    The present invention relates to an orthosis for the dynamic correction of a misalignment of an ankle. Such orthotics usually have a mechanically articulated connection in the foot area, by means of which intra-articular corrections can be carried out on misaligned joints that are located between the rear foot and the midfoot / forefoot. These are usually dynamic foot malpositions distal to the Chopart joint, such as those that occur in club feet or sickle feet.
    In order to achieve an optimal correction of an ankle misalignment, it is necessary to adjust the articulated connection, which usually has a large number of joints, in the foot area of the orthosis very precisely to a corrected position and, if necessary, readjust it several times. For this purpose, a large number of the joints must be brought into predetermined joint angles and fixed each time in a large number of movements.
    The disadvantage of the orthotics known in the prior art for dynamic correction of foot misalignments is that the orthotic to bring about the desired corrective position (anatomically correct position) is not set individually or precisely or not quickly and easily, that is, without a large number of manipulations leaves.
    Based on this, it is therefore an object of the present invention to provide an orthosis for the dynamic correction of a misalignment of a foot, which allows an exact and uncomplicated individual setting of the desired corrective position. Furthermore, it is the object of the present invention to provide a corresponding method for the dynamic correction of a misalignment of a foot.
    The orthosis according to the invention for the dynamic correction of a malposition of an ankle joint comprises a first holding part for receiving a rear foot, a second holding part for receiving a midfoot / forefoot connected to the rear foot via the ankle. Furthermore, the orthosis according to the invention comprises an orthotic joint with an adjustment section in which a predetermined position of the first and second holding parts can be adjusted relative to one another so that the ankle can be brought into a corrective position, and a movement section which moves the first holding part with the second holding part by at least one relative to one another first axis of rotation, which essentially corresponds to an axis of rotation of the ankle, movably connects. The orthosis according to the invention thus enables a specific position of the first and second holding parts to one another to be set precisely and easily individually by means of the adjustment section and to move both holding parts to one another in this position through the movement section. Only the movement segment enables a dynamic correction of a misalignment. The invention can be used to stretch soft tissues that are too short and to mobilize joints. This relates in particular to all foot misalignments that can be corrected with a physiological screwing or rotational movement between the rear foot and forefoot.
    In an advantageous embodiment of the invention, the adjustment section of the orthotic joint has a further or more further joints and a locking device, the further joints and the locking device being coupled to one another in such a way that the predetermined position can be adjusted by means of the further joints in one adjustment movement and this predetermined position can be fixed by means of the locking device. Setting and fixing in one adjustment movement means that the holding parts of the orthosis can be brought into the predetermined position and fixed with just one movement of the hand.
    The further joints can in particular be two ball joints. The setting of the predetermined position can preferably take place steplessly and notch. This enables an individual, three-dimensional adjustment of the first and second holding parts to one another. The locking device can have a wing screw, in particular a single wing screw, for locking all other joints at the same time.
    In a further advantageous embodiment of the invention, the movement section has a hinge joint which is movable about the first axis of rotation. After the predetermined position has been fixed in the adjustment section, free mobility of the hinge joint in the movement section enables a foot malposition to be corrected dynamically.
    In addition, the orthosis according to the invention can comprise a thrust device which is set up to exert a relative torque about the first axis of rotation on the first and the second holding part and thereby bring the ankle into the corrective position. The thrust device can be able to exert a permanent torque, in particular constant or variable torque, on the first and second holding parts. As a result, the orthosis practically adjusts itself: If, in the course of the treatment, the soft tissues to be stretched progressively stretch, the pushing device maintains the tension on the soft tissues and enables the soft tissues to be stretched further. This increases the effectiveness of the orthosis.
    Furthermore, it is advantageous if the thrust device is connected to the first and the second holding part via a respective ball joint. The ball joints enable the thrust device to exert a relative torque on the holding parts along the degrees of freedom determined by the adjustment section and the movement section.
    The pushing device can in particular a gas pressure spring, a push rod, a pneumatic cylinder, a hydraulic cylinder, a coil spring, an electric motor or a combination of a push rod and an electric motor, a combination of a pneumatic cylinder and an electric motor or a combination of a hydraulic cylinder and one have electric motor. A gas pressure spring enables a constant torque over the entire range of movement of the holding parts in relation to one another.
    [0012] The first axis of rotation of the orthotic joint preferably runs essentially perpendicular to a tread surface of the orthotic. In this case, the first axis of rotation of the orthotic joint essentially corresponds to an axis of rotation of a Chopart joint.
    The first holding part and / or the second holding part preferably have an annular (circular) foot mount. If both holding parts have a ring socket, both ring sockets adjoin one another at their ring-shaped end faces in accordance with the course of the Chopart joint.
    A further advantageous embodiment of the orthosis according to the invention provides that the hinge joint divides the orthotic joint into a first joint part and a second joint part, and the first joint part is arranged on an upper side of the first holding part in the region of a longitudinal center axis, the second Joint part is arranged on an upper side of the second holding part in the area between an outer edge and the central axis running in the longitudinal direction and the thrust device is arranged in the region between the central axis running in the longitudinal direction and an inner edge. This arrangement of orthotic joint and thrust device is particularly suitable for treating club feet.
    Alternatively, the first hinge part can be arranged on an upper side of the first holding part in the area of a longitudinal center axis, the second hinge part on an upper side of the second holding part in the area between an inner edge and the longitudinal center axis and the thrust device in the area between the longitudinal center axis and an outer edge. This arrangement of orthotic joint and thrust device is particularly suitable for the therapy of buckled feet.
    In a further advantageous embodiment of the invention, the first holding part can have a lower leg part and preferably a further orthotic joint in the area of the ankle joint.
