Bump cut on hole edge

A bone fixation system, comprising:

• a device configured for insertion into a bone having an elongated body having a first channel extending distally therein to from a proximal end of the device along a longitudinal axis of the device and a second channel extending transverse to the longitudinal axis between first and second openings, the second channel extending along a channel axis and being dimensioned to permit insertion of an implant therethrough, and a first bump disposed on a periphery of the first opening at a location at which a stress concentration would be at a maximum if no such first bump were formed, the first bump being dimensioned to diffuse a concentration of stress about the periphery due to forces applied thereto by an implant extending through the second channel;
• a second bump on the periphery of the first opening, the second bump configured and dimensioned to distribute stresses around the first opening due to forces applied to the device via the implant, the second bump comprising first and second walls extending radially into the first opening away from the periphery of the second opening, the first and second walls joining one another at a second apex of the second bump, wherein the second bump is located opposite the first bump;
• and
• an implant configured for insertion through the second channel,
• wherein the first bump is defined by first and second milled portions disposed on first and second sides thereof, each of the first and second milled portions having a radius of curvature selected to diffuse the concentration of stress on the first apex and the first bump is formed between, and the first bump is formed by creation of the first and second milled potions.
