What is the relationship between lumbar facet joint disorders and the quadratus lumborum muscle?
I have been experiencing severe lower back pain recently, especially during physical activities. After visiting the hospital, I was diagnosed with lumbar facet joint dysfunction. I would like to know what relationship exists between lumbar facet joint dysfunction and the quadratus lumborum muscle?
Doctor's answer (1)
The relationship between lumbar facet joint disorders and the quadratus lumborum muscle is primarily reflected in their interrelated pathophysiological mechanisms.
1. Location and Function: The quadratus lumborum is a deep muscle located in the lower back, primarily responsible for stabilizing the lumbar spine and assisting in lumbar movements. Lumbar facet joint disorders refer to abnormalities in the small joints of the lumbar spine, which can cause pain and discomfort.
2. Mutual Influence: The quadratus lumborum is a deep muscle located on both sides of the lumbar spine and plays an important role in maintaining spinal stability. In the presence of lumbar facet joint disorders, the quadratus lumborum may become excessively tense or contract in an attempt to compensate for the impaired joint function, potentially leading to muscle spasms, pain, and shortening, thus creating a vicious cycle of muscle tension and pain. Conversely, if the quadratus lumborum itself is tense, spasmodic, or inflamed, it can affect the normal movement of the lumbar facet joints, increase joint stress, accelerate joint wear, and thereby trigger or exacerbate symptoms of lumbar facet joint disorders.
3. Treatment Approaches: For both lumbar facet joint disorders and quadratus lumborum dysfunction, treatment options may include physical therapy, manual correction, and pharmacological therapy. These treatments aim to relieve pain, restore lumbar stability, and improve the function of the quadratus lumborum muscle.
