Webb1 juni 2024 · The PFNA-II group had a significantly higher degree of lateral sliding of the helical blade (P < 0.001). The InterTan group had a better Harris hip score, mobility score, Timed Up and Go test scores, and abductor strength (P < 0.05) at 1 year. The incidence of varus collapse and medial blade migration were higher in the PFNA-II group (P > 0.05).
