Abstract

The orthosis (1A) has two ring clamps (3,4) assigned to limbs and a bar (5), which connects both the ring clamps with one another. The ring clamps form as guide openings. A continuous recess (18) is provided in the area of the ring clamps. A ring clamp is divided into a left and right wing (17). The orthosis is adapted in an unchangeable form by plastic deformation on joint (13') under normal operating conditions.

Description

invention concerns a thumb orthosis with an upper and a lower one Ringbügel and a bridge, the bridge with each of the two ring hoops an annular opening for the insertion of the thumb forms and the thumb orthosis by the interaction of both ring straps on the hand outer surface associated outer surface of the thumb with the web on the palm associated inner surface of the thumb can be fixed in an end position on the metacarpophalangeal joint, wherein both ring straps form a joint skirt, which the metacarpophalangeal joint on the palm of the hand encloses.

Thumb orthoses are known in the art. They serve to relieve the Thumb saddle joint and for stabilization of the metacarpophalangeal joint, wherein in bone or joint diseases of the thumb improves the stabilization and support of certain joints can be.

Thumb orthoses especially in Rhiz arthrosis, instabilities of Of the metacarpophalangeal joint or after operations to restore the correct joint position or to reduce functional discomfort used in joint deformity in the thumb saddle joint.

at Rhiz arthrosis is degenerative processes on the thumb saddle, the cause being in a weakening of the ligaments is suspected. Rhiz osteoarthritis manifests itself Subluxation (not complete sprain) of the metacarpal I proximal due to instability, compensatory hyperextension (compensatory hyperextension), more limited Abduction (excessive limb movement), excessive Flexion (kinking) of the thumb base joint during the gripping process as well complicated extension and opposition.

The The prior art thumb orthosis has a ring on it a top and a bottom. The thumb gets through the ring plugged. The ring is pushed over the thumb, that the top on the outside of the hand associated outer surface of the thumb rests. The underside then lies on the palm of the hand Inside surface of the thumb. On the top and bottom eyelets are provided, in which a fastening strap threaded looped is, with the wrist is inserted into the loop and the ring by tightening the fastening strap on the wrist stretched and fastened.

The The thumb orthosis of the prior art has the disadvantage that the Thumb in his mobility is severely restricted. He is forced into a constantly splayed stance. In This attitude is the function of the thumb when gripping exclusively limited to a so-called Spitzgriff, in which only the thumb tip involved in the gripping function of the hand is what causes an unfamiliar burden of joint involvement and associated pain can result. On the other hand has proved that the thumb orthosis of the prior art only suitable for spreading the thumb. A support or stabilization of the diseased joints is not effected.

Furthermore It has been found that with a handle with applied thumb orthosis in the prior art, in which the thumb over spread out at a certain angle, the thumb base joint without the forced diversion. The thumb saddle joint gets unprotected in his morbid deformity back and is charged in the malposition, although the thumb orthosis will be carried.

Of Further, the fastening tape gets dirty quickly, as it is in the area of the palm or thumb bale directly on the gripping surface the hand rests and thus in almost all manual activities can come into contact with polluting substances. This will the fastening tape quickly unhygienic and unsightly.

From the DE 20 2006 001 385.7 a thumb orthosis is known with an upper and a lower ring hoop and a web, wherein the web with each of the two hoop an annular opening for insertion of the thumb forms and the thumb orthosis by the interaction of both hoops on the outer surface of the outer surface associated with the Thumb can be fixed with the bridge on the inner surface of the thumb assigned to the palm of the hand in an end position on the metacarpophalangeal joint, wherein both annular straps form a joint surround, which surrounds the metacarpophalangeal joint on the palm of the hand.

At this in itself very beneficial acting thumb orthosis has proved disadvantageous that the production of each thumb orthosis a standard production method is not optimal is accessible. The thumb orthosis needs for each individual use can be made as a single piece. Around the dimensions and individual ergonomic features of the hand beyond that are elaborate Adjustment work required, which special equipment require. The manufacture as well as the fitting to the hand are therefore very time consuming and costly.

The invention is based on the object overcome the disadvantages of the prior art, in particular to provide an improved thumb orthosis, with which a permanent stabilization of the thumb and a relief of diseased joints ensures and can be dispensed with tape fasteners, the thumb orthosis for mass production and for simple adjustment is prepared.

