Osteoporosis may lead to lumbar disc protrusion, osteoporosis leads to lumbar disc protrusion mechanism are mainly as follows: First, when osteoporosis occurs, it will involve the spine parts, and then the bone strength here is significantly reduced, in some cases, it will also cause compression fractures of the vertebrae. Once this happens, there will be obvious changes in the shape of the spine, and deformities such as stooping may occur, and the intervertebral discs between the vertebrae may be squeezed by abnormal external forces, and the intervertebral discs may rapidly degenerate and then produce such diseases. Second, in the presence of osteoporosis, the bone strength of the spinal vertebrae will be significantly reduced, possibly due to longitudinal violent injury, which then leads to the disc protruding upward or downward into the interior of the vertebral body, resulting in a special type of disc herniation, which is clinically known as a teardrop fracture.
