Abstract: In the event of bone fractures, in particular comminuted fractures, having multiple bone fracture pieces, a quick and safe operation can be possible when implements (1) are used for stabilizing the affected bone (6). The main body (2) of these implements is an angle profile (15), wherein long recesses (17-19) are provided in the plate side pieces (10, 11). This facilitates any bending that may become necessary about the longitudinal axis (9) and the transverse axis (16). In this way, it is possible to achieve a high level of stability for the operated region, in order to guarantee an early functional exercising of the neighboring joints without risking the bone fragments shifting again.

Abstract: Photodynamic devices for stabilizing a joint are provided. In some embodiments, a photodynamic joint spacer is provided that includes an expandable member configured for attachment to a bone having an excised region; a formable bar configured for attachment to the bone along at least a portion of the expandable member; and a light-sensitive liquid passed into the expandable member to expand the expandable member, wherein the expandable member is shaped by the formable bar to a shape resembling the excised region of the bone, and wherein the light-sensitive liquid is curable upon exposure to light energy to set the expandable member in the shape resembling the excised region to form a photodynamic joint spacer.

Abstract: The invention relates to an intramedullary awl assembly for opening the bone upon a femur nailing with a guide of a guide tool equipped with a hand grip, and an awl with a working tip equipped with an actuating handle. The guide is formed by an angle plate which is arranged on the end of the guide tool opposite the hand grip. The angle plate has a guide hole in the one arm, and an anchoring tip provided on the side of the other arm facing the bone. A shank of the guide tool acts on the top of the other arm in alignment with the central axis of the anchoring tip.
