The disadvantage of this construction is that the fixing elements (Kirschner wires) can only be
Furthermore, it is not possible to join the fractured fragments or parts using sutures, which cannot be achieved with Kirschner sutures
Due to its corrugated structure, the guide is not placed directly on the bone, so longer wires must be overused

Embodiment Construction

[0024] The guide body shown in Figure 1 consists of a flat or curved plate with a thickness of 2-5 mm, made of a metal material suitable as an implant or made of a plastic material (including a biodegradable plastic material). The plate contains a plurality of openings 2 in the form of holes with a diameter of 2-6 mm connecting the top surface 3 and the bottom surface 4 of the guide body 1 . The openings 2 are arranged in such a way that the centers of at least three openings are not located on a straight line. The opening 2 is intended to receive a surgical fixation element 10, such as a wire, staple, peg or screw with a diameter of 2-6 mm. In FIG. 1 these elements are Kirschner wires with an external thread 11 and a sharp front end 12 . The central axes 5 of at least two of these openings 2 are in an oblique relation to each other, so that the fixing elements 10 can be arranged in three dimensions. The central axis 5 of the opening 2 preferably forms an angle of 50-90° wit...

Abstract

The invention relates to a surgical guide body (1) which is designed to receive longitudinal fixation elements (10) such as wires, nails, pegs or screws which are to fixed to the bones. The inventive guide body comprises an upper side (3), a lower side (4) and at least three openings (2) connecting the upper side (3) to the lower side (4) of said guiding body. The centre point of said openings is not located on a straight line. The central axes (5) of at least two of the openings are skewed in relation to each other. The guide body (1) enables the fixation elements (10) to be inserted at various intersecting angles. The guide body (1) primarily prevents movement both towards the proximal and distal parts of the fixation elements (10) which extend within the spongiosa or intramedullar region.

Description

[0001] English translation representative of International Patent Application PCT / CH00 / 00129 "Surgical Guide" Synthes AG Chur. field of invention [0002] The invention relates to a guide body for receiving a longitudinal fixation element to be fixed in bone during orthopedic surgery and to a fixation device comprising the guide body according to the invention. Background of the invention [0003] The guide can function as an internal fixator in osteosynthesis and can be used in the proximal part of the humerus or in other locations of the long bones located close to the joint. [0004] A fan-shaped corrugated guide for guiding Kirschner wires is known from US 5,476,467 from BENOIST. The disadvantage of this construction is that the fastening elements (Kirschner wires) can only pass through guide rods that are parallel to each other. Furthermore, it is not possible to use sutures to connect fragments or parts of the fracture, whereas such connections cannot be achieved w...
