In Reply to: Parr's fracture posted by Cindy on February 06, 1998 at 21:49:11:

: I am interested in any information on "Parr's fracture" in relationship to the 5th lumbar vertebrae. This has been suggested as a possibility for the back problems my son has had. Possibly congenital or from old injury. This seems to be a very uncommon condition. A worried mom would appreciate any information.

Dear Cindy:

A Pars fracture is a fracture in the bony element that connects the superior and inferior articular processes of a vertebra.

This causes instability with resultant movement of a vertebral body forward with respect to the adjacent vertebral bodies. This can cause low back pain as well as lower extremity pain. Some people have congenital problems with the pars and this results in problems. Other people can injur their back and as such acquire a pars fracture. The treatment is surgical and there are many methods to approach surgery.

I hope this helps. If you have any further questions please do not hesitate to write back.

Good Luck !
