Abstract: A method of treating a distal radius fracture that produces a bone fragment at a radius shaft, including the steps of: obtaining: a) an osteosynthesis plate with a long, proximal leg and a short, distal leg; and b) a distancing element; fastening the short, distal leg to the bone fragment with the distancing element acting between the long, proximal leg and the radius shaft so that the distancing element maintains the long, proximal leg at a specific angle with respect to the radius shaft; removing the distancing element from between the long, proximal leg and the radius shaft; pressing the long, proximal leg towards the radius shaft to thereby reposition the bone fragment relative to the radius shaft; and fastening the long, proximal leg to the radius shaft.

Abstract: The invention relates to a repositioning device for the handling of distal radius fractures by means of a T-shaped osteosynthesis plate, comprising a long leg and a short leg, disposed in a T-shaped and angular manner in relation to said long leg, wherein the short, distal leg has a face that comes into contact with the distal fracture fragment and a number of openings for bone screws and the long, proximal leg is intended for making contact with the proximal bone near the body. To improve the repositioning device in such a way that the required tilting of the articulated face in the palmar direction of the osteosynthesis plate used can be carried out in an angularly faithful manner, the lower face (14) of the long, proximal leg (13) of the T-shaped plate (7) that is facing the proximal bone or radial shall (11) is provided with a spacer (15), in order to keep the long leg (13) at a certain angle (?) in relation to the proximal bone (11) near the body.

Abstract: In order to simplify the implantation of an orthopedic fixation system for securing a first bone fragment to a second bone fragment with a support screw which can be screwed into the first bone fragment by means of a bone thread, with a support sleeve surrounding the support screw and guiding this so as to be freely displaceable in longitudinal direction and with a bone plate which has at least one threaded bore, can be secured to the second bone fragment and into the threaded bore of which the support sleeve can be screwed by means of an external thread, it is suggested that the bone thread, on the one hand, and the threaded bore and the external thread, on the other hand, have the same pitch of the thread turns and that the bone thread have one thread turn and the threaded bore as well as the external thread have at least two thread turns located next to one another with a correspondingly smaller width of each thread turn.

Abstract: In order to secure the screw-in position of a bone screw in an optimum manner in the case of an implant with a threaded bore for receiving the bone screw screwed into it, it is suggested that a fixing member be held on the implant in the direction of the bore adjacent to the threaded bore, this fixing member having an opening which is aligned with the bore and has a diameter which is smaller than the external diameter of the outer edge of the threads of the bone screw, and that the fixing member consist of a material which is so soft that the threads of the bone screw dig into this material or displace it when the bone screw is screwed into the threaded bore of the implant.

Abstract: The invention relates to a fixation device for externally adjusting bone fragments. A pair of members anchored to the bone fragments are connected to each other to allow a longitudinal displacement of the fixing unit. According to the invention the connection of the members is defined by a hinge configuration which allows guiding and aligning both members when the fixing unit is released for stimulating the healing process. A bracket is mounted on a parallelogram hinge to generate a pressure or, respectively, a tension force to move the bone fragments apart or draw them together. According to the invention the hinge configuration comprises telescopic members centered by spring means.

Abstract: What is described is a leg-supporting means for making restrained X-ray photographs of the knee joint. In order to obviate the disadvantages of the apparatus which are on the market for making X-ray photographs of the knee joint, more especially the unstable position of the proband leg and shift instabilities with small degrees of flexion, provision is made for a thigh section or member with two clamping members movable concentrically relatively to one another to be connected to a ring enclosing the X-ray zone for the knee joint, and for the ring with the thigh member to be rotatable relatively to a lower leg member about its center and by up to 90.degree. towards both sides.
