Ligamentum flavum tears are partial or complete disruptions of the elastic fibers within the ligamenta flava—paired, yellowish ligaments that connect the laminae of adjacent vertebrae from C2 to S1. Tears may occur acutely (e.g., after trauma) or develop gradually through degeneration, calcification, or ossification. When the ligament’s integrity is lost, patients may experience localized back pain, spinal instability, and, in severe cases, neural compression from infolding or hematoma formation WikipediaPubMed.
Anatomy of the Ligamentum Flavum
Structure and Location
Each ligamentum flavum is a short, thick band connecting the lamina of one vertebra to the lamina of the next, forming part of the posterior wall of the spinal canal. They begin at the junction of C2–C3 and continue to L5–S1, overlapping at each level and appearing yellow due to high elastin content Wikipedia.
Origin and Insertion
The ligamentum flavum arises from the anterior surface of the superior lamina and attaches to the posterior margin of the inferior lamina below. Medially it blends with the interspinous ligament and laterally with the facet joint capsule, creating a continuous posterior ligamentous complex Physiopedia.
Blood Supply
A rich network of small spinal branch arteries—branches of the posterior longitudinal and segmental arteries—penetrates the ligamentum flavum, ensuring a steady supply of oxygen and nutrients. This microvascular network also communicates with the internal and external vertebral venous plexuses Samarpan Physiotherapy Clinic.
Nerve Supply
Sensory innervation arises primarily from the sinuvertebral nerves—branches of the dorsal root ganglia—as well as from the adjacent posterior primary rami. These nerves transmit pain signals when the ligament is strained, torn, or inflamed Via Medica JournalsScienceDirect.
Key Functions
Preserve Upright Posture – Elastic recoil helps maintain the spine’s neutral alignment.
Prevent Hyperflexion – Resists excessive forward bending to protect spinal cord and discs.
Assist Return from Flexion – The high elastin content retracts the spine after bending Wikipedia.
Maintain Disc Tension – Keeps intervertebral discs under slight constant tension.
Prevent Canal Buckling – Elastic fibers prevent the ligament from bulging into the canal during extension.
Stabilize Posterior Elements – Complements other ligaments in forming the posterior ligamentous complex Wikipedia.
Types of Ligamentum Flavum Tears
Tears can be classified by mechanism, location, and morphology:
Acute Traumatic Tears: Caused by high-energy impacts (e.g., falls, vehicle collisions) leading to complete or segmental disruptions Radiopaedia.
Chronic Degenerative Tears: Result from long-term elastin fiber breakdown, calcification, or ossification (OLF) PubMed.
Partial-Thickness vs. Full-Thickness: Partial tears involve only some fiber depth; full tears span the entire thickness.
Longitudinal (Flap) Tears: Ligament flaps infold into the spinal canal, risking cord compression PubMed.
Hematoma-Associated Tears: Vascular rupture within a tear can produce an epidural hematoma ScienceDirect.
Spontaneous (Non-Traumatic) Tears: Occur without clear external injury, sometimes linked to connective tissue disorders ScienceDirect.
Causes of Ligamentum Flavum Tears
High-Energy Trauma: Falls, motor vehicle accidents, sports injuries.
Hyperflexion Forces: Sudden forward bending beyond normal limits.
Distraction Injuries: Vertebral separation forces during trauma.
Aging-Related Degeneration: Elastin fiber breakdown leading to weakening.
Ligamentous Ossification (OLF): Bony transformation reduces flexibility.
Calcification: Calcium deposits stiffen the ligament over time.
Repetitive Microtrauma: Chronic overuse in athletes or manual laborers.
Iatrogenic Injury: Post-laminectomy scar tears or epidural injections.
Connective Tissue Disorders: Ehlers-Danlos, Marfan syndrome.
Rheumatoid Arthritis: Autoimmune inflammation weakens ligaments.
Ankylosing Spondylitis: Chronic inflammation alters spinal ligaments.
Osteoporosis: Vertebral microfractures place extra strain on ligaments.
Degenerative Disc Disease: Alters spinal mechanics, increasing ligament load.
Facet Arthropathy: Joint degeneration shifts forces to ligamenta flava.
Spinal Stenosis: Hypertrophy of ligament increases tear risk.
Hemophilia: Bleeding into ligament predisposes to hematoma tears.
Long-Term Steroid Use: Reduces ligament tensile strength.
Obesity: Excess body weight increases spinal load.
Poor Posture: Chronic bending stresses ligaments unevenly.
Smoking: Impairs microvascular blood flow and healing.
