The II type deformities according Kalamchi after avascular necrosis of the femoral
head is the most difficult for operative correction. We performed the posterior
rotational hip osteotomy for treatment of this pathology in 14 cases. The indications
to operation were: the multidimensional deformities of the proximal part of the
femur at the age 10-14 years (8 cases) and removing a plane of progressing
deformation in functional less significant at the age 6-9 years (6 cases). The mean
value of the epiphyseal quotient increased from 48 to 98. Its improvement was
marked and further during all time till the moment of bone maturing. The epiphysealneck
quotient increased to 99 against 58 before the intervention, the neck-shaft angle
became 132 Against 122. The Viberg angle increased from 18 to 31. This operation
can be very useful in treatment of the II type deformities of the proximal part of the
femur in children. Advantages of operation are absense of negative influence on a
growth plate, lengthening of the femoral neck, improvement of a congruity in a hip
joint.
