Abstract
Description
ORTHOPEDIC SOLE OR INSOLE FOR PEOPLE WITH HALLUX VALGUS The invention relates to an orthopedic shoe sole or insole for people with hallux valgus, the orthopedic shoe sole or insole supporting at least toes 1 to 5 and the sole of the foot when walking or in a stationary state, in particular the entire foot from toe 1 to 5 to the heel. The invention also relates to a shoe with an orthopedic sole or insole. Hallux valgus (bunion) refers to a deviation of the first toe (big toe), in which the first toe extends valgically, i.e., from the center of the body toward the second to fifth toes. The direction of pull of the tendons in the foot changes, increasing the displacement of the first toe. At the same time, the head of the first metatarsal bone deviates inward, leading to the typical bunion. In addition to aesthetic problems, a hallux valgus can cause, for example, painful pressure points, skin irritation, swelling, or inflammation due to rubbing against shoes. Consequential damage includes osteoarthritis or overloading of the neighboring joints of the eleventh to fifth toes or the metatarsal bones. This misalignment of the first toe is often caused by a hereditary predisposition and is usually exacerbated by wearing tight shoes or high heels. To a certain extent, hallux valgus can be treated conservatively rather than surgically, for example by performing foot exercises or using foot splints. Foot exercises for treating hallux valgus include exercises that promote free mobility of the first toe in all directions. Foot exercises are preferably performed by a physiotherapist and consist of the physiotherapist mobilizing the patient's first toe and returning it to its initial position. This extension movement of the first toe is carried out simultaneously in the vertical plane of its natural flexion (a movement that also occurs when walking) and in the horizontal plane laterally, opposite to toes II to V. This particularly relieves the symptoms of hallux valgus, but the deformity is not usually corrected by foot exercises.At the same time, flat shoes with sufficient space should be worn in everyday life, particularly in the area of the first to fifth toes and, if necessary, in the area of the big toe joint. Insoles can also be used to support the arch of the foot and prevent the progression of toe extension. In addition, toe separators, toe pads, support insoles, plantar orthoses, and hallux valgus splints are also known for the treatment of hallux valgus. Document US 2018 / 0249782 A1 discloses a single-piece strap sandal with a toe strap. The sole portion under toe 1 can rotate relative to the toe strap. Although the disclosed sandal allows relative movement between toe 1 and toes 2 to 5, this movement is not actively reinforced. Document GB 2536889 A discloses a shoe with separating agents between the individual toes of the wearer, in particular between toe I and toe II. However, relative movement between toe I and toe II is not possible. Based on this state of the art, the invention is based on the objective of providing an orthopedic shoe sole or insole for the treatment of hallux valgus, which allows the patient to perform foot exercises for the treatment of hallux valgus at any time and as many times as desired. The invention relates to an orthopedic shoe sole as specified in independent claim 1. Preferred embodiments of the invention are described in the dependent claims. The object is achieved according to the invention by an orthopedic sole or shoe insole for people with hallux valgus, the orthopedic sole or shoe insole supporting at least toes I to V and the sole of the foot when walking or in a static state, in particular the entire foot from toe I to V to the heel, characterized in that the orthopedic sole or shoe insole comprises a main part and an element movably connected thereto, the movable element being located under toe I and supporting it, and the main part being located under at least toes II to V and the sole of the foot and supporting them, the movable element being movably connected to the main part such that it can rotate in a horizontal plane within the limits of the foot joint of toe I and the sole of the foot about an axis. The orthopedic shoe sole or insole according to the invention comprises a main part that serves to support toes II to V and at least the transverse arch of the foot, preferably the heel in addition to the longitudinal arch. The movable element serves to support toe I and is movably fixed or permanently connected to the main part in the area of the big toe joint (optionally as a separate element). This allows the movable element to move in a horizontal plane relative to the main part, in particular to rotate about an axis within the limits of the toe joint I and the sole of the foot. The movement of the movable part relative to the main part is limited by suitable means. The relative movement, in particular the rotational movement in the horizontal direction, between the movable element and the main part of the orthopedic shoe sole or insole preferably occurs during a walking movement of the patient, in particular caused by the pressure force caused by the patient's own weight on the orthopedic shoe sole or insole. Thus, the orthopedic shoe sole or insole according to the invention periodically generates the known foot gymnastics movement to mobilize the first toe and the big toe joint while walking, so that the patient can independently perform the curative foot gymnastics by walking daily.The movable element therefore preferably moves depending on the load on the foot supported in the horizontal plane with respect to the main part, in particular in the form of a pendulum movement whose axis of rotation is located in the area of the big toe joint. The orthopedic shoe sole or insole according to the invention enables a patient with hallux valgus to independently