Abstract
A device for repairing Hallux Valgus (HV) is disclosed comprising a first arm adapted to be affixed inside the canal of the first metatarsus (1MT) of a human foot, a second arm adapted to be affixed inside the canal of the second metatarsus (2MT) of a human foot and a spring mechanism connected between the first arm and the second arm, active to push the 1MT closer to the 2MT. The device may comprise fixating means adapted to fixate said first arm inside said MT and said second arm inside said 2MT and the spring mechanism is removable from the first and the second arms.
Claims5
A device for repairing Hallux Valgus (HV) comprising:
- a. a first arm adapted to be longitudinally disposed in the first metatarsus (1MT) of a human foot;
- b. a second arm adapted to be longitudinally disposed in the second metatarsus (2MT) of a human foot;
- and
- c. a spring mechanism interconnecting said first arm and said second arm, operable to draw said 1MT and 2MT together;
- wherein at least one of said arms further comprises fixing means adapted for fixation of said first and/or second arm inside the canal of the respective first and/or second metatarsus;
- and
- wherein said spring mechanism comprises first and second extending portions that provide a first spring force between said first and said second arms about a pivot point in a first plane being the plane common to said 1MT and 2MT and a second spring force, less than the first spring force, between said 1MT and 2MT in a second plane not coincident with said first plane.
A device for repairing Hallux Valgus (HV) comprising:
- a. a first arm adapted to be longitudinally disposed in the first metatarsus (1MT) of a human foot;
- b. a second arm adapted to be longitudinally disposed in the second metatarsus (2MT) of a human foot;
- and
- c. a spring mechanism interconnecting said first arm and said second arm, operable to draw said 1MT and 2MT together;
- wherein at least one of said first and second arms is shaped in a longitudinal tubular arc-like manner for fixation of said first and/or second arm inside the canal of the respective first and/or second metatarsus;
- said arm is provided with a gripping point connecting said spring mechanism thereto.
A device for repairing Hallux Valgus (HV) comprising:
- a first arm adapted to be affixed inside the canal of the first metatarsus (1MT) of a human foot;
- a second arm adapted to be affixed inside the canal of the second metatarsus (2MT) of a human foot;
- and a spring mechanism interconnecting said first arm and said second arm, adapted to draw said first and second arms together;
- wherein
- at least one of said arms comprises a curved elongated member adapted to be longitudinally disposed in and fitted snugly in zone 3 of a medullary canal of 1MT or 2 MT and having a curved and tapered tip for insertion longitudinally in the medullary canal;
- and wherein
- the spring mechanism comprises first and second spring attachments, each adapted to be attached at a respective attachment end thereof to the respective first and second arms, and a spring between the first and second spring attachments and opposite the attachments ends of the first and second arms.
