ABSTRACT

OBJECTIVE
PCB cervical instrument is a newly introduced fusion device which comprises cervical plate, cage (spacer) and screw system. It is developed to enhance fusion rate and stability, as well as to reduce complications related to hardware failure. We investigated the efficacy of clinical and radiological results of PCB instrument and Lubboc bone.
METHODS
From August, 1998 to October, 1999, authors performed 54 cases of anterior cervical interbody fusion with PCB instrument and Lubboc bone. Retrospective analysis was undertaken based on clinical and radiological findings. Clinical improvement was evaluated according to Odom's criteria. Cervical plain films and tomography were taken every 2 months to evaluate the degree of interbody fusion and disc height changes.
RESULTS
Bone fusion was observed in 36 cases(90%) over 6 months after operation, and during which time there was no significant interval change. There were 3 cases of hardware dislodgement. Disc height was increased significantly and preserved in all cases. Clinical outcome over good degree was seen more than 94% of patients.
CONCLUSION
Longer follow-up period and comparative studies to similar instrument appear to be necessary, but this instrumentation system has shown high fusion rate and fewer adverse effects in our series. We believe this system might be indicated for the treatment of cervical trauma and degenerative disease in selective cases.
