Dynamic bone fracture plates

A bone plate assembly comprising:

• a female plate portion having:
• a post upstanding from the female plate portion;
• a first end;
• a second end defining two apertures for fasteners;
• and an arm extending from the first end parallel to the female plate portion, the arm defining a plurality of ratchet teeth;
• a male plate portion having:
• two posts upstanding from the male plate portion;
• a first end for coupling to the first end of the female plate portion so that the plate portions only move linearly with respect to each other and a slot for receiving the arm;
• a second end defining two apertures for fasteners;
• and a pawl for engaging the ratchet teeth;
• a spring for dynamically connecting the plate portions by applying a compressive load therebetween, the spring having:
• an apex portion defining a hole for coupling to the post of the female plate portion;
• and a pair of elongated ears extending from the apex portion, each ear defining a slot for coupling to the posts of the male plate portion, respectively;
• and
• a modular wedge member dimensioned and configured to operatively engage an outer profile of at least one of the plate portions,
• wherein the first end of the male plate inserts in the first end of the female plate so that the arm extends into the slot of the male plate portion and the ratchet teeth are engaged by the pawl to retain the plate portions together, and the spring mounts on the posts of the plate portions such that the spring biases the male and female plate portions together.
