Claim:
1. An orthopedic nail of generally rod-like shape having a through hole in a proximal part of said orthopedic nail extending from a first, lateral side to a second, medial side of said orthopedic nail, wherein a lateral end of said through hole is located closer to a distal end of said orthopedic nail than a medial end of said through hole, and being adapted to receive a screw and/or a pin, a first end of said through hole at said first, lateral side defining a rim region, wherein at least one surface notch is provided in said rim region at and restricted to an outer circumferential surface of said orthopaedic nail, said surface notch being arranged transverse to a nail axis of said orthopedic nail, a width (W) of said surface notch in the direction of said nail axis being smaller than a diameter of said through hole, the width being measured in the axial direction of the nail between a proximal most point and a distal most point of said surface notch, wherein a length of said surface notch is longer than said diameter of said through hole, wherein said surface notch is suited to interrupt tensile stress lines in said rim region induced by a force (F L ) acting on a support point for said screw and/or pin at said first side in a proximal region of said first end of said through hole.
