The S-rOM modular femoral stem in dysplasia of the hip

Abstract

Abnormal femoral neck anteversion, previous proximal femoral osteotomies, and small femoral canals with metaphyseal/diaphyseal mismatch are commonly seen in patients with developmental dysplasia of the hip (DDH) and are ideal indications for using a modular femoral stem. The torsional stability of the fluted modular stem makes it the implant of choice for subtrochanteric osteotomy stabilization for reduction of high-riding DDH. Modularity optimizes proximal and distal implant stability while permitting adjustments to anteversion, offset, and leg length to provide custom biomechanical reconstruction of the DDH hip. Clinical results with few complications can be achieved when using this stem in complex DDH surgery.
