Question explored with the scientific record
multilevel facet arthropathy and marginal endplate osteophyte formation through lumbar spine
The short version: these two findings are separate signs of the same aging spine, not cause and effect.
Multilevel facet arthropathy means the small joints at the back of each vertebra are wearing down. Marginal endplate osteophytes are bone spurs growing at the edges of the vertebral bodies, where the discs attach. Both are common wear-and-tear changes that often appear together in the same spine [2]. The retrieved studies show they frequently coexist with disc degeneration and other degenerative changes, but none of them directly tested whether one causes the other [3][4].
What the evidence does show is that both are linked to instability. One study found that facet joint degeneration and disc degeneration both track with abnormal motion in the lumbar spine [3]. Another found that facet joint fluid on MRI predicts instability seen on flexion-extension X-rays [6]. The mechanical stress from a degenerating disc likely shifts load onto the facet joints, and the body responds by growing bone spurs at the endplates to stabilize the segment [2][5].
The practical question is whether these findings explain your pain. They might not. A study of asymptomatic adolescent athletes found facet arthropathy in about 7 in 10 of them, with no pain at all [1]. Another study found that vertebral osteophytes were not significantly associated with chronic low back pain after adjustment [7]. The imaging findings are real, but they are not proof that they are the source of your symptoms.
My call: these are related degenerative changes, not cause and effect. The evidence is moderate that they coexist and share mechanical drivers, but weak on whether either one causes pain. Confidence: moderate.
