Abstract
An apparatus supports the spine between vertebrae and promotes spinal fusion. The apparatus generally includes a first supporting member, a second support member, and an expansion member. The first support member has a first longitudinal passage extending there through and a first supporting end configured to engage tissue. The second supporting member contains a second longitudinal passage extending there through and a second supporting end configured to engage tissue. The second longitudinal passage is dimensioned to receive at least a portion of the first supporting member. The first and second supporting members are configured to move with respect to each other. The expansion member is removably positioned between the first and second supporting members and is adapted to maintain the first and second supporting members in a fixed relative position.
