Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for a joint and, more particularly, to adapting to correct wrist misalignment while permitting restricted wrist movement. Wrist support that is used.

[0002]

2. Description of the Related Art As is well known, a wrist joint is composed of a plurality of bones disposed between the radius of the arm and the metacarpal bone. One of the most common types of fractures that occurs in humans is the distal radius fracture, the lower radius fracture, commonly known as the Collies fracture. Medical studies have shown that patients with fractures of the distal radius often suffer persistent imperfections, despite healing of the radius. This defect is often due to the inability to restore the correct anatomical positioning between the bony and radial bones of the wrist following fracture. In addition to fractures of the distal radius, misalignment between the caput and radius is also due to destabilization or subluxation of the intervening carpal bone due to wrist ligament damage.

It is known to use casts to immobilize a damaged joint and to use external supports to support the joint and limit its movement. Recent advances in rehabilitation after joint injury have led to the recognition that early and active movement of the injured joint after surgery and other trauma is essential for the fast and complete healing process. .

[0004]

In order to correct misalignment of the hand or forearm due to a fracture of the distal radius, instability of the intervening carpal bone, or injury to the wrist ligament, the hand is generally directed upward or downward. Pressure is required to transrelocate the distal and hand sides of the carpal alignment to the volar or instep sides to align them correctly with the forearm bones. When this is done, the intervening segment (proximal to the carpal alignment) is also aligned correctly. Currently, many types of wrist supports are known in the prior art, but most of such wrist supports have certain inherent drawbacks that reduce their overall usefulness. . The first of these drawbacks is that such a wrist support reduces the headed bone to the volar side or the instep side gradually and actively with respect to the radius about one axis. It is generally impossible to apply the necessary pressure to the hand. As pointed out above, such early and active movement of the wrist joint is essential for promoting an adequate and complete healing process. There is therefore a great need in the art for wrist supports that overcome these and other shortcomings of the prior art. Importantly, a wrist support constructed in accordance with the present invention can correct misalignment of the palm with respect to the forearm and back.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. Referring now to the drawings, there is shown a wrist support 10 constructed in accordance with a first embodiment of the present invention. In the drawing, the wrist support device 10 is shown as an example for a right arm / hand worn on the right hand 12 of the wearer. However, it will be appreciated that the present invention may also be applied to the left-handed embodiment by making the structure of the support 10 the same and inverting its orientation. As best shown in FIGS. 1 to 3, the wrist support device 10 includes a forearm front plate 14 and a forearm rear plate 16. The forearm front plate 14 and the forearm rear plate 16 each have an elongated substantially flat shape, and can be arranged on both sides of the wearer's arm. In this regard, when mounting the support 10, the front plate
14 is located adjacent to the front surface of the wearer's forearm, while rear plate 16 is located adjacent to the back surface of the wearer's forearm. In the preferred embodiment, the front and rear plates 14 and 16 are made of a plastic material that is sufficiently rigid to withstand impact forces and yet is sufficiently lightweight so as not to excessively impair the movement of the wearer's arm. It is a thing. However, in this case, other materials having sufficient strength and rigidity may be considered. On the inner surface of the front plate 14 and the rear plate 16 contacting the forearm, the wrist support 10
Attached is a layer 18 of foam pads used to alleviate the discomfort experienced by the wearer when wearing. The posterior plate 16 further includes a generally arcuate proximal extension 20 formed thereon that is preferably disposed over the distal end of the patient's radius. The attachment of the rear plate 16 to the wearer's arm can be easily performed by the plurality of strap members 22 attached to the rear plate 16. Each strap member includes a velcro tape portion 24 thereon. The method of using the strap member 22 will be described below.

