The effect of cup outer sizes on the contact mechanics and cement fixation of cemented total hip replacements
Highlights • Two cup designs with cup outer diameters of 40 and 43 mm were modelled. • The differences of peak stresses in the acetabular cup between the two cup designs were negligible. • The stresses of the cement mantle for cup design of 40 mm were higher than that of 43 mm. • The differences of...

Zusammenfassung: | Highlights • Two cup designs with cup outer diameters of 40 and 43 mm were modelled. • The differences of peak stresses in the acetabular cup between the two cup designs were negligible. • The stresses of the cement mantle for cup design of 40 mm were higher than that of 43 mm. • The differences of the stresses in the cement mantle between the two cup designs were compared to the clinical performance of the two cup designs. |
