Vertebrogenic Low Back Pain
This article is a stub.
The pain is often inflammatory in nature and can mimic spondyloarthritis in that there is commonly night pain and prolonged morning stiffness. The pain is often midline rather than lateralised as is the case in other causes of chronic low back pain. The pain can refer to the buttocks. It is not typical for pain to refer past the knee. There may be an absence of pain with extension.
There may be a mixed picture as endplate pathology commonly co-exists with annular tears which is transmitted largely via the sinuvertebral nerve rather than the basivertebral nerve. Irritation of nerve roots such as in the presence of disc herniation can further mix the clinical features.
