摘要
目的:探讨脊柱数字化重建与快速成型在复杂脊柱侧凸畸形矫治的意义。方法:采集6例复杂脊柱侧后凸畸形患者CT断层扫描数据,利用计算机进行脊柱病变区域的数字化三维重建和快速成型,并将其应用于临床。结果:术中所见与术前数字化三维重建显示和测量结果完全一致。6例患者脊柱均采用快速成型技术制作脊柱畸形模型,模型与脊柱畸形的外形尺寸完全一致,6例患者按计划完成手术过程顺利,矫形和内固定满意,未出现神经、血管损伤等并发症。术后X线和CT复查显示矫形效果满意,侧凸矫正率40.7%,后凸矫正率45.6%,椎弓根螺钉位置正确。结论:脊柱数字化重建与快速成型能够精确和直观地反映脊柱畸形情况,从而指导制定手术计划和手术操作。
Objective:To investigate the valuation of digital spine and rapid prototype in the management of complicated spinal kyphoscliosis deformity.Method:The complicated spinal kyphoscliosis CT scanned data set of 6 patients were collected,by which three dimensional reconstruction and rapid prototype were achieved for clinical treatment.Result:The observed abnormalities in the operation process were the same as the preoperative display and measurement by digital spinal three dimensional reconstruction.Spinal deformity models of 6 patients were fabricated by rapid prototype technique,which were the same size as the patient's abnormalities. The 6 patients' operations were successfully fulfilled according to preoperative plan.The correction and internal fixation were satisfied without ncurologic and vascular damage.The correction results were satisfied,and the position of the pedicle screws was accurate evaluated by postoperative X-ray and CT.Conclusion:Pathological information can be observed accurately and directly by digital spine and rapid prototype,by which preoperative plan and operation can be conducted.
