RADIOGRAPHIC EVALUATION OF THE USE OF XENOGENEIC GRAFT IN THE TREATMENT OF SCOLIOSIS

ABSTRACT Objective: To evaluate the radiographic results obtained using a bone substitute of xenogeneic origin as an adjunct to consolidation in a sample of patients diagnosed with scoliosis and undergoing surgical treatment in a tertiary hospital. Methods: The total sample consisted of 12 female patients, with an average age of 13.5 years. There was a predominance of the single posterior approach (83.3%) In all cases, 30g of the xenogeneic graft was used. Results: The average Cobb angle of the main curve was 85.5 degrees and of the minor curve was 49.2 degrees. We obtained a mean main curve correction of 48 degrees or 56%, which remained in the measurements 6 months postoperatively. The analysis of arthrodesis consolidation demonstrated a predominance of cases classified as Molinari Grade 2, n= 7, (58.7%) at 3 months and at 6 months, n= 8, (66.7%), associated with three Molinari cases Grade 1 (25%) noting a total of 91.7% consolidation of the arthrodesis. Conclusion: The use of the xenogenic graft of bovine origin Bonefill Mix from the company BionnovationR demonstrated a good consolidation rate, being a consolidation adjuvant that can be used to treat these patients.
