Application of coralline hydroxyapatite porous replacement in cervical surgery

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.
