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

AVALIAÇÃO RADIOGRÁFICA DO USO DE ENXERTO XENOGÊNICO NO TRATAMENTO DA ESCOLIOSE

EVALUACIÓN RADIOGRÁFICA DEL USO DE INJERTO XENOGÉNICO EN EL TRATAMIENTO DE LA ESCOLIOSIS

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 Bionnovation^R demonstrated a good consolidation rate, being a consolidation adjuvant that can be used to treat these patients. Level of Evidence IV; Prospective Case Series.
