RELATED APPLICATION DATAThis application is a continuation of U.S. patent application Ser. No. 13/492,363, filed Jun. 8, 2012, now U.S. Pat. No. 8,758,284, which claims the benefit of U.S. Patent Application Ser. No. 61/494,550, filed Jun. 8, 2011, which are hereby incorporated herein in their entirety by reference.
TECHNICAL FIELD FOR THE INVENTIONThe present invention relates to a convertible orthotic brace and especially to a flexible orthopedic brace providing for convenient adjustment to fit a wearer by adjustment to multiple configurations.
BACKGROUND OF THE INVENTIONSeveral prior art orthotic braces feature front and rear panels to provide lumbar support to the patient.
For instance, in U.S. Pat. Nos. 6,478,759 and 5,967,998, hereby incorporated herein by reference, a single front support panel is attached to one or more rear panels to provide lumbar support to the patient upon closure. Devices of this type provide better support in comparison to belt-type devices. These devices may feature a reinforcement insert, typically of relatively rigid plastic, inserted into a soft material rear portion which in turn is connected to a front portion by straps.
Other braces of the prior art include those described in U.S. Pat. No. 4,202,327 having a number of straps for connecting right and left sections with the straps secured to the jacket with hook-and-loop strips. U.S. Pat. No. 4,508,110 describes a jacket-type orthoses that limits motion in the thoracic or lumbo-sacral areas and uses a rigid orthoses design that may be adjusted by a patient pulling on a plurality of laces, each attached to a short strap having hook-and-loop material thereon which is used to attach the straps to predetermined positions on the rigid brace members. Other prior art U.S. patents for orthoses include U.S. Pat. No. 4,475,543, for a lumbo-sacral brace using an elastic belt fastened with a pouch in combination with a semi-wrap-around polyurethane foam splint cured in place in the pouch; U.S. Pat. No. 2,100,964, describing a surgical belt is illustrated in which a plurality of laces are interconnected to a single strap on either side thereof; and U.S. Pat. No. 3,926,183, disclosing a dorsal lumbo sacral support combines elastic and non-elastic straps in a support device for a person's back, thoracic or pelvic areas.
U.S. Pat. No. 3,927,665 relates to a lumbo-sacral support having an elastic body encircling band and inelastic tensioning system, while U.S. Pat. No. 5,074,288 illustrates a soft body brace attached to a patient with a plurality of straps to provide a back support system with interchangeable and positionally adjustable orthotic support.
U.S. Pat. No. 4,175,553 is also a lumbo-sacral orthosis orthopedic support for encircling the torso and has a plurality of straps, and U.S. Pat. No. 4,459,979 is an orthopedic appliance made of resilient material conforming to the lower back of a person and uses a plurality of adjustable straps.
U.S. Pat. No. 5,362,304 discloses a thoracic lumbar sacral orthosis device formed as a jacket and has support plates which can attach thereto, and U.S. Pat. No. 5,188,585 concerns a lumbo-sacral orthopedic support which encircles the torso of a patient and has adjustable strap portions. U.S. Pat. No. 4,559,933 describes an orthopedic lumbo-sacral corset using semi-rigid elements and inflatable pads.
The aforementioned patents are hereby incorporated herein by reference.
One of the problems with orthotic braces of the prior art is that they cannot be used as both a smaller lumbosacral belt (“LSB”) type orthotic brace and as a relatively larger lumbosacral orthotic (“LSO”) type brace.
Accordingly, it is desirable to provide an orthotic device that allows for the relatively convenient conversion between a smaller LSB type orthotic brace and as a relatively larger LSO type brace.
In addition, it is also desirable to provide an LSB-LSO convertible type orthotic brace with an improved supplementary sternal support for the upper thoracic area. Such supports of the prior art are designed with a ventral support rod extending from the frontal portion of the belt. This is relatively stiff and unyielding, and can feel confining for the wearer.
Accordingly, it is desirable to provide effective supplementary sternal support without relying upon a support that extends from the wearers front while providing equivalent supplementary sternal support.
In addition, it is normally inconvenient for wearers to be able to don and remove such a supplementary sternal support without disrupting the custom fitting of its attachment to the wearer. Thus, in this regard, it is also beneficial to provide such a supplementary sternal support that may be readily donned and removed by the wearer without the need to reposition the fitments that position the supplementary sternal support.
Accordingly, in light of the aforementioned shortcomings of currently available orthotic braces, there is a need for a convertible lumbar orthosis which can be adjusted on the patient so as to provide optional LSB- or LSO-type support while conforming to the back of a patient to provide a more customized fit.