A Solution is provided by having at least one Ring bow a longitudinal through interruption having the ring hoop in a left and a right wing divides, and that the ring hoop through plastic deformation of at least one wing on the thumb is customizable.

With the thumb orthosis according to the invention is thus a joint socket of the thumb base joint on the outer surface of the thumb possible, whereby the thumb Grundgelenk by the bridge, which rests on the inner surface of the thumb, is held in a slightly bent position. This will do that Thumb ground joint pressed in the physiologically correct position and the position of the thumb saddle joint exclusively Corrected under load by gripping that in turn is pressed into the physiologically correct position. The The thumb saddle joint lies outside the thumb orthosis and only according to the distribution of forces between the thumb orthosis or the thumb base joint supported thereby and the wrist acted upon. This is the base of the thumb held with the orthosis in a slight bend, which prevents that it gets into an overexpansion, which can be associated with pain.

By doing at least one ring hoop one in the longitudinal direction continuous interruption, it is achieved that the thumb orthoses can be made in mass production. Longitudinal throughout is to be understood that the interruption the Ringbügel so divides that two wings arise, it does not depend on the form or design of the interruption, but just that both wings are relative to each other be bent apart or pressed together. With the two wings remains the shape of the ring hoop open and can be adapted to the patient.

According to the invention different sizes with the embodiment can be produced as a blank. Individual adjustments can on the patient directly by changes in the wings be made. The adaptation to the ergonomic requirements are thus easy to implement, with conventional small tools can be used for material processing. The advantageous subdivision of the hoop in a left and a right wing allows for both an adaptation in circumference and diameter by grinding to the mutually associated End faces and then ßendem compression the wing. In addition, there is also an adaptation possible, with the wings pressed apart be, with the gap of the interruption increases becomes. If the gap for an optimal fit would be too large, can to the next basic size of the blank be resorted to, which would then be narrowed. Thus, with a small number of basic sizes the blanks can be achieved optimal care of the patient.

According to the invention provided that both ring straps to the thumb size are customizable. Possible embodiments can also be achieve that only the upper or lower ring hoop has an interruption.

The Position of the wings to each other according to the invention at the adaptation achieved by plastic deformation, d. H. that this Material is deformed by the application of deformation force and then Under normal conditions of use unchangeable in shape remains, so a deformable for the thumb joint Body forms.

Consequently the ring hoops are about a simple change at least one of the two wings adaptable to the thumb. It has been proven that the interruption no disturbance wearing comfort, but on the contrary the gap in addition to the constructive open design of this thumb orthosis acts as a filigree recess, which prevents moisture by sweat or other liquids permanently between skin and orthotic material jams.

The Wings have the full effect of a closed Ringbügel and press the thumb joint as an abutment of the bridge in the ergonomically correct position. The bridge of the thumb orthosis, which at the base of the thumb at the inner surface of the thumb is arranged, press this outward into the so-called physiological position. This ensures that the thumb saddle joint is in turn positively corrected, bringing a Relief of the thumb saddle joint and a reduction or Avoidance of pain goes along.

Thus, with the thumb orthosis according to the invention, the advantages of a ligament-less thumb joint support are realized, whereby a correction of malpositions of the thumb base joint and thumb saddle joint can be achieved without permanently applying the hand or the thumb in the unloaded state to keep in a splayed position. In this case, a buckling of the thumb base joint and the associated painful hyperextension of the thumb saddle joint is prevented.

About that In addition, the thumb around the bridge without much or no noticeable restrictions are bowed down and stays in place advantageously complete and largely painless used. The thumb can be fully inserted when gripping with the orthosis without disability on the thumb can remain and is held independently on the thumb, d. H. The orthosis does not slip off the thumb even without a strap from.

There The thumb orthosis can be worn incessantly a progression of degenerative processes of transformation in the musculoskeletal system of the Thumb counteracted. This allows that both the symptoms such as pain are alleviated can as well as a decay process at the joints and bone is allowed with which malformations can be regressed.

