The application of Zero-profile implant in two-level and single level anterior cervical discectomy and fusion for the treatment of cervical spondylosis: a comparative study

چکیده
While the application of the Zero-P implant (Zero-P, Synthes GmbH, Switzerland) in two-level ACDF has been little reported, a retrospective study was conducted to compare the clinical outcomes with radiographic data and complications between two-level and single level ACDF using Zero-P. A total of 132 patients who underwent ACDF using Zero-P between September 2011 and December 2014 in our department were retrospectively reviewed. The Japanese Orthopedic Association (JOA) scale score, neck disability index (NDI), neck and arm visual analog scale (VAS), bony fusion rate and main complications were recorded. Dysphagia was evaluated according to the Bazaz grading system. The results are based on 74 patients in the single level group and 41 patients in the two-level group. There were no significant difference between two groups concerning age, gender, smoking, alcohol, diabetes mellitus, VAS for neck, VAS for arm, NDI and JOA scores before surgery (all, P>0.05). The JOA, NDI and VAS pain scores in two groups were significantly improved after surgery (all, P<0.05). Similar improvements were observed in the JOA, NDI and VAS pain scores in both groups each follow-up (all P>0.05). There was no significant difference in two groups concerning postoperative main complications (all P>0.05). In conclusion, no significant difference was observed between two groups in terms of clinical improvement, fusion rates and main complications. The Zero-P implant may be an effective and safe choice in two-level ACDF surgery. Future prospective, randomized, controlled studies with larger sample size are needed.

Comparison of anterior cervical discectomy and fusion with the zero-profile implant and cage-plate implant in treating two-level degenerative cervical spondylosis
Previous studies based on small sample sizes have reported the application of the Zero-P implant (Zero-P, Synthes GmbH, Switzerland) in single anterior cervical discectomy and fusion (ACDF) surgery with excellent outcomes. However, the safety and effectiveness of two-level ACDF with Zero-P implant still remains controversial. A retrospective study was conducted to compare the clinical outcomes ...

BACKGROUND Zero-profile implant has become more and more popular in anterior cervical discectomy and fusion (ACDF) for the treatment of degenerative cervical spondylosis. However, there was no enough evidence judging its efficiency and safety. The aim of this analysis was to evaluate the efficacy and safety of Zero-profile implant compared with conventional cage-plate (CCP) in ACDF. METHODS A...

Background: After cervical discectomy, autogenetic bone is packed into the cage to increase the rate of union between adjacent vertebral bodies, but donor site–related complications can still occur. In this study we evaluate the use of hydroxyapatite granules as a substitute for autograft for interbody fusion. Methods: From November 2008 to November 2011, 236 patients participated in ...
