The use of recombinant human BMP-2 as a salvage procedure in the pediatric spine: a report on 3 cases.

Abstract

The study is a retrospective case series. The objective is to review the results after off-label recombinant human BMP-2 (rhBMP-2) use in the pediatric spine after previously failed spinal fusion. Non-union in the pediatric spine is a challenging condition associated with increased morbidity due to instability, neurological impairment or multiple revision surgeries. BMP has been used with good results in the adult spine; however, information on its use in the pediatric population is still lacking. rhBMP-2 was used at our institution at revision posterior spinal surgery in three patients. Solid spinal fusion was achieved in all three cases despite underlying bone dysplasia (Hurler's disease), instability or bony substance loss. No adverse reactions due to rhBMP-2 use were observed. rhBMP-2 should be considered as potential option to achieve spinal fusion in children with compromised bone healing due to congenital, local or systemic conditions.
