BUNION SPLINT ASSEMBLY WITH ADJUSTABLE SUPPORT CUSHION

CROSS-REFERENCE TO RELATED APPLICATION(S)

[0001] This application claims the benefit of priority of U.S. Non-Provisional Patent Application No. 18/220,545, filed on July 11, 2023, and U.S. Provisional Patent Application No. 63/388,596, filed on July 12, 2022, the disclosures of which are hereby incorporated by reference herein in their entireties.

BACKGROUND

[0002] A bunion is an inflammation of the bursa that normally cushions the metatarsophalangeal (MTP) joint. When the big toe moves toward the second toe, the inner half of the bursa can become pinched causing the outer half to bulge with the appearance of a bonelike projection. This inflammation can be sensitive to the touch, especially in the center of the bulge. Treatments for bunions often include pharmaceutical approaches such as the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and other anti-inflammatory drugs. Other approaches utilize mechanical structures that apply pressure to realign the toe while providing a cushion to surround the bunion. However, these approaches fail to facilitate optimal placement of the cushion, which can exacerbate the inflammation.

DETAILED DESCRIPTION

[0035] A bunion splint assembly with an adjustable support cushion is described herein. A cushioning ring can be used as a support cushion to surround the bunion without contacting the sensitive projected area. This allows for the avoidance of pressure on the bunion that would occur if a bandage was used, and protects the bunion from be subjected to added pressure that can exacerbate the inflammation. Proper placement of the ring-shaped cushion around the bunion is important for ensuring that no pressure is exerted on a central portion of the bunion by the protective ring or by other components of the bunion splint assembly. As each individual has a different distance of the MTP joint to the end of the big toe, the position of the protective cushion or ring should be adjusted to improve the effectiveness in alleviating bunion pain.

[0036] Certain embodiments of the present disclosure address these problems and others by utilizing a moveable and repositionable support cushion (e.g., a ring-shaped cushion). The embodiments advantageously reduce bunion inflammation and pain by aligning the big toe for increased comfort and correction without applying pressure to sensitive portions of the bunion. The bunion splint assembly can be a universal size that fits and adjusts to all foot shapes.

[0037] FIGS. 1A and IB show an outer surface 102 A and an inner surface 103 A, respectively, of an illustrative bunion splint assembly 100 A designed for the left foot in accordance with at least one embodiment. The bunion splint includes a flexible body 101 A shaped to conform to the foot and a plurality of straps 104A, 108A, 110A, and 112A disposed along an outer seam 106A of the flexible body 101 A that secure the flexible body 101 A in place when worn. In at least one embodiment, an elongated rigid member 114 A, such as a substantially flat metal bar, is disposed within fabric layers (e.g., foam layers) between the outer surface 102A and the inner surface 103A of the flexible body 101A so as to not contact the skin of the wearer. When the flexible body 101 A is secured to the foot, the elongated rigid member 114A (with its the shape being illustrated despite being obscured by the fabric of the outer surface 102A and the inner surface 103 A) is aligned along the side of the foot corresponding to the location of the big toe. In at least one embodiment, the elongated rigid member 114A is permanently disposed between the treatment site-engaging surface 105 A and the opposing outer surface 102A (e.g., the two surfaces are sewn together). In at least one embodiment, the elongated rigid member 114A is removable from between the treatment site-engaging surface 105 A and the opposing outer surface 102 A, for example, via a slot or pocket. For example, in at least one embodiment, metal bar can be removed and replaced with a material of different stiffness/thickness as desired.

[0038] In FIG. IB, a ring-shaped cushion 120A is shown affixed to the inner surface 103A of the flexible body 101 A at a treatment site-engaging surface 105A, which is above the elongated rigid member 114A. In at least one embodiment, the ring-shaped cushion 120A is affixed to one side of a fastening material 122 A (e.g., a pad), while the opposing side of the fastening material 122A is adapted to removably couple to the treatment site-engaging surface 105A, for example, via a hook-and-loop engagement, an adhesive, or any other suitable mechanism for reversible attachment.

[0039] FIGS. 2 A and 2B show a similar bunion split assembly 100B designed for the right foot, which is effectively a mirror image of the bunion splint assembly 100A. Similarly labeled components labeled as “B” in FIGS. 2A and 2B correspond to the components labeled as “A” in FIGS. 1 A and IB.

[0040] FIGS. 3A, 3B, and 3C show top-down, side, and blown-up views, respectively, of the exemplary ring-shaped cushion 120 A and fastening material 122 A. In at least one embodiment, the ring-shaped cushion 120A has a tapered outer diameter that is largest at the interface with the fastening material 122 A, as illustrated in FIG. 3B. In at least one embodiment, the ring-shaped cushion 120A comprises a polymer gel or a foam material. In at least one embodiment, the ringshaped cushion 120A defines an elongated aperture having a first inner diameter that is greater than an orthogonal second inner diameter, and wherein the first inner diameter is from about 2.5 cm to about 5 cm.

[0041] FIG. 4 illustrates a method of applying the bunion splint assembly 100B to a left human foot in accordance with at least one embodiment. As shown, the wearer stands on the inner surface 103B of the flexible body 10 IB while wrapping a big toe fastener around the inside of the big toe and affixing the strap 112B. Before wrapping the foot, the ring-shaped cushion 122B can be positioned on the treatment site-engaging surface 105B so that it will surround the outside of the bunion when engaged, illustrated in FIG. 5. Once wrapped around the foot and secured thereto, the ring-shaped cushion 120B encompasses the bunion and redistributes force exerted by the elongated rigid member 114B around bunion without the ring-shaped cushion 120B or another portion of the bunion splint assembly 100B applying a force to the center portion of the bunion. [0042] FIGS. 6 A and 6B show different perspective views of the bunion splint assembly 100B when worn on a right human foot in accordance with at least one embodiment, which illustrate the placement of straps to secure the bunion splint assembly 100B to the foot. In at least one embodiment, the strap 112B is adapted to wrap at least partially around the big toe and be reversibly secured to an outer surface 102B of the flexible body 10 IB. In at least one embodiment, the straps 104B and HOB are disposed along a common edge (e.g., the seam 106B) of the flexible body 10 IB and are adapted to reversibly engage each other and secure the flexible body 101B to the heel. In at least one embodiment, the strap 108B is adapted to be reversibly secured to the outer surface 102B of the flexible body 10 IB on a top portion and/or side portion of the foot. In at least one embodiment, the inner surface 103B (not shown in FIGS. 6 A and 6B) is formed from a different material than the outer surface 102B. For example, the inner surface 103B may be formed from a material such as a polyblend stretch terry cloth fabric, or other suitable material that avoids irritating the skin during prolonged contact. The outer surface 102B may be formed, for example, from a stretch polyester knap fabric, or other suitable material adapted to reversibly engage a hook-and-loop fastener material of the straps.

[0043] In at least one embodiment, a kit is contemplated, which may include one or more or more bunion splint assemblies as described herein. For example, the kit includes a single bunion splint assembly for each of the left foot and the right foot.
