摘要
目的评价颈椎前路一体化钢板椎间融合器(PCB)的优越性。方法颈椎前路椎间盘摘除术后,选用适当型号的一体化钢板椎间融合器(PCB)置入,无需透视帮助即可拧入螺钉和植骨。治疗脊髓型颈椎病26例,颈椎外伤伴有急性椎间盘突出症30例,颈椎骨折脱位(无关节交锁)失稳12例,本组随访4～36个月,平均17个月。结果颈椎间融合率为93.4%,椎间隙高度平均增高31.3%;脊髓型颈椎病术前JOA评分7-12分,平均为9.7分,术后评分为12～17分,15.9分,术后改善率为84.9%。外伤后颈椎间盘突出症和颈椎骨折脱位失稳患者术后恢复情况为(按Frankle分级):2例A级恢复至B级、1例A级恢复至C级、7例B级恢复至C级、2例B级恢复至D级、16例C级恢复至D级、2例C级恢复至E级、10例D级恢复E级,有2例A级手术前后未有恢复。49例患者接受单节段固定,16例患者为双节段固定,3例患者为三节段固定。结论在颈椎病、颈椎间盘突出症和颈椎骨折脱位失稳的治疗中PCB系统显示了在生物力学和临床上的优点,PCB为颈椎前路内固定术提供了一个可靠的系统。
Objective To evaluate the superiority of the integrated anterior cervical plate cage benezech（PCB） implant. Methods After a standard anterior cervical disectomy and preparation of the disc space, the correct size of PCB implant was inserted. Self-tapping screws were inserted without any intensifier. Cancellous bone chips were used. The technique was used in 68 cases that were followed up for 4-36 months（average 17 months）, of which there 30 with cervical trauma complicated by acute intervertebral disc protrusion and 26 with cervical spondylitic myelopathy, and 12 patients who suffered from fracture dislocation instability of cervical spine without locked joint. Results 26 cases with cervical spondylitic had the preoperative score of Japanese Orthopaedic Association（JOA） for 7-12 points （average 9.7 points） and the postoperative one for 12-17 points（average 15.9 points）, with mean recovery rate of 84.9%. 42 cases were differently made recovery according to Frankle classes, with cervical trauma complicated by acute intervertebral disc protrusion or with being suffered from fracture dislocation instability of cervical spine, of which there two cases were made recovery from A to B, one form A to C, seven from B to C, two form B to D, sixteen from C to D, two from C to E, ten from D to E, and two cases in class A had no change. Fourty-nine cases underwent fixation by one segment, sixteen by two segments and three by three segments. No intraoperative complications occurred except for one screw that was loose and backed out In the meantime, no complications were found in the donor site. Conclusions The PCB implate can prevent from complicationsoccurring in bone graft recipient and donor site, provide immediate biomechanical stability, prevent screw backout or breakage, restore intervertebral height and lordosis and is free from collars post operation.
