Can you tell me what "pars defects at L5 with 4-5mm anterolisthesis of L5 on s1" mean?

In brief: Chronic fractures

A part of the L5 vertebral body, the pars articularis, has fractured on both sides and because of this the L5 vertebral body has been able to move forward in relation to s1, which is located directly below L5 (see picture).
These fractures are most often chronic and its possible may have been present even since childhood.
