Lumbar spine slippage surgery with broken internal fixation that cannot be removed requires open surgery to remove the broken internal fixation. Patients with lumbar spondylolisthesis are first decompressed surgically and then fixed and fused. However, the slipped vertebrae are inherently unstable and are themselves subjected to greater shear stresses, so lumbar spondylolisthesis surgeries are more prone to loosening and breaking than other lumbar spine surgeries. Once the internal fixation loosens or breaks, the outcome of the surgery can be greatly affected. A broken internal fixation can be removed through minimally invasive surgery, and the unbroken part does not need to be removed. If the broken internal fixation cannot be removed, open surgery is needed to expose the broken internal fixation to the field of view and remove it, and it can be fixed again if the slippage has not been corrected. If the slip is not corrected, it can be re-fixed. It is recommended that the broken internal fixation of lumbar spondylolisthesis surgery can not be removed under the guidance of the doctor to choose the appropriate method of removal.
