摘要:
Bone-setting device comprises two elongated holders which are joined by an elongated connecting link. Pins which can be screwed into bone elements are held in each holder in such a manner that they can be rotated around their axis, moved along that axis, and clamped. At least one holder comprises spherical guiding bodies, each of which holds a pin in such a manner that the pin can be pivoted in space. The connecting link comprises a sleeve and a stud which is held in the sleeve in such a manner that it can be shifted in the axial direction and pivoted, and which, in order to generate a force which presses the bone elements against each other, can, by means of a tensioning screw inserted in it, be pulled against one end of sleeve and clamped in various pivoting and sliding positions by means of a clamping screw. The device offers many adjusting possibilities for setting the bone elements but is, nevertheless, very rigid in the clamped state and also relatively small and easy to handle.
