Zusammenfassung:	A spine implant for an ALIF procedure includes anchoring members being either a bone screw or flexible barb, each having a head on one end of a shaft, and a tip on another end of the shaft. The spine implant includes a porous cage having a front, rear, central cavity, and three angled bores in the front that extend into the central cavity configured to receive one of the plurality of anchoring members such that the tip of the anchoring member extends from one or another side of the cavity with its head retained in the front. The spine implant further includes two retention members configured for insertion into the front such that a portion of the two retention members are positioned over the heads of two, adjacent anchoring members to inhibit bone anchor backout via cam action between the retention member and the heads of the anchoring members.
