LUMBAR SPINE FLEXION & EXTENSION X-RAY SCAN

Overview

Persistent lower-back pain can limit daily life. Cadabams Diagnostics offers the XR – LUMBAR SPINE FLEXION & EXT, a quick X-ray study that captures your lumbar spine while you bend forward (flexion) and backward (extension). These two dynamic images spot hidden instabilities or abnormal motion that standard static films may miss. If you need a trusted centre near you, read on to learn how the test works, when it is needed, and how to book it effortlessly.

What is Lumbar Spine Flexion and Extension Views?

The lumbar spine flexion and extension views are specialised X-rays that record the movement of the lower five vertebrae (L1–L5) and the sacrum.

• Flexion view: taken while you bend forward as far as comfortable.
• Extension view: taken while you bend backward.
  Comparing both images reveals any excessive or restricted motion, misalignment, or signs of spinal instability.

Our radiologists evaluate:

• Intervertebral angle change between flexion and extension.
• Translation (slippage) of vertebrae.
• Disc-space height loss or wedging.
• Pars interarticularis defects.
• Spinal curvature (lordosis) variation.

• Confirm or rule out spinal instability.
• Monitor progress after physiotherapy or surgery.
• Detect latent fractures not visible on static films.
• Provide objective data for insurance or medico-legal cases.

You may be advised to take this test if you have:

• Chronic lower-back pain lasting >6 weeks.
• Suspected spondylolisthesis or spondylolysis.
• Post-injury checks after trauma or fall.
• Pre-surgical screening for spinal fusion.
  Athletes, manual labourers, senior citizens, and anyone with prior spinal surgery are common candidates.

Benefits of Taking the Lumbar Spine Flexion & Extension X-Ray Scan

• Non-invasive and completed in <15 minutes.
• Real-time motion assessment.
• Guides precise treatment plans—surgery vs. conservative care.
• Same-day digital reports via Cadabams Diagnostics app.

Illnesses Diagnosed with Lumbar Spine Flexion & Extension X-Ray Scan

• Degenerative spondylolisthesis
• Isthmic spondylolysis
• Facet joint arthropathy
• Lumbar spinal stenosis (dynamic narrowing)
• Post-operative pseudoarthrosis

Do’s

• Wear loose, metal-free clothing.
• Remove belts, jewellery, and wallets.
• Bring previous imaging reports for comparison.

Don’ts

• No fasting required.
• Avoid applying creams or ointments on the lower back.

Pre-requisites

• Doctor’s prescription stating the need for flexion/extension views.
• Valid ID proof for registration.
• Pregnancy declaration form (for women of child-bearing age).

Best Time to Take the Test

Morning slots are ideal—muscles are less fatigued, enabling better bending range. Walk-in and home-collection bookings start at 7:30 a.m.

Eligibility

Age: 12 years and above.
Weight limit: Up to 150 kg for standard X-ray table.
Special arrangements are available for wheelchair users—alert the front desk while booking.

Procedure for Taking Lumbar Spine Flexion and Extension Views

1. Registration: quick KYC at the counter.
2. Changing: wear a provided gown if needed.
3. Positioning:

• First lateral X-ray while standing and bending forward (flexion).
• Second lateral X-ray while standing and bending backward (extension).

1. Capture: each exposure lasts 1–2 seconds.
2. Verification: technician checks image quality on the spot.
   Total time: 10–15 minutes.

Caution Before Taking the Test

• Inform if pregnant or have a metallic implant (rods, screws).
• Pain medications: take as prescribed, but avoid muscle relaxants just before the test—they can mask abnormal movement.
• Children: parental consent mandatory.
  tors—they may create artefacts.
