About The Test
An X-ray that measures the flexion and extension of the lumbar spine uses a different technique but is colloquially referred to as an X-ray of the spine’s flexibility. It is a radiography examination that involves taking images of the lower back (lumbar spine) in flexed and bent positions. It serves the purpose of gauging the motion and stability of the lumbar spine in patients who have some degree of back pain or other related symptoms. In this article, we will provide an in-depth overview of the uses, risks, and limitations of lumbar spine flexion and extension X-rays.
What is a Lumbar Spine flexion and Extension X-Ray?
Flexion-Extension X-ray of the lumbar spine is an X-ray which provides a picture of the lower back while the patient’s body is in motion. Like most x-ray techniques, the method works by sending low levels of radiation to the region of interest. The procedure for the test includes taking x-ray pictures of the lumbar spine in two different poses:
- Flexion Position: The patient bends forward like in a bow and is evaluated for mobility of the spine.
- Extension Position: The patient bends backward and is evaluated in terms of how straight their back can be extended.
The images produced aid in the diagnosis and follow up of some spinal conditions like intervertebral degenerative disc disease, spinal stenosis, and spinal instability.
Types of X-rays of Lumbar Spine Flexion and Extension X-rays
As with any other X-ray, there are no specific types of lumbar spine flexion and extension X-rays because they are usually done with basic X-ray machines. There are, however, some allowances for patients with limited mobility.
List of Parameters
List of Parameters Considered During the Lumbar Spine Flexion and Extension X-ray
The radiologist or technician checks the following parameters during the examination:
- Spinal alignment: The positioning of the lumbar vertebrae as observed in an X-ray.
- Disc height: The height of the intervertebral discs located between the vertebrae.
- Spinal curvature: The amount of curve in the lumbar region of the spine.
- Vertebral fractures: The existence of any fractures to the vertebrae or other bonny abnormal growths.
Why This Test
Reasons for Taking a Lumbar Spine Flexion and Extension X-ray
The test is mostly prescribed to patients with these conditions:
- Degenerative disc disease: Wear and tear of the discs between the vertebrae.
- Spinal stenosis: The narrowing down of the spinal cavity.
- Spinal Instability: Where there is excessive or abnormal mobility within the spine.
- Scoliosis or kyphosis: Abnormal bends of the spinal column.
- Spinal fractures or trauma: Recent injuries or trauma of the spine.
When and Who Needs to Take a Lumbar Spine Flexion and Extension X-ray?
Patients who are likely to require a lumbar spine flexion and extension X-ray usually come with the following:
- Pain or stiffness in the back area.
- Weakness, numbness, or a tingling sensation in the legs.
- Difficulty in standing and/or walking due to back pain.
- Deformities of the spine like kyphosis or scoliosis.
- Trauma or injury to the spine region recently.
- Potential instability of the spine or disc degeneration.
For children and adults who are able to comprehend the directions and hold the necessary positions, this test is recommended.
Benefits
Benefits of Taking the Test
A lumbar spine flexion and extension X-ray has several pros including:
- Non-invasive: There are no cuts or injections required, thus it is non-invasive.
- Painless: No pain is expected during the test, yet some patients could feel a little uncomfortable.
- Quick and easy: The patient will typically take 15 to 30 minutes to complete the test, and it is very easy to conduct.
Preparation: The X-ray accurately diagnoses spinal abnormalities, providing excellent detail on the condition of the spine.
Illnesses Diagnosed with Lumbar Spine Flexion and Extension X-ray
These tests help in diagnosing conditions such as:
- Degenerative Disc Disease
- Spinal Stenosis
- Spinal Instability
- Scoliosis or Kyphosis
- Trauma or Fractures of the Spine
Preparing for test
Preparing for a Lumbar Spine Flexion and Extension X-ray
- Patients preparation includes:
- Put On Decent Attire: Put on clothing that is easy to move in.
- Take off glasses or jewellery: Glasses and jewellery should be taken off prior to the x-ray.
- Tell the technician about your condition: Inform the technician if there is a pregnancy or back injury.
Pre-requisites
There are not many pre-requisites for lumbar spine flexion and extension X-ray, although patients might need to:
- Not eat for several hours: Not eating or drinking for a couple of hours beforehand may be beneficial.
- Skip some medications: Refraining from taking medication like muscle relaxants should be done prior to the test.
- Ideal Time to Do the Lumbar Spine Flexion and Extension X-Rays
- It can be done at any time; however, mornings and early afternoons tend to have less chances of delays.
Eligibility
- Both adults and children who are able to follow directions are able to take the lumbar spine flexion and extension X-ray.
Procedure for Taking a Lumbar Spine Flexion and Extension X-ray
- Arrival and preparation: When arriving at the radiography location, patients should be in the hospital gown.
- Jewellery and Glasses Removal: Put aside any jewellery or glasses that could obstruct the X-ray pictures.
- Positioning: Assume the appropriate sitting or standing positions (flexion or extension positions) for the X-ray pictures.
- X-ray pictures: Try not to move for a few seconds while the X-ray images are recorded.
- Completion: Once the test is finalized the images will be examined by a radiologist.
Caution Before Performing the Test
Before trying to complete the test, the patients should:
- Advise the technician regarding the patients' medical conditions: Highlights conditions like pregnancy or any recent back injuries.
- Not take specific medications: Not taking muscle relaxants before the test would lead to a more accurate result.
- Adhere to the instruction guidelines: Following the technician's orders properly to prevent injury or discomfort.
Test Results
Results and Interpretations
Condition/Findings | Description | Interpretation |
---|---|---|
Normal Spinal Alignment | The vertebrae in the lumbar spine are properly aligned. | Normal spinal alignment, no evidence of spinal instability or deformities. |
Degenerative Disc Disease | Wear and tear on the intervertebral discs. | Degenerative disc disease, which may be causing back pain or stiffness. |
Spinal Stenosis | Narrowing of the spinal canal. | Spinal stenosis, which may be causing numbness, tingling, or weakness in the legs. |
Spinal Instability | Abnormal movement or instability in the spine. | Spinal instability, which may be causing back pain or stiffness. |
Scoliosis or Kyphosis | Abnormal curvature of the spine. | Scoliosis or kyphosis, which may be causing back pain or stiffness. |
FAQs
What is a lumbar spine flexion and extension X-ray?
A lumbar spine flexion and extension X-ray is an imaging procedure which captures the lower back area while the individual bends forward and backward for the purpose of evaluating the range of motion and overall condition of the spine.
Why is the test performed?
This imaging test is done as part of the diagnosis and tracking of progression of spinal disorders such as degenerative disc disease, a form of spinal stenosis, and spinal instability.
What are the risks and limitations of the test?
Exposure to radiation, resulting pain, and low precision are some of the drawbacks and hazards of this examination.
How long does the test take?
The duration is roughly 15-30 minutes for this test in general.
What are the benefits of the test?
Others include referral results being rapid, non-invasive, pain-free, and easy to receive for the patients.
