Claims14
A hand orthosis configured to treat Dupuytren's contracture comprising a glove and at least one finger splint, wherein the at least one finger splint is configured to be fixed to a hand and positioned by means of the glove, characterized in that the at least one finger splint comprises at least one spring;
- wherein the at least one finger splint is configured to extend in a utilization position of the hand orthosis from a metacarpus, over a metacarpophalangeal joint, a proximal phalanx and a middle joint at least to a middle phalanx of an assigned finger;
- wherein the at least one spring is configured to be doubly bent in an area of the proximal phalanx between the metacarpophalangeal joint and the middle joint of the assigned finger so that the at least one spring has a rigid middle region, from which a first elastic distal area is configured to extend in a direction of the metacarpus and a second elastic distal area is configured to extend in a direction of the middle joint of the assigned finger;
- wherein the at least one spring is configured to have an arched shape, with a curvature transverse to a longitudinal direction of the at least one finger splint and is configured to place the assigned finger under tensile stress in a bending position with the rigid middle region configured to lay against and be supported by the proximal phalanx by means of the glove and wherein the first elastic distal area is configured to form a first bridge over and be spaced apart from at least the middle joint and wherein the second elastic distal area is configured to form a second bridge over and be spaced apart from at least the metacarpophalangeal joint.

- wherein the at least one finger splint is configured to extend in a utilization position of the hand orthosis from a metacarpus, over a metacarpophalangeal joint, a proximal phalanx, and a middle joint at least to a middle phalanx of an assigned finger;
- characterized in that the at least one finger splint is configured to have a finger plate positioned in the area of the proximal phalanx of the assigned finger by means of the glove, wherein at least one first and at least one second spring are arranged on the finger plate, and wherein the at least one first spring is configured to extend in a direction of the metacarpus and the at least one second spring is configured to extend in a direction of the middle phalanx of the assigned finger;
- wherein the springs are configured to have an arched shape, with a curvature transverse to a longitudinal direction of the at least one finger splint and to place the assigned finger under tensile stress in a bending position with the finger plate configured to lay against and be supported by the proximal phalanx, and wherein the at least one first spring is configured to form a first bridge over and be spaced apart from at least the middle joint and the at least one second spring is configured to form a first bridge over and be spaced apart from at least the metacarpophalangeal joint.
