A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate.

Interbody spinal implants comprise internal sidewalls having a roughened surface topography. The internal sidewalls may be those that surround a substantially hollow implant center, including the sidewalls of a vertical aperture and sidewalls of a transverse aperture. The roughened surface topography comprises macro, micro, and nano features that comprise an amplitude, a peak to valley height, and spacing.

An intervertebral scaffolding system is provided having a rigid central beam and a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state.

A device for the repair of a phalangeal joint comprises a first anchor, a second anchor, and a flexible spacer connecting the first and second anchors. The flexible spacer comprises a plurality of elongate fibers extending axially or criss-crossed between the first and second anchors and a polymeric matrix interspersed with the plurality of elongate fibers. Specifically, a prosthetic metatarsophalangeal joint device comprises a porous metallic metatarsal bone anchor, a porous metallic phalangeal bone anchor, and a polymeric spacer element comprising parallel or criss-crossed elongate fibers that can connect the metatarsal bone anchor and the phalangeal bone anchor. Methods for manufacturing prosthetic joint devices comprise using three-dimensional printing processes or molding processes. Methods for implanting prosthetic joint devices comprise positioning porous metallic anchor components adjacent resected bones at planar interfaces and between which a polymeric spacer having axial aligned elongate fibers embedded in a matrix can be disposed.

A composite material for use, for example, as an orthopedic implant, that includes a porous reinforced composite scaffold that includes a polymer, reinforcement particles distributed throughout the polymer, and a substantially continuously interconnected plurality of pores that are distributed throughout the polymer, each of the pores in the plurality of pores defined by voids interconnected by struts, each pore void having a size within a range from about 10 to 500 μm. The porous reinforced composite scaffold has a scaffold volume that includes a material volume defined by the polymer and the reinforcement particles, and a pore volume defined by the plurality of pores. The reinforcement particles are both embedded within the polymer and exposed on the struts within the pore voids. The polymer may be a polyaryletherketone polymer and the reinforcement particles may be anisometric calcium phosphate particles.

A fusion cage has a first component that defines an outside surface that is configured to engage a vertebral endplate, and an interior surface. The fusion cage has a second component that defines first and second opposed surfaces. One of the first and second opposed surfaces can mate with the interior surface of the first component. The fusion cage can include vertical and lateral throughholes adapted to enhance fusion.

A system and method for further improving upon an ability of a surgeon to reduce or eliminate impaction forces when installing or assembling a prosthesis. An implant includes a surface treatment for aiding operations with the implant. For example, some surface treatments provide an asymmetry in installation versus removal to bias the associated implant deeper into an installation site.

A resorbable scaffold for partial meniscus regeneration. The resorbable scaffold includes a polymer filament network and a matrix in the polymer filament network. The polymer filament network includes alternating layers of circumferentially-oriented filaments and radially-oriented filaments, and has a three-dimensional shape and geometry which is substantially the same as a three-dimensional shape and geometry of the resorbable scaffold.

The present invention relates to pliable, compression-resistant bone-based products and methods of making the same.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.
