Definitions

  • the present invention relates to a surgical holding device and a method for temporary fixation of an osteosynthesis plate and its alignment with respect to a bone.
  • the applied plate can be primarily only temporarily fixed to the bone until the optimal location is found and confirmed by fluoroscopy. As soon as the optimal position of the plate is confirmed, however, this positioning of the plate should also not possible change until a final fixation by means of screws is done. Depending on the anatomical localization, this required temporary fixation of plates to the bone sometimes causes considerable problems. Usually, the following procedures are practiced.
  • Pliers have already been developed which, on the one hand, temporarily fix the position of bone sections to one another during repositioning and at the same time make it possible to arrange an osteosynthesis plate, see, for example, CN 2708855, US Pat. No. 1,985,108 and US Pat. No. 2,460,470.

  • the created plate must multiply by a few Millimeter be corrected in all directions, since there is usually no direct insight into the injured articular surfaces of the wrist. For this, multiple fluoroscopic controls are often required, especially in more difficult fracture forms. Any unintentional slippage of the temporarily fixed plate costs unnecessary surgery time and increases the radiation exposure. Furthermore, there is a risk of injury to the radial artery, median nerve, and tendons on the extensor side of the wrist when using unsuitable clips.
