Description

 The invention relates to medicine, in particular to traumatology.

 A number of devices and apparatuses are known for treating dislocations of the acromial end of the clavicle. Some of them stably fix the clavicle in the set state) significantly limit the function of the limb / A.N. Edinak, 1975 /, which requires a longer rehabilitation. Other devices represented by spoke systems / G.S.Sushko, 1974; O.K. Tsikh, 1984; I. B. Kaplan, 1965 /, are technically complex, they use from three to seven knitting needles, which increases the invasiveness of the intervention and the risk of infectious complications. The simpler of them / N.I. Petrushenko, 1970; I.B.Devin, 1965 / do not provide stability of fixation.

 In some devices, the axillary cavity is an anti-support of the fixed clavicle / A.T. Kokhter, 1969 /. A common drawback for them is the instability of fixation when moving with a limb, patient discomfort, and sometimes the risk of compression of the axillary vessels and nerves.

 The closest technical solution is the apparatus of G.V. Tikhonov et al. / AS USSR N 992042, class. A 61 B 17/18, 1983 /. However, when using the Tikhonov apparatus, there is no uniform constant pressure on the clavicle when moving in the shoulder joint during fixation. Another significant drawback is that even with a small amplitude of movements, the stresses in the screw-bone system increase and constant pressure on the clavicle is not maintained.

 The objective of the invention is to provide uniform constant pressure on the acromial end of the clavicle while maintaining the function of the upper limb for the duration of fixation.

 "The task is achieved due to the fact that for the treatment of dislocations of the acromial end of the clavicle, a device containing a screw clamp, a bracket with adjusting and fixing nodes with a system of fastening to the body with straps is used, while the screw clamp is made with two supporting platforms and connected to the bracket by spring plate, and the system of attachment to the body is represented by trims with a chest, lumbar and hip belt fixed to them. "

The invention is illustrated by the following figures:
In FIG. 1 shows a General view of the device.

 In FIG. 2 shows an example of fixing the device to the human body.

 In FIG. 3 shows the latch.

 In FIG. 1 shows a device consisting of a screw lock - 1, made in the form of a finger with threaded ends 19, 20 and supporting platforms - V, G / upper - B spherical /; spring plate - 2 with a central ellipse hole - A and two holes along the edges for hooks of the spring, springs - 3; a supporting bracket, consisting of a traverse - 4 with holders - 5 and racks - 6 with adjusting screws - 7, which, by means of earrings - 8 connect the springs - 3 to the plate - 2. Traverse - 4 is fixedly connected to the bar - 9 and the belt - 10 for fixing the braces on the patient's chest. With a strap - 9 and with the possibility of moving relative to each other by means of a groove - B and fixing screws, a strap - 11 is connected with a lumbar and hinge-attached hip straps - 12, 13. Holders - 5 have the ability to move along the horizontal axis of the beam and fix a certain position / lengths / screws - 14.

 Adjustment and fixation of the uprights - 6 in the vertical position is carried out with nuts - 15, 16, 17. To eliminate distortions when installing the plate - 2 and to eliminate tension in the screw - bone system on the screw retainer - 1 the upper supporting platform - B is made spherical (see figure .3). The plate - 2 is fastened to the latch by the nut - 18.

 The required force / 2-8 kgf / at the end of the clavicle is created by adjusting the struts - 6, which changes the length of the springs -3 stretching and accordingly increases the force.

 To maintain the function of the limb and create support on the torso and the area of the hip joint, the system for attaching the yoke - 4 to the torso consists of 3 belts - 10,12,13.

 The device is used as follows.

 After the necessary skin treatment and local anesthesia, an incision is made / up to 0.8 cm long / 1-1.5 cm medial from the acromioclavicular joint. In the clavicle, a channel is drilled with a 3.2 mm drill through the incision, into which a screw lock is implanted - 1. The lower supporting platform is immersed in soft tissue and presses on the clavicle. The spring plate - 2 is attached to the clamp with a nut - 2. The supporting bracket is inserted into the armpit, the traverse system is fixed with straps - 10, 12, 13 to the body and the hip joint, adjusting the holders apart - 5 traverses - 4 and fixing them with screws - 14. Produced reduction of dislocation of the acromial end of the clavicle, after which a spring-loaded spring plate - 2 is attached to the support bracket.

Immobilization in this device up to 5-6 weeks. Movement in the elbow joint in full, movement in the shoulder joint - abduction up to 120 ^o . After removing the device, exercise therapy is assigned to the shoulder joint.

Example:
Bnoy Grechkin V.I., 36 years old, I.B. N 3286, was admitted to the hospital 04/23/97, / in 1 injury.decl. /, After 8 hours from the moment of injury.

 Diagnosis at admission: Closed complete dislocation of the acromial end of the left clavicle.

 The patient was taken to the operating room, where, after the necessary skin treatment and local anesthesia, an incision was made up to 0.8 cm long, 1.0 cm medial to the acromioclavicular joint. In the collarbone through an incision, a 3.2 mm drill bit was drilled into the channel into which a screw lock was implanted. The lower supporting platform is immersed in soft tissue and presses on the collarbone. A spring-loaded plate is attached to the latch with a nut. The support bracket was inserted into the armpit and secured to the trunk and hip joint with straps. Reduction of the dislocation of the acromial end of the clavicle is performed, after which the spring-loaded spring plate is attached to the support bracket / see figure 2/.

 04/30/97 g, the patient was discharged from the hospital / after 7 days /, for outpatient treatment. The device was removed after 5 weeks. The patient, a professional photographer, did not give up his professional activities during the treatment. To remove the device, the function of the limb practically did not suffer.

 The proposed method allows for uniform, constant pressure on the acromial end of the clavicle while maintaining the function of the upper limb.

 This device can be used with fresh dislocations of the acromial end of the clavicle in order to early restore limb function. Thus, the task is achieved.
