US Patent 7981142 Bone plate and screw system allowing bi-directional assembly

Bone screws and bone plates are provided that offer the surgeon the ability to either assemble the screws to the plate, or the plate to the screws, depending on the surgeon's preference and the patient's circumstances. The bone screws and bone plates of the present invention include a combination of geometric configurations that allow the screws and plates to fit together from different assembly directions. Additionally, the bone screws and bone plates can include material resilience features to allow expansion/contraction during assembly to allow bi-directional attachment to one another.
