rhBMP-2 in Cervical Arthrodesis

Completed

Conditions studied: Cervical Arthrodesis

In brief

This prospective study will investigate the use of recombinant human bone morphogenetic protein (rhBMP-2) in the current surgical standard of care for cervical spine pathology. Specifically, the outcomes of three forms of cervical fusion will be investigated: 1. Anterior cervical fusion with rhBMP-2, allograft corticocancellous bone as an interbody device, and anterior cervical plate fixation. 2. Posterior cervical fusion with rhBMP-2, local bone graft, with or without posterior screw fixation. 3. A combination of the previous two approaches: a combined anterior-posterior cervical fusion with rhBMP-2.
