Spinal fixation device

A spinal fixation device comprising:

• a housing defining an aperture;
• an end plate assembly operatively coupled with the housing, a portion of the end plate assembly pivotable about a pivot pin defining a longitudinal axis, at least a portion of the end plate assembly slidably received within the housing;
• and
• first and second rotatable members operatively coupled with the end plate assembly such that rotation of the first and second rotatable members transitions the spinal fixation device between an expanded state and a contracted state, wherein the first and second rotatable members are configured to engage a first instrument to transition the spinal fixation device between the expanded state and the contracted state, wherein one of the first or second rotatable members is configured to engage a second instrument to adjust an angular orientation of the portion of the end plate assembly.

An adjustable spinal implant comprising:

• a housing positionable between adjacent vertebrae;
• a proximal region of the adjustable spinal implant having a first height;
• a distal region of the adjustable spinal implant having a second height;
• and
• an end plate assembly coupled with the housing, the end plate assembly including an end plate configured to engage a vertebral body, and first and second elongate members pivotably secured to the end plate about respective pins such that axial movement of the first and second elongate members in tandem adjusts the first height and the second height, and relative movement between the first and second elongate members adjusts one of the first height or the second height such that the proximal region is adjustable independently of the distal region, the housing attachable to a first instrument having a first rotatable member rotatable to cause axial movement of the first and second elongate members in tandem, the housing attachable to a second instrument having a second rotatable member rotatable to cause relative movement between the first and second elongate members.
