    Objective : The Orion instrument is well-known 2nd generation cervical plate system with fixed trajectory screws. To evaluate its suitability for cervical degenerative disease, the author presented a retrospective long-term analysis of clinical and radiological outcomes. Methods : Thirty-one cervical degenerative disease patients were investigated with a follow-up period of at least 2 year(mean:32Mo) after cervical fusion with the Orion locking plate. A comprehensive evaluation of clinical outcomes, the rate of bony fusion, extent of subsidence, change of cervical lordosis, operative complications including hardware-related complications was performed at preoperative, postoperative, 6months later after operation, final follow-up period. Results : The successful fusion rate was 90%(28 patients). Clinical outcomes were revealed with excellent in 11 (36%), good in 20 patients (64%). Mean height of bony fusion was increased to 2.46 ? 1.47 mm at final follow-up. Mean subsidence of bony fusion was 0.99 ? 0.96 mm finally. Mean Gore angle was corrected from 12.8 ? 7.1? to 16.7 ? 6.5 ? Pseudarthrosis was observed in three cases (10%) without radiological instability. Hardware-related complications were revealed plate fracture, screw fracture, screw loosening, accelerated adjacent disc level degeneration and postoperative foreign body sensation. Conclusion : Orion cervical plate system provided relatively effective fixation in patients with degenerative cervical disease including a 90% successful fusion rate, less than mean 1 mm subsidence, relatively minimal hardware complications. However, it would be recommended next generation plate systems in patients with cervical degenerative disease in order to increase fusion rate and to minimize hardware-related problems including fixed angle screw, thick plate.
