Abstract:
[Objective]To verify whether or not the modified open-door laminoplasy preserving semispinalis cervicis insert into axis is effective in preventing postoperative axial symptom and maintaining postoperative cervical sagittal alignment.[Method]Since March 2002 to December 2003,forty-eight patients underwent modified open-door laminoplasy preserving semispinalis cervicis insert into Axis,among them,thirty-two patients who were followed up for more than 2 years were included in this study.Preoperative and postoperative JOA score,degree of axial symptom,ranges of neck motion,cervical curvature index were recorded and compared.[Result]Preoperative and postoperative JOA score was(9.04?2.9)and(12.5?3.1)respectively,with recovery rate as(44.9?26.9).There was significant difference between preoperative evident axil symptom rate(46.8%)and postoperative evident axil symptom rate(18.7%),while no significant difference between preoperative and postoperative ranges of neck motion,cervical curvature index was seen.[Conclusion]Modified open-door laminoplasy is less invasive to the posterior extensor mechanism especially the semispinalis cervicis than conventional open-door laminoplasy.This new procedure is effective in preventing postoperative morbidities often seen after conventional laminoplasy with adequate decompression of the spinal cord.
