Bone Plate Anti-Torque Plug for Rotationally Stable Fixation

The patent combines multiple functions into a single integrated implant device that simultaneously provides compression (via the clip), rotational stability (via the anti-torque plug with non-circular cross-section), and structural support (via the bone plate). This merging of functions resolves the contradiction by achieving enhanced rotational stability without proportionally increasing device complexity, as the anti-torque feature is integrated into the existing implant structure rather than added as a separate component.

The patent employs asymmetric geometry in the anti-torque plug by giving it a non-circular cross-section (such as rectangular, triangular, or oval). This asymmetric shape prevents rotation of the plug within the bone fragment, thereby providing rotational stability. The asymmetric design directly addresses the rotational stability requirement while maintaining reasonable device complexity through geometric modification rather than complex mechanical structures.

The anti-torque plug incorporates a non-circular cross-section that asymmetrically engages with the bone fragment, creating mechanical interlocking that resists rotational forces. This asymmetric geometry works in conjunction with the compression force to provide reliable fixation, preventing the plug from rotating while maintaining the compressive load across the bone fragment interface.

The patent implements counter-torque features that oppose and balance rotational forces acting on the bone fragments. The anti-torque plug generates counteracting moments that neutralize the destabilizing rotational effects, working in conjunction with the compression force to achieve stable and reliable fixation during the healing process.