perform healing foot gymnastics exercises at any time, in particular daily, thereby minimizing the costs of hallux valgus treatment. By simultaneously moving the first toe vertically and horizontally during walking, the first toe and the big toe joint are mobilized. According to the invention, there is a cavity in the main part of the shoe sole or insole under the toes II to V and / or the transverse arch of the foot, in which a hydraulic, mechanical, pneumatic, electrical or other device is installed, which is connected to the movable element and, during a walking movement, causes the rotational movement in the horizontal plane laterally to the main part, away from it, in particular caused by the pressure force caused by the patient's own weight on the orthopedic shoe sole or insole. The cavity in the main part can also be configured between the insole and the shoe sole.Therefore, the orthopedic shoe sole or insole according to the invention generally comprises mechanical, hydraulic, pneumatic, electrical, or other means for achieving relative movement between the movable element and the main part, particularly during the patient's walking motion. This is achieved, for example, by loading the transverse arch and / or toes I to V with the patient's own weight, thereby actuating the hydraulic, mechanical, pneumatic, electrical, or other means. In a convenient variant of the invention, the device for performing the rotational movement is a hydraulic device designed in the form of an elastic casing filled with a gel or other liquid, with a rod at the end, the end piece of the rod being connected to the movable element and periodically actuated by the pressure exerted by the foot on the casing at the beginning of each step. During the walking movement, the patient exerts a force on the casing filled with the gel or other liquid with his own weight, which moves the end piece of the rod and, thus, the movable element connected to it, relative to the main part. If the pressure on the casing is released, the end piece of the rod and the movable element connected to it can return to their initial position. According to an alternative variant of the invention, the device for performing the rotational movement is a pneumatic device configured in the form of an elastic casing filled with air or other gas, with a rod at the end, the end piece of the rod being connected to the movable element and being periodically actuated by the pressure exerted by the foot on the casing at the beginning of each step. The pneumatic variant differs from the hydraulic variant primarily in the means used to move the end piece of the rod. According to another variant of the invention, the device for performing the rotational movement is a mechanical device designed in the form of a leaf spring, which has a first end in the cavity of the main part and is connected to the movable element with a second end, the leaf spring being periodically actuated by the pressure exerted by the foot on the leaf spring at the beginning of each step. This variant can be manufactured particularly simply and inexpensively and is less prone to failure, since no liquid or gaseous medium is required, which could escape, if necessary, if the sole or insole of the orthopedic shoe according to the invention is damaged. in / bin / cznz / B / YiAi In another variant according to the invention, the movable element is connected to the main part of the sole or insole via a plate, which allows the movable element to be locked laterally at different extension angles with respect to the main part of the sole. In general, the orthopedic sole or insole according to the invention comprises means, in particular mechanical means, for fixing the movable element relative to the main part in different positions, regardless of the load on the supported foot. Toe I is thus fixed by the movable element fixed at a certain distance from toe II resting on the main part, the walking movement (foot flexion) creating a vertical movement, by means of which a therapeutic gymnastic movement is also generated, which, thanks to the different adjustable positions, can be periodically adjusted by a physiotherapist.This is particularly advantageous when a simultaneous horizontal and vertical movement is too painful for the patient. According to another advantageous variant of the invention, the movable element comprises a toe attachment (I), such that the toe is guided at all times during the generated horizontal rotational movement. The attachment is achieved, for example, by means of one or more elevations on the movable element or by means of loops or the like. This objective is further achieved by a shoe comprising an orthopedic sole or insole according to the invention. Conveniently, the shoe is designed as an open-front shoe, as this simplifies the relative movement between the main part and the movable element. In a convenient variant, the sole of a shoe according to the invention additionally comprises a base plate on which the movable element can move. Preferably, the base plate is connected to the main part and is integrally formed with it. The base plate prevents direct contact between the ground and the movable element, so that the movement of the movable element is not impeded by friction with the ground. The invention is explained in more detail below using exemplary embodiments shown in the accompanying figures. They show: Figure 1 shows different views of a shoe with a first embodiment of an orthopedic shoe sole according to the invention, Figure 2 shows different views of a shoe with a second embodiment of an orthopedic shoe sole according to the invention, and Figure 3 shows different views of a shoe with a third embodiment of a shoe sole according to the invention. Figure 1 a shows a top view of a right shoe with an orthopedic sole 1 according to the present invention, for people with hallux