Abstract
A bone fixation system including a bone fixation element including a head portion having a bore passing therethrough from a first side surface to a second side surface, wherein the bore is perpendicular to a longitudinal axis of the bone fixation element, a securing element positioned within the bore, and a bone plate extending along a plate axis and having a threaded plate hole extending therethrough from a first surface to a second surface configured to contact a bone in an operative configuration.
Claims28
A bone fixation element comprising:
- a shaft extending along a longitudinal axis of the bone fixation element from a proximal portion to a distal portion;
- and
- a head portion comprising a first side surface and a second side surface opposite the first side surface, wherein the first side surface and the second side surface are shaped to allow for variable angle rotation of the bone fixation element;
- and
- a bore passing through from the first side surface to the second side surface, wherein the bore is perpendicular to the longitudinal axis of the bone fixation element;
- and
- a securing element positioned within the bore, wherein the securing element is configured to meet an interior surface of a bone plate hole without penetrating the interior surface of the bone plate hole.
A bone fixation system comprising:
- a bone fixation element comprising:
- a shaft extending along a longitudinal axis of the bone fixation element from a proximal end to a distal end;
- and
- a head portion comprising:
- a first side surface and a second side surface opposite the first side surface, wherein the first side surface and the second side surface are shaped to allow for variable angle rotation of the bone fixation element;
- and
- a bore passing through from the first side surface to the second side surface, wherein the bore is perpendicular to a longitudinal axis of the bone fixation element;
- a securing element positioned within the bore;
- and
- a hollow cylindrical nut configured to fix the bone fixation element to a bone fixation device:
- wherein the bore and securing element are configured to allow for joint-like rotation of the bone fixation element.
