ABSTRACT

Objective. To analize the worth of using porouse hydroxyapatite (Coralin) as a bone substitute on skeletal sistic lesions on children, having an alternative on treatment. Material and methods. Fourteen pediatric patients with bone cystic lesions were operated, with curetage and application of coralin to fila up the cavity, on the 1995 to 2001 period, with a clinical and radiological follow up. Results. 85.7% of the patients were male, and 14% female. The rank of age were 4 years-9 months old to 12 years-11 months old. The follow bones were affected: humerus (50%), femur (28.5%), radius (7.1%), calcaneus (7.1%), and acetabulum (7.1%). More affected on the right side (64.2%) than the left (35.7%). We found four pathologies: simple bone cyst (57%), aneurysmatic bone cyst (28.5%), fibrous cystic displasia (21.4%), and non ossificant bone fibroma (14.2%). Complete integration of coralin were observed on 10 patients (71.4%), and partial on 4 (28.5%). There was no rejection of the material, neither an infection. Coralin has a great value as a bone graft substitute on skeletal cystic lesions in children, because of its architectural similarity and compatibility with human bone, any amount needed available, and harmless application.
