Claim Text:
1. A method of dynamically compressing a fracture of a bone, comprising: a) providing a bone plate having an elongate shaft, the shaft defining, a first screw hole having a circular opening for receiving a bone screw therein so as to longitudinally fix said plate relative to the bone, a second screw hole having an elongate opening defining a first end and second end, and a screw ramp extending in a downward slope from said first end toward said second end and extending at least one half said length of said second screw hole, said screw ramp having an upper bevel surface and a lower sidewall, a flared recess opening to said upper surface and provided above said ramp adjacent said second end of said second screw hole, and a Longitudinally flared lower recess opening to said lower surface and provided beneath said first end and flaring in a direction opposite said upper recess; b) first driving a first bone screw into the first screw hole on a first side of the fracture to longitudinally fix the bone plate relative to the bone; c) second driving a second bone screw having a shaft and a head with a lower surface into the second screw hole on a second side of the fracture, the second bone screw located at the first end of the second screw hole and driven until the lower surface of the head enters into contact with the first end of the screw hole; and d) further driving the second bone screw to cause the ramp of the bone plate to displace under the head of the second bone screw and continuing to drive the second bone screw until the second bone screw contacts the second end of the second screw hole so as to draw the bone into compression across the fracture.
