The invention relates to medicine, in particular to orthopedics.

There is a method of treatment of congenital dislocation of the hip in children by gradually hip abduction up to 80 - 90o(position Lorenz 1), and then fix the

The disadvantages of this method are: the remaining contracture causing muscles and narrowing of the neck of the capsule of the hip joint and interpolatory limbus.

These shortcomings are partly addressed by the use of devices, giving the chance to make a distraction along the axis of the hips after full discharge. Known, for example, apparatus for closed reduction of dislocation of hip in children [1], which is the closest analogue.

The objective of the invention is improving the efficiency of treatment by providing opportunities centration of the femoral head in the acetabulum and prevent complications associated with gross manipulation of the hip joint, which is achieved dosed reduce pressure on the femoral head with simultaneous stretching of the neck joint capsule and smoothing limbus that, in turn, is the prevention of dystrophic changes.

The drawing shows a General view of the design of the distraction device for the treatment of congenital dislocation of the hip in children.

Distraction device contains two horizontal distractor, made in the form of arcs 1 and 2; four vertical distractor 3, paper distracters 3 made in the form of rods and bushings, connected to a threaded connection, is provided with a control elements 4. Horizontal distracters, made in the form of arcs 1 and 2 are also connected by a threaded connection, equipped with similar regulatory elements 4. On the ends of the arcs 1 and 2 installed clamps 5 with screws 6 to 7 spokes of Kirchner.

Distraction apparatus is set so that the point of application of distraction forces are in the lower third of the outside inside of directly thighs, through which the spokes are of Kirchner with soldering and fastened taut clamps 5 with screws 6. Traction hips is strictly proportioned to the calculated radiograph distances of femoral head bone from the bottom of the acetabulum. The tension of the spokes 7 is regulatory elements 4. Threaded connection parts allows lengthening of the spokes 7 to 600 mm and tighten them.

The proposed construction of a distraction device allows for distraction directly thighs dosage gradually overcome contracture of the muscles of the hips, stretch the neck of the capsule of the hip joint, stretch screwed into the joint limbus,action by the apparatus will significantly increase the effectiveness of treatment of congenital dislocation of the hip in children.

Distraction apparatus for functional treatment of congenital dislocation of the hip in children, contains two horizontal distractor and are mounted at their ends clips spokes, characterized in that it is equipped with four vertical distracters connecting horizontal distracters, the horizontal distracters made in the form of arcs connected to a threaded connection, is provided with a control elements, and the vertical distracters made in the form of rods, bushings, also connected to a threaded connection, is provided with a control items, all threaded connections with the regulatory elements of each part of the apparatus are located diagonally with respect to its vertical axis and represent two interchangeable parts.

SUBSTANCE: method involves introducing a pair of fastening members into each vertebra. Controllable elastic force is applied to the pairs of fastening members as unit- or bilateral load in particular cases. It enables one to support forces in continuous way in loading and relaxing vertebral muscles. Device has movable supporting beams connected to each other in specific way with threaded rods each manufactured from plates attached to each other. Two plates are outer and one of them is intermediate. Each plate has two members for fixing vertebra manufactured as screw rods. The plates are connected on one side with elastic member having spring and clamp mounted on threaded rod, one rod end being freely arranged on the plate and the other one being fixed in the plate with single-axle hinge; on the other side with elastic member having spring having hooks and threaded rod, one rod end being fixed in the plate with nuts and the other one is connected to opening in the plate.

EFFECT: enhanced effectiveness of treatment; reduced risk of traumatic complications.