In Advantageously, with the inventive Thumb orthosis provided an improvement bringing the thumb orthosis for making and adjusting optimally prepared. Thus it is possible, cost-effective and to ensure fast patient care and on changes in the physical characteristics of the to be able to enter sick joints.

advantageous Embodiments of the invention Thumb orthosis are proposed by the subclaims. It is provided that the interruption substantially along the Plug insertion of the thumb runs, so essentially parallel to the thumb itself. The insertion direction determines also essentially the longitudinal direction of the entire orthotic body.

A alternative embodiment is provided that the interruption over the ring hoop spiral runs around the thumb axis. Each wing is enough with its tip until the other's connection at the dock.

At a further embodiment according to the Invention is provided that at least one wing hinged hinged on the bridge and at least one closure means for having the lock. The closure means preferably at least a buckle or a loop closure or latching means, with which the respective wing can be locked in a fixed end position on the thumb.

A further embodiment of the invention Thumb orthosis is provided by the lower ring hoop an expiring to the thumb saddle joint support surface having. The support surface is in an advantageous Widened way starting from the bridge, so that the thumb stump and the edge of the hand or thumb bale is enclosed by the orthosis is. It is envisaged that the support surface at least to the thumb inner surface is open, so that the Thumb in gripping direction around the bridge diffractable and thus complete remains movable. At higher grade of joint disease can the dimensions of the support surface are larger, while in mild diseases a small support surface sufficient.

Of Further, an embodiment is provided thereby that the web at least partially between the upper ring hoop and the lower ring hoop as widened integrated Support rail is formed. The support rail runs thereby from the upper ring iron, whereby The upper ring strap abuts the thumb distally. Distal means in this context, hearty on the thumb, so the thumbnail out. In addition, the ring hoop encloses the thumb on the outer surface of the thumb.

From The invention also includes an embodiment, in which the support rail to the end of the lower Ringbügel runs. According to the invention provided that the support rail the handinneren The edge of the thumb encloses, d. H. the support rail abuts the side of the hand, which faces the body is.

In Advantageously, this is achieved in that the thumb base joint on the hand or thumb ball is splinted. The support effect The thumb orthosis is thus improved as the support surface further extends over the adjacent support rail. In addition, the thumb gets a further support on the inner thumb margin, leading to further stabilization of the musculoskeletal system of the thumb. At higher Degree of joint disease can be the sizing of the support rail bigger, while light Diseases a short splint is sufficient.

there is provided that the support surface and the support rail are integrally molded into each other, so that an ergonomic Attachment to the thumb is possible.

For this has proven to be particularly beneficial that the thumb orthosis is integrally formed.

Alternatively, the invention provides that the thumb orthosis is multi-part and joint having means on a ring hoop in the region of the web, whereby the ring hoop is adjustable relative to the web, and that the hoop comprises locking means for locking in the closed state. Such a configuration of the orthosis can be used in the clinical picture of a so-called 90/90 thumb, which is also known as a shoemaker's thumb. In this case, a form has been found in which the thumb orthosis has an ergonomically optimal contact surface in the closed state. The thumb orthosis has for this purpose hinge means and at least one clasp. When closed, the ring clamps are held together by closing. When the clasps are opened, the earloops can be opened so that the thumb has a larger opening cross-section as it is inserted, as is required, for example, with a 90/90 thumb (shoemaker's thumb).

According to the invention provided that movable to a bridge and a ring hoop are. In this embodiment, the two ring hoops fixed to each other and the hinge means are between the bridge and the remaining orthosis arranged.

alternative can the hinge means according to the invention be arranged a ring hoop. In this preferred Embodiment is provided that the web in one piece is connected to at least one ring hoop, preferably with the upper ring hoop. The other ring hoop In contrast, is held correspondingly hinged. there the bridge forms together with the ring hoop a body and the other ring hoop is on each side with hinges attached to this body. Closure means sit preferably on the side of the thumb orthosis. These are conventional Close applicable, which is known from jewelery production are. Alternatively, eyelet closures or Plug-in closures can be used.

According to the invention further provided that the ring hoop to ensure the unilateral thumb mobility open thumb inside open are. The thumb orthosis is designed so that the bridge the inner surface of the thumb is ergonomically favorable molded surrounds. The ring hoops extend from the bridge starting outside around the thumb, being outwards widen to flat and on both sides to the jetty narrow. This is the upper ring bow distal and the Lower ring hanger proximal to the base of the thumb. Standing there the through the hoop and the bridge for the thumb holes formed levels through which the thumb is inserted into the orthosis becomes, essentially v-shaped and cut in the area of the footbridge.

