Orthopedic sole including corrective means for treating metatarsalgia and plantar skin disorders

Abstract

An orthopedic insole capable of being inserted into a shoe or the like for relieving and / or treating skin disorders and / or calluses and / or metatarsal pain comprises at least one semi-rigid corrective element capable of producing an inner metatarsal support, over the rear portion of the head of the first metatarsal, and / or a median metatarsal support, over the rear portion of the second and / or third and / or fourth metatarsal head, and / or an external metatarsal support, over the rear portion of the fifth metatarsal head.

Description

SCOPE OF THE INVENTION[0001]The present invention relates to an orthopedic insole capable of being inserted into a shoe or the like for relieving and / or treating skin disorders and / or calluses and / or metatarsal pain, designed for any person having a skin disorder and more particularly for diabetics in order to prevent the development of ulceration.BACKGROUND OF THE INVENTION[0002]In the field of podology, it is well known that plantar calluses or skin disorders can cause difficulties in walking and can develop into ulceration in the case of deficiency in tissue nutrition, as occurs with patients suffering from so-called type 1 or particularly type 2 diabetes mellitus, or with the elderly having circulatory problems.[0003]A callus is conventionally an excessive formation of normal keratin on the affected site of the body. Its origin can be linked either to disorders such as psoriasis, mycosis or eczema for example, or be purely mechanical. The formation of calluses is said to be a no...

AI Technical Summary

Benefits of technology

[0010]One of the aims of this invention is therefore to remedy these drawbacks by proposing an orthopedic insole of simple design and low cost, adapted to the morphology of the foot of each patient and enabling excess pressure to be eliminated in order to eliminate calluses and relieve patient's pain.

[0017]Advantageously, on its lower face the sole has a recess located in front of the metatarsal heads, at the plantar pad, said recess extending from the inner edge to the outer edge of the sole, and capable of receiving a so-called lower anterocapital element having pre-cut lines in order to enable the creation of at least one hollow under the callus or calluses and / or skin disorders. This enhances the cushioning located in front of the metatarsal heads and, in association with an optional flexible plantar pad, beneath the metatarsal heads on the upper face of the sole. The said lower anterocapital element is pre-cut into five areas so as to create in certain cases a hollow at one or more metatarsal heads in order to reduce the pressure on said head or heads.

Problems solved by technology

In the field of podology, it is well known that plantar calluses or skin disorders can cause difficulties in walking and can develop into ulceration in the case of deficiency in tissue nutrition, as occurs with patients suffering from so-called type 1 or particularly type 2 diabetes mellitus, or with the elderly having circulatory problems.

The formation of calluses of mechanical origin basically appears to be due to excessive pressure that is too great and over too long a period during walking.

This excessive pressure can be due to anatomical anomalies that can cause a modification in gait and dysfunction in the mechanics of the foot, such as anomalies of the rearfoot and forefoot, digital deformations or bony excrescences for example, and / or extrinsic factors such as shoes that are ill-fitting, worn for too long, unsuitable, etc., or sporadic or intensive sporting activities that can cause an excessive load on certain parts of the body for example.

Nevertheless, all these treatments and all these soles do not correct the cause of the appearance of calluses so as to prevent them from regularly reappearing.

Moreover, despite the treatments, it is sometimes possible to see suppuration occur, linked to an infection of the serous bursa located beneath the callus that can lead to ulceration, particularly among diabetics.

This type of sole, apart from the fact that the thickness of between 1 and 10 mm of the raised elements is too great causing too much discomfort for patients making this type of sole totally unusable, does not allow the cause of the appearance of calluses to be rectified because the retrocapital bar is located behind the metatarsal heads.
