Damage to the capital femoral epiphysis due to Frejka pillow treatment
FW Ilfeld and M Makin
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.
