title: Anterior cervical discectomy and fusion with a compressive staple of C-JAWS.
abstract: OBJECTIVE
  To evaluate the clinical value of C-JAWS in anterior cervical discectomy and fusion (ACDF) surgery.
  
  
  METHODS
  Between January 2012 and December 2013, nine consecutive patients with cervical spondylopathy underwent ACDF process using a polyetheretherketone cervical spacer prefilled with bone substitute and secured by a cervical compressive staple in our department. The Neck Disability Index (NDI) score and visual analogy scale (VAS) of neck or arm pain as well as radiographic examination were adopted to assess the postoperative outcome and fusion.
  
  
  RESULTS
  Bony fusion was observed in all of the nine patients, and no serious surgery-related or implant-related complications were observed during the operation or postoperative period. The average operative time was 60.3 ± 11.6 min. The average hospital stay was 3.2 ± 0.8 days. The average skin incision length was about 3.0 ± 0.3 cm. The average of the follow-up days was 18.4 ± 4.3 months. At the last follow-up, the NDI changed from the baseline of 23.4 ± 10.3 to 7.1 ± 4.8, the VAS of neck or arm pain from 6.1 ± 1.0 and 4.6 ± 1.6 to 2.3 ± 1.7 and 2.4 ± 1.1, respectively. The patients' subjective satisfaction was excellent in 6 and good in 3.
  
  
  CONCLUSIONS
  Without screws, this low-profile designed compressive staple C-JAWS performed well in the ACDF surgeries.
