Comparison of femoral and innominate osteotomies for the treatment of Legg-Calve-Perthes disease

The outcomes of forty-two femoral osteotomies and forty-nine innominate
osteotomies for the treatment of Catterall grade-III or IV
Legg-Calve-Perthes disease were compared. The average length of follow-up
was nine years (range, three to seventeen years). For the patients who were
less than ten years old at the onset of the disease, there was no
difference in the results of the two procedures, even when the results were
analyzed according to age. However, the center-edge angle, neck-shaft
angle, lengths of the limbs, range of abduction, and total range of motion
were closer to normal after an innominate osteotomy. There was no
difference in the ratings when the results of the two operations were
compared according to the several parameters that have been proved to be
associated with the long-term outcome for hips in patients who have
Legg-Calve-Perthes disease. However, the innominate osteotomy seemed to be
the better procedure when involvement of the growth plate was likely to
cause coxa vara or a substantial discrepancy in the lengths of the limbs.
The patients who were more than ten years old at the onset of the disease
had a poor result with either procedure.
