ABSTRACT
<p><b>OBJECTIVE</b>To study the results of using coralline hydroxyapatite (CHA) in cervical posterior laminoplasty operation.</p><p><b>METHODS</b>Two hundred and fifty-six patients underwent cervical spinous process-splitting laminoplasty using CHA. All patients had been followed up over 3 months. One hundred and forty-two patients were followed up at least 2 years. All patients had spinal stenosis at least at 3 levels or OPLL. The average follow up time was 34.6 months.</p><p><b>RESULTS</b>The CHA grafts were stable between the split spinous processes. The union rate of CHA was 83.5%. After operation, the spinal cord moved dorsally, and the anteroposterior compression ratio had been improved from 0.19 to 0.42. No apparent kyphosis occurred. The JOA score improvement rate was 58.3%. There were 24 patients (17%) with axial symptom.</p><p><b>CONCLUSION</b>Cervical posterior laminoplasty operation using coralline hydroxyapatite may achieve good results.</p>
