Observational analysis reveals alignment and technical parameters impact initial stability in femoral arthroplasty, suggesting surgery optimization may reduce subsidence.
Early subsidence of cementless stems in femoral neck fractures is driven primarily by modifiable surgical factors. Achieving neutral alignment and adequate metaphyseal fill markedly reduces early migration, while the impact of demographic and bone-quality variables is limited. Optimizing these technical parameters may enhance initial stability in cementless arthroplasty.
