Abstract

An orthosis can comprise a first body member that can conform to a portion of a patient'"'"'s body and a second body member that can conform to another portion of a patient'"'"'s body. A closure unit having a first connector member with a first plurality of support posts can be operatively connected to the first body member, while a second connector member with a second plurality of support posts can be operatively connected to the second body member. An elongated flexible pull member can operatively extend between the respective first and second support posts so that when tightened by a patient, a pull member slides across the support posts to provide a mechanical force advantage to draw the first body member and the second body member against the patient'"'"'s torso. A closure unit can be of a modular configuration for subjective mounting on various components of an orthosis to provide a highly adaptable closure unit.

Claims

1. A modular orthosis for the progressive treatment of a patient, comprising:

a first orthosis having a front body member conforming to a portion of a patient'"'"'s torso, and a rear body member conforming to another portion of a patient'"'"'s torso, the rear and front body members are operatively positioned to provide relative movement for compression of the patient'"'"'s torso pursuant to a first course of treatment; and

wherin the first connector member has a first plurality of support posts, a second connector member has a second plurality of support posts operatively connected to the second body member, and an elongated flexible pull member operatively extending between the respective first and second support posts to provide a mechanical advantage when tightened by the patient to draw the first body member and second body member against the patient'"'"'s torso to provide compression of the patient'"'"'s torso.

2. The modular orthosis of claim 1 wherein the support posts are plastic.

3. The modular orthosis of claim 1 wherein the first connector member includes an upper housing member and a lower housing member operatively connected together and interconnected by the plurality of support posts.

4. The modular orthosis of claim 3 wherein the upper housing member and the lower housing member are relatively flexible plastic plates.

5. The modular orthosis of claim 4 further including at least one pull member guide.

6. The modular orthosis of claim 3 wherein the lower housing member is a bendable metal plate.

7. The modular orthosis of claim 3 wherein the plurality of support posts are rivets.

8. The modular orthosis of claim 7 wherein a chrome plated steel sleeve is fixed to each rivet.

9. The modular orthosis of claim 3 wherein the elongated flexible pull member is a cord.

10. The modular orthosis of claim 9 further including a fastener member connected to both ends of the cord for attachment to one of the first and second body members.

11. The modular orthosis of claim 3 wherein the elongated flexible pull member is a braided nylon cord.

12. The modular orthosis of claim 1 wherein the configuration of the first connector member and the second connector member is complimentary to enable their respective support posts to overlap a common axis.

13. The modular orthosis of claim 12 wherein the respective first and second connector members have intermeshing surfaces when overlapping the common axis.

14. The modular orthosis of claim 13 where the intermeshing surfaces have an undulating appearance.

15. The modular orthosis of claim 12 wherein the first and second plurality of support posts have axes extending approximately perpendicular to the surface of the second body member.

16. The modular orthosis of claim 1 further including an elastic band member interconnected between the first and second connector members to cover an exterior side of the flexible pull member.

17. The modular orthosis of claim 16 further including a hook material on the elastic band member to adhere the elastic band member to the rear body member.

18. The modular orthosis of claim 16 wherein the rear body member has a plastic housing with a soft foam liner.

19. The modular orthosis of claim 1 wherein the front body member has a plastic housing with a soft foam liner.

20. The modular orthosis of claim 1 wherein the front body member has an exterior with a nap material to enable a removable connection with the first body member and the second body member.

21. A lumbo-sacral orthosis comprising:

a first orthotic assembly having a first front body member conforming to a portion a patient'"'"'s torso;

a second back body member conforming to a portion of a patient'"'"'s torso, the combination of the first front member and second back member providing a first orthotic for stabilizing a patient'"'"'s torso, the first front member includes a flexible body member having a pocket to receive a relatively rigid insert, an exterior of the pocket has a nap surface texture; and

a closure unit for providing a mechanical advantage to exert a compressive force on the patient'"'"'s torso by drawing the first front body member and second back body member together, the closure unit includes a first body member and a second body member of a configuration to extend about at least a portion of the first front body member and the second back body member, the first body member has a first pocket member to receive a first stay member and the second body member has a second pocket member to receive a second stay member, a first connector member having a first support housing with a first plurality of support posts that can be operatively connected to the first body member, the first plurality of support posts are fixed and have axes which would extend approximately perpendicular to the surface of the patient and are spaced and aligned to be respectively cantilevered, a second connector member having a second support housing with a second plurality of support posts that can be operatively connected to the second body member, the second plurality of support posts are fixed and have axes which would extend approximately perpendicular to the surface of the patient and are spaced and aligned to be respectively cantilevered, the first and second connector members include surfaces of a hook texture, and the first body member and second body member include surfaces of a nap texture to provide an adjustable fastening attachment with the hook texture surfaces of the first and second connector members, the first body member and the second body member include hook texture surfaces for removably engaging the first front member nap surface, and an elongated flexible pull member operatively extending for sliding movement directly between the respective first and second support posts to provide a mechanical force advantage when tightened by the patient to draw the first body member and second body member to exert a compressive force against the patient'"'"'s body, the closure unit providing a second orthotic assembly for exerting a compressive force through the first body member and second body member when removed from the first orthotic assembly.

22. The lumbo-sacral orthosis of claim 21, whereby the respective axes are juxtapositioned to be movable so that the first plurality of support posts can be placed on one side of the second plurality of support posts during assembly to receive the elongated flexible pull member and placed on another side of the second plurality of support posts during operation to provide a mechanical force advantage.
