The primary function of the lumbar facet joints is to resist forces induced by rotation. These joints play a critical role in stabilizing the lumbar spine during movement, particularly when the body rotates. The facet joints, which are synovial joints located at the back of the vertebrae, guide the movement of the spine and help prevent excessive motion that could lead to injury.

During rotational movements, the lumbar facet joints provide mechanical resistance, limiting the degree of rotation that occurs between vertebrae. This is essential for maintaining spinal integrity and proper alignment, especially considering that the lumbar region bears significant loads and is prone to injury.

While the lumbar facet joints also resist forces associated with flexion, extension, and lateral bending to some extent, their primary function in resisting rotational forces is critical in preventing conditions such as facet joint syndrome or chronic low back pain related to excessive rotation.
