Description

The field of technology to which the invention belongs

The invention relates to medicine and can be applied in the field of podology for restoring the nail by complex chemical and mechanical treatment of the nail and nail bed, by applying alpha-hydroxy acid to the nail bed of the fingers and toes, as well as mechanically removing strong formations of horny layers and unstable areas of the nail .

State of the art

Nails can be considered derivatives of skin cells. The nail is made up of many structures. The horny nail plate grows out of the matrix, which is located in the proximal part of the nail plate. The nail is located in the nail bed, to which it is tightly attached. When removing a nail under normal conditions, it grows on the hands in about 5 months, and the nail on the feet takes twice as long. If the nail bed has a good blood supply, then the nail grows, receiving appropriate nutrition.

In case of adverse internal or external effects on the nail, nail diseases occur that affect the performance of the hands and feet.

The most common diseases include onycholysis - detachment of the nail plate. Onycholysis can be caused by both acute injuries (for example, being hit by a heavy instrument) and chronic (as a result of frequent lifting of too long nails). Other causes of nail separation include bacterial, fungal, and viral infections of the nail apparatus, skin conditions such as psoriasis, lichen planus, and alopecia areata, certain medications, and systemic diseases (including diabetes, thyroid disease, porphyria, and many others).

In the process of onycholysis, epithelialization of the nail bed occurs (the formation of a new skin pattern with a papillary pattern) or hyperkeratosis of the nail bed (excessive thickening of the stratum corneum against the background of slowing down the desquamation of dead cells). In these cases, the nail cannot adhere to the nail bed.

To restore nail growth or mechanically, the affected nail plate is removed or it is mechanically cleaned by removing the surface layer.

A known method of restoring the nail according to patent No. 2660991, including the processing of the remaining nail plate and the formation of a nail prosthesis, characterized in that the adhesive is applied along the visible boundaries of the nail plate, without entering the surrounding soft tissues, the applied adhesive is exposed to air until completely dry and a shiny film is formed , polymerization of the applied adhesive is carried out, the Nolatek mass is applied and its polymerization is carried out, then the cured prosthesis is filed, top varnish is applied and its polymerization is carried out.

A known method of nail extension, device and materials on it, written in patent No. a layer of material for nail extension, drying the nail in the lamp for 5-10 seconds, cutting the material to the desired length and shape, smearing the nail with the material with a modeling layer, drying the nail in the lamp for 5-10 seconds, giving the nail the desired shape, cooling the material using a damp cloth, if necessary, removing irregularities with a file, applying a filling layer, adding volume by applying an additional filling layer, drying the nail in a lamp for 30-60 seconds, cooling the material with a damp cloth, if necessary, applying a modeling layer on the back of the nail .

The disadvantage of this solution is that the extension molds made of synthetic plastic have a standard size, that is, they do not provide the possibility of an exact match with the proportions of any person's nail.

Known compositions and methods for the treatment of nail disease, specified in patent No. 2519664, including local application to the surface of the nail of a pharmaceutical composition containing a linear or branched aliphatic lower alcohol, one or more esters dissolved, suspended, dispersed or emulsified in the specified alcohol formula RCO- OR', where each of R and R' independently represents a linear or branched alkyl, alkenyl, alkoxycarbonylalkyl or alkoxycarbonyloxyalkyl radical having from 1 to 25 carbon atoms, the active pharmaceutical ingredient KP-103, and a volatile silicone selected from cyclomethicone and dimethicone, and wherein the composition is applied in an amount and for a time sufficient to reduce the severity of the symptoms of the disorder.

The disadvantage of this solution is the complexity of the preparation of this pharmaceutical composition and the low percentage of patients cured.

The closest in terms of the achieved result to the proposed invention is the method described in patent No. 2253386, in which, at the first stage, rejected or hypertrophied layers of horny cells of the nail are removed by layer-by-layer grinding with a diamond bur head until pathological defects are detected in the layers of the nail or under the nail plate and eliminate them. or straightening. Then take a break of 3-7 days. At the second stage, the newly rejected layers are removed and a subsequent break of 3-7 days is made. The stages of polishing the torn layers are carried out until the growth of the plate is restored to its free edge, while smoothing and polishing the surface of the nail with nail files. Lotions with dimexide are also used in the course of treatment.

