Abstract:
[Objective]To study the application of allogenic bone spacer in double-door expansive laminoplasty.[Method]From Apr.2003 to Jun.2004,22 patients underwent double-door expansive laminoplasty using allogenic bone spacers in authors department.All patients were followed up for 16～30 months,with an average time of 18.4 months.JOA scoring system was used to evaluate the neurological status.ROM of cervical spine and bone fusion was determined on X-ray and CT at follow-ups.[Result]At final follow-up,JOA scores improved from(8.3?2.6)points before surgery to(13.3?3.1)points.ROM of cervical spine was reduced from(41.3?10.8)? to(23.4?8.7)?.No postoperative instability happened after operation.Bone fusion between allograft and spinous processes was completed in 69.6%,partial in 23.2% and failed in 7.1% of the operated levels.No breakage and displacement of allograft spacers were found.[Conclusion]Double-door expansive laminoplasty using allogenic bone spacers is safe and effective for cervical spondylotic myelopathy.
