Question 1

grade1 anterolisthesis of l5 on s1, congenital anterior wedge deformities of t12 l1 present. bilateral l5 pars interarticularis defects. means what?

Accepted Answer

The tiny plates: which help stabilize the veterbrae one with another are missing at the 5th Lumbar Veertebral level causing a SLIPPAGE of the L-5 veterbrae on the sacrum (S1).  this is associated with a smaller height of two of the veterbrae ABOVE the defect  T-12 (the lowest chest (thoracic) veterbrae and the highest Lumbar (low back) veterbrae..... Hope this helps..difficult to explain without a "pointer"
