Transient osteoporosis of hip and lumbar spine in pregnancy.

Transient osteoporosis of the hip in pregnancy is a relatively rare disorder characterized by disabling pain in the hip without prior trauma and by striking radiographic evidence of osteopenia that is limited to the hip [1].The mean interval from the onset of symptoms until complete clinical resolution ranges from 4 to 24 months. It is a diagnosis of exclusion and despite a benign prognosis, the long clinical course causes prolonged disability. We present a case of a primigravida at term with transient osteoporosis of both the hip joints and the lumbar spine.
