Abstract
n this issue of WORLD NEUROSURGERY, Takeuchi et al. assessed fusion rates of Plasmapore-covered titanium I cervical cages compared with noncoated titanium cages in patients who received anterior cervical discectomy and fusion (ACDF). Their study was a retrospective cohort study by design and included 30 patients in the Plasmapore-coated titanium cage (PPC) group and 42 patients in the non-Plasmapore-coated titanium cage (N-PPC) group who were followed for at least 24 months. Patients underwent standard 1-level ACDF with no additional cervical instrumentation. All cages were unpacked. Patients were followed at 3, 6, 12, and 24 months by 2 independent observers using flexion and extension radiographs and thin-cut computed tomography scan. Criteria of evaluation were radiologic stabilization and solid bony fusion. There were no surgical or perioperative complications.
