A hydroxyapatite-based synthetic bone graft reduces intervertebral motion at 12 months, as measured by CT-RSA, in a porcine model of ACDF
Introduction Pseudarthrosis remains a significant complication after anterior cervical discectomy and fusion (ACDF), often causing revision surgery. Synthetic bone grafts (SBGs) offer an alternative to autografts, but objective methods for assessing intervertebral motion (IVM) are needed. Computed tomography-based radi...
