Use of Coralline Hydroxyapatite and Autologous Growth Factors in Pediatric Patients Undergoing Posterior Spinal Fusion for Correction of Scoliosis

• (a-Interpore-Cross International)

The accepted surgical management of scoliosis relies on correction of the deformity with resultant stable fusion. Autogenous bone grafting is the gold standard for spine fusion, however, not without complications. Alternative graft choices have been widely studied, but with variable outcomes.

At our institution, we examined 21 pediatric patients who underwent posterior spinal fusion and instrumentation supplemented with coralline hydroxyapatite and autolgous growth factors. The patients did not receive supplemental autogenous or allograft bone graft.

All patients had a minimum 24 months clinical and radiographic followup. Radiographs were graded as definitely a fusion, definitely a pseduarthrosis, or unable to grade. All patients went on to stable spinal fusion. No patient required additional bone grafting or instrumentation.

We believe that coralline hydroxyapatite and autologous growth factors are safe and effective alternatives to autogenous or allograft bone when attempting to achieve a stable fusion in patients undergoing deformity correction.
