Abstract

A dorsal night splint has dynamic adjustable features that allow the patient to adjust the splint while in use to control the stretching of the plantar fascia and Achilles. A semi-rigid flexible frame is included along with a tightening strap that is anchored to the frame and by which the patient can tension the strap and adjust the structure of the frame to fit the patient's desired therapeutic or prophylactic needs.

Claims (22)

1. A method for applying a splint to stretch a wearer's plantar fascia, comprising:

securing a first portion of the splint to the wearer's lower leg with a first attaching strap, the first portion comprising a first receptacle;

securing a second portion of the splint to the wearer's lower leg with a second attaching strap, the second portion comprising a second receptacle;

wrapping at least a portion of a soft housing attached to the splint around a dorsal side of the wearer's foot to anchor the splint to the wearer's lower leg; and

adjusting a tightening strap that passes through the first receptacle and through the second receptacle by pulling a distal portion of the tightening strap extending out of the second receptacle toward the wearer,

wherein:

an adjustable forefoot strap extends distally, continuously and inseparably over the front of the wearer's toes between a first end secured to the soft housing under the wearer's toes, and a second end coupled directly to the distal portion of the tightening strap via a d-ring such that pulling the distal portion of the tightening strap toward the wearer simultaneously flexes a bend portion of the splint that spans between the first and second portions, stretches the wearer's plantar fascia, and anchors the forefoot strap to the tightening strap in tension over the front of the wearer's toes.

2. The method of claim 1 , wherein the splint comprises first and second hinged flaps extending along lateral and medial edges, respectively, of the splint.

3. The method of claim 2 , wherein the second receptacle is spaced between the first and second hinged flaps along the second portion.

4. The method of claim 2 , wherein the first and second hinged flaps are co-molded and integral with the splint.

5. The method of claim 1 , wherein adjusting the tightening strap comprises securing a distal end of the splint.

6. The method of claim 5 , wherein the distal end of the splint is secured to the tightening strap by engaging a hook and loop mechanism.

7. The method of claim 1 , wherein the splint includes a flap extending vertically along a side edge and attached to the side edge by a hinge.

8. The method of claim 7 , wherein the flap includes a slot configured to receive a portion of the soft housing, the slot conforming to the wearer's leg.

9. The method of claim 1 , wherein the tightening strap has a first end configured to anchor to one of the first and second portions of the splint.

10. The method of claim 9 , wherein pulling the distal portion of the tightening strap draws the first portion of the splint toward the second portion of the splint.

11. The method of claim 1 , wherein the splint further comprises a forefoot support pad configured to be disposed between the wearer's toes and the soft housing.

12. The method of claim 11 , wherein the forefoot support pad includes a distal lift area configured to fit under the wearer's toes and a proximal support area configured to fit behind the ball of the wearer's foot, wherein the distal lift area is thicker than the proximal support area.

13. The method of claim 1 , wherein the first portion of the splint is configured to be applied along an anterior side of the wearer's foot and the second portion of the splint is configured to be applied along an anterior side of the wearer's lower leg.

14. The method of claim 1 , wherein the soft housing is configured to fit under the wearer's foot.

15. The method of claim 1 , wherein the tightening strap forms a pulley having a first section, a second section, and a fold between the first and second sections.

16. The method of claim 1 , wherein the splint further comprises a space between the tightening strap and the bend portion.
