FIELD: medical equipment.
SUBSTANCE: invention relates to medical equipment, namely, to apparatus applied in traumatology and orthopaedics. Apparatus for stabilisation and repositioning in fractures and fracture-dislocations of the bones of the foot and ankle joint includes the following: a base, a foot fixator, movable bars with a working tool assembly for screwing into bone fragments, a leg fixator, and heel fixators. The design of the foot fixator allows the apparatus to be used for both the right and left foot, wherefor holes are provided in the base. The clamping bar of the foot fixator and the stand of the clamping bar of the foot fixator are connected to the base through the holes corresponding to the right or left foot. The guide of the movable bars is connected to the base and secured. The movable bar is positioned by moving a threaded sleeve along the guide of the movable bars. After the required position is set, the movable bar is secured on the threaded sleeve by a fixing element. The working tool for screwing into bone fragments is installed in the attachment fixture, and the working tool for screwing into bone fragments is secured by using the attachment fixture. The attachment fixture for the working tool for screwing into bone fragments is connected to the movable bars. The leg fixator is connected to the base. The position of the leg fixator can be adjusted. The leg fixator is connected to the heel fixators and the clamping bar of the leg fixator. Method for repositioning bone fragments in fractures and fracture-dislocations of the bones of the foot, wherein the above apparatus is used. The foot is placed in the apparatus and steadily secured in the area of the distal region and heel. In the area of the distal region, the foot is secured with a clamping bar by screwing in the attachment fixtures of said clamping bar. In the heel area, the foot is secured by screwing the heel fixators on both sides. The leg fixator is adjusted by the length of the foot by moving along the base of the foot fixator. The fixator stand of the foot fixator clamping bar is installed between the first and second toes, thereby limiting the sliding of the foot in the apparatus. The leg is secured by the leg fixator and the leg fixator clamping bar by connecting on both sides with attachment fixtures. A movable bar guide with movable bars is installed on the base of the foot fixator. The movable bars are installed at the required distance relative to the fracture line. As they move along the movable bars, the working tools for screwing into bone fragments are adjusted relative to the fracture line, then the working tools for screwing into bone fragments are screwed into the bone fragments. Due to the movement of the working tools for screwing into bone fragments along the movable bars and the height adjustment thereof relative to the foot, displacement of the bone fragments in height and width is eliminated. Traction or distraction of the bone fragments is executed using the threaded sleeves of the movable bar. After the displacement thereof is eliminated, the bone fragments are secured intraosseously with metal structures is performed, and then the apparatus is removed. Method for providing first aid during transport immobilisation of the bones of the foot and the ankle joint, wherein the above apparatus is used. The foot is placed in the apparatus and steadily secured in the area of the distal region and heel. In the area of the distal region, the foot is secured with a clamping bar of the foot fixator by screwing in the attachment fixtures of the clamping bar. In the heel area, the foot is secured by screwing the heel fixators on both sides. The leg fixator is adjusted by the length of the foot by moving along the base of the foot fixator. The fixator stand of the clamping bar is installed between the first and second toes, thereby limiting the sliding of the foot in the apparatus. The leg is secured by the leg fixator and the leg fixator clamping bar by connecting on both sides with attachment fixtures.
EFFECT: expanded scope of technical means applied for temporary stabilisation and repositioning during treatment of fractures and fracture-dislocations of the bones of the foot and the ankle, and possibility of stabilisation and repositioning of bone fragments in a given position, transferring stretching and compression forces (distraction and compression) to the bone fragments.
