Fixation Of Femoral Neck Fractures
First Claim

1. A method comprising:
- coupling a femur to a base plate having a proximal end portion that includes first, second, and third holes, the first hole (a) distal and anterior to the second hole, and (b) distal and posterior to the third hole;
positioning a first screw across a femoral neck fracture of the femur and nproximate to the femoral neck inferior cortex so that the inferior cortex supports the first screw upon loading;
positioning second and third screws across the fracture; and
coupling first, second, and third conduits to the first, second, and third screws and first, second, and third holes.

Abstract
In one embodiment of the invention, a device for femoral neck fracture fixation includes a base, a first conduit that slidably receives a first screw, a second conduit that slidably receives a second screw, and a third conduit that slidably receives a third screw. The first conduit is spaced from the second conduit to allow the first screw to couple to the femoral neck inferior cortex and to further allow the second screw and third screw to each couple to the femoral head and reduce angular instability of the femoral neck fracture.

16. A method comprising:
-
coupling a femur to a base plate including first and second holes; positioning (a) a first screw across a femoral neck fracture of the femur and proximate to the femoral neck cortex, and (b) a second screw across the fracture; coupling first and second conduits to the first and second screws and first and second holes; and applying a loading force to the fracture; wherein the force is countered based on the proximity of the first screw to the femoral neck cortex. - View Dependent Claims (17, 18, 19, 20)
