一体化钢板前路系统在颈椎前路手术中的应用

The Application of PCB in Anterior Cervical Operation

目的 对 2 9例颈椎疾病患者应用一体化颈椎前路钢板和支架系统 (Anewanteriorcervicalinstrumentalsystemcombininganintradiscalcagewithanintegratedplate ,PCB)的临床疗效进行评估。 方法 切除椎间盘后 ,显露硬膜 ,神经根减压。选择合适型号的PCB ,置入椎间隙固定。结果 2 9例病人中 ,颈椎病 1 9例 ,颈椎间盘突出症 1 0例 ,男性 2 0例 ,女性 9例 ,平均年龄 42岁 (2 9～ 61岁 ) ,随访时间为 3～ 1 6个月。 2 3例病人接受了 1个节段的固定 ,6例病人 2个节段。该技术易于掌握和应用 ,无术中并发症及螺钉脱出或固定失败。 2 5例病人的临床症状明显改善 ,4例症状轻度改善 ,系合并较严重的颈椎管狭窄所致 ,总优良率 86 2 %。结论 PCB椎间固定稳固 ,供骨和植骨部位并发症少。

Objective The clinical effect of 29 patients who suffered from cervical diseases undergoing PCB is evaluated.Methods Among these patients, 19 were cervical spondylosis, 10 were cervical internal disc hernition, 20 were male and 9 were female, the median age was 42 years (range 29～61 years).Results They were followed prospectively from 3 to 16 months.Twenty-three patients underwent fixation at one level, 6 patients at two levels. The results show that the technique was easy to learn and implement, it has been free of intraoperative complications.After surgery no screw backout or device failure was identified.Twenty five patients improved clinically, 4 cases gently, because of serious cervical stenosis, the general excellent rate was 86.2%.Conclusion The intervertebral fixation of PCB is well,donor and acceptor site morbidity was trivial. No collars were applied after surgery.
