The present invention relates to shoulder braces.
Each year approximately 71,000 primary anterior shoulder dislocations occur in athletes playing high impact sports and can occur with other at-risk populations as well. See, Lauren Pearson, Young Men and Elderly Women at Biggest Risk for Shoulder Dislocations, Amer. Aca. of Orthopaedic Surgeons, Mar. 1, 2010. These individuals can be at increased risk for recurring dislocations. To lower this risk, patients are often prescribed one of two conventional shoulder orthotics, the SULLY brace or the SAWA brace, both manufactured by DonJoy Orthotics. However, the SULLY device is often thought to be too restrictive and uncomfortable and can impair athletic performance while the SAWA device, while more comfortable, may not provide enough stability to prevent recurrence of a dislocation.
Embodiments of the present invention provide semi-rigid shoulder braces that provide stabilization of anterior glenohumeral ligaments without immobilizing the shoulder joint.
Shoulder braces for inhibiting secondary anterior shoulder dislocations are configured to allow for a wide range of motion while also providing shoulder joint stabilization.
Some embodiments are directed to shoulder braces that include a brace body with an arm portion configured to reside about a shoulder of a user and a torso portion. The braces include a plurality of shoulder straps extending over the single arm portion shoulder and a substantially rigid thermoplastic insert releasably held by the arm portion of the brace body. The insert has a user-specific custom shape that substantially conforms to a shoulder of the user. The brace also includes at least one adjustable length laterally extending torso strap attached to the torso portion.
The brace body can include an expandable, breathable compressive fabric.
The at least one torso strap can be a single strap that has an adjustable length and resides on only one side portion of the brace body. An opposing side portion can include two long edge portions that are releasably attachable.
The plurality of straps can include closely spaced straps that extend from a front upper portion of the brace body to a rear upper portion of the brace body and that are sized and configured to provide stabilization of ligaments. The straps have adjustable lengths.
The insert can substantially conform to an underlying gleno-humeral joint of the user/patient.
The brace can include an inner pocket that releasably holds the insert therein.
The insert can be held by a pocket attached to an internal surface of the brace body.
The insert can have a thickness between about 0.125 inches to about 0.25 inches.
The brace body can be formed from a stretchable compressive material that is configured to substantially conformably attach to the user and allow for resilient expansion to accommodate breathing.
Other embodiments are directed to methods of providing support to a user such as an athlete to inhibit secondary anterior shoulder dislocations. The methods include: (a) providing a shoulder brace with a plurality of shoulder straps residing over a single sleeve and a torso portion that has a substantially rigid insert that resides in a sleeve, the sleeve encasing an upper portion of a user's arm and compromised shoulder; (b) allowing a functional substantially full range of motion when the user wears the shoulder brace; and (c) providing compressive support to a glenohumeral joint of the compromised shoulder while also providing natural supportive function of shoulder ligaments when the user wears the shoulder brace.
Still other methods are directed to methods of treating a subject at risk for shoulder dislocation or needing support of a shoulder. The methods include: (a) providing a shoulder brace with a single arm portion and a torso portion; (b) molding a thermoplastic insert to conform to a shape of a humeral head of a shoulder of a patient; and (c) inserting the molded thermoplastic insert into the arm portion of the shoulder brace.
The providing step may optionally be carried out by providing at least one moldable insert in a kit with a compressible breathable fabric shoulder brace body. The shoulder brace can include a plurality of adjustable length shoulder straps that reside over the insert in the arm portion of the shoulder brace.
It is noted that aspects of the invention described with respect to one embodiment, may be incorporated in a different embodiment although not specifically described relative thereto. That is, all embodiments and/or features of any embodiment can be combined in any way and/or combination. Applicant reserves the right to change any originally filed claim or file any new claim accordingly, including the right to be able to amend any originally filed claim to depend from and/or incorporate any feature of any other claim although not originally claimed in that manner. These and other objects and/or aspects of the present invention are explained in detail in the specification set forth below.
Other systems and/or methods according to embodiments of the invention will be or become apparent to one with skill in the art upon review of the following drawings and detailed description. It is intended that all such additional systems, methods, and/or devices be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.
Other features of the present invention will be more readily understood from the following detailed description of exemplary embodiments thereof when read in conjunction with the accompanying drawings.
The present invention now is described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Like numbers refer to like elements throughout. In the figures, the thickness of certain lines, layers, components, elements or features may be exaggerated for clarity. Broken lines illustrate optional features or operations unless specified otherwise. One or more features shown and discussed with respect to one embodiment may be included in another embodiment even if not explicitly described or shown with another embodiment.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. As used herein, phrases such as “between X and Y” and “between about X and Y” should be interpreted to include X and Y. As used herein, phrases such as “between about X and Y” mean “between about X and about Y.” As used herein, phrases such as “from about X to Y” mean “from about X to about Y.”
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
It will be understood that when an element is referred to as being “on”, “attached” to, “connected” to, “coupled” with, “contacting”, etc., another element, it can be directly on, attached to, connected to, coupled with or contacting the other element or intervening elements may also be present. In contrast, when an element is referred to as being, for example, “directly on”, “directly attached” to, “directly connected” to, “directly coupled” with or “directly contacting” another element, there are no intervening elements present. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.
