颈椎前路一体化钢板融合器的临床应用

目的 评价颈椎前路一体化钢板融合器治疗颈椎间盘突出症的长期疗效. 方法 对54例症状性退行性颈椎间盘突出症和急性颈椎间盘突出症患者行前路椎间盘切除减压一体化钢板融合器置入术.术后行日本脊柱学会(JOA)评分,X线片观察融合情况.随访12～79个月,甲均53.2个月.结果 所有患者术中无并发症发生.随访显示椎间隙高度和脊柱前凸已恢复,无器械断裂、远期不稳定或假关节形成.1例急性椎间盘突出脊髓部分损伤患者和3例症状严重脊髓型椎间盘突出患者症状改善不明显,其余患者治疗效果良好.术后JOA评分为13～17分,平均16.1分,术后改善率为86.7%,融合率100%. 结论 颈椎前路一体化钢板融合器治疗颈椎间盘突出症有其生物力学优势,是颈椎前路融合固定一项可靠的技术.

Clinical application of integrated anterior cervical plate cage benezech implant

Objective To evaluate the long term effect of the integrated anterior cervical plate cage benezech (PCB) implant in treatment of cervical intervertebral disc protrusion. Methods A total of 54 patients with retrogressive and acute cervical intervertebral disc protrusion were treated with anterior decompression and PCB devices of the proper sizes. The results were evaluated by Japanese Orthopaedic Association (JOA) and the fusion rate by X-rays. All patients were followed up for 12-79 months (mean 53.2 months). Results No complication occurred during the operation. The height of intervertebral space and the cervical curvature were regained postoperatively, with no implant breakage, cervical insta-bility or pseudoarticulation. All patients obtained satisfactory outcomes except for one patient with acute spinal cord injury and three with retrogressive cervical intervertebral disc protrusion. The JOA score was 13-17 points (mean 16. 1 points). All patients got fusion, with postoperative improvement rate of 86.7%. Conclusions The integrated anterior cervical PCB implant has the superiority over other im-plants in aspects of clinical application and biomechanics and is a reliable technique for anterior cervical vertebral fusion and stabilization.