However, the mechanical impact on the nail with the help of a diamond bur without preliminary softening of the nail and subungual bed causes discomfort to the patient, which makes the entire treatment process painful, and also does not guarantee the absence of recurrence of nail disease.

Disclosure of invention

The objective of this invention is to increase the simplicity and availability of the method for restoring nail growth, reduce the cost of treatment, eliminate the occurrence of pain in the patient during the application of procedures, increase the effectiveness of treatment and reduce the number of relapses of nail disease.

This goal is achieved through a complex effect on the nail and nail bed, namely through chemical action by applying alpha-hydroxy acid to the nail bed of the fingers and toes, i.e. by soft action on the nail bed with alpha-hydroxy acid, which ensures its exfoliation, restoring elasticity to the upper layer of the epidermis, as well as mechanical action by removing strong formations of horny layers and unstable areas of the nail.

The procedure is carried out in several stages. At the first stage, antiseptic treatment of the nail and nail bed is carried out, as well as mechanical removal of strong formations of horny layers with a diamond burr and unstable areas of the nail with a cutting tool, at the second stage, a 1 ml alpha-hydroxy acid solution is applied to the nail bed with an applicator and held for 1-2 minutes. In this case, within the framework of one procedure, it is permissible to apply the solution three times after 5-7 minutes. In the future, the procedure is repeated after 3-5 days. Then the procedure is repeated after 2 weeks, and then once a month until the nail is restored in the nail bed.

Implementation of the invention

At the first stage, antiseptic treatment of the nail and nail bed of the finger is carried out. After the antiseptic treatment of nails with a cutting tool, unstable areas of the nail plate are removed, i.e. parts of the nail are removed at the point where the nail plate leaves the nail bed. If there are strong formations of hyperkeratosis (horny layers) on the nail bed, then these layers are additionally removed with a diamond bur head. In this case, the removal of unstable areas and grinding is carried out in such a way that it excludes the occurrence of pain in the patient.

Next, a solution of alpha-hydroxy acid 1 ml is applied to the treated surface of the nail bed with an applicator and the exposure is maintained for 1-2 minutes. During one procedure, it is permissible to apply the solution three times at intervals of 5-7 minutes.

The action of the alpha-hydroxy acid solution is observed after 3-5 days, in which a crust forms on the nail bed, which is carefully removed by mechanically removing the surface layer with a diamond bur or tweezers.

The procedure is repeated after 2 weeks. Subsequently, depending on the state of nail growth, the procedure is carried out once a month for 3-7 months until the nail growth is fully restored.

During the application of the solution, a mild exfoliation of the stratum corneum of the epidermis was observed without any traumatization of the nail bed with a noticeable acceleration of tissue repair, growth of the nail plate to the nail bed and improvement of the trophic tissue of the nail apparatus.

As a result, there is a complete restoration (regeneration) of the primary appearance of the nail apparatus.

Implementation examples:

Example 1

Patient Margarita, 32 years old. Complaints about changes in the nail plate of the 1st finger of the right and left foot, expressed in the absence of a part of the nail plate, impaired growth and growth in the distal direction. Treatment by a dermatologist with various medications did not give a positive result. During the examination, it was revealed that the nail bed, with a long absence of the nail plate, was epithelialized (became smooth) and slightly hypertrophied (rose up). These circumstances hampered the growth of the nail and the growth of the nail plate to the nail bed. After treatment with an antiseptic, unstable sections of the nail plate were removed mechanically. There was no need for grinding. The second step was double application of alpha-hydroxy acid with an applicator.

The procedure was repeated two weeks later. An unstable section of the nail plate was also removed. After that, a 1 ml solution of alpha-hydroxy acid is applied with an applicator and the exposure is maintained for 1-2 minutes.

The treatment was carried out for 4 months, after which a stable result appeared. The nail plate began to adhere to the nail bed. By the sixth month, the nail had fully recovered.

