Detorsions varus osteotomy is one of the most important treatments of congenital dislocation of hip.
Many techniques have been trying even now, but this operation needs the skilled operator and long operative time. And in some cases, uncomfortable result may be present after operation.
Now we devise and favor a means of this operation, which is not lost time and obtain easier expected angle.
Deciding corrective angle, we place our clinical views with roentgenograms. We use a few triangle metals and chart at operation. The triangle metals class from 5 degrees to 90 degrees. The chart list a length of bone wedge's base at varus osteotomy and a distance of distal femoral lateral rotation at detorsion osteotomy, by measuring diameter of osteotomy part on roentgenogram.
