Abstract

L'orthèse comprend une semelle(1) sur laquelle sont fixés des éléments façonnés : talonnettes (supérieure(2) inférieure5), anneau talonnier(3), hémicoupole interne(4). Elle est revêtue de tissu néoprène. L'orthèse podologique modifie le déroulement naturel coordonnant les actions des éléments constitutifs (os, ligaments, muscles) du pied: lors de la déformation statique elle diminue l'écrasement et l'allongement excessif des arches, lors de la déformation dynamique, elle évite la contraction excessive et douloureuse des tendeurs plantaires. Ce conditionnement permanent des positions du pied détourne les points d'application des tendeurs et faisceaux musculaires vers des zones moins vulnérables à la survenue du phénomène inflammatoire cause de l'apparition puis de la pousse de l'épine calcanéenne. Ces aspects purement mécaniques sont complétés par l'imprégnation du revêtement néoprène par un anti-inflammatoire dont les effets, de nature thérapeutique, lui confère un caractère biactif.The orthosis comprises a sole (1) on which are fixed shaped elements: heelpieces (upper (2) lower5), heel ring (3), inner hemicyloid (4). It is covered with neoprene fabric. The podological orthosis modifies the natural course coordinating the actions of the constituent elements (bones, ligaments, muscles) of the foot: during the static deformation it reduces the crushing and the excessive elongation of the arches, during the dynamic deformation, it avoids the excessive and painful contraction of the plantar tendons. This permanent conditioning of the foot positions diverts the points of application of the tendons and muscle bundles to areas less vulnerable to the occurrence of the inflammatory phenomenon due to the appearance and growth of the calcaneal spine. These purely mechanical aspects are completed by the impregnation of the neoprene coating with an anti-inflammatory whose effects, of a therapeutic nature, gives it a biactive character.

Description

- 1 - La présente invention concerne ce qu'il est désormais convenu de nommer orthèse podologique. Il s'agit d'une évolution du terme générique semelle utilisé en podologie dans des acceptions généralement correctrices de postures fonctionnellement défavorables ou d'amélioration du confort, vers une conception curative dans une pathologie douloureuse et invalidante : l'épine calcanéenne ou épine de Lenoir. Il est connu, pour soulager les douleurs inflammatoires liées à la pathologie de l'épine calcanéenne, de recourir à des talonnettes, trouées en leur centre, qui évitent un appui direct sur la surface endolorie. Les résultats obtenus ne sont pas encore très probants. L'invention a pour but de combiner l'emploi d'éléments de façonnage classiquement utilisés dans l'exercice de la podologie en vue de réaliser une orthèse composite de maintien du pied dans une posture antalgique définie, avec un dispositif de répartition des charges du talon hors des zones douloureuses en vue d'éviter la survenue du phénomène inflammatoire du fascia plantaire dont l'enclenchement provoque, in fine, la pousse d'une épine osseuse horizontale : l'épine calcanéenne. Avant de décrire les avantages et caractéristiques de l'orthèse selon l'invention, il convient de présenter l'anatomie sommaire du pied, considérée comme connue, ainsi que le vocabulaire y afférent. L'architecture de la plante des pieds peut, selon les bons auteurs, être assimilée à une voute soutenue par trois arches. Deux sont dans l'axe du pied, l'une dite externe, l'autre dite interne. Elles sont composées, du talon vers le gros orteil, par l'assemblage articulé d'un système osseux : calcanéus, thalus, naviculaire, cunéiformes. La troisième arche, transversale, complète, à l'avant du pied, les arches longitudinales. Elle est constituée par le réseau des os métatarsiens. Un ensemble complexe de nombreux ligaments assure la cohésion et les courbures des arches, des faisceaux musculaires forment les 3031036 - 2 - tendeurs actifs assurant l'élasticité des arches à l'occasion notamment de la marche. Sous charge, chaque arche s'écrase et s'allonge dans des fourchettes de valeurs propres à chaque individu, et reprend sa courbure initiale entre 5 chaque pas. Au fil des ans ou pour des causes pathologiques cette voute plantaire voit son système d'arches articulées, mobiles, élastiques, assemblées par des muscles et des tendeurs perdre ses capacités de retour à l'état de voutes arquées provoquant des déformations permanentes à l'origine de diverses altérations chroniques dont celle dite épine calcanéenne.The present invention relates to what is now known as podological orthosis. It is an evolution of the generic term insole used in podiatry in generally corrective meanings of functionally unfavorable postures or comfort improvement, towards a curative conception in a painful and disabling pathology: the calcaneal spine or Lenoir's spine . It is known, to relieve the inflammatory pain related to the pathology of the calcaneal spur, to resort to heelettes, perforated in their center, which avoid a direct support on the sore surface. The results obtained are not yet very convincing. The aim of the invention is to combine the use of shaping elements conventionally used in the practice of podiatry with a view to producing a composite orthosis for maintaining the foot in a defined analgesic posture, with a device for distributing the loads of the foot. heel out of the painful zones in order to avoid the occurrence of the inflammatory phenomenon of the plantar fascia whose engagement causes, finally, the growth of a horizontal bony spine: the calcaneal spine. Before describing the advantages and characteristics of the orthosis according to the invention, it is necessary to present the basic anatomy of the foot, considered as known, as well as the related vocabulary. The architecture of the soles of the feet can, according to the good authors, be likened to a vault supported by three arches. Two are in the axis of the foot, the so-called external, the so-called internal. They are composed, from the heel to the big toe, by the articulated assembly of a bone system: calcaneus, thalus, navicular, cuneiform. The third arch, transverse, completes, at the front of the foot, the longitudinal arches. It is constituted by the network of metatarsal bones. A complex set of numerous ligaments ensures the cohesion and curvature of the arches, muscle bundles form the active tensioners ensuring the elasticity of the arches especially during walking. Under load, each arch crashes and extends into ranges of values specific to each individual, and resumes its initial curvature between each step. Over the years or for pathological reasons this plantar arch sees its system of arches articulated, mobile, elastic, assembled by muscles and tensioners to lose its ability to return to the state of arcuate vaults causing permanent deformations to the origin of various chronic alterations including that called calcaneal spine.

