Embodiment Construction

[0038] The threaded joint for supporting the fracture of the posterior pelvic ring basically consists of a threaded rod 1 combined with a threaded nut and an anatomically shaped spacer 2 .

[0039] figure 1 The threaded joint used to support the fracture of the posterior pelvic ring is schematically shown.

[0040] Spacers 2 are positioned between the ilium of the pelvis and known threaded nuts. threaded nut not in figure 1 shown in .

[0041] figure 2 A side view of the pelvis with a spacer 2 on the ilium is schematically shown.

[0042] One spacer 2 in each case rests on the ilium.

[0043] image 3 A spacer 2 for supporting a posterior pelvic ring fracture or for stabilizing a threaded joint of the sacroiliac joint is schematically shown.

[0044] The ilium-facing surfaces 3 of the spacer 2 are mutually inclined in at least two planes, the slopes being arranged at an angle to each other. The cross-section of the inclined portion is rectilinear and / or arched. The w...

Abstract

The invention relates to threaded joints for supporting and stabilizing a rear fracture of the pelvic ring or for stabilizing and stiffening the sacroiliac joint, either with a threaded bar in connection with threaded nuts or a screw in connection with the sacrum. The threaded joints are characterized by secure support and stabilization of a rear fracture of the pelvic ring or by secure stabilization and stiffening of the sacroiliac joint. The threaded joint as an implant is, for this purpose, either a threaded bar in connection with threaded nuts for supporting the rear fracture of the pelvicring or a screw in connection with the sacrum. For this purpose, there is a washer between the ilium and the threaded nut or the screw head, the side of the washer that faces the ilium being mutuallyoblique in at least two planes and the oblique surfaces being arranged at an angle to each other. The washer has an opening for the passage of a region of the threaded bar or of the screw, the opening being expanded toward the ilium.

Description

technical field [0001] The present invention relates to a threaded joint for supporting and stabilizing a posterior pelvic ring fracture or for stabilizing and strengthening the sacroiliac joint by using a threaded rod combined with a threaded nut or a screw combined with the sacrum. Background technique [0002] DE 10 2013 005 391 A1 discloses a system for supporting a degenerated sacroiliac joint with a tensioning element held between the left and right pelvis by means of a holding device. To this end, the holding device has a support extending through a hole in the associated pelvis and an associated end piece. [0003] US 6,635,059 B2 contains a screw system for fixation of the sacrum and / or the sacroiliac joint and / or for other bony regions. [0004] In both solutions, simple spacers are used as planar surface structures. When using such a spacer, the compressive force of the screw is concentrated on the ossicle surface of the ilium due to the shape of this bone surfa...
