Abstract

METHOD OF ARTODRODZA OF THE HEAVY-MIXED JOINT, including the formation of a canal in the articular bones and the introduction of a graft into it, characterized in that, in order to reduce the trauma of the operation and ensure the self-compression of the articular articular ends, the canal is formed at the level of the articular cleft through the base of the inner ankle, block talus and distal epiphysis of the tibial bones.

The invention relates to medicine, namely to operative orthopedics.

There is a method of arthrodesis of the ankle joint, including the formation of a canal in the articular bones and the introduction of a graft 1 into it.

However, this method is traumatic and, when performed, does not create conditions for the self-compression of the articular ends.

The purpose of the invention is to reduce the morbidity of the operation and to ensure the self-compression of the articulating articular ends.

The goal is achieved in that according to the method of arthrodesis of the ankle joint, including the formation of a canal in the articular bones and the introduction of a transplant, the canal is formed at the level of the joint space through the base of the inner ankle, the block of the talus and distal epiphysis of the tibial bones.

The method is carried out as follows.

A longitudinal incision of 4-5 cm in length exposes the base of the inner ankle and skeletal the periosteum in the anteroposterior direction. The foot is fixed in the position of light plantar flexion (95-100 °). A spear-shaped, and then a conical cutter with a diameter of 2/3 from the anterior-posterior size of the base of the inner ankle, forms a channel in the transverse direction, passing at the level of the articular gap through the base of the inner ankle 2, the talus block, the distal epiphysis of the tibial bone. Then, the face milling cutter gives the cavity the shape of a cylinder over the entire width of the block of the talus, which in an adult is on average 3 cm.

The area of resection of the articular cartilage can be increased by shaping several channels running fan-like from the base of the inner collar and in the plane of the joint space.

The second stage of the operation is the removal of the bone autograft from the crest of the wing of the iliac bone. The PaJBMepbi graft depends on the size of the narrow canal. The length of the graft should be 1-2 mm longer than the canal length, and the width of the graft should be 3-4 mm longer. If it is necessary to take a graft in thickness that exceeds the diameter of the formed channel, then two grafts are taken. We can procure a graft in the form of small ones; fragments and crochets with a total volume of about 15 cm. Before the introduction of the monolithic graft, they are shaped into a cylinder that is 1 mm larger than the width of an analog in diameter.

When pressing the graft into the canal, a wedge effect occurs, as a result of which you create an internal self-compression of the arthrodesic ends

bone medication spongy graft. With the introduction of kroshkovidnogo transplant last tightly tamped into the channel with a lining and a hammer. After the graft is injected, the soft tissue wound is protected. The limb is immobilized with a circular plaster cast up to the middle third of the thigh for a period of 3-4 months. The proposed method is reliable reduces trauma operation, applicable regardless of age and associated diseases.
