1. An expandable implant, comprising:
an upper main support configured to engage a first portion of bone;
a lower main support coupled to the upper main support and configured to engage a second portion of bone, wherein the upper main support is adjustable relative to the lower main support to adjust a height of the expandable implant;
an upper pivoting support configured to engage the first portion of bone, wherein the upper pivoting support is rotatably movable relative to the upper main support;
a lower pivoting support coupled to the upper pivoting support and configured to engage the second portion of bone, wherein adjustment of the upper main support relative to the lower main support causes a corresponding adjustment of the upper pivoting support relative to the lower pivoting support, and wherein the lower pivoting support is rotatably movable relative to the lower main support;
at least one alignment guide provided on one of the lower main support and the upper main support; and
at least one alignment recess provided on the other of the lower main support and the upper main support and configured to receive the at least one alignment guide to maintain a desired alignment between the upper main support and the lower main support;
wherein the at least one alignment guide and the at least one alignment recess limit the upper and lower main supports to linear relative motion;
wherein the upper pivoting support is movable between a first position, where a first portion of the upper pivoting support is aligned with a longitudinal axis of the upper main support and a second portion of the upper pivoting support is adjacent a first side of the upper main support, and a second position, where the first portion of the upper pivoting support extends beyond a second side of the upper main support opposite the first side and in a first direction, and the second portion of the upper pivoting support extends beyond the first side of the upper main support in a second direction opposite the first direction.
