Abstract: The invention relates to a club head (1) for a golf club, comprising an impact plate (4) for teeing off a golf ball. The club head also comprises a shell (2) produced from a first material, on which the impact plate (4) is attached, a core (3) at least partially surrounded by the shell (2) and produced from a second material, and at least one weighting element (6; 6a, 6b) produced from a third material. The second material of the core (3) has a lower density than the first material of the shell (2). The third material of the weighting element (6; 6a, 6b) has a higher density than the first material of the shell (2) and/or than the second material of the core (3). Preferably, at least one sensor unit (5) is also provided, which is arranged at least partially inside the core (3).

Abstract: Disclosed is a device comprising at least one intervertebral implant (3) and at least one plate (4,5) that is to be connected to the intervertebral implant (3) and an adjacent spine (21-23). The intervertebral implant (3) is connected to at least two spaced-apart plates (4,5). One end of both plates (4,5) respectively forms a fixable joint along with the intervertebral implant (3). Preferably, at least one of the plates (5,4) is embodied in a Z-shaped or L-shaped manner. The inventive device provides for great adaptability to the anatomic characteristics of the spinal column and a modular structure while the number of parts is kept small.

Abstract: A fastening element (1) to be inserted into an opening, or bore (2) of a work piece (3) is provided having a shaft (5) that is insertable into the bore (2) and has a roughened and/or profiled surface (4), and optionally includes a stop collar (6). The fastening element (1) is preferably formed from a fiber reinforced, elastically deformable material, and its shaft (5) can be or is inserted into the bore (2) in a force-fitting manner under an elastic deformation.

Abstract: An implant used in stabilising operations on the thoracic and lumbar vertebral column for restoring the load-bearing capacity of the vertebral column is provided. An insertion region of the implant (I) comprises a wedge-shaped distraction part (C), which permits the vertebral bodies to be pushed apart in order to increase the intervertebral distance. In addition, guide elements in the form of grooves (7) and/or strips are provided on said wedge-shaped distraction part (C) and/or in the implant part (D).

Abstract: The invention concerns an implant in the form of a compression resistant hollow body (1), used in procedures for stiffening the vertebral column (2). The hollow body (1) includes two open receptacles (3, 4) mutually oriented toward one another that interlock and form the implant proper (cage). The two receptacles (3, 4) can be separated by pressure through insertion of a filling material, thereby producing an expansion of the hollow body (1) after it has been implanted.
