Abstract

An expandable intervertebral implant (20) including a body (22) having a longitudinal axis (L) and including first and second axial walls (30, 32) spaced apart along a transverse axis (T), and first and second transverse end walls (34, 36) extending between and interconnecting the first and second axial walls (30, 32). The intervertebral implant (20) includes an expansion member (24) co-acting with the axial walls (30, 32) to expand the body (22) along the transverse axis (T).
