摘　　要：椎弓根螺钉技术因其具有良好的固定强度,目前广泛运用于脊柱外科手术中。术后螺钉的松动、拔出是其常见并发症,尤其是在骨质疏松患者中发病率更高。对此,Santoni等提出了皮质骨轨迹螺钉技术,相较传统椎弓根螺钉具有抗拔出力大、创伤小等特点。由于其特殊的置钉轨迹(自内而外、由下而上)可降低血管、神经损伤的概率,置钉安全性更高。因此,皮质骨轨迹螺钉技术可以为脊柱外科手术提供一种新的治疗方法。In current clinical practice, the pedicle screw is widely used in various spinal surgeries because of good fixation strength. However, loss of constructive stability of this fixation due to screw loosening and pull-out is well-known postoperative complications, particularly in osteoporotic patients. Recently, a new inserting technique of lumbar pedicle screw named the cortical bone trajectory(CBT) was proposed by Santoni et al, which take greater pull-out strength and less dissection than the traditional trajectory. Because of specific trajectory that the screw is inserted caudocephalic direction sagittally and mediolateral direction transversely, the CBT is facilitated to reduce risk of neurovascular damage and increase safety. The cortical bone trajectory technique can provide a novel method for spinal surgery.
