An intervertebral implant for fusing vertebrae is disclosed. The implant may have a body with curved, posterior and anterior faces separated by two narrow implant ends, superior and inferior faces having a plurality of undulating surfaces for contacting vertebral endplates, and at least one depression in the anterior or posterior face for engagement by an insertion tool. The implant may also have one or more vertical through-channels extending through the implant from the superior face to the inferior face, a chamfer on the superior and inferior surfaces at one of the narrow implant ends, and/or a beveled edge along a perimeter of the superior and inferior faces. The implant configuration facilitates transforaminal insertion of the implant into a symmetric position about the midline of the spine so that a single implant provides balanced support to the spinal column. The implant may be formed of a plurality of interconnecting bodies assembled to form a single unit. An implantation kit and method are also disclosed.

The present disclosure includes implant systems, devices, and implants. The interbody spacers including a first endplate, a second endplate, and a coupling member coupled to and extending between the first endplate and the second endplate. Methods of using the interbody spacers are also disclosed.

In various embodiments, an implant for interfacing with a bone structure includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue. In some embodiments, a method is provided that includes accessing an intersomatic space and inserting an implant into the intersomatic space. The implant includes a web structure including a space truss. The space truss includes two or more planar truss units having a plurality of struts joined at nodes and the web structure is configured to interface with human bone tissue.

Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.

An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.

An artificial intervertebral disc is configured to be inserted between adjacent human vertebrae. The artificial intervertebral disc includes a first connection block, a joint block and a second connection block. The joint block has a convex surface and a rear surface. The rear surface of the joint block is stacked on the first connection block. The second connection block is slidably stacked on the convex surface of the joint block, such that the second connection block is movable relative to the first connection block. In addition, the convex surface is a curved surface, and the convex surface is arranged off-axis with respect to the rear surface.

The present invention provides for an improved spinal implant which is useful in bone fixation surgeries. The spinal implant as described herein provides a surgeon with a device that can easily and safely be inserted into the space previously occupied by the spinal disc. The spinal implant contains one or more magnets positioned on or within the device to self-align with one or more additional spinal implants inserted therein for the purpose of preventing misalignment of a plurality of implant devices during surgical procedures and preventing implant expulsion.

The present invention comprises the provision and use of new and improved arthroscopic instrumentation for (i) harvesting a tissue biopsy from a non-critical section of a joint, and (ii) sizing and seating an autologous graft at an implant site.

The strength of bone implant attached to a bone is improved by using hybrid inserts which have stems and wings having bone ingrowth surface features and caps having outer surfaces of cured polymethyl methacrylate (PMMA). The stems and wings of the hybrid inserts are inserted into living bone and the bone implant is attached to the hybrid inserts with PMMA cement. Over time, the bone grows into the bone ingrowth surface features. The bone ingrowth strengthens the bonding of the hybrid inserts and the bone implant with the bone over time. The hybrid inserts increase the shear, tensile and torque strength of the bone implants. Bone inserts that do not have ingrowth surface features loosen over time.

A vertebral column implant assembly for insertion between two vertebrae, the assembly comprising: a superior implant body for engagement with a superior vertebra; an inferior implant body for engagement with an inferior vertebra; a central implant body adapted to be positioned in between the superior implant body and the inferior implant body, the central implant body further comprising: a first fastening arrangement positioned on an upper face of the central implant body to engage and fasten the superior implant body; and a second fastening arrangement positioned on a lower face of the central implant body to engage and fasten the inferior implant body; wherein each of the central implant body, the superior implant body and the inferior implant body comprises internal walls defining respective passages, such that the first and second fastening arrangements are positioned along inner marginal portions of the superior and inferior implant bodies respectively and structured to engage the central body with the superior and inferior implant bodies respectively to interconnect each of the respective passages to form a continuous passage to allow graft material to be positioned therein.
