Abstract: The longitudinal implant is fastened to bones on either side of a damaged area through a connecting device. Said implant is comprised of a filament or fiber composite material and said connecting device is made of a material harder than said longitudinal implant. The longitudinal implant is preferably made of a carbon filament composite material, wherein the filament are encapsulated in a polymer matrix.

Abstract: Repair of a spine from a posterior approach especially for locating an implant between a lower and upper human vertebra includes making an incision in the skin lateral to the midline, making an incision through the Erector Spinae Aponeurosis (ESA) following the ELIF groove, separating the ESA from the Longissimus Thoracis Pars Lumborum (LTPL), atraumatic separating the Multifidus from the LTPL using the interfascial boundary between the Multifidus and the LTPL, and creating a surgical plane having an angle of 20°-60°.

Abstract: The cylindrical fiber reinforced implant is designed to be inserted between two adjacent vertebrae. The implant having an outer wall with a general cylindrical or oval shape and preferably an open volume for bone filling. Said wall having reinforcing fibers which at least in part are oriented in a first direction. A support extending within said volume having reinforcing fibers which are at least in part oriented in a second direction, said first and said second directions are different. Preferably the fibers of the outer wall are at least partly concentrically oriented. The support is preferably a separately formed part, that is inserted into the outer wall.

Abstract: The medical implant is constructed of a fiber reinforced plastic. That fibers (50a, 50b) are generally aligned in layers (C, D, E), wherein the fibers of at least two different layers having different orientations. The fibers are long and oriented in relationship to the biomechanical requirements. The implant can oppose multi-directional forces and can be manufactured with the appropriate strength and stiffness.

Abstract: A fusion implant apparatus, in for the replacement of a vertebra or an intervertebral disc, having at least one biocompatible structure. The structure is made of a composite material having reinforcing fibers, and has a first and second face to engage adjacent bone structures to be fused, struts extending between the first and second faces, and a hollow interior space for reception of bone growth inducing substances. The fibers are long fibers and the majority of these long fibers have a direction that follows the longitudinal forces upon the first and second faces, which is the direction of trabecular structures of the adjacent bone structure, so that a majority of long fibers are essentially an extension of these trabecular structures.

Abstract: The pair of lumbar interbody implants is designed to be pushed laterally in a space between adjacent vertebrae for replacing the disc between these vertebrae. Each implant comprises a first and a second saggital wall and an anterior wall at one end and a posterior wall at the other end. The two implants are asymmetric to each other and are therefore more appropriate for the transforaminal lumbar interbody fusion. Preferably a first implant has a first saggital wall with an outer surface that is curved and a second saggital wall that is essentially plane.