    Furthermore, it is conceivable to connect the first and the second holding part to one another in the region of the tread surface with a flexible element, preferably with a belt. This can increase the stability of the orthosis in the event of accidental toe loading.
    [0018] Orthosis according to one of the preceding claims, wherein a step cushion is arranged on the first holding part in a heel area of the orthosis. The step cushion serves as cushioning when stepping on and thus increases the comfort for the patient.
    The present invention can be used in a method for correcting a misalignment of an ankle with an orthosis as described above. In the method, the orthosis is placed on a foot to be treated, a predetermined position of the first and second holding parts is set with respect to one another by means of the adjustment section, and then the first and second holding parts are moved relative to one another in the movement section. However, such a method is not part of the present invention and is only described here as an example of an application of the orthosis according to the invention.
    An embodiment of the invention is shown in the figures and is explained in more detail with reference to the following description. In the figures described here, identical or similar elements or features are denoted by identical or similar reference symbols, so that their description need not be repeated in detail. The exemplary embodiment described below includes a large number of features and associated advantageous properties of the present invention. The features described in connection with the exemplary embodiment can, however, also represent an advantageous further development of the invention in themselves.
    1 shows an exemplary embodiment of an orthosis according to the invention in a perspective view, FIG. 2 shows the orthosis from FIG. 1 in a side view of an outside of the orthosis and FIG a perspective front view.
    Figures 1, 2 and 3 show an embodiment of an orthosis according to the invention for dynamic correction of a misalignment of a foot, such as a clubfoot misalignment.
    The orthosis has a first holding part 1 for receiving a rear foot and a second holding part 2 for receiving a midfoot / forefoot. Both holding parts 1, 2 are each designed as a ring mount and adjoin one another roughly corresponding to the course of the Chopart joint along their ring-shaped end faces. The first 1 and the second holding part 2 are connected to one another in the area of the back of the foot, that is to say on an upper side of the first 1 and second holding part 2, via an orthotic joint 3. Furthermore, the two holding parts 1, 2 are connected to one another via a thrust device 6 on an inner side of the first 1 and second holding part 2 which is located towards the center of the body. The orthotic joint 3 has an adjustment section 3a for setting a predetermined position of the holding parts 1, 2 with respect to one another, as well as a movement section 3b which enables the holding parts 1, 2 to be rotated relative to one another. The movement section 3b has a hinge joint with a joint axis 9. The holding parts 1 and 2 are thus rotatable about the axis 9 relative to one another. The hinge joint of the movement section 3b divides the orthotic joint 3 into a first joint part 3b1 and a second joint part 3b2, the first joint part 3b1 being arranged on an upper side of the first holding part 1 in the area of a central axis 10 running in the longitudinal direction of the foot and the second joint part 3b2 being Adjustment section 3a comprises and is arranged on an upper side of the second holding part 2 in the area between an outer edge and the central axis 10 running in the longitudinal direction. The adjustment section 3 a has two ball joints 4 a and 4 b and a wing screw as a locking device 5. In order to set the predetermined position of the holding parts relative to one another, the setting section 3a can be individually aligned three-dimensionally with a handle on the basis of the ball joints 4a and 4b and fixed by means of the wing screw. The thrust device 6 is arranged in the area between the central axis 10 running in the longitudinal direction and an inner edge of the first and second holding parts 1, 2. The thrust device 6 has a gas pressure spring 6a which is arranged essentially in the longitudinal direction of the foot and which is connected to the first holding part 1 and the second holding part 2 via a ball joint 7a, 7b. The orthosis shown in FIGS. 1 and 2 also has a lower leg part 11 connected to the ring mount of the first holding part 1 via a further orthotic joint 12 in the area of the ankle joint. In the foot area and in the area of the ankle joint, the orthosis also has a soft-wall liner 13, which is arranged within the first 1 and second holding part 2. A step cushion 8 is also arranged on an underside of the first holding part 1.
    When using the orthosis to correct a clubfoot misalignment, the foot is first brought from a misalignment into a desired corrected position by aligning the holding parts 1, 2 with one another. For this purpose, a predetermined position of the holding parts 1, 2 with respect to one another is set three-dimensionally and continuously individually by means of the ball joints 4a and 4b, and these are fixed by means of the locking device 5. In addition, the gas pressure spring 6a of the thrust device 6 is set so that it exerts a desired torque on the holding parts 1 and 2 for stretching the hinged ligaments in the area of the Chopart joint. Without the pushing device 6, the holding parts 1, 2 could now still rotate about the axis 9 relative to one another within the predetermined position. However, the thrust device 6 now exerts a relative torque on the holding parts 1, 2 around the joint axis 9 and prevents the forefoot from kinking inward.
    Figure 3 shows the operation of the thrust device 6 of the orthosis according to the invention according to the embodiment of Figures 1 and 2. (a) shows the orthosis with the two holding parts 1 and 2 in the predetermined position and a tensioned gas pressure spring 6a of the thrust device 6. The The gas pressure spring 6a exerts a strong torque on the holding parts 1 and 2 with respect to one another. As a result, the joint ligaments in the area of the Chopart joint are greatly stretched, which is intended to correct the tendency of the metatarsus / forefoot to bend inward. (b) shows the orthosis with a less tensioned gas pressure spring 6a. Here, the joint ligaments are only stretched very slightly in order to minimize stretching pain.
    The orthosis can be used for the following indications (without claim to completeness): HSMN - arches of the plantar aponeurosis, hereditary motor and sensory neuropathy, rebellious clubfeet, avoidance of postoperative adhesions and restricted movement, AMC - promotion of mobility in the foot structure (both conservative and post-operative) and preoperative stretch treatment for shortened soft tissues.
