What Is Lumbar Spinal Instability?
Lumbar spinal instability refers to excessive or abnormal movement between two or more vertebrae in the lower spine. This can be due to degenerative disc disease, trauma, spinal surgery, or congenital issues. When the spine becomes unstable, it can compress nerves, cause inflammation, and lead to a variety of symptoms.

Common Symptoms of Lumbar Spinal Instability
Before jumping into diagnostics, it’s important to recognize the common symptoms, which include:
Lower back pain that worsens with standing or activity
A sensation of “catching” or “locking” in the back
Numbness or tingling in the legs
Muscle weakness
Limited flexibility or range of motion
If you’re experiencing these symptoms, it’s time to consult a spine specialist at a trusted center like Ishaan Ortho & Spine.
Clinical Examination
The first step in diagnosing lumbar spinal instability is a detailed physical examination by a spine expert. This includes:
Medical history review: Understanding any past injuries, surgeries, or chronic issues
Palpation: Feeling the spine and surrounding muscles for tenderness or irregularities
Range of motion tests: Observing how your spine moves when you bend, twist, or stretch
Neurological tests: Checking reflexes, muscle strength, and sensory function
These tests help identify signs of nerve compression or spinal misalignment, which are key indicators of instability.
Imaging Tests Used to Diagnose Lumbar Spinal Instability
1. X-rays
Dynamic X-rays (flexion and extension views) are the most commonly used imaging test to detect lumbar instability. They are taken while the patient bends forward and backward. The doctor looks for abnormal vertebral motion, which suggests instability.

2. MRI (Magnetic Resonance Imaging)
An MRI scan provides detailed images of soft tissues, including intervertebral discs, nerves, and spinal ligaments. It is especially useful in detecting conditions like degenerative disc disease, herniated discs, or spinal stenosis, which may contribute to instability.

3. CT Scan (Computed Tomography)
A CT scan gives high-resolution images of the bones in the lumbar spine. It helps identify bony abnormalities, fractures, or facet joint issues that could be causing instability.

4. Discography
In some complex cases, a discography may be recommended. This involves injecting contrast dye into a spinal disc to assess if the disc is the source of pain. It’s usually reserved for patients being considered for spinal fusion surgery.

Differential Diagnosis: Ruling Out Other Conditions
Lumbar spinal instability can sometimes mimic other spinal disorders. The diagnosis process also involves ruling out:
Lumbar disc herniation
Spinal stenosis
Sciatica
Spondylolisthesis
That’s why it’s crucial to get evaluated by a spine expert who can correctly identify the root cause of your symptoms.
When Should You See a Spine Specialist?
You should seek medical help if you have:
Persistent or worsening lower back pain
Pain that radiates to your legs
Difficulty walking or standing
Muscle spasms or stiffness in the lower back
A history of spinal trauma or surgery
Early diagnosis not only improves outcomes but also allows for non-surgical treatment options, such as physical therapy, core strengthening, and pain management.
Conclusion
Lumbar spinal instability is a serious yet treatable condition. Diagnosis begins with a clinical exam and is confirmed using advanced imaging techniques like X-rays, MRIs, and CT scans. The sooner you receive an accurate diagnosis, the better your chances of effective recovery.
