The use of porous corundum ceramics in spinal surgery

International Orthopaedics Aims and scope Submit manuscript

Summary

Between 1987 and 1991 the spine was stabilised in 205 patients using corundum ceramic implants. The radiological results were assessed with a follow up of from 6 to 24 months and were graded as good in 81%. Poor results were not due to the implanted material, but were usually caused by failure to obtain full correction of the deformity at operation. Porous ceramic implants produce better radiological results, with a decrease in operating time and a reduced risk of infection.

Résumé

Cet article présente l'analyse des résultats radiologiques obtenus chez 205 malades opérés d'Octobre 1987 à Décembre 1991 au Centre Métropolitain de Rééducation de Konstancin. Pour obtenir la stabilisation des fractures du rachis, nous avons utilisé des implants de céramique produits par l'Ecole Polytechnique de Wroclaw. L'évaluation des résultats radiologiques, de 6 mois à 2 ans après l'opération, montre que ceux-ci sont favorables dans la majorité des cas (81%). Les mauvais résultats ne sont pas dus à la qualité du matériel implanté mais le plus souvent à l'impossibilite d'obtenir une réduction chirurgicale complète de la déformation du rachis. Les auteurs concluent de leur expérience que les implants de céramique ont un intérêt clinique indiscutable. Leur utilisation permet une amélioration des résultats radiologiques, une réduction de la durée de l'intervention ainsi qu'une diminution du risque d'infection post-opératoire.
