RU56807U1 - REHABILITATION DEVICE FOR INJURIES OF THE Ankle Joint - Google Patents

Abstract

The device relates to medicine, namely to traumatology and orthopedics. The purpose of the device is the simultaneous distraction and development of movements in the ankle joint under a metered load. The device is used in the postoperative period at the rehabilitation stage in patients with injuries of the ankle joint, as well as after prolonged immobilization (damage to the bones of the lower leg, including the ankles, feet). A woolen toe is put on the operated lower limb, then shoes with lacing and a special ebonite insole inserted into it, having holes in the sole, at the level of the axis of the developed limb. Shoes are tightly laced. The foot fits on the Beller tire. A strong thread is drawn through the holes in the insole and sole of the shoe, for which the load is suspended. The weight of the cargo is selected individually.

Description

The well-known "Rehabilitation footrest", designed for auto-development of the joint under a dosed load (Application No. 92006111, Mikhailenko VV, RU, from 1992.11.13). A foot rail with a base in the form of a Beller tire consists of supports on the busbars. On the supports fixed by screws, a frame is mounted with an axis passing through the foot platform with lock nuts on the threaded ends. A spring bracket is attached to the frame rack, which is attached at the other end to a loop at the bottom of the platform. On the top of the platform, a rake-shaped stopper is slidably mounted, thrown with teeth on the spine located on top of the frame. On the platform, a thrust bearing and a hinge are fixed.

The disadvantage of this device is the complexity of the device, as well as the lack of distraction of the ankle joint, which can subsequently lead to the development of such a complication as deforming osteoarthritis.

Known "Cuff for traction of the lower extremities" (Patent No. 2106847, Shavianidze G.O., Grigoryeva V.D., RU, from 1998.03.20.), Intended for the treatment and development of joints of the lower extremities. Divorced plates are applied to the ankle joint. The cord is tightened, and the plates tightly fit the foot at the level of the ankle joint. The cuff provides distraction of large joints of the lower extremities, including the ankles.

The disadvantage of the cuff is the inability to create a metered load aimed at the development of the ankle joint.

The purpose of the device we offer is to create conditions for simultaneous distraction and development of movements in the ankle joint under a metered load, as well as to accelerate the regeneration processes under the influence of static electricity arising from a special selection of materials for the toe and insole of the product, such as wool and ebonite.

The technical result is achieved by the inclusion of special shoes (3) (Fig. 1), tightly fixed to the foot, for example, using lacing, a special insole (1) (Fig. 1) with holes for a strong thread (2) ( Fig. 1), the insole has identical shoe openings in the sole (4) (Fig. 2), a special toe cap, a strong thread (5) (Fig. 1, 2), a set of weights (6) (Fig. 1, 2) of different weights, supports for the limb with devices for skeletal traction, for example, Beller tires (7) (Fig. 2).

The device can be used in the postoperative period at the rehabilitation stage in patients with injuries of the ankle joint, as well as after prolonged immobilization (damage to the bones of the lower leg, including the ankles, feet).

A special toe is put on the operated lower limb, then special shoes with an insole inserted into it. Shoes, toe and insole are the same size as the patient’s foot. Shoes are tightly fixed on the foot (laced). The limb is placed on the Beller tire, a strong thread is stretched through the corresponding holes in the insole and sole of the shoe before putting on the patient’s foot. After laying on the tire, the load is suspended on the thread. The holes in the sole and insole are located so that the thread drawn through them is a continuation of the axis of the lower limb (axial extension). The weight of the load is selected individually, depending on the required load. The material for the manufacture of the insole and sock is selected so that when they rub against each other, static electricity

(e.g. wool sock and ebonite insole). The device carries out the distraction of the ankle joint at rest, with passive and active movements of the developed limb during physiotherapy exercises, and also helps to dose the load, thanks to a set of loads of different weights.

The device is used at the rehabilitation stage - the development of movements in the ankle joint - in patients with injuries of the ankle joint, as well as after prolonged immobilization (damage to the bones of the lower leg, including the ankles, feet).

With a prolonged absence of movements in the ankle joint (damage, prolonged immobilization of the limb), the nutrition of the articular cartilage is disturbed. Degenerative-dystrophic changes occur in it, which reduces its resistance to damaging factors. Thus, when developing movements in the joint as a result of friction against each other, the changed cartilage is damaged, which subsequently leads to the development of deforming arthrosis. When using our device, the joint is developed simultaneously with its unloading. Due to the force of gravity acting on the load, and through it on special shoes and, accordingly, the foot, the distance between the distal and proximal articular surfaces of the ankle joint (joint gap) is slightly increased, which is sufficient to create a more gentle mode of operation of the changed cartilage. When developing a joint in our device, friction practically does not have a damaging effect on the articular surfaces of cartilage. Development occurs less painfully, in a shorter time, the risk of deforming arthrosis is reduced. In addition, the negative electric charges that occur when a special sock is rubbed against a special insole have a positive effect on bone tissue regeneration.

Clinical example.

Patient X., 41 years old, was admitted to the traumatology department of VOKB No. 1 in a planned manner on April 12, 1999, medical history No. 4338/3, with complaints of pain in the left ankle joint. The diagnosis is a chronic closed fracture of the ankles, the posterior edge of the tibia of the left lower leg with a dislocation of the foot posteriorly. He was injured on January 5, 1999, was treated at the place of residence in a plaster cast. It does not exclude the possibility of secondary displacement of fragments. On the radiograph of the left lower leg with the capture of the ankle joint in direct and lateral projection from 04/12/1999:

fracture of the ankles, posterior edge of the tibia with posterior dislocation of the foot, subchondral osteoporosis of the talus and tibia. The left ankle joint is deformed, flexion and extension are sharply limited due to pain. Patient X refused from arthrodesis of the left ankle joint. On April 16, an operation was performed - osteosynthesis with screws and knitting needles. The postoperative period was uneventful. In the early postoperative period, patient X. underwent a rehabilitation course aimed at developing an ankle joint with its unloading, using a device for the rehabilitation of patients with injuries of the ankle joint. April 30 was discharged for outpatient treatment. As a result, the function of the ankle joint was preserved. In January 2001, when Patient X. was admitted to the trauma unit of VOKB No. 1 to remove metal structures, he walks without additional support, does not limp, the restriction of movements in the left ankle joint is insignificant.
