I met a patient who had been struggling with this problem for a long time; I have been “drumming” in my heart, huh, does he have to have “vertebral slippage” to be satisfied? Let’s analyze the reasons for this consequence! The occurrence of lumbar spondylolisthesis, isthmic fracture is the basis, the abnormalities of the spinal physiological curvature is the main cause of slippage. The stability of the spine depends on the integrity of the spinal bone and joint structure and the strong maintenance of the surrounding muscles and ligaments on the one hand, and on the normalization of the physiological curvature of the spine on the other. We know that the lightning rod of the building can guide lightning into the ground and play a role in turning danger into peace, and so is the principle of our spine mechanics, if the physiological curvature of the lumbar spine is within the normal range, although the isthmus collapses (bony structure is incomplete), the gravity of the body load will also be transmitted from the lumbar spine and sacral vertebrae along the pelvis to the lower extremities until the feet, thus avoiding the possible increase in the lower back section of the injurious load, otherwise This can lead to lumbar spondylolisthesis. Therefore, as long as the muscles and ligaments around the spine function well, the curvature of the lumbar spine is within the normal physiological range, and the relationship between the vertebral bones and joints is in normal mechanical equilibrium, vertebral slippage may not occur even if there is a fracture in the isthmus, which is why we emphasize restoring the physiological curvature of the spine in the treatment of spinal strain disease. Therefore, vertebral slippage does not necessarily occur when the vertebral arch isthmus is cracked, and regular exercise of the muscles around the spinal bones and joints and strengthening of the ligaments can contribute to spinal health.
