Abstract:
OBJECTIVETo study the results of using coralline hydroxyapatite (CHA) in cervical posterior laminoplasty operation.
METHODSTwo 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.
RESULTSThe 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.
CONCLUSIONCervical posterior laminoplasty operation using coralline hydroxyapatite may achieve good results.
