A surgical implant device, including: an implant body; a porous layer disposed adjacent to the implant body, wherein the porous layer includes a lattice of intersecting struts; and a plurality of needle structures protruding from the porous layer opposite the implant body, wherein at least some of the plurality of needle structures traverse the porous layer and are anchored to the implant body. The plurality of needle structures that traverse the porous layer and are anchored to the implant body are coupled to one or more intersecting struts of the lattice. Optionally, some of the plurality of needle structures are spaced apart from the implant body and are anchored only to the porous layer. Preferably, one or more of the implant body, the porous layer, and the plurality of needle structures are formed by an additive manufacturing technique.

Surgical implant devices incorporating porous surfaces and associated method of manufacture

A surgical implant device, comprising: a body portion; and one or more surfaces comprising a plurality of protruding structures; wherein the body portion and the one or more surfaces comprising the plurality of protruding structures are integrally formed. The one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process. The plurality of protruding structures comprise a plurality of needles. Optionally, the surgical implant device comprises one of an anterior lumbar interbody fusion cage, a posterior lumbar interbody fusion cage, a transforaminal lumbar interbody fusion cage, an oblique lumbar interbody fusion cage, a cervical cage, and a bone screw.

Surgical implant devices incorporating porous surfaces

A surgical implant device, comprising: a body portion defining a plurality of ports; a plurality of bone screws disposed partially through the plurality of ports defined by the body portion; a locking plate disposed over a head portion of at least one of the plurality of bone screws and engaging a plurality of recesses manufactured into a side of the body portion; and a screw operable for compressing the locking plate against the side of the body portion. Optionally, the surgical implant device further comprising: one or more surfaces comprising a plurality of protruding structures; wherein the body portion and the one or more surfaces comprising the plurality of protruding structures are integrally formed. The one or more surfaces comprising the plurality of protruding structures are formed by an additive manufacturing process.

Surgical implant devices incorporating porous surfaces and a locking plate

A surgical plate device that incorporates a screw locking mechanism in each screw hole by which the surgical plate device is affixed to a bony segment. The screw locking mechanism includes a tab structure emanating from an interior portion (or either surface) of the surgical plate that is biased into a portion of the corresponding screw hole. When a screw is inserted into the screw hole, the head of the screw temporarily biases the tab structure out of the screw hole, until the head of the screw passes below the plane of the tab structure, at which point the tab structure rebounds into the previously occupied portion of the screw hole, thereby covering a portion of the head of the screw and preventing it from 'backing out.'
