Lumbar degenerative spondylolisthesis (LDS) is a prevalent condition among the elderly population. Magnetic resonance imaging (MRI) is often the first investigative modality if indicated clinically. However, the standard supine position used during an MRI may fail to detect dynamic instability. In such cases, the presence of facet joint fluid is a reliable sign, and further investigation, such as stress radiographs, should be conducted to confirm dynamic instability. Here, we present a typical case demonstrating the importance of this finding. A patient presented with neurological claudication, and an MRI was initially unremarkable except for the presence of lumbar facet joint fluid. This finding prompted us to conduct stress radiographs, which eventually confirmed dynamic instability.
腰椎退行性滑脱（LDS）在老年人群中是一种常见病症。如果临床有指征，磁共振成像（MRI）通常是首要的检查方式。然而，MRI检查时使用的标准仰卧位可能无法检测到动态不稳定。在这种情况下，小关节积液的存在是一个可靠的征象，应进行进一步检查，如应力位X线片，以确认动态不稳定。在此，我们展示一个典型病例来说明这一发现的重要性。一名患者出现神经源性间歇性跛行，最初的MRI检查除了腰椎小关节积液外无明显异常。这一发现促使我们进行应力位X线片检查，最终证实了动态不稳定。
