One of the complications of lupus is its effect on bone tissue. Sometimes, an insufficient amount of blood reaches the bone, causing it to deteriorate and break. This is most commonly seen in the hip joint. About 10 percent of individuals with lupus develop bone tissue death.
Bone tissue death and osteoporosis can also be caused by the medications taken for lupus. Corticosteroids also eat away at the bone, causing osteoporosis and breakage.
