RU187728U1 - ORTHOPEDIC INSERT FOR COMPENSATION OF LOWER LIMB SHORTING - Google Patents

Abstract

An orthopedic insert for a shortened lower limb refers to medicine, namely to prosthetic and orthopedic products, and can be used as an insert into standard shoes of all age groups of users when shortening one leg.

The insert includes a rigid orthopedic part made in the form of a continuous sole. The height of the liner on the heel side is equal to the difference in leg lengths. Part of the liner in the gel part of the foot is made with through holes. The diameter of the holes and the distance between their centers are determined by the weight of the person.

The technical result is manifested during the operation of the liner and is to provide comfort when walking due to giving sufficient depreciation and uniform distribution of the load on the entire surface of the liner. In addition, shoe symmetry is created for an outsider. 6 c.p. f-ly, 5 ill.

Description

The utility model relates to medicine, namely to prosthetic and orthopedic products and can be used as an insert in standard shoes of all age groups of users when shortening one leg ..

Orthopedic boots for compensating shortening of the lower limb from 5 cm are known from the prior art (RU No. 184768, IPC АВВ 7/16, publ. 11/08/2018), designed to compensate for shortening of the lower limb from 5 cm, including soft and hard orthopedic parts, orthopedic insole with a braid.

With all the advantages of this technical solution, its main disadvantage is that it can be used only in the cool / cold season. While in fairly warm weather, the user of these boots will feel a state of discomfort, the foot will be fogged.

Known insert in the shoes under the heel when shortening the legs (file: /// G: / insert / Insert under the heel when shortening the legs of the online store.html), which has a complex geometric shape, the upper heel and partially gel surface of which is made in the form of a figure , resembling a quadrangle, one of the smaller sides (the heel part) of which is made in the form of an arc, the lower part is made with a bevel towards the bend of the foot. In addition, the liner is solid.

 The shortened hard liner does not provide support for the entire foot and does not allow changes in shape and size depending on the position of the foot.

The disadvantage of this insert is that when placed in the shoe, it can be displaced in the longitudinal direction, which will cause pain in adjacent joints and the spine, which in turn will cause lameness and discomfort. In addition, the cut may not coincide with the bulge of the shoe, for this reason, there will also be a shift in the liner and cause pain in the joints.

The main disadvantage of this insert is that it can only be used in shoes with dense walls, otherwise it will slip on the inner surface of the sole and bring inconvenience to its user. In addition, a sharp transition from the heel may not coincide with the inner oval of the sole, which will cause inconvenience to the user when walking.

The technical problem to which the proposed utility model is directed is to develop a liner design with the ability to reliably compensate for the existing shortening of the lower limb, optimize the biomechanical parameters of walking, excluding the occurrence of pain in adjacent joints and the spine, keeping the distal lower limb in a given equinus position, as well as create symmetry for the viewer in a pair of shoes.

The technical result consists in providing convenience during operation of the liner by imparting sufficient amortization and even distribution of the load on the entire surface of the liner.

To achieve the specified technical result in an orthopedic insert for a shortened lower limb, including a rigid orthopedic part, according to a utility model, it is made in the form of a solid sole, the height of which on the heel side is equal to the difference in length of the legs, and the working part of the insert is made with through holes, the diameter of which and the distance between the centers of the holes is determined by the weight of the person.

Wherein:

- the liner is made of polypropylene;

- the upper surface of the liner is equipped with a leather insole glued to the surface of the liner;

- the transverse dimensions of the liner correspond to the width of the foot in the respective sections;

- the difference in the size of the liner with respect to the dimensions of the inner surface of the sole along the entire perimeter does not exceed 2 mm;

- the length of the liner corresponds to the length of the foot.

The proposed utility model is illustrated by drawings.

In Fig.1 shows the location of the liner 1 when walking under the foot, in Fig. 2- designated parts of the foot: pos. 2- the forefoot, 3- the middle (gelenic) part of the foot, 4- the back (heel of the foot); in FIG. 3 shows a top view of the insert with holes, in FIG. 4 is a vertical sectional view of the insert; FIG. 5 shows the location of the liner under the foot.

The proposed liner is designed to be inserted into any type of shoes. When using the liner, for example, when walking in sandals, the latter must be placed, for example, in the toe, which will ensure its reliable position in the shoes when walking. In the same way, you can use the proposed liner when walking without shoes, for example. around the room. In this case, it is better to use socks that undergo little stretching, for example, nylon.

When walking with the inventive liner, the entire foot is in a state of work.

The proposed form and principle of operation of the liner in shoes change the mechanics of the impact of the legs on the liner. This is due to the fact. that in the gel part the insert is made with through holes, which ensures mobility of the insert with the foot when walking. Thus, the foot, being in constant motion, does not experience additional loads, which provides comfort when walking and does not cause pain, since biomechanical indicators of walking are optimized, the occurrence of pain in adjacent joints and the spine is excluded, the distal part of the lower limb is held, the spine occupies vertical position.

The diameter of the holes depending on the weight of the person is preferably, for example, with a weight of 63-65 kg of the order of 8 mm, and the distance between the holes is approximately 25-27 mm. Before the manufacture of the liner, an outline of the foot is made, according to the size of which the liner is selected. The length of the healthy and shortened legs is measured and the height of the heel of the liner is calculated by the difference.

The proposed insert has passed many years of pilot testing by the inventor himself with a positive result.

The proposed utility model meets the criterion of "novelty," because the prior art did not identify technical solutions with the proposed set of features and the criterion of "industrial applicability", because the proposed insert is made and used by the author for several years with a positive result.
