Abstract: A wrist prosthesis has distal and proximal sections, which are connected with one another by a curved bearing.

Abstract: The present invention relates to an intervertebral implant for insertion between two vertebral bodies of a spinal column, comprising a body containing two contact faces, whereby the body is designed as a hollow body, and the hollow body is formed by a side wall which has a convexly curved longitudinal wall portion and a concavely curved longitudinal wall portion as well as two convexly curved lateral wall portions connecting the two longitudinal wall portions with each other, whereby the radii of curvature of the lateral wall portions are smaller than the radii of curvature of the longitudinal wall portions.

Abstract: The present invention relates to an osteosynthesis device with a bone screw and a correction rod, in which the correction rod is placed in a bifurcated head of the bone screw and axially fixed. To that end, the bifurcated head has structure that prevent the longitudinal displacement of the correction rod.

Abstract: A ventral intervertebral implant is used between two vertebral bodies of a spinal column. The implant has an upper and a lower contact surface and at least one anchor pin projecting beyond at least one of the contact surfaces. An instrument is provided for engagement with the implant and which extends as many anchor pins as are provided relative to the contact surfaces. The instrument is removable from the implant.

Abstract: An osteosynthesis device having a bone screw, particularly a pedicle screw, a fork head that has a groove and a corrective pin seated in the groove of the fork head. A corrective pin is secured against twisting in that the bottom of the groove of the fork head is provided with a plurality of longitudinal slots lying parallel to one another.

Abstract: In an orthopedic surgical holding device for a correcting rod, having a bone plate which can be fastened on the bone, a receiver device for the correcting rod and a fixing device maintaining the correcting rod in the receiver device. An optimal transfer of the occurring forces and moments is achieved in that the bone plate can be fixed independently of the receiver device (10) and has a bearing for the receiver device, and in that the receiver device can be pushed into the bearing from the proximal side and in the course of this extends through the bone plate and extends beyond it on the distal side for receiving the correcting rod.

Abstract: In a bone surgery holding device for a fixing rod, with a bone plate, which can be fastened to the bone, a receiving device, and a fixing device, which secures the fixing rod in the receiving device, the bone plate has a contact face essentially made to fit the surface of the bone and the fixing rod can be inserted into the receiving device.

Abstract: In an osteosynthesis device, a bone plate is secured to a bone with at least two bone screws and the bone screws serve to bear and receive two rods, via which the correction and stabilization of the bones takes place.