In addition, there remains a need for LSO-type devices that permit the optional use of a supplementary sternal support without sacrificing comfort and ease of donning and removal while maintaining its customized fitting and support settings, such as by having to rearrange the straps of the brace.
SUMMARY OF THE INVENTIONThe present invention includes an orthotic brace which offers advantages in being able to be adjusted to fit the small of the back of a specific wearer, and may be altered to be converted from a smaller LSB-type brace or a larger LSO-type brace, while providing effective reinforced lumbar support and comfort to the wearer.
The present invention includes a flexible lumbo-sacral orthopedic (LSO) brace which fits closely to the patient's torso while being easily attached and tightened in a wide variety of positions for a wide variety of body shapes and provides for optional ventral supports removably attachable thereto.
The present invention may also be embodied as a thoraco-lumbo-sacral orthopedic (TSLO) brace which typically has a longer rear portion and includes shoulder straps (not shown) which variation is known in the art. However, this embodiment of the present invention may optionally feature a supplementary sternal support.
Accordingly, as used herein, the term “lumbo-sacral orthopedic brace” shall be understood as including both LSO and TSLO variations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSIn accordance with the foregoing summary of the invention, the following presents the preferred embodiments of the present invention, which are considered to be the best mode thereof.
FIG. 1 is a plan view of an orthotic brace in accordance with one embodiment of the present invention, showing the orthotic brace in an open, extended configuration, as seen from the inner side of the brace.
FIG. 1 showsorthotic brace1 which comprises a firstlateral belt portion2 and a secondlateral belt portion3. The first and second lateral belt portions are sized and adapted to overlap across the wearer's ventral area when the orthotic brace is donned, and to be releasably attached to one another in this region such as by virtue of opposing hook-and-loop closure portions4 and5 (the latter not shown in this view).
Theorthotic brace1 also comprises a central dorsal portion6 (not shown in this view). Also shown inFIG. 1 are the optionalpreferred laterals pads7 and8.
The first and second lateral belt portions preferably are made of a flexible polymeric material such as those known and used in the art.
The support panels and portions may be made of any dimensionally stable material, typically rigid enough to provide reinforcement to the lumbar portion of the brace, such as in reinforcement inserts known and used in the art, such as through use of a polymeric material. In a preferred embodiment, and as a non-limiting example, the support panels and portions may be made of any dimensionally stable material such as ABS plastic of at least one-eighth inch in thickness.
The optionalinner pad portions7 and8 may be constructed of any appropriate cloth or foam material (or combination thereof). This is known and used in the orthotic brace field.
In order to provide a supplementary closure, theorthotic brace1 may also include asupplementary strap9 which may extend from the rear portion of the brace across one of the lateral belt portions (such aslateral belt portion2 in this embodiment), to close the front of the brace by being provided with a corresponding hook-and-loop material that is adapted to engage a hook-and-loop portion4 in the same manner as hook-and-loop portion5. In addition, the preferred embodiment of theorthotic brace1 may also include tighteningstraps10 and11, which are, respectively, attached to the rear (dorsal) portions of the secondlateral belt portion3 and firstlateral belt portion2, such that when straps10 and11 are pulled in the forward direction by the wearer, the first and secondlateral belt portions2 and3 are cinched tighter with respect to one another, as may be appreciated from the other Figures herein.
FIG. 1 also shows removable secondary dorsal rigidangled support panel12 which is larger than the first rigid angled dorsal support panel incorporated into centraldorsal portion6, and is adapted to be nested against the first rigid angled dorsal support panel and along its inner-facing surface.
The first rigid angleddorsal support panel13 may be seen in other Figures.
FIG. 2 is a rear perspective view of anorthotic brace1 shown as it would appear when donned by a wearer, and wherein like numerals designate portions of the orthotic brace as described herein. This view shows first and secondlateral belt portions2 and3 as well as showing the centraldorsal portion6 of theorthotic brace1. From this Figure, one can appreciate the preferred flexible attachment arrangement in which case the firstlateral belt portion2 have two substantially parallel and horizontally extending upper andlower slots2aand2blocated at the dorsal end thereof; and wherein the secondlateral belt portion3 is provided with two substantially parallel and horizontally extending upper and lower slots (not visible in this view), and in substantial alignment withslots2aand2b, in its dorsal. The arrangement and orientation of these slots allows for the placement ofpins14 and15 throughrespective discs16 and17 (and wherein thepins14 and15 are also attached to similar interferent portions such as discs similar todiscs16 and17 attached, respectively, topins14 and15 and located in board of second lateral belt portion3).
