumatic or orthopedic injuries. METHODS: We evaluated 36 patients with bone defects caused by trauma or orthopedic injury. Nineteen patients were male (52.8%) and 17 were female (47.2%). Age ranged from 19 to 84 years, with a mean of 45.7 years and median of 37 years. We only included patients with defects which required at least five grams of biological ceramic. Eighteen cases were classified as orthopedic; bone defects were observed in 11 of the total hip arthroplasties; one case of primary total hip arthroplasty, by coxarthrosis; femoral or tibial open wedge osteotomies, five cases; and tarsal arthrodesis, one case. There were 18 cases of trauma-related defects; uninfected pseudarthrosis, 8 cases; recent fractures of the tibial plateau with compression of the spongious bone, 3 cases; and fractures treated with external fixators, 7 cases. The surgical technique consisted of curetting and debriding the injury until viable bone for grafting was found. Biological ceramic was used to fill the gap and some kind of fixation was applied. RESULTS: Of the 36 patients evaluated, we observed that 35 (97.2%) showed integration of biological ceramic, 1 case of open fracture treated with external fixation had poor integration of biological ceramic. CONCLUSION: Treatment of bone defects of orthopedic or traumatic etiology with the use of a phospho-calcium ceramic composed of hydroxyapatite, has been proven as practical, effective and safe.