In Advantageously, it is provided that the thumb orthosis or at least individual components made of plastically deformable material consist, preferably made of plastic, metal or composite material. Thus, thumb orthoses can be produced, which are chemically resistant and thus easy to clean. It is beyond that possible to make the thumb orthosis with materials, which have high temperature and dimensional stability. It is also a thumb orthosis of material of the invention includes, which has dirt-repellent properties. there Ensures that the wings with simple Means is customizable.

Of Furthermore, it is provided that at least areal areas individual components of the thumb orthosis filigree recesses or have ergonomic formations.

It also gives better ventilation reached under the thumb orthosis.

The Invention will be described below with reference to the drawings of exemplary embodiments the thumb orthosis explained. Show it

1 the inventive thumb orthosis in the intended carrying position on the thumb;

2 a perspective top view of the inventive thumb orthosis;

1 shows the inventive thumb orthosis 1 in the intended carrying position on the thumb 2 , The thumb orthosis 1 has an upper ring hoop 3 , a lower ring hoop 4 as well as a jetty 5 on. As in 2 Visible forms the footbridge 5 with each of the two ring straps 3 . 4 an annular opening 6 . 7 through which the thumb 2 when putting on the thumb orthosis 1 can be inserted one after the other.

The ring hoops 3 . 4 lie in the in 1 illustrated, applied state of the orthosis on the outer surface 8th of the thumb 2 , which is the palm of the hand 9 is assigned while the bridge 5 on the opposite inner surface 10 of the thumb 2 which is the palm of your hand 11 assigned. The jetty 5 is in 1 from the thumb 2 hidden and therefore not visible.

The thumb orthosis 1 sits by the interaction of the two ring hoops 3 . 4 on the outside surface 8th with the jetty 5 on the inner surface 10 of the thumb 2 in the carrying position. The carrying position is thereby by the end position of the web 5 in the crook of the thumb 2 between hand 12 and Dau men 2 at the base of the thumb 13 established.

The thumb orthosis 1 is in the carrying position thus at the thumb base joint 13 fixed, with the two ring hoops 3 . 4 a joint mount 14 form the the thumb ground joint 13 on the outside surface 8th of the thumb 2 includes. The thumb ground joint 13 thus remains at an inward to the inner surface 10 of the thumb 2 directed flexion freely and completely mobile. Outwardly, the buckling of the thumb base joint 13 forming limbs by the rigid arrangement of the ring hoop 3 . 4 in relation to the bridge 5 prevents between which the thumb 2 rests.

Advantageously, with the thumb orthosis 1 thus a supporting function of the thumb basic joint 13 ensured without the thumb orthosis 1 from the thumb ground joint 13 and therefore also from the thumb 2 can slip, which can be dispensed with fastening straps.

A particular advantage of the invention is that the entire hand 12 graspable remains. Here are the the thumb base joint 13 forming limbs by the rigid arrangement of the ring hoop 3 . 4 held in a slight bend, so that when gripping the hand 12 the at the thumb saddle joint 15 effective force angle always remains sufficiently small and thus the thumb saddle joint 15 forming limbs also remain in a slight bend. This is the thumb saddle joint 15 stabilized.

The supporting function of the thumb orthosis 1 at the thumb saddle joint 15 is by a on the lower ring hoop 3 trained support surface 16 supported. The support surface 16 extends as integrally formed broadening of the lower ring hoop 4 on the outside surface 8th of the thumb 2 in the direction of the thumb saddle joint 15 and is with a concave curvature to the ergonomics of the hand 12 customized.

The freedom of movement of the thumb 2 will continue through the joint 14 ensures which an evasion of the thumb base joint 13 when bending allows.

The thumb orthosis 1 in 1 further indicates on both ring straps 3 . 4 each one in the longitudinal direction continuous interruption 18 on which the ring hoops 3 . 4 in each case a left and a right wing 17 Splits. The ring hoop 3 . 4 This is advantageously by plastic deformation of the material of the wings 3 . 4 on the thumb 2 customizable.