Theslots2aand2b(as well as corresponding openings in second lateral belt portion3), are of sufficient length and width to allow first and second lateral belt portions to be moved with respect to one another generally along the direction arrow A, as well as to allow the first and secondlateral belt portions2 and3 to be slightly angled with respect to one another to allow the respective longitudinal axes to be angled with respect to one another. In addition, the slots preferably are sized to allow the wearer to snug the brace by pulling uponstraps10 and11 in order to cinch the orthotic belt around the wearer's waist.
FIG. 2 also shows hook-and-loop closure panels12aand12bthat engage corresponding hook-and-loop material on the inner surface of first rigid angled dorsal support panel13 (designated13aand13b). This allows thesupport panels12 and13 to remain nested against one another.
Also shown inFIG. 2 isoptional fabric envelope18 that may be used to surround movable secondary dorsal rigidangled support panel12.
FIG. 3 is a plan view of anorthotic brace1 in accordance with the preferred embodiment of the invention, and wherein like referenced numerals refer to portions of the brace as already described herein. This view showsinner padding portions7 and8 as well as first and secondlateral belt portions2 and3. Also visible in this view is the hook-and-loop closure portion5 that attaches to hook-and-loop closure portion4 as shown inFIG. 1. This view also shows the position and attachment of the first rigid angleddorsal support panel13 as a part of the centraldorsal portion6 of theorthotic brace1. Also seen in this view are the hook-and-loop closure panels13aand13bthat attach, respectively, to hook-and-loop panels12aand12b.

FIG. 4 is a front perspective view of anorthotic brace1 in accordance with the preferred embodiment of the invention, as would appear once donned and closed by the wearer, and wherein like numerals refer to like portions of the brace as described herein. From this Figure, one can appreciate how the brace is closed by the overlapping of the first and secondlateral belt portions2 and3, followed by the overlapping ofsupplementary belt9 by the cinching of the first and secondlateral belt portions2 and3 by action ofstraps10 and11 which are pulled toward the front of the belt using D-rings10aand11a. The inner surfaces ofstraps10 and11 are likewise provided hook-and-loop closure materials which, in the case ofstrap10, attach to the outside ofsupplementary strap9 and, in the case ofstrap11, attach to a hook-and-loop panel such as that provided by hook-and-loop panel4.
Also visible inFIG. 4 is a removable ventralrigid support panel20 that is tucked inside theorthotic brace1 prior to its closure. The removable ventralrigid support panel20 may also preferably be enclosed in a fabric envelope similar tofabric envelope18 for added comfort to the wearer. Removable ventralrigid support panel20 is shown in greater detail inFIG. 5 which shows removable ventralrigid support panel20 encased infabric envelope21 which, for instance, may have a slit opening along its top which may be closed by hook-and-loop flaps21aand21bthat engage the front surface offabric envelope21. In addition, the front surface offabric envelope21 may also be provided with a hook-and-loop closure panel21cwhich may attach to the inner surface of the orthotic brace, such as by being adapted to engage the inner surface(s) offabric portions7 and8 of the front of the brace once closed.
Fabric envelope18 is shown in an open condition inFIG. 6 which is a plan view thereof. From this view, one can appreciate thatfabric envelope18 may be closed over removable secondary dorsal rigidangled support panel12 once it is placed in the nested position against first rigid angleddorsal support panel13, such as engagement of hook-and-loop closures18awith18band hook-and-loop closure18cwith18d.
Removable secondary dorsal rigidangled support panel12 is shown in more detail inFIG. 7. This Figure shows how thesupport panel12 is bent at an angle theta (θ), and it is preferred that this angle be in the range of 10-30 degrees preferably 15-25 degrees and most preferably 18 to 23 degrees. This angle will preferably be mirrored in the angling of the first rigid angleddorsal support panel13 such that the two pieces may be nested most firmly.
The donning of theorthotic brace1 in accordance with the present invention is shown in stepwise fashion inFIG. 8. To don the device, the wearer will hold the device as shown instep1 and support it as removable ventralrigid support panel20 is positioned approximately in front of the wearer's stomach area, as shown instep2. Withpanel20 in position, first and second lateral belt portions are arranged in overlapping relationship such that the hook-and-loop panels4 and5 engage one another, as shown instep3. Instep4, the wearer grasps the D rings ofstraps10 and11 and pulls the straps outwardly and forward such that the first and secondlateral belt portions2 and3 cinch with respect to one another across the wearer's back. This may also be appreciated from the view instep5. Once the brace is cinched into a comfortable position, the wearer can close theorthotic brace1 by closingsupplementary strap9 across the front of the brace as shown instep6.
