摘要:

背景:椎体成形与椎体后凸成形经皮穿刺成败的关键是穿刺针能否准确地经椎弓根到达椎体,因此在X射线透视下经皮确定穿刺针正确的进针点及方向极为重要。目前文献报道的许多穿刺方法中穿刺点及穿刺角度不固定,对穿刺针是否穿破椎弓根内侧壁这一并发症报道较少。
目的:从解剖学和影像学角度寻找安全、有效的经皮椎弓根定位穿刺点及穿刺角度。    
方法:寻找行经皮椎体成形时X射线透视下的最佳进针点:在胸、腰椎骨格标本(T6-L5)上进行解剖研究寻找椎弓根中轴线通往椎体后方的解剖位置,该位置就是行经皮椎体成形穿刺针的最佳进针点,用微型螺钉固定予以X射线透视,分析最佳进针点在X射线透视下与椎弓根显影的位置关系,从而寻找X射线透视下的最佳进针点。寻找行经皮椎体成形时的最佳进针角度:对成人胸、腰椎骨格标本(T6-L5)用尸体解剖和CT扫描两种方法测得椎弓根中轴线和椎体矢状线夹角的平均值。寻找经皮椎体成形时的最佳进针角度。
结果与结论:行经皮椎体成形时X射线透视下的最佳进针点为左侧椎弓根投影9点区域及右侧椎弓根投影3点区域。行经皮椎体成形时的最佳进针角度:腰椎L1-L4为5°-10°;L5一般为20°,最多不超过25°;胸椎T6-T12为5°左右。

Abstract:

BACKGROUND: The key of vertebroplasty and percutaneous kyphoplasty to success is whether the puncture needle can accurately reach the vertebral body through pedicle. Therefore, it is important to identify the correct point and direction of needling in the X-ray fluoroscopy. Among many methods published in present reports, the puncture point and the puncture angle are not fixed. Few reports concerned whether the puncture needle perforated pedicle medial wall.
OBJECTIVE: To seek safe, effective puncture point and the puncture angle of percutaneous pedicle from the perspective of anatomy and radiography.
METHODS: The best entry point during percutaneous vertebroplasty in the X-ray fluoroscopy: dissection was performed on thoracic, lumbar skeletal samples (T6-L5) to find the position of pedicle axis leading to the rear of the vertebral body, and this position is the best entry point of percutaneous vertebroplasty. It was fixed with mini-screw. The relationship of the best entry point and pedicle developing position in the X-ray fluoroscopy was analyzed to find the best entry point in the X-ray fluoroscopy. The best entry angle during percutaneous vertebroplasty: The average included angle of pedicle axis and vertebral sagittal line was measured using autopsy and CT scanning on adult thoracic and lumbar skeletal samples (T6-L5). The best entry angle during percutaneous vertebroplasty was found.
RESULTS AND CONCLUSION: During percutaneous vertebroplasty, the best entry point in the X-ray fluoroscopy was the left pedicle projection 9 area and right pedicle projection 3 area. The optimal needle angle during percutaneous vertebroplasty: 5°-10° in lumbar vertebra L1-L4; 20° in L5, not more than 25°; about 5° in thoracic vertebra T6-T12.
