摘要
目的观察同种异体冻干骨加钛笼结合动力型颈前路钢板在颈椎前路减压融合术后的融合情况.方法对122例颈椎病病人行颈前路减压、钛笼加同种异体冻干骨植骨结合动力型颈前路钢板内固定术.于术前、术后6个月进行日本骨科疗效(JOA)评分,观察神经功能恢复情况;术后6个月、1年观察钛笼植骨融合率及早期沉降率.结果术后对116例随访12~22个月,平均17个月.症状均明显缓解,脊髓功能明显改善;JOA评分由术前的8.6分改善至14.1分.根据Zdeblick标准,术后6、12个月钛笼植骨融合率分别达到92.0%和95.6%,而沉降出现率分别为16.0%和18.6%.无钢板和螺钉松动或断裂现象存在.结论同种异体冻干骨加钛笼作为颈椎前路减压融合手术中的支撑性植骨材料,融合率满意,沉降率低.
Objective To observe the fusion rate of titanium mesh (Ti-mesh) with allogeneic freeze-dried bone (FDB) after anterior cervical decompression (ACD) and fusion (ACDF). Methods 122 cervical spondylosis patients were treated by implantation of FDB with Ti-mesh and internal fixation with dynamic plate after ACD. Clinical status of preoperation and 6 months postoperation were scored respectively by Japanese Orthopaedic Association (JOA) system to evaluate the recovery of nerve function. Fusion rate and early subsidence were observed at 6 and 12 months postoperation respectively. Results 116 patients were followed-up for 12 to 22 months with an average of 17 months. In 6 months postoperative follow-up, JOA score increased from preoperative 8.6 score (ranged from 6 to 12) to postoperative 14.1 (ranged from 12 to 17). According to Zdeblick standard, fusion rate of Ti-mesh with FDB and subsidence rate of the mesh were 92.0% and 16% respectively 6 months postoperation, which were 95.6 % and 18.6 % respectively 12 months postoperation. No looseness or breaking of plate and screw were observed. Conclusion Ti-mesh combined with FDB as an implant for ACDF can achieve high fusion rate and low subsidence rate.
