A torsion locking interface for an orthopaedic implant taper interlock includes a proximal segment with a frustopyramidal boss having four flat faces and a distal segment with a receiver. Opposing set screws engage the flat faces obliquely in a plane orthogonal to a rotational axis, providing torsional resistance in both rotational directions. This prevents unintended rotational displacement that could compromise the taper interlock due to bodily fluids reducing friction. The receiver may define a cylindrical interior for controlled rotation before fixation, and the frustopyramidal boss may have radiused edges to reduce stress concentrations and improve adjustability. In one embodiment, the set screws engage opposite faces, while in another, they engage adjacent orthogonal faces, each configuration optimising torsional resistance. The interface is particularly suited for modular knee and hip implants, maintaining internal or external rotational stability to reduce the risk of taper slippage and implant misalignment.
