An intervertebral implant for insertion into an intervertebral disc space between two adjacent vertebral bodies of a human or animal spine. The intervertebral implant has an implant top side, which defines a first vertebral body abutment face for abutting against a first vertebral body, and an implant bottom side, which defines a second vertebral body abutment face for abutting against a second vertebral body. The intervertebral implant comprises a frame structure with at least two support elements. The at least two support elements extend from the implant top side to the implant bottom side. The at least two support elements define support element longitudinal axes, which run transversely, in particular perpendicularly, to the first and/or second vertebral body abutment face.

A stent retractor has a radially flexibly expandable tubular sheath divided in the peripheral direction into at least two sections, specifically a reinforcing section and an expanding section, with radial flexibilities that differ from one another, these sections being interconnected integrally. The stent retractor includes axial segments that are connected by a puzzle-type connection allowing simple separation or length adjustment in the axial direction (including when in situ) while also being made integrally, for example by a laser or water jet cutting method, preferably from a tubular blank.

An implant is provided which allows for widening of the vertebral canal of vertebrae with less stress on the patient than in heretofore customary surgical procedures, wherein the vertebral arch of a vertebra is cut through, forming an incision gap, or is partially removed and the implant is inserted in the incision gap, wherein the incision gap is bounded by incision faces opposed to each other and the implant comprises an implant body having two contact faces which in the inserted state in the incision gap contact the incision faces of the vertebral arch.

A system for anchoring a pedicle screw in a patient's vertebra uses a pedicle screw having a threaded portion sinkable in the vertebral arch. The space between the threaded portion and cortical edge layer of the pedicle is at least partially filled by a spacer that enables an all-round support of the threaded portion at the cortical edge layer. A kit includes a pedicle screw and a spacer which at least partially fills the space between the threaded portion and cortical edge layer of the pedicle. A spacer has an essentially oval cross-section for form-locking fit in a corresponding axial recess sunk in the pedicle and having an axial through-hole to accommodate the threaded portion of a pedicle screw, as well as a spacer in the form of an essentially cylindrical pedicle augmentation in the form of a bone screw or a bone bracket.

To provide a method with which expansion of the vertebral canal of vertebrae is possible with less stress for the patient than with the surgical methods used to date, it is proposed that herein the vertebral arch be split and an incision gap thereby be formed, and the incision gap bounded by opposed incision surfaces be expanded to a prescribed gap width and the bone substance of the resulting vertebral arch sections thereby be elastically/plastically deformed.

A surgical guiding instrument for a surgical machining tool has a substantially elongated instrument body having a proximal end and a distal end and defining a longitudinal axis. The instrument body carries a guiding device for the machining tool that can be used in minimally invasive surgery. The guiding device is arranged and constructed so as to enable the machining tool to be positively guided by it along a path of movement defined by the guiding device. The path of movement corresponds to a superimposed translational-pivotal movement.

In order to improve an implant for the dorsal stabilization of a human or animal spinal column, comprising an attachment device for placing in position against and/or fixing to spinous processes of adjacent vertebrae of the spinal column, such that it can be used for the dynamic dorsal stabilization of the spinal column, it is suggested that the implant comprise at least one spacer element which is associated with the attachment device and designed in such a manner that it alters its external shape and/or its elastic properties as a result of a change in ambient conditions and/or forces acting on it. Furthermore, an improved implant system for the dorsal stabilization of a human or animal spinal column is suggested.
