Bone plate with bladed portion

A bone plate for fixation of a fractured bone, the bone plate comprising:

• an elongated plate portion having a first longitudinal axis, an upper surface and a lower surface;
• a blade portion configured to be inserted into the interior of the fractured bone, the blade portion having a second longitudinal axis, an upper surface and a lower surface, the blade portion being angled with respect to the plate portion so as to define an included angle therebetween and the upper surface of the blade portion including a plurality of longitudinal channels;
• the plate portion having at least one hole for receiving a bone anchor having a shaft, the hole having
• a first portion defining a first central axis substantially perpendicular to the lower surface at the at least one hole;
• and
• a second portion overlapping and in communication with the first portion from the upper surface to the lower surface and defining a second central axis angled with respect to the blade portion, the second hole portion having a periphery, at least a portion of the periphery being threaded,
• wherein the second hole portion is configured to threadably receive the bone anchor such that the shaft is substantially coaxially aligned with the second central axis, threadably and angularly fixed in a single, predetermined position with respect to the blade portion and non-perpendicular to the lower surface of the plate portion at the at least one hole.

A bone plate system comprising:

• at least one bone anchor having a shaft and a head portion;
• a bone plate having an elongated plate portion having a first longitudinal axis, an upper surface and a lower surface and a blade portion having a second longitudinal axis, an upper surface and a lower surface, the blade portion configured to be inserted into the interior of the fractured bone and being angled with respect to the plate portion so as to define an included angle therebetween ranging between about 75° and about 110°;
• the plate portion having at least one hole, the hole having
• a first portion defining a first central axis and including a first counterbore along the upper surface, the first hole portion being configured to receive the bone anchor such that the head is capable of sliding engagement with the first counterbore;
• and
• a second hole portion in communication with the first hole portion from the upper surface to the lower surface and defining a second central axis angled with respect to the blade portion and non-perpendicular with respect to the elongated plate portion at the at least one hole, the second hole portion including a second counterbore that is at least partially threaded,
• wherein the second hole portion is configured to receive the bone anchor in a single, predetermined angular position such that the shaft is substantially coaxially aligned with the second central axis and the head portion is fixedly engaged with the second counterbore.

• at least one hole in the plate portion for receiving a bone anchor having a shaft, the hole having
• a first hole portion defining a first central axis substantially perpendicular to the lower surface at the at least one hole, the first hole portion being configured to receive the bone anchor;
• and
• a second hole portion overlapping and in communication with the first hole portion from upper to lower surface and defining a second central axis angled with respect to the first central axis, at least a portion of the second hole portion being threaded,
• wherein the second hole portion is configured to receive the bone anchor in a single, predetermined angular position such that the shaft of the bone anchor is substantially coaxial with the second central axis and non-perpendicular to the lower surface of the plate portion at the at least one hole.
