Transient osteoporosis of pregnancy: A case report and review of anesthetic implications

Transient osteoporosis of pregnancy (TOP) is a rare and self-limited disease with an unknown etiology. A 29-year-old woman complained at her 39 th week of pregnancy of focalized pain in the right hip with functional disability and instability. Pain increased during the early puerperium after removal of the epidural catheter. The X-ray and magnetic resonance imaging (MRI) showed a displaced intracapsular fracture in the right femur, which needed surgical correction. The patient underwent urgent orthopedic surgery. We reviewed the anesthetic implications of this rare disease, particularly the use of a regional technique that removes the restrictive effect of the hip pain, and therefore increases the risk of a fracture
