An interbody fusion implant with deployable bone anchors includes a support member, a monolithic body that accommodates the support member, and a longitudinal hole along a vertical length of the support member. The support member includes a first end and a second end. The second end includes two flanges. The flanges are configured to dig into an endplate of a vertebral body. The flanges of the support member provide a location fixation on an implantation of the interbody fusion implant into the vertebral body. The support member may also include at least one of a clip shaped support member and an I-shaped support member. The I-shaped support member may allow a rigidity and a support in flexion-extension through a living-hinge positioned in a middle of the I-shaped support member. The longitudinal hole sustains loads imported on the interbody fusion implant and allows the interbody fusion implant to flex freely.
