Definitions
- the invention relates to the technical field of orthoses for the modification or stabilization of musculo-ligamentous and / or skeletal structures of the human or animal body, in particular for the stabilization of body joints.
- the invention provides means for preventing the migration of the hard-frame body-based orthosis.
- the solution pursued by the invention provides for fixing the orthosis with a hard-frame element to at least one anatomical protrusion of the body in a force- and form-fitting manner.
- Orthoses are therapeutically or prophylactically acting medical aids, which primarily serve the stabilization of a body joint or the musculoskeletal system of the human or animal body.
- orthoses are manufactured in different designs: so-called prophylactic orthoses are primarily used to prevent injury to the musculoskeletal system in case of above-average physical exertion, especially at the risk of overloading a body joint, especially in connection with physical activity or serious or danger-prone physical work. They are mainly by stiff Frame structures and long lever arms are marked, which protect the body joint, such as the knee joint, acting forces and moments and / or redirect to articulated structures (in the case of the knee joint, lower leg and upper teat!) So that the force on the protected Body joint is reduced.
- Re-habilitative orthoses are primarily used postoperatively and above all temporarily to maintain the surgical result and to support healing or convalescence. Re-habilitative orthoses are exposed to lower forces and moments than the prophylactic orthoses. They require a mechanically less stable or rigid construction. Their technical design can be simpler because it is related to a shorter therapeutic application time. This design simplification is opposed to a longer-term application.
- So-called functional orthoses are used both short-term postoperatively and long-term to reduce the risk of an operated body joint.
- relieving orthoses relieve the medial or lateral compartment of the body joint by virtue of their axial alignment or due to built-in restraints or pressure elements by redistributing the load, in particular the force and the surface pressure, to the respective other compartment of the articulating joint surfaces.
- orthoses are also classified according to their primary constructive features: the category of so-called "hard frame or hard shell orthoses” (English, rigid orthoses) includes primarily orthoses, which cover and cover the affected body part or joint, in particular flat with a so-called shell or hard shell (sheet metal or plastic component). Alternatively, the body part is included with a force and moment strategic framework. Since the materials used to construct the shell or frame are rigid, they must have articulated or elastic connections between the shell or frame components located above and below the joint to maintain articulation of the joint. They are typically used as prophylactic and functional orthotics.
- the category of so-called "soft-good orthoses” includes orthoses, which, like bandages, are primarily made of textile or flexible, woven, cellular or non-cellular plastics and, as a rule, the body part (for example, knee joint) comprising flat or tubular orthoses In general, they are cut from flat flexible plastics in cutting and joining processes, knitted from textile fibers with or without elastic components, or cast from moldable elastomers into molds, in some designs consisting only of pressure pads acting on the body part and fasteners.
- they are made of soft materials that are strategically reinforced and, if necessary, additionally equipped with tension straps and / or joints to perform certain anatomical / physiological functions, as a rule, they are not articulated, as they interfere with the movement of the body Body joint due be able to follow their flexibility.
- These designs are generally not classified as orthoses in the strict sense, since they are biomechanically usually only slightly effective. she are typically used as compressive and / or proprioceptive orthoses. With additional equipment on stiffening elements, they increasingly reach into the category of so-called “hybrid orthoses”.
- the category of so-called “semirigid orthoses” encompasses another group of orthoses that include both flexible, particularly textile, elements (such as a softgood orthosis) and rigid elements (such as a hard-frame orthosis), the latter being primarily functional Functional rigid elements are, in particular, side rails which may be hinged together or non-elastic textile components such as bridles.

Otherwise, the function is no longer guaranteed. In addition, an incorrectly placed orthosis can cause additional stress in the ligament and cartilage structure of a joint. A slipping or twisting of the orthosis in use, the so-called migration, should be prevented or greatly reduced in extent. In addition, a simple and secure positioning of the orthosis at the relevant physiological position (functional position) is to be made possible when creating.

- the elastomer ring can not slide off the patella, because the hole-shaped ring opening the patella on all sides includes play and the flexible textile fabric of the orthosis the elastomer ring additionally in this position (while maintaining the required movement in movement of the patella) on the knee.
- the externally applied hard-shell orthosis is in turn held in position by the oval elastomeric ring in position, which it comprises by an in turn oval-shaped opening in the frontal hard shell, pressing.
- the oval-shaped patellar opening in the hard shell can either be cut out in a simple annular manner and without three-dimensional contouring of the cutout edge or it can partially surround the radius of the elastomeric ring in a form-fitting manner.
- Form-fitting, groove-like enclosure increases the dimensional stability of the frame shell and stiffen this in addition to other (torsional) stress.
- oval elastomer ring forms the following bilateral anchoring of the orthosis:
- An improved knee orthosis is used for the prophylaxis or therapy of a patellar lateralization (dislocation tendency), in which the additional migration of the tibial head (caput tibiae) prevents the orthosis from migrating to the knee.
- the hard-frame element has a first recess according to the invention in order to receive a particularly elastomeric coupling element, which is positioned above the tibial plateau as the anatomical protrusion, in order to enable the fixation of the orthosis.
- the orthosis has at least one further recess on the same hard frame part or on another hard frame part, which enables the therapeutic fixation of the patella on the knee joint via a further elastomeric coupling element, which is arranged around the patella.
- the required contact pressure for fixing the hard-frame element via the coupling element to the tibial plateau is effected by back-curving.
