FIG. 1 is a perspective view of an exampleorthotic support assembly 10 for positioning around a patient's foot, which includes a first, internal device or insert 12 (as shown inFIG. 2 ) and a second,external device 14. In one embodiment, theinternal device 12 forms an orthotic support device (e.g., a boot, a cushioning material) and is made of a soft, pliable material (e.g., foam, gel) that surrounds the foot and is secured to the foot through one or more fasteners (e.g., hook and loop, buttons). Theinternal device 12 can conform to the shape of the foot based on the material selected and fasteners can be used to secure theinternal device 12 to the foot. Surrounding theinternal device 12 is theexternal device 14, which can be formed of a second, lightweight material (e.g., plastic) that is more rigid than theinternal device 12. Theinternal device 12 wraps or envelopes the patient foot and removes excess tolerance between theexternal device 14 and the foot of the patient, ultimately assisting in limiting and/or preventing relative movement between the foot and theexternal device 14. During use, thedevice 12 is compressed between the patient's foot and an internal surface of theexternal device 14. - In one embodiment, the
external device 14 is a walking boot, formed of one or moreouter shell components 16 and aninner cushioning layer 18. Theexternal device 14 can further include one ormore fasteners 20 that assist in securing theassembly 10 to the foot. In one embodiment, theexternal device 14 is a walking boot, shoe cast, foot support, foot brace or other similar orthotic device that at least partially immobilizes the patient's foot, yet still allows the patient to walk, stand or engage in other activity. - With reference to
FIG. 2 ,internal device 12 includes alower portion 40 and anupper portion 42. In one embodiment, theinternal device 12 is formed of foam and can be of different selected thicknesses as desired, such as any thickness such as 1/16, ⅛, ¼, ½ inches or other thicknesses. The lower portion 40 (extending horizontally whenassembly 10 is in an upright position) is configured to be positioned about a patient's forefoot and midfoot, while the upper portion 42 (extending vertically whenassembly 10 is in an upright position) is configured to be positioned about a patient's hindfoot and ankle.Fasteners 44 can be used to secure thelower portion 40 and theupper portion 42 to a patient's foot. Asupplemental cushioning layer 46 can be coupled with the internal device 12 (e.g., using an adhesive) to increase a thickness of theinternal device 12 proximate an area (e.g., near a wound) of the foot that may be useful in treating a wound such as a diabetic ulcer. In other embodiments,supplemental cushioning layer 46 can be eliminated. -
FIG. 3 is a flow diagram of amethod 100 for use in treating wounds (e.g., diabetic ulcers) usingassembly 10.Method 100 begins atstep 102, wherein a walking boot and insert are selected based on the patient. Various types and styles of walking boots can be selected based on several characteristics such as size and performance. Additionally, an insert can be selected based on various characteristics such as size, performance, thickness, wound location and others. One or more cushioning layers can also be applied to the insert at theselection step 102. Once the walking boot and insert are selected, a position of the wound on the patient's foot are identified with respect to the insert atstep 104. Although theexample method 100 is described with respect to one wound, other embodiments include accommodation of multiple wounds on a patient's foot. Common locations for wounds can include the heel, forefoot, either side of the foot and other locations. - Based on the position identified of the wound, a portion of the insert is removed at
step 106. In one embodiment, the portion is cut from the insert such that the wound can be accommodated. As illustrated inFIGS. 4 and 5 ,insert 12 is cut to define anopening 22. The opening which is configured to surround a wound on the patient's foot. Once the portion is removed from the insert, the insert is secured to the patient atstep 108. In one embodiment, the insert is secured by positioning the opening 22 around a wound of the patient and attaching thefasteners 44 around the patient's foot. The insert 12 wraps around the patient's foot, with portions of theinsert 12 surrounding the top, bottom and sides of the foot. Once the insert is secured to the patient, the walking boot is then secured to the patient's foot around the insert atstep 110. - With reference to
FIGS. 6 and 7 , theopening 22 creates an interior volume V within theassembly 10, effectively removing excess tolerance between the foot F and theexternal device 14 while suspending the wound W so that theexternal device 14 can be utilized conventionally as the wound W heals. The volume V is bound by anedge surface 24 of the opening, asurface 26 of the skin of the foot inbound of theedge surface 24 and asurface 28 of theinner cushioning layer 18 of theexternal device 14 inbound of theedge surface 24. The interior volume V can be bound by at least one side of the foot F, at least two sides of the foot F, at least three sides of the foot F or all sides of the foot. In the embodiment illustrated, the interior volume V is bound by two sides of the foot F, namely a portion of a sole of the foot F (i.e., the bottom) and a portion of a muscular lateral ridge of the foot F (i.e., the outer side). In other embodiments, the volume V can include the bottom, the bottom and the inner side, the inner side and the top side, the outer side and the top side, the bottom, inner and outer sides, the top, inner and outer sides, or all sides. In further embodiments, multiple openings can be positioned within theinternal device 12. - Due to the presence of volume V, wound W is suspended within the
assembly 10 and protected from contact withcushioning layer 18 during use of theassembly 10 while a patient walks, stands or engages in other activity. A thickness of theinternal insert 12 can be selected to ensure that ample space exists between the outer surface of the skin and the internal surface of thecushioning layer 18. In one embodiment, the thickness of theinsert 12 is at least ⅛ inch, at least ¼ inch, at least ⅓ inch, at least ⅜ inch, at least ½ inch, at least ⅝ inch, at least ¾ inch, greater than ¾ inch, between ⅛ and 1 inch and other thicknesses. In addition, a size of the opening (as defined by the edge surface 24) can be selected to provide ample space surrounding the wound W. As a result, forces placed on the foot F during walking, standing or other activity are distributed throughout theinternal device 12, while the wound W is exposed to little or no forces. - In the illustrated embodiment,
opening 22 is positioned in thelower portion 40 and configured to surround a wound on an outer side of the patient's foot. Theopening 22 is defined by theedge surface 24, which extends along a thickness of theinternal device 12. In addition, and as illustrated inFIG. 4 , asupplemental cushioning layer 46 can be coupled with the internal insert 12 (e.g., using an adhesive) to increase a thickness surrounding the wound W and increase a size of the internal volume V. As a result, the wound W is suspended within the internal volume V. Forces on the walking boot are distributed about theassembly 10 and away from the wound W. - In one embodiment,
internal insert 12 is customized usingmethod 100 in a clinical setting at a medical office, whereby theinternal insert 12 is accessed without the opening 22 positioned therein. A practitioner can measure a size of the wound W and locate a position on theinternal device 12 relative to the wound W when theinternal device 12 is worn by the patient. The practitioner can then cut (e.g., using a scissors, knife) the opening 22 such that the wound W can be accommodated wheninternal device 12 is positioned on the patient's foot. Afterinternal device 12 is positioned on the patient's foot,external device 14 can be positioned on the patient's foot, creating interior volume V, which allows exposure of wound W without forces that would undesirably hinder healing of the wound W. - Various embodiments of the invention have been described above for purposes of illustrating the details thereof and to enable one of ordinary skill in the art to make and use the invention. The details and features of the disclosed embodiment[s] are not intended to be limiting, as many variations and modifications will be readily apparent to those of skill in the art. Accordingly, the scope of the present disclosure is intended to be interpreted broadly and to include all variations and modifications coming within the scope and spirit of the appended claims and their legal equivalents.
