The Efficacy of Anterior Cervical Plating Systems in the Management of Degenerative Cervical Spondylosis.
Dae Yong Kim, Jong Pil Eun
Department of Neurosurgery, Presbyterian Medical Center, Jeonju, Korea.
The aim of this study is to evaluate the efficacy of anterior cervical plating systems, such as ORION? plate(locked plate), PCB plate-cage, TOP plate(unlocked plate).
This study was performed in 97 degenerative cervical spondylotic patients who adimitted to the hospital from January 1996 to March 1999. The average follow-up period was 13 months.
One-level anterior plating appeared to have better surgical results(p<0.05) and a lower complication rate(p<0.001) than multi-level plating. And a group of patients with radiculopathy appeared to have better surgical results than that of patients with myelopathy(p<0.001). Unlocked TOP? plate system appeared to have higher metallic failure rate(p<0.001) and worse results(p<0.05) than the other plating systems. The outcome based on Odom's criterion was excellent or good in 95.8% of the patients.
The one-level anterior plating of cervical anterior fusion in degenerative cervical spondylotic patients appears to have better result and no complication than multi-level plating. Also, locked plating system appears to have better result and no metallic failure than unlocked plating system.
Key Words: Degenerative cervical spondylosis; Anterior plating system; Locked plate; Unlocked plate; Plate-cage system
