Abstract: A composite interbody device includes superior and inferior endplates with a plastic core molded therebetween. The core includes one or more features for permitting bone growth through the core. Each endplate includes a bone interface side coated with hydroxyapatite, for promoting bone on-growth. Pores in the bone interface sides permit bone in-growth. Core interface sides of the endplates include relatively larger pores for accepting molten material from the core, for example during injection molding, to enhance bonding of the endplates with the core. Each endplate has a central barrier layer for preventing the molten core material from extruding through the core interface pores into the bone interface pores, reserving the bone interface pores for bone in-growth. A method of manufacturing the composite interbody device is also disclosed.
