Numerous possible complications can occur, including redislocation, stiffness of the hip, infection, blood loss, and, possibly the most devastating, avascular necrosis of the femoral head. The rate of femoral head necrosis varies substantially; depending on the study, it may be anywhere from 0% to 73%. Numerous studies demonstrate that extreme abduction, especially when combined with extension and internal rotation, results in a higher rate of avascular necrosis.
