Polyetheretherketone (PEEK) cage filled with bone morphogenic protein and demineralised bone matrix in anterior cervical discectomy and fusion

摘要

We read with interest the article by Liao et al. on polyetheretherketone (PEEK) cage filled with cancellous allograft in anterior cervical discectomy and fusion (ACDF) . The authors reported on the use of freeze-dried cancellous allograft bone in ACDF with 100% fusion rates and 74% good/excellent outcomes . PEEK has been used in ACDF for years with positive reports on postoperative foraminal height, fusion rates and clinical outcomes [2, 3]. We would like to offer our experience and technique with the use of PEEK and demineralised bone matrix putty combined with bone morphogenic protein (BMP) in ACDF. We have used this technique successfully in hundreds of patients and preface the use of BMP in the cervical spine with a warning.
