摘要
目的对珊瑚羟基磷灰石（ＣＨＡ）在颈椎手术中的应用进行前瞻性研究。方法对２１例颈椎间盘病变患者采用颈前路椎间盘切除减压ＣＨＡ植入术，１４例颈椎多节段受压或伴有颈椎管狭窄症患者，行颈后路椎板双开门成形ＣＨＡ植入术。对结果进行临床及Ｘ线评定。结果平均随访１８３个月，所有病例临床症状得到改善，无局部及全身异常反应。颈前路椎间盘切除珊瑚羟基磷灰石植入骨牢固愈合。颈椎管成形术后椎管矢状径增加，ＣＨＡ稳定椎弓后结构于手术开门部位。结论珊瑚羟基磷灰石植入在颈前路椎间盘切除术和颈后路椎板双开门成形术中具有良好应用前景。
Objective To study prospectively the application of coralline hydroxyapatite porous (CHA) replacement in cervical interbody fusion and doubledoor laminoplasty Methods 21 patients with cervical disc pathology were treated by anterior cervical discectomy with hydroxyapatite porous. 14 patients with extensive multilevel compressive lesions or cervical canal stenosis were treated with doubledoor laminoplasty. The spionous processsplitting space was filled with CHA. The outcome was assessed on clinical criteria and radiography of cervical spine. Results All cases were followed up for 18.3 months on average. The results showed that implantation of coralline hydroxyapatite porous after cervical surgery improved clinical results, and discectomy with CHA provided solid bone union with preservation of anatomical relations of cervical spine. The sagittal canal diameter increased after laminoplasty. The posterior elements were stabilized in open position with CHA. No local or systemic abnormal reaction occurred. Conclusion The cervical discectomy and doubledoor laminoplasty with coralline hydroxyapatite porous appear to be promising.
