An intervertebral implant for implantation in an intervertebral space between vertebrae. The implant includes a body extending from an upper surface to a lower surface. The body has a front end, a rear end and a pair of spaced apart first and second side walls extending between the front and rear walls such that an interior chamber is defined within the front and rear ends and the first and second walls. The body defines an outer perimeter and an inner perimeter extending about the internal chamber. At least one of the side walls is defined by a solid support structure and an integral porous structure, the porous structure extending from the outer perimeter to the inner perimeter. The porous structure embeds or encapsulates at least a portion of the solid support structure.

A variable lordotic interbody spacer including a face plate, superior and inferior endplates coupled to the face plate via a hinge, an actuation frame between the endplates, and an actuation screw. The face plate includes actuation and stabilizer channels. Each of the endplates has endplate arms coupled by an endplate base, and includes actuation ramp recesses. The actuation frame includes frame arms coupled by a frame base in a generally U-shaped configuration, each actuation frame arm having a stabilizer feature passing through a corresponding stabilizer channel and having actuation ramp pins fitted to a corresponding ramp recesses. The actuation screw passes through the actuation channel, with a head retained at the front surface and a threaded end coupled to the actuation frame. When operated, the actuation screw moves the actuation frame between the superior endplate and the inferior endplate to adjust an angle therebetween.

An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.

An intervertebral fusion cage for the fusion of two vertebral bodies of the vertebral column comprises a first portion and a second portion opposite the first, both having a planar conformation axially elongated along a central axis. The first and the second portion have respective contact surfaces for receiving, in abutment, a respective vertebral body. The cage can also comprise a gripping area for connection with a positioning device. The first and the second portion are hinged to each other along a hinge axis so as to be able to rotate relatively in relation to each other with a continuous movement.

A laterally deflectable asymmetric implant for implanting into a body may comprise a deflectable piece having distal and proximal ends and assuming a straightened insertion state. The backbone may abut or interconnect with said deflectable piece at the distal end of the deflectable piece. In a fully deflected state the implant may define an asymmetric shape, e.g. a D-shaped loop, defining an at least partially enclosed volume. The deflectable piece may comprise a sequence of segments interconnected at effective hinges. Longitudinal pressure applied to the proximal end of the deflectable piece (or applied to the backbone in an opposite direction) may cause relative longitudinal movement between the backbone and the proximal end of the deflectable piece and may generate outward horizontal movement of the deflectable piece away from the backbone. In one embodiment, the implant is implanted using lateral access into an anterior zone of a vertebra and deployed posteriorly.
