Which stem in total hip arthroplasty for developmental hip dysplasia? A comparative study using  a 3D CT-based software for pre-operative surgical planning

ConclusionsStem choice in developmental hip dysplasia is mainly driven by appropriate combined anteversion, which is dependent on the coronal and axial femoral morphologies. As a rule of thumb, tapered stems are adequate when femoral anteversion is  <  25°; conical stems should be adopted for higher anteversions.Level of evidenceIV.