The wrist support 10 of the present invention further includes a post 26 on the side away from the midsagittal plane and a post 28 on the side closer to the midsagittal plane. The spaced side struts 26 and the close side struts 28 each have an elongated shape and can be placed on both sides of the wearer's forearm. When the support device 10 is worn by the wearer, the column 26 on the side of separation is arranged adjacent to the surface of the forearm on the side of separation from the midsagittal plane, and the column 28 on the side closer thereto.
Is located adjacent to the surface of the forearm on the side closer to the midsagittal plane. In the preferred embodiment, the spaced-apart struts 26 and the near-side struts 28 are made of a plastic material that is as strong and rigid as the front and rear plates 14 and 16 and is lightweight. . In addition, other materials with similar characteristics may be considered here. The spaced-apart struts 26 also provide an offset portion 29 for avoiding the great rhombus and scaphoids of the support device 10 when attached to the wearer's hand.
Is advantageously formed to include. As best seen in FIGS. 2 and 3, the spaced-apart struts 26 and the near-side struts 28 are attached to the forearm forearm 14 by a plurality of elongated screw members 30. Each screw member
30 is preferably made of plastic and has four elongated slots laterally provided in the front plate 14.
Threaded through each of the 32. After passing through the slot 32, the first pair of screw members 30 are inserted into and pass through the first pair of holes 34 provided in the support columns 26 on the spaced side. Similarly, the second pair of threaded members 30 are inserted into and pass through a second pair of holes 36 in the strut 28 on the closer side. The screw member 30 includes a spring washer 38 and a nut 40 that are screwed into the screw member 30.
Is fixed so as not to come off from the slot 32.
As will be appreciated, the extent to which the screw member 30 projects from the front plate 14 depends on the positioning of the spring washer 38 and the nut 40 along the length of the screw member 30. In addition, by inserting the screw members 30 into the elongated slots 32, the relative position of each screw member 30 can be adjusted inward or outward relative to the wearer's forearm.

The strut 26 on the side away from the mid-sagittal plane and the strut 28 on the side closer to the mid-sagittal plane are operated by operating the knurled nuts 42 screwed onto the screw member 30. It is placed and fixed on. As will be appreciated, by adjusting the position of the knurled nut 42 along the length of the screw member 30, the spaced side struts 26 and the approaching side struts 28 themselves are selected along the length of the screw member 30. Can be arranged as desired. In this way, the columns on the side to be separated

It can be adjusted by selective placement on top. As will be appreciated, the adjustability of the spaced-apart struts 26 and the near-side struts 28 described above is dependent on the wrist support 10.
Is desired to be specifically tailored to the particular wearer's anatomical requirements. In addition, the adjustability of the spaced post 26 and the approached post 28 with respect to the forearm front plate 14 is utilized to apply downward pressure to the rear surface of the wearer's hand in the manner described below. In particular, as shown in FIG. 1, in order to attach the rear plate 16 to the front plate 14, both ends of each strap member 22 are wound around the column 26 on the side to be separated and the column 28 on the side closer to each other, and The plate 16 and struts 26 and 28 are brought into close contact with the wearer's forearm. The strap member 22 is a strut on the side separated by the magic tape portion 24 included on the strap member 22.
Maintain the position of wrapping around 26 and the struts 28 on the near side.

A hand brace 44 is pivotally connected to the proximal ends of the struts 26 on the side away from the midsagittal plane and the struts 28 on the side closer to the midsagittal plane. When the brace 10 is attached to the wearer's arm, the hand brace 44 is attached to the wearer's hand 12
Is located adjacent to the rear surface of the. In the preferred embodiment, the hand brace 44 has a member 46 on the side away from the midsagittal plane.
And a member 48 on the side closer to the midsagittal plane. The member 46 on the side of separation is an extension 50 on the side of separation from the midsagittal plane.
Is included therein, while the member 48 on the closer side is formed to include an extension 52 on the closer side from the midsagittal plane. The member 48 on the approaching side is
By sliding the T-shaped projection 54 formed on the member 48 on the approaching side into the recess (not shown) of the corresponding shape formed on the member 46 on the separating side, the T-shaped projection 54 is slidable on the member 46 on the separating side. Is preferably connected to. Member on the approaching side
The protrusion 54 of 48 is provided with a pair of female threaded holes 56, while the spaced member 46 is provided with a long narrow hole 58. As can be seen most clearly in FIG. 4, when the spaced apart member 46 is slidably connected to the approaching member 48, the holes 56 are coaxially aligned with the elongated slots 58. In this regard, fasteners such as screws 60 can be threaded through the slot 58, and then through the hole 56, and manipulated to rigidly secure the spaced apart member 46 to the approaching member 48. In addition, by inserting the screw 60 into the narrow hole 58, the distance separating the extension 50 on the side to be separated from the extension 52 on the side to be approached is reduced by the column 26.
And strut 28 can be adjusted to match the adjustments made to the distance separating them.

