Results from this study showed a higher rate of successful fusion without serious allograft-related adverse events among patients who underwent anterior cervical discectomy and fusion using a viable cellular bone allograft combined with a polyetheretherketone interbody spacer and additional anterior fixation for symptomatic degeneration at one level.
Researchers performed a prospective, multicenter study of 31 patients who underwent anterior cervical discectomy and fusion with a polyetheretherketone (PEEK) interbody spacer and anterior fixation. The viable cellular bone allograft (Trinity Evolution; processed by the Musculoskeletal Transplant Foundation) was placed within the interbody spacer for all patients. Radiographic fusion was assessed at 6 months and 12 months. Investigators assessed function with the Neck Disability Index and used the VAS to assess for neck and arm pain.