10 Pour compenser ces déformations la présente invention agit d'une part sur les appuis par une combinaison de calles, de rehausseurs, de limiteurs d'affaissement pour conditionner en permanence le positionnement du pied, d'autre part sur la dynamique des tendeurs et faisceaux musculaires pour détourner les points d'application de leurs efforts vers des zones moins 15 vulnérables à l'entretien du phénomène inflammatoire cause de l'apparition puis de la pousse de l'épine calcanéenne. L'orthèse podologique, selon l'invention, accompagne et modifie le déroulement naturel coordonnant les actions des composants (os, ligaments, muscles) du pied : d'une part, lors de la déformation statique elle diminue 20 l'écrasement et l'allongement excessifs des arches, d'autre part, lors de la déformation dynamique, elle évite la contraction excessive et douloureuse des tendeurs plantaires. L'orthèse podologique selon l'invention ressortira plus clairement de la description qui suit en se référant au dessin annexé qui représente un mode 25 de réalisation non limitatif et que la partie semelle peut être entière ou partielle( demie ou trois quart de la surface du pied ) Dans le dessin annexé : 3031036 - 3 - La figure 1 représente une vue de dessus de l'orthèse podologique selon l'invention, La figure test une vue de dessous correspondant à la figure 1, La figure 3 est une vue latérale interne correspondant aux figures 1 et 2, 5 La figure 4 est une vue latérale externe correspondant aux figures 1 et 2, L'orthèse podologique comprend une semelle ( 1) ayant une face supérieure et une face inférieure auxquelles sont fixés des éléments façonnés : talonnette supérieure (2 ), anneau talonnier ( 3 ), hémicoupole 10 interne (4) , talonnette inférieure ( 5 ) . Cet ensemble constitue une architecture réactive conçue pour le logement et le maintien du pied dans une position de décharge apte à modifier les contraintes et efforts des muscles et tendeurs des arches de la voutes plantaire, susceptible d'éviter l'étirement du tendon et de son aponévrose au point d'insertion sur le calcanéus siège d'une 15 épine calcanéenne. La talonnette inférieure (5), en caoutchouc cellulaire, rehausse le talon en vue de détendre le tendon d'Achille et d'amortir les chocs de contact du talon au sol. Elle comporte, à mi- épaisseur du matériau deux évidements (6) de 2,5 millimètres de diamètre dont le but est de répartir la charge autour de la zone 20 sensible du talon au droit de l'épine calcanéenne. L'anneau talonnier (3), en mousse compressible à 60 %, d'une épaisseur de 6 à 8 millimètres, maintient et stabilise l'arrière pied en position favorable à la limitation de l'affaissement des arches plantaires longitudinales. Ses limites, adaptées à chaque individu, se situent en arrière de la tête du 5éme 25 métatarsien, en regard de l'interligne naviculo-cunéen, sa largeur varie entre 10 et 15 millimètres, rétrécie dans sa partie postéro interne et latérale externe, renflée au niveau sous naviculaire. 3031036 -4- L'hémicoupole interne (4), en mousse compressible à 60 %, d'une hauteur d'environ 8 millimètres, évite l'allongement et l'abaissement de l'arche interne entrainant une décontraction des tendeurs plantaires internes et une amélioration de la stabilité du pied et plus généralement le confort du média 5 pied. Son positionnement, adapté à chaque individu, se situe depuis l'arrière de la tête du premier métatarsien jusqu'au tiers de la longueur du pied, elle est de forme convexe le sommet étant sous naviculaire. La talonnette supérieure (2), en mousse rehausse de 6 millimètres le talon en vue de détendre le tendon d'Achille ainsi que le muscle gastrocnémien.To compensate for these deformations, the present invention acts on the one hand on the supports by a combination of calluses, boosters, slump limiters to permanently condition the positioning of the foot, on the other hand on the dynamics of the