With the thumb orthosis according to the invention 1 the effect of a joint surround remains 14 of the metacarpophalangeal joint 13 on the outside surface 8th of the thumb 1 obtained, with the thumb metacarpophalangeal joint 13 through the footbridge 5 which is on the inner surface 10 of the thumb 2 is held in a slightly bent position.

The thumb ground joint 13 will be from the intermittent 18 designed ring straps 3 . 4 that is, with the respective left and right wings cooperating as a ring hoop 17 pressed into the physiologically correct position and the position of the thumb saddle joint 15 corrected only when loaded by grasping so that it in turn is pressed into the physiologically correct position. The thumb saddle joint 15 lies outside the thumb orthosis 1 and is used exclusively according to the force distribution between the thumb orthosis 1 or the thumb base joint supported thereby 13 and the wrist acted upon. This is the base of the thumb 13 with the orthosis 1 held in a slight bend, which prevents it from overstretching, which can be painful.

By at least one ring hoop 3 . 4 a longitudinal interruption 18 has, is achieved in an advantageous manner that the thumb orthoses 1 can be made in mass production. With longitudinal direction is the insertion of the thumb 2 meant. The ring hoops 3 . 4 are divided so that two wings 17 it does not depend on the shape or formation of the interruption 18 arrives, but only insists that both wings 17 can be bent apart or pressed together relative to each other.

According to the invention, different sizes can be produced as a blank with the embodiment. Individual adjustments can be made to the patient directly by changes in the wings 17 be made. The adaptation to the ergonomic requirements are thus easy to implement, with conventional small tools for material processing can be used.

The advantageous subdivision of the ring hoop 3 . 4 in a left and a right wing 17 allows both an adjustment in circumference and diameter by grinding on the mutually associated end faces 29 and then compressing the wings 17 , In addition, an adaptation is possible, with the wings 17 be pressed apart, with the gap of the interruption 18 is enlarged. If the gap for an optimal fit would be too large, can be used on the next basic size of the blank, which would then be narrowed. Thus, with a small number of basic sizes of the blanks, he optimal care of the patient be enough.

According to the invention it is provided that both ring hoops 3 . 4 to the size of the thumb 2 are customizable. Possible embodiments can also be achieved in that only the upper or lower ring hoop 3 . 4 a break 18 having.

The location of the wings 17 to each other according to the invention is achieved in the adaptation by plastic deformation, ie that the material is deformed under application of deformation force, heat or otherwise and then remains unchanged under normal conditions of use in shape, so forms a non-deformable for the thumb joint body or a support.

Thus, the ring hoops 3 . 4 about a simple change of at least one of the two wings 17 on the thumb 2 customizable. It turned out that the break 18 no disturbance of wearing comfort due, but on the contrary the gap in addition to the constructive open design of this thumb orthosis 1 acts as a filigree recess, which prevents moisture from permanently damaging sweat or other liquid substances between the skin and the orthotic material.

The wings 17 have the full effect of a closed ring hoop 3 . 4 ,

In 2 is a thumb orthosis 1 shown in a perspective top view, whereby the arrangement of the web 5 in relation to the ring straps 3 . 4 with the wings 17 is clarified. The upper ring hoop 3 forms with the wings 17 with the jetty 5 an upper opening 6 and with the lower ring hoop 4 with the wings 17 a lower opening 7 , The lower ring hoop 4 is to the support surface 16 widened formed, which by interaction of the left and right wings 17 is formed.

On the thumb orthosis 1 is the jetty 5 between the upper ring hoop 3 and the lower ring hoop 4 as integrated support rail 19 educated. These are the ring hoops 3 . 4 on the body side of the thumb 2 around the thumb base joint 13 widened trained. The thumb ground joint 13 is thus additionally held when gripping the hand in the movement or diffraction plane. The plane of movement or flexion is defined by the axis of articulation of the thumb base joint 13 set and is in the 2 not shown.

When putting on the thumb orthosis 1 becomes the thumb 2 first in the lower opening 7 between jetty 5 and lower ring hoop 4 pushed in and pushed on with a slight bend. The thumb tip happens 20 as well as the thumb end joint 21 the joint mount 14 and will be below from inside through the top opening 6 between jetty 5 and upper ring hoops 3 from the thumb orthosis 1 pushed out. The thumb ground joint 13 is doing in the joint socket 14 introduced, so the bridge 5 on the inner surface 10 of the metacarpophalangeal joint 13 gets into a stable position. This is the upper ring hoop 3 below or on the thumb end joint 21 , Above is in connection with the inventive thumb orthosis 1 always used in the sense of distal (distal) and below in the sense of the body (proximal).

