ABSTRACT

Objective. To show that the ceramic produced at the Institute for Materials Research, National Autonomous University of Mexico, is an appropriate replacement of bone graft in patients with bone tumors, benign tumors, pseudoarthrosis and arthrodesis treated at «General Ignacio Zaragoza» Regional Hospital. Material and methods. An experimental, longitudinal study using bovine ceramic xenoimplants in patients covered by the Security and Social Services Institute for Civil Servants (ISSSTE), regardless of age and gender, all of whom consented to receiving the ceramic xenoimplant. Patients who did not consent or who discontinued treatment were excluded. A total of 24 patients were enrolled from March 1st to August 31st, 2006; two patients were withdrawn due to treatment discontinuation. They underwent X-ray evaluation of bone healing using the Montoya classification. Results. The sample is composed of 14 male and 8 female patients, with a mean age of 46.6 years, and a standard deviation (s=) of 13.8. The most frequent indication was arthrodesis in 10 patients (45.45%), pseudoarthrosis in 6 (27.27%), benign tumors in 3 (13.63%), and bone defects in 3 (13.63%). Type II to type IV bone healing was observed in the sample. Discussion. The use of ceramic xenoimplants is appropriate as a replacement of bone graft in patients with arthrodesis and bone defects, thus avoiding the need for autologous bone graft. This results in a decreased patient morbidity.