Referring now to FIGS. 3-5, a hole 62 and a first pair of arcuate slots 64 are provided in the proximal end of the post 28 on the side closer to the midsagittal plane. Although not shown, the proximal end of the post 26 on the side away from the midsagittal plane is provided with a hole and a second pair of arcuate slots. They are arranged in the same shape as shown for the holes 62 and the arcuate slots 64 of the columns 28 on the closer side. The extension 52 on the side closer to the midsagittal plane is provided with a hole 66 and a third pair of arcuate slots 68, while the extension 50 on the side away from the midsagittal plane has a hole ( (Not shown) and a fourth pair of arcuate slots 70 are provided. These are arranged in the same shape as the hole 66 and the arcuate slot 68 of the extension 52 on the approaching side. In the preferred embodiment, the member 48 closer to the midsagittal plane is attached to the closer strut 28 by inserting a first pivot pin 72 into coaxially aligned holes 62 and 66. Similarly, the attachment of the member 46 on the side away from the median sagittal plane to the column 26 on the side of separation is provided with the second pivot pin 74 on the column 26 on the side of separation and the member 46 on the side of separation. It can be easily carried out by inserting it into the coaxially arranged holes. When the spaced-apart strut 26 is connected to the spaced-apart member 46, the arcuate slot 70 is substantially aligned with the arcuate slot provided in the spaced-apart strut 26. In addition, when the approaching post 28 is attached to the approaching member 48, the bow slot 64 is generally aligned with the bow slot 68.

A pivotal connection between the hand brace 44 and the struts 26 and 28 is facilitated by a first pivot pin 72 and a second pivot pin 74. As seen in Figure 8,
Because the wrist skull 75 of the wrist acts as the main pivot point, the pivot pins 72 and 74 must function properly for the wrist support 10 to function properly.
Must be placed on the axis A that extends laterally through the headed bone 75 and be placed on both sides of the headed bone 75. To prove that such an arrangement was obtained, the pivot pin 72
And 74 are made of a radiopaque material so that they can be confirmed by X-ray imaging. As pointed out above, the distance separating the strut 26 on the side away from the midsagittal plane and the strut 28 on the side closer to the midsagittal plane is the screw member 30 in the elongated slot 32 of the front plate 14. It can be adjusted by adjusting the position of. Hand brace 44 is a prop
Since they are pivotally connected to 26 and 28, the distance separating the member 46 on the side away from the midsagittal plane of the hand brace 44 and the member 48 on the side closer to the midsagittal plane is the strut 26 and the strut.
28 must be adjusted by a distance corresponding to the desired increase or decrease in separation. As also pointed out above, such adjustment may be effected by the member on the side separating the T-shaped projection 54.
This is facilitated by a sliding fit in the corresponding recesses provided in 46. Therefore, by loosening the screw 60, the support member on the side separating the member 46 on the separating side is separated.
26 can be moved simultaneously and the approaching member 48 can be moved simultaneously with the approaching column 28. In the preferred embodiment, the spaced apart member 46 and the approached member 48 are both made of plastic. However, it will be appreciated that other materials may alternatively be utilized. 4 and 5, the degree of pivoting motion between the hand brace 44 and the struts 26 and 28 is
It is controlled by a plurality of stopper members 76. In the preferred embodiment, each stopper member 76 includes fasteners such as screws 78. The fastener is first inserted into the cylindrical bush 80 and then into the female threaded locking member 82. The first pair of stopper members 76 is a pair of arcuate small holes arranged side by side.
64 and 68, a second pair of stopper members 76 are inserted into arcuate slots 70 aligned with the arcuate slots provided at the proximal end of the post 26 on the side away from the midsagittal plane. . When the stopper members 76 are placed in each pair of aligned slots, the hand brace 44 can move as shown in FIG. As will be appreciated, by adjusting the relative position of the stopper members 76 in the side-by-side pairs of fine holes, the hand bracing
44 movements can be controlled, ie limited. In this regard, one pair of stopper members may be placed to limit wrist extension and the other pair of stopper members may be placed to limit wrist bending.

