Abstract: The present invention is directed to a surgical implant for the fusion of two adjacent vertebrae with an upper plane for contacting an upper vertebral body and a lower plane for contacting a lower vertebral body and a tubular structure, wherein the tubular structure is formed by a plurality of tubes running from the upper plane to the lower plane and in substantially horizontal direction throughout one side of the surgical implant straight to the opposite side of the surgical implant. This tubular structure has the advantage that the formation and ingrowth of new bone is promoted and advantaged and that the degree of formation and ingrowth of new bone is detectable by X-ray measurements.

Abstract: The present invention relates to a device for the stabilization of the spine comprising at least two pedicle screws and at least one interjacent linking member. The present invention further relates to pedicle screws which combine the advantages of a monoaxial screw with those of a polyaxial screw by avoiding the drawbacks of these screw types. This objective is achieved due to the fact that the screw head is supported on the screw shank such that it cannot be moved for providing an optimal reducibility of the vertebrae, wherein a movable ball element is present in the screw head, which facilitates the introduction of the linking member and fixates the same once the introduction has been effected.

Abstract: The embodiments herein are directed to bone-joining or bone-bridging intervertebral implants with an inner channel-type structure of channels, which extend from a bone contacting-surface of the implant to the inside of the implant, whereby the vertical channels are connected by horizontal channels which allow a X-ray beam to go through the implant by passing through a horizontal channel.

Abstract: The present invention relates to a device for the distraction of the spinous processes of two adjacent vertebrae. The spinous processes of the two vertebrae are supported on two separated distraction means being attached to a central body which can be expanded in an infinitely variable manner. The central body can be moved apart in an infinitely variable manner and be fixated along at least one guiding means. By moving apart the central body, the distraction means are expanded along the axial axis and thus distract the spinous processes of the two vertebrae supported on them. Furthermore, holding means can provide for a stable positioning of the implant and prevent an unwanted movement of the device after the implantation.

Abstract: The invention relates to intervertebral disc implants that imitate the natural freedom of movement and facilitate translational and/or rotational displacements of the intervertebral disc in relation to the base plate, independently of the possible displacements of the base plate in relation to the intervertebral disc. To achieve said displacements, the intervertebral disc is mounted on the base plate by means of the fixing elements located in the interior of the implant, in such a way that translational and/or rotational displacements can take place. In addition, the bearing surface between the top plate and the intervertebral disc is spherical, thus maximising the contact surface.
