Drill guide for orthopedic device
A bone plate system for use with fasteners for fixation of a fractured bone, including a bone plate having an elongate shaft for placement against the bone. The bone plate further has at least one threaded hole for receiving at least one fastener, with each hole having a central axis. The plate further has a bone contacting first surface, an opposite second surface, a thickness extending in a dimension between said first and second surfaces; and at least one tubular drill guide cap. The drill guide cap is engageable with a first hole of at least one threaded hole, the cap having a threaded exterior, an internal bore, a proximal end, and a distal end.
1. A bone plate system for fixation of a fractured bone, the system comprising:
a bone plate comprising:
an elongate plate body extending from a proximal end to a distal end and including a bone contacting first surface and an opposite generally planar second surface;
a first fastener aperture extending through the first and second surfaces of the plate body;
a second fastener aperture extending through the first and second surfaces of the plate body;
a first leg member formed integral with the distal end of the plate body and extending away from the first surface of the plate body, the first leg member including fixation projections configured for engagement with bone; and
a second leg member formed integral with the distal end of the plate body and extending away from the first surface of the plate body, the second leg member including fixation projections configured for engagement with bone; and
a plurality of fasteners, each fastener configured for insertion within at least one of the first fastener aperture or the second fastener aperture;
wherein the plate body extends along a longitudinal plate body axis from the proximal end to the distal end of the plate body, the plate body further including a first side extending between the first and second surfaces of the plate body and an opposite second side extending between the first and second surfaces of the plate body;
wherein the first and second fastener apertures are aligned along the longitudinal plate body axis;
wherein the first and second leg members extend away from the longitudinal plate body axis the first and second leg members extending from the bone contacting first surface;
wherein the plate body defines a first plate width at a location between the first and second fastener apertures and larger second and third plate widths at locations corresponding to the first and second fastener apertures, respectively; and
wherein a plate width is defined at the distal end of the plate body where the first and second leg members extend away from the first surface of the plate body, the plate body gradually increasing in width from the third plate width at the second fastener aperture to the plate width at the distal end of the plate body.
2. The bone plate system of claim 1 , wherein the fixation projections comprise serrations.
3. The bone plate system of claim 1 , wherein the fixation projections comprise teeth.
4. The bone plate system of claim 1 , wherein each of the plurality of fasteners comprises a head portion and a shaft portion, the shaft portion defining a shaft length.
5. The bone plate system of claim 4 , wherein the shaft length of at least one of the plurality of fasteners is different from the shaft length of at least one of the other plurality of fasteners.
6. A bone plate for fixation of a fractured bone, comprising:
an elongate plate body extending along a longitudinal plate body axis from a proximal end to a distal end, the plate body including a bone contacting first surface and an opposite second surface, the plate body defining a generally flat shape along the longitudinal plate body axis from the proximal end to the distal end;
a first fastener aperture extending through the first and second surfaces of the plate body;
a second fastener aperture extending through the first and second surfaces of the plate body;
a first leg member extending from the distal end of the plate body and formed integral therewith; and
a second leg member extending from the distal end of the plate body and formed integral therewith;
wherein the first and second leg members extend away from the longitudinal plate body axis the first and second leg members extending from the bone contacting first surface;
wherein the plate body further includes a first side extending between the first and second surfaces of the plate body and an opposite second side extending between the first and second surfaces of the plate body;
wherein the first and second fastener apertures are aligned along the longitudinal plate body axis;
wherein the plate body defines a first plate width at a location between the first and second fastener apertures and larger second and third plate widths at locations corresponding to the first and second fastener apertures, respectively; and
wherein a plate width is defined at the distal end of the plate body, the first and second sides of the plate body diverging away from the longitudinal plate body axis from the third plate width at the second fastener aperture to the plate width at the distal end of the plate body.
7. The bone plate of claim 6 , wherein the first and second leg members each include a plurality of fixation elements.
8. The bone plate of claim 6 , wherein the first and second leg members are substantially cylindrical.
9. The bone plate of claim 6 , wherein the first leg member extends from the distal end of the plate body at a location adjacent to the first side, and wherein the second leg member extends from the distal end of the plate body at a location adjacent to the second side.
