Abstract
The present invention relates to a bone support device for supporting fragments of bone, in particular of fractured bones of the human body. The device includes a first member adapted to be connected to a bone fragment, a second member adapted to be connected to another bone fragment, and an adjustable articulated central body connected to the first and second members. The device allows to adjust the relative position of the two bones.
Claims29
A bone support device for supporting bone fragments, comprising a first member adapted to be rigidly connected to the first of said bone fragments, a second member adapted to be rigidly connected to the second of said bone fragments, and an adjustable articulated central body connected to said first member and to said second member, said articulated central body facilitating the adjustment of the position of said first member with respect to said second member and facilitating the rigidly locking of said position;
- said articulated central body comprising:
- first articulation means which allow the rotation of said first member and of said second member on a first articulation plane;
- second articulation means which allow the rotation of said first member and of said second member on a second articulation plane;
- fourth articulation means to allow the rotation of said first member with respect to said second member about an axis which is substantially parallel to the axis of said bone fragments;
- said first articulation means and said second articulation means being adjustable and lockable independently of one another, so that the rotation of said first member and of said second member on said first articulation plane and on said second articulation plane can be independently adjusted for each of said articulation planes and the adjustment of said first articulation plane does not interfere with the adjustment of said second articulation plane and vice versa;
- said first articulation means comprising a first pair of hinges, each hinge allowing a single degree of freedom of rotation, one hinge being connected to said first member, the other being connected to said second member;
- said second articulation means comprising a second pair of hinges, each hinge of said second pair of hinges having a single degree of freedom of rotation and being connected directly to said first articulation means;
- said fourth articulation means mutually connecting the elements of said second pair of hinges.

- said articulated central body comprising:
- first articulation means which allow the rotation of said first member and of said second member on a first articulation plane;
- second articulation means which allow the rotation of said first member and of said second member on a first articulation plane;
- second articulation means which allow the rotation of said first member and of said second member on a second articulation plane;
- fourth articulation means to allow the rotation of said first member with respect to said second member about an axis which is substantially parallel to the axis of said bone fragments;
- said first articulation means and said second articulation means being adjustable and lockable independently of one another, so that the rotation of said first member and of said second member on said first articulation plane and on said second articulation plane can be independently adjusted for each of said articulation planes and the adjustment of said first articulation plane does not interfere with the adjustment of said second articulation plane and vice versa;
- said first articulation means comprising a first pair of hinges, each hinge allowing a single degree of freedom of rotation, one hinge being connected to said first member, the other being connected to said second member;
- said second articulation means comprising a second pair of hinges, each hinge of said second pair of hinges having a single degree of freedom of rotation and being connected directly to said first articulation means;
- said fourth articulation means mutually connecting said first member and said first articulation means.

- said articulated central body comprising:
- first articulation means which allow the rotation of said first member and of said second member on a first articulation plane;
- second articulation means which allow the rotation of said first member and of said second member on a second articulation plane;
- said first articulation means and said second articulation means being adjustable and lockable independently of one another, so that the rotation of said first member and of said second member on said first articulation plane and on said second articulation plane can be independently adjusted for each of said articulation planes and the adjustment of said first articulation plane does not interfere with the adjustment of said second articulation plane and vice versa;
- said articulated central body comprising six individually lockable degrees of freedom.