As can be seen most clearly in FIGS. 3 and 4, the hand-contacting inner surface of the hand brace 44 provides a firm and soft contact between the hand brace 44 and the rear surface of the wearer's hand. Adapter pad used for
84 is installed. The adapter pad 84 also includes a velcro strip 86 that is releasably attached to a velcro strip 88 on the inner surface of the hand brace 44 on the outer surface thereof. The adapter pad 84 further reduces the discomfort or irritation of the wearer's hand 12,
It includes a layer 90 of cushioning material attached to its bottom surface.

Referring now to FIG. 6, the wrist support 10 of the present invention further includes a palm plate 92 positioned adjacent the palm surface of the wearer's hand. In the preferred embodiment, the palm plate 92 is a palm plate as shown in FIG.
Includes a bracket 94 attached to it that is used to facilitate attaching 92 to hand brace 44. In this regard, the bracket 94 has a hand brace 4
4, more specifically the member 46 on the side away from the midsagittal plane
A Velcro tape portion 96 is detachably attached to a Velcro pad cloth 98 provided on the upper surface of the. Palm plate 92 further includes a layer 100 of cushioning material attached thereto to provide soft contact between palm plate 92 and the palm surface of the wearer's hand. As shown in FIG. 7, a belt member 102 made of a flexible material is provided to attach the palm plate 92 to the hand brace 44,
Maintaining the hand brace 44 in firm contact with the rear surface of the wearer's hand 12. The belt member 102, which includes the velcro cloth 104, is fitted to the palm plate 92 and the hand brace 44 as shown in FIG. In particular, the belt member 102 is wrapped around the wearer's hand with the extension 106 formed therein hanging between the wearer's thumb and index finger.

With the above structure, the operation of the wrist splint 10 of the present invention can be described. First, forearm front plate 14
Is positioned adjacent to the front surface of the wearer's forearm and the wearer's hand 12 is positioned such that the hand brace 44 is positioned adjacent to the back surface of the hand 12. Importantly, once such positioning of the forearm front plate 14 and hand brace 44 is obtained, the stopper member 76 is tightened to secure the hand brace 44 in a fixed position substantially parallel to the front surface of the wearer's hand, i.e. Maintain a neutral position. Next, the post on the side away from the midsagittal plane
26 and the struts 28 on the side closer to the midsagittal plane so that they are arranged with respect to the side of the wearer's forearm away from the midsagittal plane and the side closer to the midsagittal plane. Adjust to. More specifically, the nut 40 is loosened and the screw member 30 is slid in the slot 32 formed in the front plate 14 to adjust the distance separating the support column 26 and the support column 28. When adjusting the distance separating the column 26 on the separated side and the column 28 on the closer side, the member 46 on the side separated from the midsagittal plane is the member on the side closer to the midsagittal plane of the hand brace 44. Loosen the screws 60 that are firmly attached to the 48 so that the spaced member 46 and the closer member 48 slide relative to each other by a distance consistent with the distance adjustment made between the struts 26 and 28. To With the columns 26 and 28 in place, tighten the nuts 40 to keep the screw members 30 in the correct position and tighten the screws 60.
To maintain proper positioning of the spaced member 46 and the approaching member 48. In addition, by loosening the knurled nut 42, placing the struts 26 and 28 in the desired position along the length of the screw member 30, and positioning them approximately midway between the front and back of the wearer's arm, Pillar 26 and
Adjust the distance separating 28 and front plate 14. After placing the front plate 14 and the columns 26 and 28 on the wearer's forearm, the forearm rear plate 16

