“…Laumonerie et al conducted a survey of prostheses implanted via cemented fixation and found a relatively high rate of painful loosening (approximately 21.5%), osteolysis (53.8%), and overstuffing (46.2%) ( Laumonerie et al, 2018 ). Szmit et al performed a biomechanical study and found that using cemented fixation would make the radial head prostheses less effective in distributing high contact stress and easier to get abraded ( Szmit et al, 2019 ). Although Kachooei et al observed the lowest rate of revision with cemented fixation in their systematic review and meta-analysis, they thought that the rate may be related to difficulties in removing the implant design ( Kachooei et al, 2018 ).…”

“…The values of these loads and load locations were selected in accordance with previously published studies. A vertical downward force of 100 N was applied at the stress point 15,16 . It was coupled with the surface, while the distal radius was limited to six degrees of freedom.…”