Spatially relative terms, such as “under”, “below”, “lower”, “over”, “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of over and under. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly”, “downwardly”, “vertical”, “horizontal” and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention. The sequence of operations (or steps) is not limited to the order presented in the claims or figures unless specifically indicated otherwise.
The term “about” means that the recited number or value can vary by +/−20%.
Embodiments of the invention are particularly suitable for human uses and/or some veterinary uses.
Turning now to the figures,
Suitable breathable fabrics include neoprene or other materials that have “stretch” or elastomeric fibers such as spandex. LYCRA® is an example of a spandex stretch fiber. Other stretch fibers may also be suitable. Such stretch fibers may include, but are not limited to, fibers presently classified in the polyester textile label classification of the U.S. Federal Trade Commission, but under which a new subclass of “elasterell-p” has been proposed; these, may also be suitable as stretch fibers as the are described as inherently elastic, bicomponent textile fibers consisting of two substantially different forms of polyester fibers (DuPont's version of this fiber is referred to as “T400”).
In other embodiments, the brace body 10b can include a zipper that attaches the two edge portions 12. The two edge portions 12 may be on the side or may reside in a center or other user accessible portion of the torso portion 10p brace body to allow for easy donning and removal.
The brace body 10b can include portions that are compressive and portions that are not. The brace body 10b can be a monolithic single layer or multi-layer configuration. The brace body 10b can include a plurality of different materials, defining different portions of the brace body. In some embodiments, the brace body 10b includes a pocket 15 for an insert 40 (
As shown in
The brace 10 can also include at least one laterally extending adjustable torso strap 30 that resides proximate to but under the arm at an upper to medial portion of the torso. The at least one torso strap 30 can be a single strap or more than one strap. Where multiple torso straps 30 are used, they can reside on a single side of the brace, typically on the same side as the shoulder straps 20 or on different sides (or even front or back). The torso strap 30 can be used to tighten the brace to conform to the user while allowing for resilient chest expansion during breathing. The torso portion 10p of the brace 10 with the torso strap 30 can allow for outward expansion of up to about three inches.
The pocket 15 can be an externally accessible pocket formed in the compressible material of the brace body 10b. However, as shown in
As shown in
Although not required, the insert 40 may optionally include a gel or neoprene material that provides padding for additional comfort.
The insert 40 can be heated to between about 65° C.-70° C. (150° F.-160° F.) for a about 1 minute and allows for a work time of between about 3-5 min to form the desired shape. The area of the insert 40 may vary depending on size of the brace (e.g., XS, S, M, L, XL and the like) but typically has an area that is between about 10 in2 to about 20 in2. In particular embodiments, the insert 40 can be about 0.125 inch thick with a 3×5 inch substantially oval shape. In other embodiments, other geometric shapes such as polygons can be used. In some embodiments, the insert 40 can be a custom-fitted (low temperature) thermoplastic insert that substantially conforms to a user's shoulder (external anatomy over a humeral head) to increase support and proprioception and can be easily inserted and removed from its designated pocket on an interior facing side the brace 10.
The insert 40 cooperates with the brace body 10b providing a semi-rigid device that provides support for weakened anterior shoulder ligaments as a result of dislocations.
While particularly suitable for athletes experiencing or at-risk for recurring anterior shoulder dislocations, the braces 10 are also suitable for anyone desiring additional shoulder support.
As shown in
The brace 10 can restrict abduction and external rotation of the shoulder joint to about 90 degrees combined abduction and external rotation, which can provide stabilization in the area of the anterior glenohumeral ligaments and provide sufficient force to keep the shoulder in place without immobilizing the joint.
The brace body 10b can comprise a breathable neoprene fabric which is lightweight and has a low profile fit allowing it to fit under athletic clothing and/or padding such as those often worn by athletes.
The brace 10 can be provided in a range of sizes to accommodate different size users, e.g., extra small (XS), small, medium, large, extra large and even larger (typically 2XL and 3XL). The brace 10 can be provided in pediatric and adult size ranges and/or female to male configurations. Female configurations may have a different torso shape or size. Female adult sizes may be provided in a range of cup and chest sizes for better form fit.
In some embodiments, the brace 10 is configured to allow for relatively quick donning and removal (e.g., on and off) times by a person without requiring any assistance for most users. This convenient self-assembly and removal can promote compliance and potentially avoid recurrence of shoulder dislocations.
The providing step can be carried out by providing at least one moldable insert in a kit with a compressible breathable fabric shoulder brace body. The shoulder brace can include a plurality of adjustable length shoulder straps that reside over the insert in the arm portion of the shoulder brace and the method can include adjusting the straps to provide desired support and compressive strength of the insert against the shoulder (block 105).
The insert can be heated at a clinic or doctor's office to make it malleable, then the insert can be shaped for the molding step (block 115). The brace can be provided in a package with a training manual, template or instruction sheet and/or a web link to a video that shows how to mold the insert. The insert may also come with indicia of orientation for placement into the brace (e.g., pocket) such as “up” or “down” or “faces in” or “faces out” surface markings (arrows, icons or images may also be used).
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
