Abstract: An instrument set for connecting vertebral bodies, comprising a screw which can be screwed into a pedicle, a head piece which can be connected polyaxially to the screw for coupling to a rod system and which has a sleeve-shaped tulip having an opening for insertion of the screw head in an insertion direction, and a tool, is developed. The head piece has a saddle in the tulip, with a receiving region for receiving the screw head in a first end region that faces the opening and a coupling region that can be coupled to the tool in a second end region opposite the receiving region. The saddle can be moved between a released position and a locked position. In the locked position, the screw head cannot be disengaged from the receiving region, and the saddle can be fixed in a released position.

Abstract: An instrument set (1) for connecting vertebral bodies, comprising a screw (10) which has a screw head (12) and a shaft (14) and can be screwed into a pedicle, a head piece (2) which can be connected polyaxially to the screw (10) for coupling to a rod system (100) and which has a sleeve-shaped tulip (20) having a first insertion opening (21) for insertion of the screw head (12) in an insertion direction (E), and a tool (40), is developed according to the invention in that the head piece (2) has a saddle (30) in the interior region (22) of the tulip (20), the saddle (30) has a receiving region (32) for receiving the screw head (12) in a first end region (31a) that faces the first insertion opening (21a) and a coupling region (35) that can be coupled to the tool (40) in a second end region (31b) opposite the receiving region (32), and the saddle can be moved between a released position (23a), which can be reached by inserting the screw head (12), and a locked position (23b), which can be reached by moving the sc

Abstract: Implant for stabilization of pelvic ring fractures, comprising a nail for intraosseous implantation, a fixing agent and at least one locking element for relative fixation of the pelvic bone to the nail. The nail is designed so that the nail intraosseous be passed through a pre-drilled by a sacrum through channel or in the sacrum predrilled through channel is intraosseous insertable. Wherein the pin has at least at its first end of the nail transverse implementation for receiving the locking member, said locking member having an anchoring portion by means of which it can be anchored in a pelvic bone, and a locking portion connected to the transverse conducting of the nail so corresponds to the locking element with the nail is stable angle lockable. Wherein the nail is fixed by means of fixing means at the second end of the nail, in a first pelvic bone and/or the sacrum, whereby the nail is secured by means of the locking element relative to a second pelvis against rotation and displacements fixed.

Abstract: A bone screw is disclosed for attaching a spinal fixing element. The bone screw includes a threaded screw shank that can be fixed in place in a bone and a screw head having a fastening area for fastening a fastening device for the spinal fixing element. The fastening area includes a threaded section for fixing the fastening device in place. The screw head includes a recess differing from a threaded section. The recess has a longitudinal axis and allows for non-sliding accommodation of an extension of the fastening device laterally to the longitudinal axis of the recess. The extension of the fastening device engages the recess, the fastening device is rotatable about the longitudinal axis of the recess, and the threaded section extends in the longitudinal direction of the recess. The threaded section may be a hole and, together with the recess, a stepped hole.

Abstract: A vertebral column replacement body or spacer has first and second anchoring sides each facing in the mounted or implanted state of the body an adjacent vertebra, wherein each anchoring side has a tooting for ensuring that displacement in the ventral or dorsal directions is safely prevented. The vertebral column replacement body has two body elements which are slidingly guided relative to each other and transversely of the anchoring sides, wherein, after a desired relative position has been reached, a first body element can be braced against the second body element by radially widening the first body element.

Abstract: A device for stabilizing vertebrae of a spinal column has a stabilizing rod and clamps each having a receiving bore for receiving the stabilizing rod. The clamps each have a first leg and a second leg. Each leg has a transverse bore extending transversely to the receiving bore. The transverse bores of the first and second legs are aligned with one another. Screws having a first threaded portion for threadingly engaging a vertebra are provided. The screws have a screw head remote from the first threaded portion and a second threaded portion projecting from the screw head in a direction away from the first threaded portion. At least the transverse bore of the first leg of the clamps have a bore insert member inserted in the transverse bore and resting against the outer surface of the first leg and having an eccentric insert bore. The second threaded portion of the screws penetrate the eccentric insert bore.
