摘要：
FIELD: medicine.SUBSTANCE: device for the correction of displaced cervical articular process positions comprises a composite body of a head and a cylindrical base, upper and lower supporting platforms, outer surfaces of which face the vertebral bodies and have pointed flanges. The upper supporting platform is mounted on the head of the composite body. The upper portion of the base comprises a T-flange, projection sides of which are guides for female grooves mounted in the lower portions of the head. The head and base are connected by a thread rod having smooth ends, a diameter of which is less than the diameter of the middle thread portion of the rod. One end of the rod is provided with a closed hole for a box spanner, is mounted in a transfer sleeve having a thread along the outer side surface and a slot at the end face. The sleeved rod is mounted in a through hole in the composite body perpendicular to its long axis. The threaded sleeve thread is created in the hole only in the portion of the base, while the thread of the middle of the threaded rod - on the portion of the head of the composite body. The device also comprises an end plate that can be detachably laid on the head of the composite body The upper surface of the above plate has a horizontal portion with notches inserted into the vertebral body at the side of the dislocation, while two adjacent smooth portions inclined at various angles are mounted on the side of the intact articular process. The lower supporting platform having four diametrical vertical notches on the side surface is integrated with vertical and central threaded rod having four long grooves, a position of which corresponds to the position of the above notches, and a recess on the free end. A cup with a through hole in the middle provided with a long projection is formed on the rod the hole has the shape and size corresponding to the long grooves on the rod the notch of the side surface is coaxial with the flange in the hole on the verti
