Avascular necrosis of the bilateral femoral head with pregnancy: A case report

Abstract

Osteonecrosis, also called avascular necrosis, of the femoral head is a pathologic process resulting from an inadequate blood supply. The death of cells in bone tissue can cause the collapse of the affected joint. It is a progressive disease primarily affecting adults in middle age and can lead to substantial loss of joint function. Osteonecrosis of the femoral head during or just after pregnancy is a rare clinical entity. Although many causes of femoral head osteonecrosis have been identified, little is known about pregnancy as an etiological factor. Presently described is the case of a 30-year-old female with bilateral osteonecrosis of the femoral head that developed during the peripartum period.
