Abstract: Surgical kits for implanting a femoral fastener in a femoral bone may include the femoral fastener and at least one of: a targeting guide assembly, an anti-rotation assembly, and a plurality of tap tools. The targeting guide assembly may include a targeting guide base having a locating slot and a removal slot that are formed therethrough. The removal slot may extend from an inferior end of the targeting guide base into the locating slot. A guide pin may be placed through the locating slot and into the neck and head of the femoral bone to guide placement of the femoral fastener therein. The targeting guide base may be movable in a superior direction to release the guide pin inferiorly through the removal slot that extends from the locating slot to the inferior end of the targeting guide base.

Abstract: A femoral fixation device may include a shaft and a helical thread disposed about the shaft between a first location and a second location along the shaft. The helical thread may include a concave undercut surface. The femoral fixation device may be configured such that, when the femoral fixation device is implanted within a neck and a head of a femoral bone: the first location, the second location, and the helical thread therebetween may be disposed within the head of the femoral bone; the concave undercut surface may be oriented toward a proximal end of the femoral fixation device; and the concave undercut surface may be configured to transmit at least one force from the head of the femoral bone to the neck of the femoral bone.