valgus. The orthopedic shoe sole 1 according to the first embodiment of Figure 1 supports the entire foot from toe 1 to 5 and up to the heel when walking or in a static state. The shoe of Figure 1 consists of the orthopedic insole 1 according to the invention and an upper part 2, which is preferably made of an elastic material. Furthermore, the shoe is conveniently configured to be open at the front to allow relative movement between toe 1 and toes 2 to 5, as described below. Alternatively, the shoe could have a corresponding free space for relative movement. The foot of the shoe wearer is shown in Figure 1 by a dashed line. The orthopedic sole 1 of the shoe in Figure 1 comprises a main part 14 and an element 3 movably connected thereto. The movable element 3 is located under toe I and supports it, while the main part 14 is located at least under toes II to V and the sole of the foot and supports them. According to the first embodiment in Figure 1, the main part 14 supports the foot in the area of toes II to V and up to the heel. The movable element 3 is movably connected to the main part 14 via the connection 5. The relative movement between the movable element 3 and the main part 14 is ensured, for example, by the elasticity of the material used and can be reinforced by the indentations in the form of roundings 6. The roundings 6 prevent in particular the formation of cracks due to expansion processes caused by the relative movement between the movable element 3 and the main part 14. The connection 5 between the movable element 3 and the main part 14 can be formed in one piece, so that both are manufactured from the same base piece, or it can be a subsequently manufactured connection 5, so that both are manufactured independently and then connected. The connection 5 between the movable element 3 and the main part 14 is designed such that the movable element 3 can rotate about an axis 4 in a horizontal plane within the limits of the toe joint 1 and the sole of the foot. The axis of rotation 4 is preferably located in the region of the toe joint 1 (big toe joint). Figures 1b and 1c show sectional views along lines AA and BB, respectively, of Figure 1a. As can be seen in particular from Figures 1b and 1c, a cavity 7 is located in the front region of the main part 14 of the shoe sole 1, in particular under the toes II to V. According to the first embodiment of Figure 1, a hydraulic device is installed in this cavity, which is connected to the movable element 3 and which, during a walking movement, causes the rotational movement in the horizontal plane laterally away from the main part 14, in particular caused by the pressing force generated by the patient's own weight on the orthopedic shoe sole 1. The hydraulic device comprises, for example, an elastic casing 8 in the cavity 7. This casing 8 is filled with a gel or other liquid 9. On the side adjacent to the end face of the movable element 3, the casing 8 comprises a rod 10. This rod 10 is designed, for example, as a corrugated tube, the tube profile having a particularly thread-like shape. In this respect, the rod 10, in particular the corrugated tube, is made of a material having greater strength than the elastic casing 8. The closed end piece 11 of the rod 10 is connected to the movable element 3.The hydraulic device thus designed is periodically actuated by the pressure exerted by the foot at the beginning of each step, in particular a pressure is exerted on the elastic casing 8, whereby the end piece 11 of the rod 10 moves the mobile element 3 with respect to the main part 14 and generates the rotation movement in the horizontal plane laterally to the main part 14, moving away from it. A compression spring can be inserted into the stem 10, particularly the corrugated tube, to adapt the mechanical properties of the hydraulic device, in particular to generate pretension. This allows the pressure required to generate relative movement between the movable element 3 and the main part 14 to be adapted to the individual needs of the patient. On the movable element 3, on the side of toe II, a elevation 12 is expediently arranged, which ensures that toe I can move with the movable element 3. Accordingly, the main part 14 can in / bin / cznz / B / YiAi have on the side of toe I a elevation 13, which fixes toe II and thus also toes III to V in the main part 14. The elevation 12 of the movable element 3 and the elevation 13 of the main part 14 are shown in detail in Figure 1c. Instead of the elevation 12 and / or the elevation 13, a clamp, a loop or the like can also be used to fix toe I to the movable element 3 or at least toe II to the main part 14. When walking, the heel of the foot is raised and the toe is in a horizontal position and the entire weight of the person presses on the elastic envelope 8. The rod 10 expands and extends the movable element 3 to the side. The elevation 12 on the movable element 3 ensures that the toe I moves together with the movable element 3. During each step, the toe I simultaneously performs a movement in two planes, i.e. in the vertical plane together with the other toes II to V and a lateral extension / pendulum movement in the horizontal plane together with the movable element 3 moving away from the toes II to V. When the pressing force is no longer exerted, the movable element 3 and the toe I return to their initial position. If the person is on tiptoe, constant pressure is exerted on the hydraulic device and during this time the moving element 3 separates toe I from toes II to V, which is also a therapeutic gymnastics exercise for patients with hallux valgus. The special method of use, frequency and amplitude of relative movement of the moving element 3 must be specified by the physician, in particular, the orthopedist. Figure 2 shows different views of a shoe with a second embodiment of an orthopedic shoe sole according to the invention 