SU1250277A1 - Arrangement for reposition and fixing of bone fragments - Google Patents

Description

one

The invention relates to medical technology, namely to traumatology and orthopedics,

The aim of the invention is to provide a spatial mapping of each fragment of both bones of the forearm and lower leg.

The spokes 3 are led through one or two bones 17 of the forearm, depending on the type of fracture and the displacement of the fragments. At large angular and linear displacements, the spider 3 is conducted through fragments of the radial bone. A hole diameter of about 2 mm at an angle of 40-50 ° to the bone surface is used to drill holes before the beginning of the cortical layer on the opposite side. In these Figs. 1 schematically shows an apparatus for reposition and fixation of bone.

fragments, general view; in fig. 2 - the twists and turns are inserted into the needles 12, and the needle-containing worn strap with a spherical element, the bodies 11 are brought to soft tissues. Ja-, cutting the needles 12 are fixed relative to

  needle holders 11 with bolts 13, needle holders The device consists of two brackets 1 (or the body 11 - relative to the rods 9 screws-rings), in which distracts 16 are installed and, exposing the rods 9 relative 2, needles 3 and -spits 14. but the external strips 5, rotating them and sec. On the brackets 1, rigidly mounted are moved out over the spherical elements 6, their own strips 5 on which are located the fragments and ensure their fixed spherical elements 6 sec. and axial compression, with open cuts 7. In the center bore-After selection, the necessary Napravte angle x 8 spherical element 6 installed laziness rod 9 and its position zavin Lena rod 9 and angularly Chiva screw 10, the spherical element 6

is compressed, fixing the rod 9 from axial movement and, pressing against the inner surface of the opening of the extension bar 5, fixes the angle of its direction.

The proposed device provides steady osteosynthesis of complex fractures of both bones of the forearm and lower leg at the same time, allowing the bony to be connected with a longitudinal movement followed by fixation with a screw 10. At the end of the rods 9, needle holders 11 are needled with needles 12 that can be axially moved relative to needle holders 11 25 followed fixing with bolts 13. The removable strips 5 are rigidly fastened to the brackets 1 by bolts 14. The distance between the brackets 1 is adjusted by strapping with their large axial and angles The nuts 15 on the distractors of the 2nd displacement, as well as the relative holders 11, are fixed relative to the ZO full ease of installation and good for the rods 9 with the screws 16. sight (for wound control).

The device works as follows.

The spokes 3 are led through one or two bones 17 of the forearm, depending on the type of fracture and the displacement of the fragments. At large angular and linear displacements, the knives 3 are conducted through fragments of the radial bone. A hole diameter of about 2 mm at an angle of 40-50 ° to the bone surface is used to drill holes prior to the beginning of the cortical layer on the opposite side. In these

needles 12 are inserted into the versts, and needle holders 11 are fed to soft tissues. Ja - those needles 12 are fixed relative to