Example 2

Patient Anna, 35 years old. Complaints about symmetrical degeneration of the nail plate of the 1st toe of the left and right foot. It is expressed in turbidity, thickening and disruption of the growth of the nail plate in the distal direction, which appeared after four surgical removals due to ingrown nail plate. Lack of aesthetic appearance. Surgical removal and treatment with various medications did not give a positive result. The examination revealed hyperkeratosis, deformation of the nail plate and hypertrophy of the distal edge, X-ray revealed subungual exostosis (bone and cartilage growth in the area of the last nail phalanx of the toe) of the first toe of both feet. This made it difficult for the growth of the nail plate. After antiseptic treatment, hyperkeratosis and unstable areas of the nail were removed by grinding with a diamond bur head. Next, a solution of 1 ml of alpha-hydroxy acid was applied to the nail with an applicator three times with an interval of 5 minutes.

The procedure was repeated two weeks later. The procedure was then carried out once a month. Already in the fourth month of use, an increase in the growth of the nail plate was observed. By the seventh month of application of alpha-hydroxy acid, a stable result was observed and the growth of the nail plate to the bed. Nail growth to the free edge occurred 8 months after the start of recovery, which is normal.

Example 3

Patient Diana, 25 years old. Complaints about changes in the nail plate of the first toe of the left foot. It is expressed in discoloration, thickening and disruption of the growth of the nail plate in the distal direction, which appeared after a long wearing of the gel polish coating. Lack of aesthetic appearance and pain. Treatment with various medications did not give a positive result.

After antiseptic treatment with a cutting tool, unstable areas of the nail plate were removed, and subungual hyperkeratosis was removed by grinding with a diamond bur head. Under the removed nail, a slight deformation of the bed and a deformed newly growing nail were found. Next, a single application of alpha-hydroxy acid 1 ml was made with an applicator.

The procedure was repeated two weeks later. Grinding was also carried out with a diamond bur head to eliminate roughness. An alpha-hydroxy acid solution was applied once to the cleaned nail bed. Subsequently, the procedure was carried out once a month. Recovery, i.e. accretion of the nail to the bed and accretion to the distal edge occurred two months after the start of the use of alpha hydroxy acid. This corresponds to the normal growth of the nail plate. No drugs were used to prevent onychomycosis and bacterial infections.

The proposed method was tested on 80 patients, the results are shown in the table.

Table Pathological conditions of the nail Number of patients Elimination of a defect in the nail abs % abs % Total onychomycosis ten 16.6 ten 100 Total onycholysis with fungal infection 60 100 45 75 Onycholysis traumatic 60 100 60 100 Hyperkeratosis of the nail bed 35 58.3 35 100 Epithelialization of the nail bed 45 75 45 100 Deformation of the nail bed 26 43.3 26 100 Changing the color of the nail ten 16.6 ten 100

From the data presented in the table, it follows that in all 80 patients with nail growth disorders, various pathological conditions of the nails were revealed. When using the proposed method in all patients, it was possible to eliminate all defects that impede nail growth, as well as restore the nail, with the exception of patients with total onycholysis with a fungal infection.

Compared with the prototype, the proposed method allows you to: 1) eliminate pain during the application of procedures; 2) shorten the recovery time of nail growth; 3) Significantly improve the blood supply to the nail; 4) restore the color of the nail.

Findings:

As a result of the treatment, recovery occurred in all the cases described above, the average duration of nail restoration was about four months. The use of the invention in comparison with the prototype made it possible to exclude the risk of trauma to the nail bed, avoid pain in patients, significantly reduce the cost of the course of the nail restoration procedure, reduce the drug load and the number of relapses, provide effective prevention of onycholysis, with a noticeable acceleration of tissue repair, growth of the nail plate to the nail bed while improving the condition of the nail bed tissue.

Thus, the above examples indicate that the treatment of the nail bed with alpha-hydroxy acids contributes to the gentle removal of hyperkeratosis, prolonged hydration of the nail apparatus due to its properties. This leads to rapid recovery and growth of the nail plates to the nail bed.

Achieved by the proposed method, the restoration and improvement of nail growth is a fundamentally new technique for the treatment of onycholysis and onychodystrophy.
