What is a X-RAY LS SPINE FLEXION & EXTENSION?

X-Ray LS Spine Flexion & Extension is a functional radiographic examination that evaluates the lower spine while bending forward and backward. The examination assesses spinal movement, alignment, and stability, helping diagnose spinal instability, spondylolisthesis, degenerative changes, and other lumbar spine abnormalities.

FAQs

What is an X-Ray LS Spine Flexion & Extension?

X-Ray LS Spine Flexion & Extension is a specialized X-ray examination that captures images of the lower spine while bending forward (flexion) and backward (extension) to assess spinal movement and stability.

Why is this X-ray performed?

It is performed to evaluate chronic lower back pain, spinal instability, spondylolisthesis, degenerative disc disease, and other conditions affecting the lumbar spine.

Which structures are examined during the test?

The examination visualizes the lumbar vertebrae (L1–L5), lumbosacral junction (L5–S1), intervertebral disc spaces, facet joints, and overall spinal alignment.

Why are both flexion and extension views important?

Comparing both positions helps identify abnormal spinal movement, instability, vertebral slippage, and alignment changes that may not be visible on routine X-rays.

Can this X-ray detect spinal instability?

Yes. It is one of the most common imaging tests used to evaluate lumbar spinal instability.
