SU772536A1 - Device for reposition and fixation of lawer jaw bone fragments - Google Patents

Description

Using screw connection 9; which is connected to the hinge 10. The working part of the bracket 7 contains two threaded holes 11 for the screw connection 9. The input element and the fixture consists of. pads 12 with a groove 13 movably movable by means of a screw connection 14 with a support member. The working portion of the pad 12 includes a pivot stop that consists of a screw pusher 15 having a longitudinal hole 16 for inserting a pin with a stop 17, and a hinge 18, which has a through screw hole for the screw pusher of pin 15. For fixing the hinge in the desired plane serves as a clamping washer 19 and screw 20.

The device is applied after splinting the patient and marking on the skin of the fracture level and the lower edge of the displaced jaw fragment. Through a puncture of the skin, the movable corrective hook-plug 3 is inserted beyond the upper edge of the zygomatic arch. Then the hook-wrist is put on the supporting element 1 so that at the same time the fixed zaxBat 2 enters through the puncture of the skin under the lower edge of the lower jaw in the area of its angle. The binder 8 is positioned over the zygomatic bone, the plates of the corrugated joint 5 are aligned, the shaped nut 4 is clamped, and the clamping nut 6 is positioned to securely fix the support element between the zygomatic arch and the angle of the lower jaw. eg to the lower edge of the displaced fragment and fragment reponning. After reposition, they put the pad 12 on the screw connection 14 so that the outer length of the pin with the stop 17 enters the longitudinal hole 16 of the screw

pusher pin 15, after which the screw connection 14 and the screw 20 firmly fix the direction and position of the screw pusher 15.

If necessary, the rotation of the screw pusher 15 achieve the desired more accurate reposition of the displaced jaw fragment. After achieving the necessary reposition, the device serves as a fixative.

The device provides controlled closed reposition and fixation of the articular process and upper sections of the lower jaw branch when they are shifted outwards - downwards, which prevents possible frequent complications and extensive trauma of soft tissues associated with the operation, facilitates the postoperative period, shortens the period of treatment, accelerates rehabilitation of the patient.
