一体化钢板前路系统治疗颈椎骨折、脱位及失稳

目的：对16例颈椎骨折脱位及失稳患者应用一体化左面椎前路钢板和支架系统（PCB）的临床疗效进行评估。方法：切除椎间盘，使骨折复侠后，再行一体化钢板固定。结果：11例病人接受1个节段的固定，5例双节段固定。无术中并发症及镙钉脱出或固定失败。14例病人神经功能有不同程度改善，2例无效，总优良率81．25％。结论：PCB椎间固定稳固，有助于恢复和保持颈椎生理曲率，供骨和植骨部位并发症少。术后不需戴颈托。

Treatment of fracture-dislocation-instability of cervical spine by PCB

Objective To evaluate the clinical effects of PCB on 16 patients who suffered from fracture dislocation instability of cervical spine.?Methods After resecting internal disc to replace the fracture,the internal fixation by PCB was made.?Results Among these patiens,10 cases were male and 6 were female.Their disease couse were 8 hours to 11 months.They were followed prospectively from 3 to 16 months.Eleven patients underwent fixation at one level,and 5 patients at two levels.All of them have been free of intraoperative complications. After surgery,no screw backout or device failure was found. The nerve function of 14 patients were improved clinically with 2 of whom had no change.The general excellent rate was 81.25%.?Conclusion The intervertebral fixation of PCB is reasonable,and it can help cervical vertebrae resume and keep physiological curve with no donor and acceptor site morbidity.No collars was needed after surgery.
