In brief: Patients

Patients who do not respond to conservative treatment for spondylolysis (fracture of pars interarticularis, that is the hook holding your spine bones together) may benefit from surgery.
Surgery fuses the spine in order to prevent movement across the fracture and prevent the spine from slipping apart (spondylolithesis). For more information on spondylolysis, spondylolithesis and spinal fusion please see my health guides. Good luck!

In brief: As

As you know, spondylolysis is a defect in the bony arch of one or more vertebral bodies (it's similar to having part of a bridge's arch cut away).
This defect sometimes allows a vertebra to slip forward on the vertebra beneath it, which leads to a condition called spondylolisthesis. Both spondylolysis and spondylolisthesis can cause chronic back pain, and many patients also develop sciatica. Spondylolysis is generally believed to result from stress fractures in vertebral arches that are thinner than normal. Thus, the condition is usually acquired. However, the tendency to have thin vertebral arches appears to be an inherited one. So, while spondylolysis is something that usually develops in adolescence, the tendency to have this condition is genetic in many cases -- hence, a "birth defect." i hope that helps!
