Anatomical Presentation Of artificial, disc, replacement, lumbar Artificial Disc Replacement

Description

Anterior lumbar anatomy is presented with an artificial intervertebral disc seated at the lumbosacral junction, between the inferior endplate of L5 and the superior endplate of S1, immediately superior to the sacral promontory. The sequence keeps an anterior orientation, so the prosthetic disc reads in line with the anterior longitudinal ligament and the ventral margins of the vertebral bodies. As the camera holds and subtly advances, the implant’s metallic endplates and central core are distinguished from adjacent cortical bone, clarifying its midline placement between left and right pedicles and the lateral margins of the vertebral body. Motion is restrained and deliberate, reinforcing the device as a load-bearing spacer rather than a fused segment. Clinically, this is the most common target level for lumbar artificial disc replacement because degenerative disc disease at L5 to S1 can produce mechanical low back pain while preserving facet joint integrity. An anterior approach places the implant through the retroperitoneal corridor, where the left common iliac vein and the hypogastric plexus lie close to the operative field, and those relationships explain why precise midline positioning matters. The animated progression clarifies how disc height restoration reopens the intervertebral foramina and maintains segmental motion, a concept that is harder to communicate in a single still. Use it in spine surgery lectures covering anterior lumbar interbody exposure, arthroplasty implant design, and level selection for L5 to S1 versus L4 to L5. It also fits orthopaedic device training, patient education modules comparing arthroplasty with fusion, and medical publishing figures that need a clean anterior view of a lumbosacral prosthetic disc in situ.
