- May 2, 2026The lumbar supraspinous ligament connects the lumbar spinous process tips, forming the outermost posterior passive restraint. It is often absent…
- May 2, 2026The lumbar intertransverse ligaments are thin membranous structures connecting adjacent transverse processes, providing coronal plane stability between motion segments. They…
- May 2, 2026The lumbar interspinous ligaments are the thickest in the spine, resisting the highest flexion loads at L4-L5 and L5-S1. Interspinous…
- May 2, 2026The lumbar ligamentum flavum is the thickest in the spine (3-5 mm normal), reflecting the highest flexion-extension loads. Its high…
- May 2, 2026The lumbar PLL widens at disc levels (providing some resistance to central disc herniation) and narrows at vertebral body levels,…
- May 2, 2026The lumbar ALL is a broad, thick band firmly adherent to the anterior vertebral bodies and anterior anulus fibrosus. It…
- May 2, 2026The intertransverse ligaments connect adjacent transverse processes throughout the spine, limiting lateral flexion. They are thin and poorly defined in…
- May 2, 2026The iliolumbar ligament connects the L5 (and L4) transverse processes to the iliac crest, acting as the primary stabiliser of…
- May 2, 2026The lumbar facet capsular ligaments at each level from L1-L2 through L5-S1 restrain the coupled rotation-lateral flexion movements and protect…
- May 2, 2026The lumbar ligamentum flavum is the thickest and most clinically significant portion of the flavum, forming the posterior spinal canal…
