<p class="p__0">The posterior longitudinal ligament (PLL) affords just weak midline support, particularly at L4-5 and L5-S1, as it is a narrow structure connected to the annulus. The anterior and middle fibers of the annulus are most numerous anteriorly and laterally however deficient posteriorly, where the majority of the fibers are connected to the cartilage plate.</p>

<p class="p__1">The anterior column (black dotted line) includes the anterior spinal ligament, the anterior annulus fibrosus (AF), the intervertebral disc, and the anterior two thirds of the vertebral bodies. The middle column (red dotted line) includes the posterior element of the vertebral bodies, the posterior annulus fibrosus, and the posterior longitudinal ligament (PLL).</p>
<br>
<p class="p__2">ALL = anterior longitudinal ligament; ISL = interspinous ligament; LF = ligamentum flavum; NP = nucleus pulposus; SSL = supraspinous ligament. The annular fibers are strongly attached to the vertebral bodies and are set up in lamellae. This annular arrangement permits limiting vertebral motions, enhanced by investing ligaments. Back Vertebral Ligaments The ALL covers the ventral surfaces of lumbar vertebral bodies and discs.</p>

<br>
<p class="p__3">The ALL maintains the stability of the joints and limitations extension. The PLL lies within the vertebral canal over the posterior surface area of the vertebral bodies and discs. It operates to limit flexion of the vertebral column, other than at the lower L-spine, where it is narrow and weak. The supraspinous ligament signs up with the ideas of the spinous procedures of nearby vertebrae from L1-L3.</p>

<p class="p__4">Often described together as the interspinous/supraspinous ligament complex, they weakly resist spine separation and flexion. Need More Info? (LF) bridges the interlaminar period, connecting to the interspinous ligament medially and the facet pill laterally, forming the posterior wall of the vertebral canal. It has a broad accessory to the undersurface of the remarkable lamina and inserts onto the leading edge of the inferior lamina.</p>
<br>
<p class="p__5">It maintains consistent disc tension. The intertransverse ligament joins the transverse procedures of surrounding vertebrae and resists lateral flexing of the trunk. The iliolumbar ligament arises from the suggestion of the L5 transverse process and connects to the posterior part of the inner lip of the iliac crest. It assists the lateral lumbosacral ligament and the ligaments discussed above stabilize the lumbosacral joint (see the following images).</p>
