Patent ID: 8398690

Claim:
An osteosynthesis construct, comprising: a bone plate having two or more holes with locking threads for fixation of bone screws to the plate; and two or more bone screws for positive-locking engagement with the plate, at least one of said two or more bone screws comprising a shaft having a neck section, a mid section, and a threaded front end, at least one of said neck section and said mid section being rotationally asymmetric to impart to the bone screw a direction-dependent bending stiffness having a preferential direction of bending having a lower bending stiffness compared to a bending stiffness in a direction perpendicular to the preferential direction of bending; and a threaded head portion adjoining the shaft, said threaded head portion having threads to provide for a positive-locking engagement of the bone screw with the bone plate, wherein said threads of said threaded head portion are rotationally timed with said threads of said plate holes to provide for a positive locking engagement of the bone screw with the bone plate resulting in a predefined final orientation of the bone screw with respect to the plate to align the bone screw to exploit the preferential direction of bending.