1. The second embodiment of Figure 2 differs from the first embodiment of Figure 1 in that, in the cavity 7, there is not installed a hydraulic device which is connected to the movable element 3 and during a walking movement generates the rotational movement in the horizontal plane which moves the main part 14 laterally away, but a mechanical device which is connected to the movable element 3 and, during a walking movement, causes the rotational movement in the horizontal plane which moves the main part 14 laterally away. The mechanical device according to the second embodiment of Figure 2 comprises a leaf spring 15 having end sections 16. The leaf spring 15 is connected with the right end section 16 through the connection element 17 to the main part 14 of the shoe sole 1. At the junction point between the main part 14 and the movable element 3, the leaf spring 15 is inserted into a groove 18 of the movable element 3 and is connected to the movable element 3 through the axis 19. The leaf spring 15 has an oblong hole 20 for the axis 19 in the end section 16, which is connected to the movable element 3, so that the displacement of the axis 19 occurring during the pivoting / pendulum movement of the movable element 3 can be compensated. Particular details can be found in Figures 2d and 2e, which show sectional views along the lines CC and DD in Figure 2a. The leaf spring 15 has an upwardly curved region 21, as can be seen in particular in the sectional view of Figure 2b, Figure 2b showing a sectional view along the line AA of Figure 2a. The upwardly curved region 21 of the leaf spring 15 presses from below against the upper plane of the cavity 7, as shown in Figure 2b. On the movable element 3 there is a elevation 12 and, on the main part 14, an elevation 13, corresponding to the first embodiment of Figure 1, which fix the toe I or the toes II to V during the relative movement between the movable element 3 and the main part 14. Figure 3 shows different views of a shoe with a third embodiment of a shoe sole 1 according to the invention. Figure 3a shows a top view of a right shoe with the orthopedic sole 1 according to the present invention, for people with hallux valgus. The orthopedic shoe sole 1 according to the third embodiment of Figure 3 supports the entire foot from toe 1 to 5 and up to the heel when walking or in a static state. The shoe in Figure 3 consists of the orthopedic insole 1 according to the invention and an upper part 2, which is preferably made of an elastic material. Furthermore, the shoe is expediently designed to be open at the front in order to flexibly adapt the distance between toe 1 and toes 2 to 5, as described below. Alternatively, the shoe could have a corresponding free space for adaptation. The foot of the shoe wearer is shown in Figure 3 by a dashed line. The orthopedic sole 1 of the shoe in Figure 3 comprises a main part 14 and an element 3 movably connected thereto. The movable element 3 is located under toe I and supports it, while the main part 14 is located at least under toes II to V and the sole of the foot and supports them. According to the third embodiment in Figure 3, the main part 14 supports the foot in the area of toes II to V and up to the heel. The movable element 3 is movably connected to the main part 14 via the connection 5. The relative movement between the movable element 3 and the main part 14 is ensured, for example, by the elasticity of the material used and can be reinforced by the indentations in the form of roundings 6. The roundings 6 prevent in particular the formation of cracks due to expansion processes caused by the relative movement between the movable element 3 and the main part 14. The connection 5 between the movable element 3 and the main part 14 can be formed in one piece, so that both are manufactured from the same base piece, or it can be a subsequently manufactured connection 5, so that both are manufactured independently and then connected. The connection 5 between the movable element 3 and the main part 14 is designed such that the movable element 3 can rotate about an axis 4 in a horizontal plane within the limits of the toe joint 1 and the sole of the foot. The axis of rotation 4 is preferably located in the region of the toe joint 1 (big toe joint). In contrast to the first embodiment of Figure 1 and the second embodiment of Figure 2, in the third embodiment of Figure 3, the movable element 3 is connected to the main part 14 of the shoe sole 1 by means of a plate 22 which allows the movable element 3 to be locked laterally at different extension angles with respect to the main part 14 of the sole 1, as shown in detail, for example, in Figure 3b. The plate 22 is connected to the main part 14 at one end via a first pin 23. The first pin 23 is locked, for example by screwing, from below through an opening in the main part 14 of the sole 1 into a first protuberance 25 of the plate 22. At the other end, in the area of the movable element 3, the plate 22 has a second protuberance 26 for a second pin 27. The movable part 3 of the sole 1 has a plurality of openings 24 for the second pin 27, so that the second pin 27 can pass through one of the openings 24 and be locked in the second protuberance 26. The distance between the main part 14 and the movable element 3 is adjusted in this respect by selecting the opening 24 through which the second pin 27 is locked in the second protuberance 26. Toe I is thus fixed by the movable element 3 fixed at a certain distance from toe II resting on the main part 14, the walking movement 5 (foot flexion) creating a vertical movement, by means of which a therapeutic gymnastic movement is also generated, which, thanks to the different adjustable positions, can be adjusted periodically by a physiotherapist. This is particularly advantageous when a simultaneously horizontal and vertical movement is too painful for the patient.
