单侧经皮穿刺脊柱后凸椎体成形术的入路探讨 |

3 cm,1.4±0.4 cm preoperatively and2.2±0.4 cm、2.3±0.3 cm postoperatively;the Cobb angle was decreased from 28.4±10.2° preoperatively to 19.2±4.5° postoperatively.The mean absolute value of the difference in height between right and left side of the vertebral bodies was 0.1 cm in this group.Conclusion The kyphosis is improved and the operative time is reduced by unilateral kyphoplasty obviously.Though this result is satisfied,more clinical studies are needed to be done for authenticating the efficacy of unilateral kyphoplasty on the treatment of vertebral compression fractures in the future.

经皮脊柱后凸成形术(percutaneous kyphoplasty,PKP)由经皮椎体成形术(percutaneous vertebroplasty,PVP)发展而来,主要手术过程是经双侧椎弓根穿刺,建立工作通道,置入2枚特制球囊(inflatable balloon tamp,IBT),加压扩张后在低压下填入骨水泥,所以有人[1]又把PKP称作球囊辅助的PVP(balloonassisted vertebroplasty)。此外,PKP还可以用来复位压缩的椎体,纠正脊柱后凸畸形。PKP治疗椎体压缩骨折的临床疗效已得到公认,但双侧穿刺手术时医生和患者暴露在射线下的时间较长,造成的放射损害是阻碍PKP在更大范围内应用的瓶颈。我们对手术穿刺方法进行改进,采用单侧穿刺方法施行PKP,显著减少了对射线的接触,在临床实践中取得了一些手术操作经验,报道如下。
1 材料和方法
1.1 体外解剖学研究资料 取L1椎体,于上关节突外缘和横突上缘交界稍外上处穿刺,进针角度与椎骨矢状面呈30°~45°,顺椎弓根进入椎体,测量显示穿刺针尖的位置,以便球囊放置到理想位置。
1.2 临床资料 本组病例共36 例,45节手术椎体,男性9 例,女性27 例;年龄63~88 岁,平均74.8 岁。发生疼痛等症状至手术的时间为7 d~10个月,平均5.6个月。手术病例除5 例是肿瘤性椎体病理骨折外,余为骨质疏松性椎体压缩骨折(osteoporoti上一页 [1] [2] [3] [4] [5] [6] 下一页 上一个医学论文: 自体髂骨移植联合BMP治疗四肢长骨干骨折不愈合 下一个医学论文: 肱骨远端复杂粉碎性骨折的手术治疗
