In the clinical cause of lumbar pain and lower extremity pain, numbness and other lower extremity nerve symptoms, more common diseases are lumbar spine slippage and lumbar disc herniation, these two diseases are not the same, mainly the pathological state and treatment methods are different, as follows: 1, the pathological state: lumbar spine slippage refers to the lumbar spine adjacent to the two vertebrae occurred relative slip, the beginning symptoms are generally light, with the aggravation of slippage can appear persistent The symptoms are often relieved when resting in bed, and are significantly aggravated after standing and walking. The severity of the slippage can be clarified through the frontal and lateral radiographs of the lumbar spine as well as the power radiographs of the hyperextension and hyperflexion position. The most clear examination means for the diagnosis of lumbar disc herniation is lumbar MRI. 2, Treatment: Lumbar slippage is mainly treated by the repositioning and fixation of the slipped vertebrae, which generally requires the placement of built-in objects, that is, pedicle screws. The lumbar disc herniation can be treated more or less by relatively simple minimally invasive surgery to remove the herniated nucleus pulposus and reduce the compression on the nerve. The specific choice of treatment will depend on the patient’s imaging data, severity and physical condition after a comprehensive assessment to further develop the treatment plan.
