PEREDA CARDOSO, Osvaldo  e  RUMBAUT REYES, Mauro. Treatment of closed diaphyseal tibial fractures with internal osteosynthesis and HAP-200 Coraline hydroxyapatite implants. Rev Cubana Ortop Traumatol [online]. 2006, vol.20, n.1, pp. 0-0. ISSN 1561-3100.

The tibial fractures present a high incidence of complications, such as pseudoarthrosis and consolidation retardation. An experimental comparative study was conducted from 1998 to 2003. It was selected a sample of 80 patients that presented closed diaphyseal tibial fractures that according to their characteristics presupposed a non-consolidation risk. These lesions were treated with open reduction and internal osteosynthesis by the AO method, with the particularity that half of the sample was added HAP-200 Coraline hydroxyapatite in the fracture focus aimed at stimulating osteogenesis.Satisfactory results were obtained in both groups. The group that received hydroxyapatite biomaterial stood out.The consolidation time showed better results in those patients that were applied the biomaterial. The final result of the treatment was good in 85 % and 67.5 % of the patients from the study and control groups, respectively. It was proved the usefulness of the utilization of Coraline hydroxyapatite to accelerate the osteal healing process.