Is positioned such that the arcuate extension 20 formed therein is located on the distal end of the wearer's radius. Once the wrist support 10 has been secured to the wearer's forearm, the hand brace 44 may be positioned downwards relative to the second metacarpal bone 21 and the third metacarpal bone 23 (shown in FIG. 8) of the wearer's hand 12. Apply pressure. In the preferred embodiment, such pressure causes the strut 26 on the side away from the midsagittal plane and the strut 28 on the side closer to the midsagittal plane to be threaded 30.
It can be easily added by moving it down the lengthwise direction towards the front plate 14. As previously stated, the hand brace 44 is first secured in the neutral position. Therefore, the pillars 26 on the separated side and the pillars 28 on the close side are
The hand brace 44 by moving the
When contacted with the above-described downward pressure, the abuts against the rear surface of the wearer's hand. Such downward pressure is necessary to produce a volar reduction that corrects the misalignment of the wearer's hand, wrist and forearm bones as seen in FIG.

When the front plate 14 and struts 26 and 28 are properly positioned about the wearer's forearm, the first pivot pin 72
And second pivot pins 74 are preferably located on opposite sides of the capped bone 75 of the wearer's wrist. As I pointed out earlier,
The first pivot pin 72 and the second pivot pin 74 are X
It is composed of a radiopaque material, as can be seen by the lines. Therefore, in order to confirm that the pivot pins 72 and 74 are properly positioned adjacent to the caput bone 75, an X-ray of the wearer's hand is taken and the pivot pins 72 and 74 are taken.
Guarantee that the correct placement of is obtained. If the pins 72 and 74 are not properly placed, the front plate 14 and the post 26
And 28 are repositioned on the wearer's forearm and another X-ray is taken to confirm the placement of the pivot pins 72 and 74. This particular method is repeated until the correct positioning of the pivot pins 72 and 74 is obtained. The x-rays also show the downward pressure exerted by the hand braces 44 on the wearer's hand,
It is also used to determine if the wrists and forearms are properly aligned as shown in FIG. Therefore, if it is determined that the correct arrangement is not obtained, the column 26 on the side away from the midsagittal plane and the column 28 on the side close to the midsagittal plane.
The pressure exerted by the hand brace 44 is adjusted by repositioning the screw with respect to the screw member 30. In addition, if the brace 44 is moved to its lowest position, but the wearer's hand is too small to apply sufficient pressure by the hand brace 44, additional padding may be added to the inner surface of the adapter pad. May be stacked and the required pressure may be applied.

After the forearm forearm plate 14 and the struts 26 and 28 are correctly arranged and the correct bone arrangement is obtained, the Velcro pad cloth 96 of the bracket 94 is attached to the outer surface of the member 46 on the side away from the midsagittal plane. Hand-braces the palm plate 92 by fixing it to the provided Velcro pad cloth 98.
Attach to 44. The palm plate 92 is attached to the hand brace 44 in such a way that the cushioning material 100 contained therein is in firm contact with the palm surface of the wearer's hand. After proper placement of the palm plate 92, the belt member 102 is wrapped around the wearer's hand 12 with the extension 106 of the belt member 102 hanging between the thumb and index finger of the wearer's hand 12. The belt member 102 is maintained in the correct position by the use of Velcro patch cloth 104 contained therein.

The downward pressure exerted by the hand braces 44 on the second and third metacarpal bones is due to a distal radius fracture (ie, Collies fracture), intervening carpal instability or wrist ligament damage. Produces volar reduction as needed to correct hand or forearm misalignment due to subluxation. Since the pressure on the metacarpal bone is kept constant,
The wrist can be swung or rotated slightly without causing further damage or impeding the healing of any of the above-mentioned damage. Exactly
As mentioned earlier, slight movement of the wrist during the healing process accelerates the healing process. In the early stages of the healing process, the stopper member 76 is positioned in such a way that it does not allow the wrist of the wearer to pivot. As the healing process progresses, the position of the stopper member 76 may be adjusted to increase the degree of bending and / or stretching of the wearer's wrist.
The use of the belt member 102 keeps the adapter pad 84 of the hand brace 44 and the cushioning material 100 of the palm plate 92 in firm contact with the wearer's hand 12. Next in FIG.
