Patent ID: 8057476

Claim:
A humeral nail for the proximal humerus having first and second ends comprising a solid shaft having a proximal nail portion adjacent the first nail end and a distal nail portion adjacent the second end of the nail, the proximal nail portion having a longitudinal axis and at least three axially spaced completely threaded transverse bores, a bone screw having an end with a head and a threaded shaft received in each threaded bore each bore having an axis, which axes are circumferentially angularly offset from each other about the longitudinal axis of the proximal nail portion, at least two of the proximal transverse bores having a bore axis which extends at a non-perpendicular proximal-distal angle to the longitudinal axis of the proximal nail portion and at least one bore axis extends perpendicularly to the longitudinal axis of the proximal nail portion, a bore axis of a proximal bore of the non-perpendicular bores angled toward the first end and a bore axis of a distal bore of the non-perpendicular bores angled toward the second end, the bore axes of the first and second non-perpendicular bores lying in non-parallel planes the threaded shaft of the bone screw in the proximal bore angled towards a humeral head in a proximal to distal direction and the threaded shaft of the bone screw in the distal bore angled toward the humeral head in a distal to proximal direction.
