A retrolisthesis is a posterior displacement of one vertebral body with respect to the subjacent vertebra to a degree less than a luxation (dislocation). Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views where care has been taken to expose for a true lateral view without any rotation offer the best diagnostic ...
Backward displacement is called retrolisthesis. Lateral displacement is called lateral listhesis [4] or laterolisthesis. [5] A hangman's fracture is a specific type of spondylolisthesis where the second cervical vertebra (C2) is displaced anteriorly relative to the C3 vertebra due to fractures of the C2 vertebra's pedicles.
The reverse of this condition is retrolisthesis where one vertebra slips backward onto another. The vertebral pedicle is often used as a radiographic marker and entry point in vertebroplasty, kyphoplasty, and spinal fusion procedures. The arcuate foramen is a common anatomical variation more frequently seen in females.
The term comes from Greek lordos 'bent backward'. [5] Lordosis in the human spine makes it easier for humans to bring the bulk of their mass over the pelvis. This allows for a much more efficient walking gait than that of other primates, whose inflexible spines cause them to resort to an inefficient forward-leaning "bent-knee, bent-waist" gait ...
The last decade of studies on Modic changes have shown that Modic changes are associated with many treatment-resistant pain episodes and may result in patients entering a state of chronic low back pain.
Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. ...
