 The invention relates to medicine, namely to traumatology, and is intended for the operative treatment of patients with a dislocation of the end of the clavicle in the rum-clavicular joint.

The purpose of the invention is to increase the reliability of the articular ends.

FIG. 1 and 2 depict the proposed retainer; in fig. 3 - a screw with a two-step thread.

The clamp for the acromioclavicular joint contains a horizontal rectilinear plate 1 with a two-prong fork 2 at one end, located at an acute angle to the rectilinear part, and an arcuate part 3 at the other end, which has a fastening hole 4 with a thread below. the screw 5. The screw 5 is made stepwise with a working end of a smaller diameter than the fixing.

The fixer is applied as follows.

After appropriate preparation, consisting in layer-by-layer exposure of the clavicle and acromioclavicular joint, eliminating the soft tissue interposition, using an awl or a drill, two recesses in the clavicle are inserted into which the tooth of the fork 2 is inserted and then completely immersed in the bone tissue. At the same time, the clavicle can also be located in the unallocated co-sprained (dislocated), which creates convenience in the implementation of this pas of fixation and does not require additional efforts by the surgeon to hold the articular ends of the clavicle-acromial joint in the position

with research institutes.

Aligning the acromial end of the key, adapts the arcuate part 3 of the retainer to the acromial process of the scapula. Screw-in screw 5, press the end of the working end to the cortical layer of the acromial process, and the head to the clamp, while the arcuate part 3 of the clamp is pressed to the acromial process

blades and thanks to the counter-directed force of the fork 2 and the screw 5, the structure is stabilized.

The fixer of the proposed design is easy to use, it can be used in any medical institution in the treatment of dislocations of the acromial end of the clavicle in an operative way.

The proposed fixator for the key-acromial joint allows the joint ends of the acromio-clavicular joint to be securely retained in the correct relationship after the dislocation of the acromial end of the clavicle is removed and ensures reliable fixation, excluding the use of external plaster immobilization. The latter circumstance has not only an economic, but also a psychological significance, since a certain positive emotional state is created in the patient, and, besides, no personal hygiene measures are required. The retainer also creates convenience in operation, since it does not require an additional surgeon's effort to keep the articular ends of the clavicle-acromial joint in a reduced state when inserting the retainer teeth into the collarbone.
