Definitions

  • the invention relates to an orthosis with a foot part and a lower leg part, both of which are designed for attachment to the foot or lower leg of a patient and are connected to one another by means of a spring element which is curved in the rest position, the spring element being guided exclusively anteriorly and anteriorly with the lower leg part and dorsally with the Foot part is connected.
  • Such orthoses which serve as separate ankle orthoses or part of a full-leg orthosis for supporting the ankle, are known in numerous embodiments. They form an alternative to the orthoses, in which the foot part and lower leg part are connected to one another at a height of the ankle area via a joint restricted in its movement.
  • the generic spring-elastic orthoses offer clear advantages for a more dynamic and physiological gait pattern.
  • Variants of this design provide for posterior guidance of the spring in the lower leg area, which is then guided laterally from the foot to approximately the center of the foot.
  • the invention is therefore based on the object of designing an orthosis of the type mentioned at the outset in such a way that an improved gait pattern can be achieved.
  • the anterior arrangement of the spring element thus ensures good adaptability of the orthosis to the natural movement of the foot and lower leg while providing the required support function.
  • the orthosis according to the invention enables elastic plantar flexion, so that a soft, cushioned heel strike is possible.
  • the spring element is preferably designed in the form of a narrow strip and therefore has leaf spring properties which are regularly sought for a dynamic ankle orthosis.
  • the strip can be bent slightly elastically perpendicular to the spring plane, whereas bending in the spring plane itself is practically impossible, so that the regularly desired lateral support function is guaranteed.
  • the lower leg part and foot part are preferably designed in the shape of a shell in order to enable the orthosis to be conveniently attached to the lower leg and foot of the patient.
  • the foot section and lower leg section e.g. after plaster cast, to be made.
  • the foot section with an exchangeable footbed, which can also be made individually.
  • a variant is particularly preferred in which the shell-shaped foot part or lower leg part is designed to be dimensionally stable, on the one hand to ensure simple attachment to the foot or lower leg and on the other hand to be able to ensure that the forces acting on the foot when walking are complete and secure be transferred to the foot part and thus to the spring element and via the lower leg part to the lower leg.
  • the use of the adapter between the spring and the lower leg part can be used to compensate for an incongruity of the spring kinematics with the ankle movement by means of an approved small relative movement (displacement).
  • a spring preload must be applied so that the lower leg part is lifted proximally.
  • the lower leg part has a fastening means for fastening to a lower leg, which is provided with a textile that allows a limited displacement to the lower leg part.
  • the text til is flexible, but inelastic in order to limit the displaceability in a defined way.
  • a spacer fabric with which the fastening part of the lower leg part rests on the lower leg is particularly suitable. The spacer fabric allows a limited shear movement of the surface lying on the lower leg part to the surface of the knitted fabric lying on the fastening means, thereby ensuring a certain relative displaceability in the longitudinal direction of the lower leg.
  • a releasable, displaceable connection can be used to influence the sagittal ankle joint position. In the selected ankle joint position is then fixed in the connection mentioned.
  • the foot part and the lower leg part are preferably rigidly attached to the spring element, in particular screwed, clamped or positively fixed, so that neither rotation relative to the spring element nor one
  • Displacement relative to the spring element is possible if a rigid coupling is desired. While in principle the displaceability or rotatability of the foot part or lower leg part to the spring element is provided for an adjustment and adjustment process to the lower leg or the foot, such relocability relative to the spring element is prevented during use by the torque-rigid fixing. This can fix the
  • Ankle joint can be achieved in a certain position, while at the same time mobility of the ankle joint is maintained due to the flexibility of the spring element.
  • the single figure shows a bowl-shaped lower leg part 1 and a bowl-shaped foot part 2.
  • Fastening means for fixing to the lower leg and foot of the patient are not shown on these parts. These can be formed, for example, by tapes provided with Velcro fasteners.
  • the lower leg part 1 is arranged at a distance from the foot part 2 and connected via a spring element 3 in the form of a strip-shaped leaf spring.
  • an adapter 4 is indicated both on the lower leg part 1 and an adapter 5 on the foot part 2, which are adapted to a bowl-shaped shape of the lower leg part 1 or the foot part 2 and serve to fasten the ends of the strip-shaped spring element 3.
  • the ends of the spring element 3 thus protrude far into the lower leg part 1 and the foot part 2.
  • the spring element 3 has a bend which corresponds to the angle between the instep of a foot and the shin of the patient.
  • the strip-shaped spring element 3 can be formed from any suitable spring material, in particular from spring steel or from a suitable fiber-reinforced plastic.
  • screws 6 are attached from the outside to the lower leg part 1 or the foot part 2, which preferably protrude through slot holes in the spring element 3, so that the length of the lower leg part 1 or the foot part 2 can be adjusted relative to the spring element 3 cause.
  • the foot part 2 and the lower leg part 1 can be made from dimensionally stable materials, such as metal, plastic or composite materials. Are preferred such dimensionally stable foot parts 2 and lower leg parts 1 made from an impression. Alternatively, adaptability can be made possible by padding on the side of the foot part 2 or lower leg part 1 facing the foot or lower leg. Due to the dimensionally stable design of the foot part 2 and the lower leg part 1 and the rigid coupling with the spring element 3, it is possible to move the foot about an axis in a frontal plane against the spring force of the spring element 3, while not pivoting about an axis in a sagittal plane is possible.
  • the orthosis according to the invention thus stabilizes the foot on the one hand, so that even if the foot and lower leg are paralyzed, forces acting on the foot can be transmitted to the lower leg when walking, on the other hand the resilient coupling of the dimensionally stable foot and lower leg parts 2, 1 a certain mobility of the ankle around an axis in a frontal plane enables a movement sequence that approximates the natural gait.
  • the stabilization is made possible by a torque-rigid coupling between the spring part 3 and the foot and lower leg part 2, 1.

Abstract

L'invention concerne une orthèse comportant une partie de pied (2) et une partie de mollet (1) conçues pour être fixées sur le pied ou le mollet d'un patient, connectées par l'intermédiaire d'un élément ressort (3) courbé en position de repos. L'élément ressort (3) est placé de façon exclusivement antérieure et connecté de façon antérieure à la partie de mollet (1) et de façon dorsale à la partie de pied (2). L'orthèse selon l'invention permet une marche dynamique et physiologique ainsi qu'un appui doux du talon du fait que l'élément ressort (3) est exclusivement monté de façon antérieure et connecté de façon antérieure à la partie de mollet (1) et de façon dorsale à la partie de pied (2).
