Abstract: A modular lateral expansion device to be inserted into an intervertebral space. The modular lateral expansion device includes a first member and a second member. The first end and the second end comprise a first extension and a second extension respectively. The first extension and second extension outwardly protrude from the first member in a same direction and are positioned at an axis transverse to a longitudinal axis of the first member. The second member comprises a first end and a second end. The first end comprises a plurality of outwardly extended arms and a first passage positioned between the plurality of outwardly extended arms. The first end of the second member is dimensioned and configured to couple to the first end of the first member. The second end comprises a second passage dimensioned and configured to accommodate the second extension of the first member.

Abstract: A modular lateral expansion device to be inserted into a vertebral body. The modular lateral expansion device comprises a pair of complementary lateral members. Each of the lateral members includes a first end, a second end, a first lateral portion, a second lateral portion, a top wall, a bottom wall, and a cavity configured through the top wall and the bottom wall. The top wall includes a top ridge and a top contour surface and the bottom wall includes a bottom ridge and a bottom contour surface. The top ridge and the bottom ridge are inwardly angled into the second lateral portion. The first lateral portion includes a plurality of cuts. The second lateral portion includes a first slot positioned at an edge of the second lateral portion and a second slot positioned in a substantially central area of the second lateral portion.
