What is facet joint disorder

People's waist is strong, so strong that it can carry hundreds of kilograms of objects, but people's waist is also fragile, so fragile that when some diseases attack, people dare not move at all. Among the many lumbar diseases, although facet joint disorder is not the most common, its harm to patients cannot be ignored by patients. However, some friends do not have special cases for facet joint disorder. This article will introduce in detail what facet joint disorder is.

There is a type of low back injury that causes unusually severe low back pain immediately after the injury. Patients often lie on their side with their backs bent, unable to straighten, and dare not move for fear of being touched by others. They are often misdiagnosed as having acute lumbar muscle sprain. In fact, the exact diagnosis should be lumbar synovial incarceration, or lumbar posterior joint disorder, commonly known as facet joint disorder.

The posterior joint of the human lumbar vertebra is composed of the inferior articular process of the upper vertebra and the superior articular process of the lower vertebra. The small joint surface is covered with cartilage and has a small joint cavity, which is surrounded by a joint capsule. The inner layer is synovial membrane, which can secrete synovial fluid to facilitate joint movement. The arrangement of the articular surfaces of the lumbar vertebrae articular processes is semi-frontal and semi-sagittal, and its cross-section is approximately arc-shaped, which is flexible in extension, flexion, lateral flexion and rotation. Because the lumbosacral region has a larger range of motion, the posterior lumbosacral facet joints are also relatively loose.

When the waist is suddenly twisted, bent forward, or rotated, the spaces between the small joints open, the negative pressure inside the joints increases, and the synovial membrane can enter the joint spaces. If the synovium of the joint is clamped in the joint space during flexion and extension, it will cause synovial incarceration of the facet joint or facet joint subluxation. The synovium can be severely damaged by compression of the joint. The synovium and joint capsule are rich in sensory and motor nerve fibers, which cause severe pain and reflex muscle spasms. If the incarceration is not relieved in time, chronic severe low back pain and arthritis will occur.

After knowing what facet joint disorder is, patients who want to get rid of facet joint disorder can use surgical treatment to solve the problem. At present, surgical treatment is a relatively good treatment method for this disease. Of course, if the patient does not want to use surgical treatment, he can also communicate with his doctor to see what the doctor recommends.
