P109. Anterior Cervical Fusion With PEEK Cages: Clinical Results of a Prospective, Comparative, Multicenter and Randomized Study Comparing Iliac Graft and a Macroporous Biphasic Calcium Phosphate

Abstract

BACKGROUND CONTEXT: Peek cervical radiolucent fusion cages provide an immediate mechanical support after anterior cervical discectomy. The addition of iliac autograft allows a great rate of fusion but is associated with increased morbidity and persistent pain at the donor site. Macroporous biphasic calcium phosphate (MBCP) is well known for its safety, absence of allergenicity, osteoconduction properties, and has been widely used as bone substitute. Nevertheless, no clinical reports comparing prospectively the two techniques have brought evidence of the clinical advantage of MBCP use and therefore avoidance of graft harvesting.
