Method and device for attaching a bone plate
A method and device for attaching a bone plate to a bone includes the steps of placing a first surface of a wire insertion device against the bone, inserting a reference wire through an opening of the wire insertion device extending therethrough from the first surface of the wire insertion device to a second surface of the wire insertion device, removing the wire insertion device from the reference wire and positioning a bone plate on the bone by moving the bone plate in a transverse direction relative to a longitudinal axis of the reference wire so that the reference wire is received within a slot of the bone plate, the bone plate including a first surface facing toward the bone and a second surface opposing the first surface, the slot open to a lateral side surface connecting edges of the first and second surfaces.
1. A wire insertion device, comprising:
a base having a first surface shaped to correspond to a portion of bone against which the base is to be placed and a second surface opposing the first surface;
an opening extending through the base from the first surface to the second surface, the opening being configured to receive a reference wire therethrough along a desired path on which the reference wire is to be inserted into the bone, wherein an inner diameter of the opening corresponds to an outer diameter of the reference wire to guide the reference wire therethrough along a desired path; and
a leg extending away from the second surface of the base.
2. The wire insertion device of claim 1 , wherein the leg includes a handle coupling at an end thereof for coupling a hand grip to the wire insertion device.
3. The wire insertion device of claim 1 , wherein the first surface includes at least one mandrel protruding therefrom.
4. The wire insertion device according to claim 3 , wherein the at least one mandrel is a protrusion including a sharp tip for engaging the surface of a bone.
5. The wire insertion device of claim 1 , wherein a shape of the first surface corresponds to the shape of a portion of the proximal femur against which the wire insertion device is to be placed.
6. The wire insertion device of claim 1 , wherein the opening is chamfered at an end facing the second surface.
7. The wire insertion device of claim 1 , wherein an inner diameter of the opening is between 2 and 15 mm.
8. The wire insertion device of claim 1 , wherein the length of the opening is between 5 and 50 mm.
