METHOD OF TREATING ACROMIOCLAVICULAR JOINT DISLOCATION Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: using a drill with a diameter 4.3 mm a channel at the base of the coracoid process is formed between the attachment points of conical and trapezoidal ligaments. Two "block systems" are modelled, each of which includes a non-absorbable, woven, polyester thread with diameter of 1 mm and two support platforms in the form of titanium buttons with four holes in sizes of 4×12 mm each, for that holdout platforms of "block-systems " are bound, carrying out the thread through their central holes in two plies and leaving the thread ends from one side. The holdout platform of each "block-system" is introduced into the previously formed channel. Two through channels are formed with drill with a diameter 4.3 mm in the collarbone at the places of attachment to it of conical and trapezoidal ligaments. Remaining holdout platforms of each "block-system" are passed through the channels formed in collarbone from the bottom up, for that the loop is conducted through the channels in collarbone with the help of Deschamps needle, leaving its ends out of the wound, the loop is tied with thread, previously conducted through the unengaged hole of holdout platform, remaining holdout platforms are egested through the collarbone channels by pulling the ends of the loop thread, conducting one holdout platform in each channel. Holdout platforms pull together among themselves by uneven tension of ends of "block-system" threads, ensuring the removal of dislocation and reduced acromioclavicular joint fixation. The ends of threads are connected by 3 nodes.

EFFECT: method helps to achieve both vertical and horizontal stability in acromioclavicular joint, to reduce the risk of relapse.
