Spondylolisthesis: AI-Powered Imaging Analysis

AI-powered spondylolisthesis detection on spine imaging. Grade vertebral slippage by Meyerding classification, assess pars defects, and evaluate neural compression. Multi-model analysis of spinal alignment.

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.
