Spondylolisthesis: AI-Powered Imaging Assessment
Upload spine X-rays or MRI for AI assessment of vertebral slippage, Meyerding grading, and associated spinal stenosis.
Overview
Spondylolisthesis is the forward displacement of one vertebral body relative to the one below. It is classified by etiology (isthmic with pars defect, degenerative, traumatic) and graded by severity using the Meyerding classification. Imaging evaluates the degree of slippage, pars integrity, disc status, and resultant neural compression. Our AI consortium assesses slippage grade, identifies pars defects, and evaluates associated stenosis and nerve root compression at the affected level.
Common Symptoms
- Low back pain worsening with extension and activity
- Hamstring tightness and altered gait
- Radicular leg pain from nerve root compression
- Visible or palpable step-off in the lower back
- Pain with prolonged standing or walking
- Neurogenic claudication symptoms in degenerative type
Key Imaging Findings
- Anterior translation of vertebral body relative to the one below
- Meyerding grading: Grade I (0-25%), Grade II (25-50%), Grade III (50-75%), Grade IV (75-100%)
- Pars interarticularis defect on oblique views or CT
- Associated disc degeneration at the spondylolisthesis level
- Central or foraminal stenosis from the slippage
- Reactive bone marrow changes at the pars defect
Frequently Asked Questions
What is the difference between isthmic and degenerative spondylolisthesis?
Isthmic spondylolisthesis results from a pars interarticularis defect (stress fracture), most common at L5-S1 in young patients. Degenerative spondylolisthesis results from facet and disc degeneration without a pars defect, most common at L4-L5 in older patients. Our AI differentiates these types based on imaging findings.
