When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage previously placed and re-do interbody fusion with lower risks compared to revision surgery via previous passage. However, there is still some difficulty in retrieving the interbody cage from the intervertebral space because of no spacious passage, subsidence, and uncontrolled movable cage. In this study, we introduce our experience that we removed failed interbody cage more easily with only the simple additional steps of making a taphole and fixing the cage using a thread-tipped stick.
当需要进行与取出失败的椎间融合器相关的翻修手术时，通过先前的通道进行手术会导致更高的神经功能缺损或意外硬脊膜损伤风险。最近，外侧入路已成为一种流行的方法，取代了传统的前路或后路入路。与通过先前通道进行翻修手术相比，外侧入路也是取出先前放置的失败椎间融合器并重新进行椎间融合的有用方法，且风险较低。然而，由于通道不宽敞、下沉以及椎间融合器可移动且不受控制，从椎间隙取出椎间融合器仍存在一些困难。在本研究中，我们介绍了我们的经验，即仅通过制作一个攻丝孔并使用带螺纹的棒固定椎间融合器这些简单的附加步骤，就能更轻松地取出失败的椎间融合器。
