Abstract

An orthopedic device as in a dorsal splint for treating plantar fasciitis includes a substantially rigid splint member having an overmolded flexible edge and living hinges, or substantially rigid component pieces received in a flexible member, to provide improved and more comfortable fitting to a user and reduced storage requirements. The splint member is shaped and configured to engage the dorsal aspects of a user's lower leg, ankle, and foot. A soft-good strap system is provided to maintain the dorsal splint in position and has suitable padding to treat various foot conditions.

Claims (28)

1. An orthopedic device, comprising:

a splint member being substantially rigid and formed from a thermoplastic or thermosetting polymer, the splint member defining anterior and posterior surfaces, the splint member having an original shape wherein the splint member defines along a length of the splint member an upper portion, an intermediate portion and a lower portion, and in the original shape the posterior surface of the splint member has a concave shape along the length of the splint member and at least in the intermediate and upper portions, and the splint member has rigid edges which are hard;

an edge overmold being flexible and integrally secured along at least a portion of the rigid edges of the splint member, the edge overmold extending outwardly from the periphery of the splint member and having greater flexibility than the splint member;

a stay being formed from a bendable aluminum metal embedded in the splint member between the anterior and posterior surfaces and within the intermediate portion of the splint member, the stay arranged to maintain a shape when the orthopedic device is worn by a wearer, and wherein the stay is bendable to place the splint member into a modified shape different from the original shape;

wherein the splint member and the stay form a bend area located only within the intermediate portion of the splint member such that the stay is bendable at the bend area in order to custom-fit or modify a therapeutic angle of the splint member within the intermediate portion by arranging the upper and lower portions relative to one another;

wherein the original shape defines an original angle of the upper portion relative to the lower portion along the length within the range of 80° to 90°, and the therapeutic angle is defined as being the same as or different from the original angle and within the range of 80° to 90°.

2. The orthopedic device according to claim 1 , wherein the intermediate portion defines an upper neck and a lower neck, and a bulbous width portion located between the upper and lower necks which each reduce material of the width of the intermediate portion relative to the bulbous width portion, the bulbous width portion generally corresponding to the bend area and symmetrically extends outwardly in width within first and second sides delimited by the rigid edges of the intermediate portion.

3. The orthopedic device according to claim 2 , wherein the edge overmold forms flaps on opposed sides along peripheries of the upper and lower necks having a larger portions than at the bulbous width portion.

4. The orthopedic device according to claim 1 , wherein the splint member defines a recessed portion located around the bend area and arranged for facilitating bending of the stay, wherein the recessed portion is defined along the anterior surface of the splint member between rigid edges of the intermediate portion.

5. The orthopedic device according to claim 1 , wherein a shape configuration of the lower portion remaining substantially the same as the stay is bent.

6. The orthopedic device according to claim 1 , wherein the stay is more rigid than the splint member.

7. The orthopedic device according to claim 1 , wherein the orthopedic device includes at least one opening extending through a thickness of the splint member and the stay.

8. The orthopedic device according to claim 1 , wherein the stay continuously extends along a length and through the upper, intermediate and lower portions of the splint member.

9. The orthopedic device according to claim 1 , wherein the stay slightly bulges along lines formed by the intermediate portion and along the posterior surface of the orthopedic device within the concave shape.

10. An orthopedic device, comprising:

a splint member being substantially rigid and formed from a thermoplastic or thermosetting polymer, the splint member defining anterior and posterior surfaces, and peripheral surfaces, the splint member having an original shape wherein the splint member defines along a length of the splint member an upper portion, an intermediate portion and a lower portion, and in the original shape the posterior surface of the splint member has a concave shape and at least in the intermediate and upper portions along the length of the splint member, and the splint member has rigid edges which are hard;

a stay being bendable aluminum metal embedded in the splint member between the anterior and posterior surfaces and within the intermediate portion of the splint member, the stay arranged to maintain a shape when the orthopedic device is worn by a wearer, and wherein the stay is bendable to place the splint member into a modified shape different from the original shape;

wherein the splint member and the stay collectively form a bend area located only within the intermediate portion of the splint member such that the stay is bendable at the bend area in order to custom-fit or modify a therapeutic angle of the splint member within the intermediate portion by arranging the upper and lower portions relative to one another;

wherein the original shape defines an original angle of the upper portion relative to the lower portion along the length within the range of 80° to 90°, and the therapeutic angle is defined as being the same as or different from the original angle and within the range of 80° to 90°.

11. The orthopedic device according to claim 10 , wherein the lower portion defines a flared distal end portion.

12. The orthopedic device according to claim 11 , wherein the lower portion defines venting through slots extending through the entirety of the splint member.

13. The orthopedic device according to claim 10 , wherein the stay slightly bulges along lines formed by the intermediate portion and along the posterior surface of the orthopedic device within the concave shape.

14. The orthopedic device according to claim 10 , wherein the intermediate portion defines an upper neck and a lower neck, and a bulbous width portion located between the upper and lower necks which each reduce material of the width of the intermediate portion relative to the bulbous width portion, the bulbous width portion generally corresponding to the bend area and symmetrically extends outwardly in width within first and second sides delimited by the rigid edges of the intermediate portion.

15. An orthopedic device, comprising:

a splint member being substantially rigid and formed from a thermoplastic or thermosetting polymer, the splint member defining anterior and posterior surfaces, the splint member having an original shape, wherein the splint member defines along a length of the splint member an upper portion, an intermediate portion and a lower portion, and in the original shape the posterior surface of the splint member has a concave shape, and the splint member has rigid edges which are hard;

an edge overmold being flexible and integrally secured along at least a portion of the rigid edges of the splint member, the edge overmold extending outwardly from the periphery of the splint member and having greater flexibility than the splint member;

a stay being formed from a bendable aluminum metal embedded in the splint member between the anterior and posterior surfaces and within the intermediate portion of the splint member, the stay arranged to maintain a shape when the orthopedic device is worn by a wearer, and wherein the stay is bendable to place the splint member into a modified shape different from the original shape;

wherein the edge overmold extends along the hard and rigid edges at the upper and intermediate portions of the splint member, the lower portion defines a flared distal end portion devoid of the edge overmold.
