The influence of “kickstand” screws on the mechanical performance of a lateral distal femoral plate: a finite element analysis

Bone & Joint Research
Aims: Lateral locked plating of distal femoral fractures is widely reported, yet there remains a 9% to 19% incidence of mechanical failure. Obliquely directed “kickstand screws”, from the metaphyseal portion of a plate toward far-sided articular ...
