I believe the condition to which you refer is "osteitis condensans
ilii," sometimes called "OCI." I've gathered some information for
you.

WHAT IS OSTEITIS CONDENSANS ILII?
======================================================================
"Q: I recently received a diagnosis of osteitis condensans ilii from
my rheumatologist. What is this?
A: Osteitis condensans ilii is a disorder that results in increased
density in the ilium, also called the iliac bone, in the pelvis. This
disorder usually causes no symptoms and needs no treatment. It's often
found incidentally on an X-ray of the pelvis or lower back done for
some other reason. The exact cause isn't known. Osteitis condensans
ilii isn't arthritis because it doesn't affect the joint.
Osteitis condensans ilii is more frequently found in women who've been
pregnant. It's thought that mechanical stress and increased blood flow
across the sacroiliac joint during pregnancy may be the cause. But
women who've never been pregnant and men also may get this condition."

WHAT CAUSES OSTEITIS CONDENSANS ILII?
======================================================================
"Osteitis Condensans Ilii... Felt to be a stress related phenomenon
secondary to instability at the symphysis pubis."
Homepage of Michael Tobin, Radiologist
http://www.mikety.net/Answers/osteitis-c.i.html
(NOTE: The symphysis pubis is the location where two large bones at
the front of the pelvis join.)
"Osteitis condensans ilii may be related to mechanical stress across
the sacroiliac joint and increased vascularity in pregnancy, although
other causes have also been suggested. A relationship to ankylosing
spondyitis may exist."
Amersham Health
http://www.amershamhealth.com/medcyclopaedia/Volume%20III%201/osteitis.asp
(NOTE: The sacroiliac joint is a large joint in the region of the
lower back where the pelvis joins with the spine. Ankylosing
spondylitis is a rheumatic disease that primarily affects the spine.)
"Osteitis condensans ilii typically occurs in young, multiparous
women. It is presumably linked to increased laxity and stress to the
joint during pregnancy and parturition."
The Physician and Sports Medicine Online
http://www.physsportsmed.com/issues/2002/11_02/chen.htm
(NOTE: Multiparous means "having given birth two or more times."
Parturition means "childbirth.")

HOW CAN OSTEITIS CONDENSANS ILII BE TREATED?
======================================================================
"You may wish to review some facts concerning Osteitis Condensans
Ilii...
May spontaneously resolve on cessation of stress or on surgical
stabilization at the symphysis pubis."
Homepage of Michael Tobin, Radiologist
http://www.mikety.net/Answers/osteitis-c.i.html
"Sacroiliac joint fusion is most commonly advocated as a surgical
treatment for degenerative sacroiliitis, inflammatory sacroiliitis,
iatrogenic instability of the sacroiliac joint, osteitis condensans
ilii (OCI), and traumatic fracture dislocation of the pelvis."

SUMMARY
======================================================================
Osteitis condensans ilii is a condition in which a portion of the
pelvis increases in density, sometimes without causing symptoms. It
can occur in males or in females, but is most common in women who have
borne several children. The condition may resolve itself
spontaneously, or may be treated surgically. As is the case with many
rheumatic diseases, non-steroidal anti-inflammatory drugs (NSAIDs) can
help with pain and inflammation, if present. Your rheumatologist is
your best source of information about treatment, since he or she is
familiar with the exact details of your condition.
