Creation of the proximal and distal bone cuts in the van Bosse reorientational proximal femoral osteotomies for correction of hip contractures. A and B, Proximal osteotomy is parallel and 5 to 8 mm distal to the seating chisel blade. Distal osteotomy is perpendicular to the shaft of the distal fragment so that the two cuts meet medially as the apex of the wedge. C, Second osteotomy cut is perpendicular to the shaft of the distal fragment. D, Blade plate fixation.
