Spinal spondylolisthesis is one of the common orthopaedic diseases commonly found in the lumbar spine. The initial symptoms of lumbar spondylolisthesis are not obvious, and it may be that only the filming can reveal the disease and it is easy to be ignored. Experts from the Bolly Orthopaedic Hospital said that the symptoms of spinal spondylolisthesis will increase, and there will be symptoms such as low back pain, lower limb pain, numbness, weakness, etc., which will lead to depression of the waist, anterior abdomen, and even shortening of the trunk and swinging when walking. Patients must go to the profession in time. Orthopedic hospital for symptomatic treatment.

So, what causes the spine to slip?

1, congenital dysplasia

The lumbar vertebrae have vertebral body and vertebral arch ossification center. Each vertebral arch has two ossification centers, one of which develops as superior articular process and pedicle, and the other develops into lower articular process, lamina and spinous process. Half of it, if there is no healing between the two, it will cause the congenital isthmus to collapse and cause the spine to slip.

2, fatigue fracture or chronic strain

When the human body is standing, the weight of the lower lumbar spine is large, which causes the component force of the forward movement to act on the isthmus with relatively weak bone. Long-term repeated action can lead to fatigue fracture and chronic strain damage.

3, trauma

Acute trauma, extensor trauma, acute fractures can lead to spondylolisthesis, which is more common in carrying heavy loads, weightlifting, football, physical training, trauma, wear and tear.

4, degenerative factors

Due to long-term sustained lower back instability or increased stress, the corresponding small joints wear, degenerative changes, intervertebral disc degeneration, intervertebral instability, anterior ligament relaxation, and gradually slip, but the isthmus remains intact, Called pseudo-slip, usually occurs after the age of 50, this slip is usually accompanied by lumbar spinal stenosis.

5, pathological fracture

Mostly due to systemic or local tumors or inflammatory lesions, involving the vertebral arch, isthmus, and articular processes, the structural stability of the vertebral body is lost, and pathological spondylolisthesis occurs.
