Abstract

FIELD: medicine.

SUBSTANCE: method involves determining medial foot part condition on K coefficient value, and foot deformity degree as B for the first order platypodia, C for the second order platypodia, D for the third order platypodia and P for hollow foot. Platypodia being found to belong to interval of B, C, or P, the determined interval is divided into three subgroups: 1,2, or 3. Deviation angle is determined for the first toe (NAP) and medial foot part condition is determined. The fifth toe deviation angle (QBR) is determined, and lateral foot part (QBR) condition is determined. Calcaneal angle deviation is determined, and back foot part condition is determined. Medial foot part condition is determined form K coefficient value.

EFFECT: high accuracy simplified method; enabled individual advises to be given concerning treatment course selection.

Description

The invention relates to medicine, namely to the diagnosis of the condition of the foot, and can be used as a screening method for identifying patients with transverse and longitudinal flatfoot, as well as with a hollow foot in military enlistment offices, medical and educational institutions.

From birth or at an older age, most people experience changes in the longitudinal and transverse arches of the foot. The increasing load on the feet, associated with an increase in body weight, leads to aggravation of the deformation of the foot. Existing changes in the foot lead to a violation of its main functions: balancing, locomotor and spring. Given that the foot carries the main load, a violation of its function is reflected in the entire musculoskeletal system of a person and can lead to a number of chronic diseases in the future.

As a prototype, a method for assessing the condition of the foot was selected, which consists in taking fingerprints (plantograms) of the plantar surface of the feet using a flatbed scanner and subsequent processing of these prints by the graphic-calculation method using a computer program [1].

However, the known method does not allow to determine the degree of deformation of the three sections of the foot, as well as the anatomical and functional state of the feet, to give a comprehensive conclusion and treatment recommendations depending on the deformation of the foot.

The task of the invention is the diagnosis of each of the three departments of the foot with the issuance of an opinion on their anatomical and functional state. The invention is aimed at improving the resolution of a flatbed scan, the depth and quality of diagnosis of foot pathology, the integrated assessment of the final conclusions by creating specialized diagnostic algorithms. This is achieved by the fact that the angle of deformation of 1 and 5 toes is divided into 3 degrees. Subsequently, taking into account the state of the forefoot, middle and hindfoot sections, individual and group reports are generated using diagnostic algorithms and their software computer implementation. The method allows to distinguish 4 groups of the anatomical and functional state of the foot (A, B, C and D), on the basis of which recommendations for treatment are issued in accordance with the patient’s foot deformity.

The difference of the present invention is that for the first time it is proposed to distinguish three degrees of deformation of the 1st and 5th toes of the foot, three degrees of the hollow foot, as well as 4 groups (A, B, C and D) and several subgroups (B1, B2, B3 and C1, C2 , C3) the anatomical and functional state of the feet, taking into account changes in all three departments of the foot. In addition, the use of diagnostic algorithms and their software implementation allows calculating the following indicators of the foot: arch height, total length, length of the front, middle and back sections, Weisslog index; Streater index; Streater-Godunov index, the total area of the plantar surface, the area of the front, middle and back of its departments. The method allows to give individual recommendations for treatment depending on the anatomical and functional state of the human feet.

The invention is illustrated by drawings: figure 1 presents a diagram of the calculation of indicators of the foot; figure 2 presents the scheme of the feet with the first degree of flat feet with an individual report, conclusion and recommendation for treatment (Appendix 2); the table presents data on the anatomical and functional state of the foot; Appendix 1 shows the results of a plantographic study.

The invention includes the following sequence of actions.

A scan of the patient's feet is carried out, after which the operator marks the feet in accordance with the sample (Fig. 1). A command is issued to create an individual report.

The calculation of indicators of the state of the departments of the foot, taking into account the following indicators. The normal deviation angle of 1 finger does not exceed 15 °, and 5 fingers - 7 °. The first degree of deformation of 1 finger is in the range of 15-20 °, the second degree is 20-25 °, and the third is over 30 °. The first degree of deformation of the 5th finger is in the range of 7–11.9 °, the second degree is 12–19.9 °, and the third is over 20 °.

The definition of the foot condition group is made taking into account the following criteria:

P - hollow foot

A is the norm

In - the first degree of flat feet,

C - the second degree of flat feet,

D is the third degree of flat feet.

If the diagnostic criterion, in addition to the norm, falls into the interval characterizing the deformation as B and C, then this interval is divided into three parts on the following condition:

0-20% - “1”,

20-80% - "2",

80-100% - "3".

The condition of the foot is determined as follows:

The state of the medial part of the foot (angle at the first finger of the NAP):

Less than 15 ° - A,

> = 15 to 16 ° - B1,

> = 16 to 19 ° - B2,

> = 10 to 20 ° - B3,

> = 20 to 22 ° - C1,

> = 22 to 28 ° - C2,

> = 28 to 30 ° - C3,

> = 30 ° - D;

The state of the lateral part of the foot (angle at the fifth finger of QBR):

Less than 7 ° - A,

> = 7 to 8 ° - B1,

> = 8 to 11 ° - B2,

> = 11 to 12 ° - B3,

> = 12 to 13.6 ° -C1,

> = 13.6 to 18.4 ° - C2,

> = 18.4 to 20 ° - C3,

> = 30 ° - D;

Midfoot condition (K factor):

Less than 0.1 - P1,

> = 0.1 to 0.4 - P2,

> = 0.4 to 0.5 - P3,

> = 0.5 to 1.1 - A,

> = 1.1 to 1.2 - B (foot with a reduced arch),

> = 1.2 to 1.22 - B1,

> = 1.22 to 1.28 - B2,

> = 1.28 to 1.3 - B3,

> = 1.3 to 1.34 - C1,

> = 1.34 to 1.46 - C2,

> = 1.46 to 1.5 - C3,

> = 1.5 - D;

Condition of the back of the foot (heel angle):

> = 5 ° - A,

Less than 5 ° - B.

The method also allows you to calculate the following indicators of the foot: the height of the arch, the total length, the length of the front, middle and rear sections, Weisslog index; Streater index; Streater-Godunov index, the total area of the plantar surface of the foot, the area of the front, middle and back of its departments. The method on the basis of diagnostic algorithms and their computer software implementation creates an individual report with the conclusion and recommendation for treatment, as shown in figure 2.

After examining a group of people, the program generates a group report, which indicates the anatomical and functional state of the foot, as shown in the table.

We have indicated in this way the study of the feet of 150 preschoolers, 489 schoolchildren and 460 students of three universities in Volgograd.
