Abstract
Femoral osteotomies of pelvic support was performed in patients with hip instability, axial malalignment and leg length-discrepancy. Possibly inspired by techniques previously described by Schanz, Milch. Ilizarov and Rozbruch, 5 patients had neonatal hip sepsis sequelae (2 cases and 3 hips), septic arthritis (2 cases) and proximal femoral focal deficiency (1 case) were reviewed.
X-Rays of both limbs in neutral position to measure the deviation degree of the mechanical axis and other with the limb in maximal adduction to measure the osteotomy level of the pelvic support were taken before surgery.
The technique consists of a proximal femoral osteotomy in the intersecting axis in maximal adduction and a second distal metaphyseal osteotomy which allows the compensation of the mechanical axis and the elongation of the limb. Both are fixed with an external fixator.
This technique gives a pelvic support improving the Trendelemburg gait and tighter abductors muscles due to simultaneous correction of LLD and knee alignment.
