Three-dimensional analysis of the cortical contact state of short and conventional stems in different stem positions in total hip arthroplasty
Clinical Biomechanics(2021)
Abstract
•Short stems achieve the same cortical contact as conventional stems in any types of femoral canal.•The extended/flexed stem positions increase distal contact in conventional stems.•The distal contact may increase in patients with high femoral anteversion.