tensioners and bundles. muscle to divert the points of application of their efforts to areas less vulnerable to maintenance of the inflammatory phenomenon cause the appearance and growth of the calcaneal spine. The podological orthosis, according to the invention, accompanies and modifies the natural course coordinating the actions of the components (bones, ligaments, muscles) of the foot: on the one hand, during the static deformation it reduces crushing and excessive elongation of the arches, on the other hand, during dynamic deformation, it avoids the excessive and painful contraction of the plantar tendons. The podological orthosis according to the invention will emerge more clearly from the following description with reference to the appended drawing which represents a nonlimiting embodiment and that the sole portion may be integral or partial (half or three quarter of the surface of the In the accompanying drawing: FIG. 1 represents a top view of the podological orthosis according to the invention, FIG. 1 is a bottom view corresponding to FIG. 1; FIG. 3 is an internal lateral view. FIG. FIG. 4 is an external lateral view corresponding to FIGS. 1 and 2. The podological orthosis comprises a sole (1) having an upper face and a lower face to which shaped elements are attached: upper heel (2), heel ring (3), internal hemicoupole (4), lower heel (5). This set is a reactive architecture designed for the housing and the maintenance of the foot in a discharge position able to modify the stresses and efforts of the muscles and tendons arches of the arches of the plantar, likely to avoid the stretching of the tendon and its fascia at the point of insertion on the calcaneus seat of a calcaneal spine. The bottom heel (5), made of cellular rubber, enhances the heel to relax the Achilles tendon and to dampen the impact of contact of the heel to the ground. It comprises, at half the thickness of the material, two recesses (6) of 2.5 millimeters in diameter, the purpose of which is to distribute the load around the sensitive zone of the heel to the right of the calcaneal spine. The heel ring (3), made of 60% compressible foam, with a thickness of 6 to 8 millimeters, maintains and stabilizes the rear foot in a position favorable to the limitation of the sagging of the longitudinal arch. Its limits, adapted to each individual, lie behind the head of the 5th metatarsal, opposite the navicular-cunean spacing, its width varies between 10 and 15 millimeters, narrowed in its posterior internal and external lateral part, swollen at the sub-navicular level. The inner hemicupolus (4), 60% compressible foam, a height of about 8 millimeters, avoids the lengthening and lowering of the internal arch causing a relaxation of the internal plantar tendons and an improvement of the stability of the foot and more generally the comfort of the media 5 foot. Its positioning, adapted to each individual, is located from the back of the head of the first metatarsal to the third of the length of the foot, it is of convex form the vertex being under navicular. The upper heel (2), foam enhances the heel 6 millimeters to relax the Achilles tendon and the gastrocnemius muscle.

10 L'orthèse podologique est revêtue d'un tissu en néoprène bactériostatique (non représenté) de 2 millimètres d'épaisseur qui améliore te confort. Le revêtement peut être aussi imprégné d'un produit anti-inflammatoire permettant ainsi de compléter les actions purement mécaniques de l'orthèse par des effets de nature thérapeutique pour lui conférer un caractère biactif.The podological orthosis is coated with a bacteriostatic neoprene tissue (not shown) 2 millimeters thick which improves comfort. The coating may also be impregnated with an anti-inflammatory product thus making it possible to supplement the purely mechanical actions of the orthosis with effects of a therapeutic nature to confer a biactive character.
