Degenerative Spinal Disease: Definition, Imaging Correlation, and Clinical Presentation

Definition and Scope

• Degenerative disc disease, facet joint arthrosis, and lumbar spinal stenosis are the principal components encompassed by the term “degenerative disease of the spine” (DDS). 1

Imaging Findings Versus Clinical Symptoms

• Imaging evidence of disc or facet degeneration is common in individuals without back pain; such findings alone do not establish a diagnosis of symptomatic spinal disease. 2
• Magnetic resonance imaging frequently reveals abnormalities (e.g., disc bulge, facet hypertrophy) in asymptomatic persons, underscoring the limited predictive value of imaging for pain. 2

Typical Symptomatic Presentations

• Patients with DDS may experience chronic axial spine pain arising from facet joint syndrome, sacroiliac joint syndrome, or intervertebral disc syndrome. 1
• Chronic radicular pain, caused by disc herniation/bulge or lumbar spinal stenosis, is another common manifestation of DDS. 1

Pain Severity and Duration in Clinical Trials

• In randomized trials of patients with DDS, the median baseline pain intensity is 6.8 / 10 on the visual analog scale, with a median symptom duration of 46 months prior to enrollment. 1

Diagnostic Approach

• Diagnosis should not rely solely on imaging; a thorough history and physical examination are essential to identify the true pain generator. 2
