3D打印技术辅助治疗颈椎棘突孤立性骨软骨瘤1例

2017-11-15 佚名 中国骨与关节损伤杂志

患者,女,12岁,以“发现颈部皮下突起12年”入院。

【一般资料】

患者,女,12岁

【主诉】

以“发现颈部皮下突起12年”入院。

【现病史】

12年前患者无明显原因及诱因出现颈部皮下突起,后于本院就诊考虑“骨软骨瘤”,建议年龄较大时手术治疗。近来患者每当俯身写字时即感颈部酸胀等不适,且症状有加重趋势。

【体格检查】

颈椎序列可,生理曲度存在,C3~5棘突区可见骨性突起,尤以C5棘突区明显,质地较硬,触之无明显活动,无明显触叩痛;胸腰椎、双上肢无畸形,无压痛,有叩击痛,生理弯曲存在,活动自如,生理反射存在,病理反射未引出。

【辅助检查】

X线片显示C5棘突形态不规则,其后可见近端膨大、远端变细的高密度阴影,椎间隙无明显狭窄,局部软组织突起。CT显示C5棘突骨软骨瘤(图1),并将患者CT扫描原始数据导入3D打印软件,然后打印出病变椎体1∶1模型(图2)。



【治疗】

完善术前准备后,在全身麻醉下手术取出一长约5CM的C5椎体棘突外侧部向下延伸出的孤立性条索状骨性突起,术后随防1年未见复发。
