Forward subluxation of the body of a vertebra on the vertebra below.
Epidemiology:
1) 3% of the adults
2) more common in women
Pathology:
1) not associated with changes in lumbar disc height
2) most commmon at L4 [2]
3) factors related to anterolisthesis
a) increased pedicle-facet angle [1]
b) W-shaped facet joint [1]
c) decrease in facet angle of caudal cervical facet joints [3]
4) loss of anterior cervical disc height promotes anterolisthesis [3]
