Abstract: A humerus head implant includes a head cap, a fixing component, and a bone-screw component. The head cap has a shape of half-an-ellipsoid extending into a positive z-direction along the z-axis, in positive and negative x-directions, and in positive and negative y-directions. The extension along the x-direction is in a range of 0.8 to 0.95 of the extension in the y-direction. There is a conical recess having a center axis that is displaced in the negative y-direction with respect to the z-axis and configured to interface with a conical section of the fixing component. This allows for rotation of the head cap relative to the fixing component.

Abstract: A humeral component of a shoulder prosthesis encloses a stem module which has a shank and an upper shank portion with a stem support surface. A joint adapter is adapted to hold either a liner or a spherical cap. The joint adapter has an adapter support surface which interfaces with the stem support surface. Further, the stem support surface and the adapter support surface have corresponding radial arc shaped sections which allow positioning of the joint adapter against the stem module at different inclination angles. For fastening the joint adapter to the stem module, a bolt or screw is provided.

Abstract: A shoulder joint prosthesis has an at least two-pieced humeral head prosthesis, comprising a calotte, or a joint head (3) and a fixing body (5, 7). The latter comprises a fixing piece (15), for detachable connection of the calotte and a mounting section (21), for the at least cement-free anchoring of the fixing device in the bone. The fixing body is preferably of two-piece embodiment, comprising a discoid positioning body (5) with a medial hole and an anchoring body (7), provided for fixing the positioning body (5) to the bone through the medial hole (19).

Abstract: A prosthetic glenoid component for attachment to a glenoid surface of a scapula to replace a natural socket of a shoulder and to provide a bearing surface for a head portion of an arm bone or humerus. The glenoid component has a metal back with integrally formed attachment legs which are cemented into corresponding holes formed in the glenoid surface, and also has an opening for receiving a hollow metal cage which is screwed into the glenoid surface.

Abstract: The present invention relates to a prosthetic glenoid component for attachment to a glenoid surface of a scapula to replace a natural socket of a shoulder and to provide a bearing surface for a head portion of an arm bone or humerus. More particularly, the present invention relates to a metal back glenoid component having integrally formed attachment legs which are cemented into corresponding holes formed in the glenoid surface, and also having an opening for receiving a hollow metal cage which is screwed into the glenoid surface.

Abstract: An apparatus is described for the surroundive fixation of extremities in which a double-walled cuff-forming cushion is used which can be deformed into a sleeve, which can be made vacuum-tight and which is provided with a evacuation valve. A plurality of loose particulate filling bodies is provided in the inner space of the cuff-forming cushion between the two walls and the cushion can be consolidated by evacuation into a stiff stable structure.

Abstract: The device for the ensheathing fixation of extremities, more particularly for the treatment of extremity fractures of the lower leg and thigh, is comprised of a shell-like member (10) of one shell portion or of two reciprocally tightenable L-shaped shell portions (20, 30) possessing an approximately semi-circular cross-section which surround the extremity to be ensheathed, in which, between the shell portions (20, 30) and the extremity, at least one sleeve-like padding is provided whose contents can be evacuated, in whose interior located between the two padding walls, a large number of filling material particles which are movable relative to each other, are provided, while the wall areas of the shell-like member (10) are, at least in part, constructed so as to be latticed and/or ribbed (FIG. 2).

Abstract: A method and apparatus for arthroscopic reattachment of torn tissue to a bone at a surgical repair site using at least one suture anchor and a tissue grasper. The torn tissue is grasped with jaws of the tissue grasper. The jaws include a top and bottom jaw. The upper jaw has an aperture, and the bottom jaw has a U-shaped slot. The aperture and slot are aligned with each other when the jaws are closed. A threaded suture anchor is inserted through the aligned aperture and slot in the jaws of the grasper, the grasped tissue, and into the bone in a single drilling step. An outrigger located on the barrel of the grasper is adapted to receive a drill and align the threaded suture anchor such that the suture anchor is automatically aligned with the aperture and slot of the jaws of the grasper at the repair site. After insertion of the suture anchor the grasper is removed from the repair site.

Abstract: An apparatus for treating fractures in extremities and regions of extremities which is in particular provided for the treatment of extremity fractures in the region of the lower leg, thigh, lower arm and upper arm has at least two shell parts which can be clamped relative to one another which enclose the extremity to be surrounded. Deformable and evacuatable vacuum-tight cushions having at least one valve and in which there are located a plurality of filling bodies, which are movable relative to one another, in particular small grained filling bodies, are provided between the shell parts and the extremity.
