Damage to the capital femoral epiphysis due to Frejka pillow treatment.
Seven cases of damage to the capital femoral epiphysis in seven infants with congenital dysplasis, subluxation, or dislocation of the hip treated with a Frejka pillow splint are described. The pillow was first applied shortly after birth (up to four months of age) and was continued for three to six months. The roentgenographic changes in the femoral head and neck were consistent with either avascular necrosis of the femoral head or a growth disturbance causing alteration of the normal angle of the neck and shortening of the affected femur.