The illustrated thumb orthosis 1 is integrally formed and the above-described components of the ring hoop 3 . 4 with the wings 17 , the support rail 19 and the bridge 5 integrated. So that the wearing comfort is ensured, it is provided that at least two-dimensional areas of individual components of the thumb orthosis 1 filigree recesses 22 exhibit. These can also be designed as ergonomic formations on the surfaces.

The illustrated thumb orthosis 1 has recesses 22 on the integrated support surface 16 , which are distributed to the support rail 19 , Alternatively or additionally, it is possible that the recesses 22 also on the support rail 19 are arranged. The arrangement can be chosen arbitrarily. In particular, can be through the arrangement of the recesses 22 realize in an advantageous manner design effect according to the current aesthetic vocabulary. The recesses 22 have the advantage that the covered areas of the skin 23 when wearing, especially in the areas of Stützflä surface 16 and the support rail 19 stay ventilated, resulting in the interruption 18 the ring hoop 3 . 4 is reinforced. Thus, the thumb orthosis 1 be worn in normal household and professional use, working with dirt and liquids without problems remains possible. The hand 12 can without removing the thumb orthosis 1 be washed, with dirt accumulation between skin 23 and the inner surface 24 the thumb orthosis 1 through the recesses 22 largely omitted. Rather, water flows through the recesses 22 between the thumb orthosis and the skin 23 and, if necessary, removes dirt and impurities.

Furthermore, this area, which can not be adequately accessed by a towel, dries through with the recesses 22 achieved ventilation quickly. Advantageously, the area between skin remains 23 and the inner surface 24 the thumb orthosis 1 thus hygienic.

Even greasing hands 12 stays with the thumb orthosis on 1 according to the invention easily possible because hand cosmetics by the joint socket 14 as well as the recesses 22 to the skin 23 and can spread easily under the thumb orthosis with conventional hand motor skills.

The thumb orthosis 1 is also easy to clean hygienically clean after use due to the open design.

Another advantage is that also thumb 2 with pathological stiffening in the thumb orthosis according to the invention 1 can be included. Thus, it is possible to support the thumb on the one hand and on the other hand to improve the musculoskeletal system. The variety of movements of the thumb 2 in the thumb orthosis it allows the thumb 2 either supported or thumb supported 2 supported in spite of a given limited thumb motor in the usual handles mitzube because, whereby an improvement in mobility and a reduction in stiffening can be achieved.

The invention also includes that the thumb orthosis or at least individual components of the thumb orthosis made of plastic, metal or composite material. It can be used for the thumb orthosis 1 Materials based on functional properties, such as durable optical durability, chemical or physical (light, temperature) resistance, weight and cleanability and handleability are used. But it is also possible to select materials from an aesthetic point of view. Combinations of materials can thereby produce advantageous synergies of the effects, which are also included in the invention. Preferably, noble metal alloys such as gold or silver alloys are used.

With the thumb orthosis according to the invention 1 will reach that thumb 2 can remain in a physiological position during wearing. It is especially avoided that the thumb 2 is kept unnatural and forcibly splayed, which would be associated with significant limitations of the ability to move. Thus, the possibilities of movement of the thumb remain 2 preserved, leaving the muscles of the thumb 2 is further demanded and a counterproductive muscle loss can be avoided.

When wearing the thumb orthosis according to the invention 1 is a permanent stabilization of the thumb 2 and relieves diseased joints. It can be dispensed according to the invention on disturbing tape fasteners.

The inventive thumb orthosis 1 It can also be used as a long-lasting orthosis, as the orthosis ensures that the skin can always dry out and care for the skin remains ensured even when the orthosis is put on. Compatibility on the skin is further enhanced by using water resistant or chemically neutral materials for the orthosis, such as precious metals. By providing with a break 18 and the one as a wing 17 trained ring hoops 3 . 4 can the thumb orthosis 1 with open wings 17 attached to the diseased joint and permanently by plastic deformation of the wings 17 to ring straps 3 . 4 be adjusted.
