Internal osteotomy fixation device

An internal osteotomy fixation device, comprising:

• a distal plate including a channel;
• a slide slidably received within the channel such that the slide is translatable with respect to the distal plate along a first axis, the slide having ratchet teeth on a first surface;
• a ratchet arm fixed to the distal plate, the ratchet arm including teeth configured to engage the slide ratchet teeth;
• and
• a proximal plate;
• wherein
• the proximal plate includes a first portion defining a first plane, and a ledge defining a second plane substantially perpendicular to the first plane.

An internal osteotomy fixation device, comprising:

• a distal plate including a channel;
• a slide slidably received within the channel such that the slide is translatable with respect to the distal plate along a first axis, the slide having a segment of ratchet teeth on a first surface, the segment having a first length;
• and
• a ratchet arm fixed to the distal plate, the ratchet arm including teeth configured to engage the slide ratchet teeth, the ratchet arm having a second length;
• wherein
• in a completely retracted configuration, the segment overlaps the ratchet arm such that an overall length of the device is dependent upon the longer of the first length or the second length.
