Abstract
A filament retaining washer for mounting about the shank of a bone screw deployed in a bone whereby to retain the filament to the bone, the filament retaining washer comprising a structure having a screw hole extending therethrough for receiving therein the shank of the bone screw deployed in the bone, whereby to secure the structure to the bone, the screw hole defining a first axis, and the structure having a filament hole extending therethrough for receiving a filament therein so as to retain the filament to the structure, the filament hole defining a second axis extending substantially perpendicular to the first axis.
Claims44
A filament retaining washer for mounting about the shank of a bone screw deployed in a bone whereby to retain the filament to the bone, said filament retaining washer comprising:
- a structure having a screw hole extending therethrough for receiving therein the shank of the bone screw deployed in the bone, whereby to secure said structure to said bone, said screw hole defining a first axis, and said structure having a filament hole extending therethrough for receiving a filament therein so as to retain said filament to said structure, said filament hole defining a second axis extending substantially perpendicular to said first axis, with said second axis being aligned with a bone screw extending through the screw hole.
A filament retaining washer for mounting about the shank of a bone screw deployed in a bone whereby to retain the filament to the bone, said filament retaining washer comprising:
- a body;
- a downwardly projecting extension connected to said body and having a screw hole extending therethrough for receiving therein the shank of the bone screw deployed in the bone, whereby to secure said downwardly projecting extension to said bone, said screw hole defining a first axis;
- and
- an upwardly projecting extension connected to said body and having a filament hole extending therethrough for receiving a filament therein so as to retain said filament to said upwardly projecting extension, said filament hole defining a second axis extending substantially perpendicular to said first axis, with said second axis being aligned with a bone screw extending through the screw hole.
A system for securing an object to a bone, said system comprising:
- a bone screw;
- a washer comprising:
- a body;
- a downwardly projecting extension connected to said body and having a screw hole extending therethrough for receiving therein the shank of said bone screw deployed in the bone, whereby to secure said downwardly projecting extension to said bone, said screw hole defining a first axis, with said second axis being aligned with a bone screw extending through the screw hole;
- and
- an upwardly projecting extension connected to said body and having a filament hole extending therethrough, for receiving a filament therein so as to retain said filament to said upwardly projecting extension, said filament hole defining a second axis extending substantially perpendicular to said first axis;
- and
- a filament received by said filament hole, said filament securing the object to said bone.
A method for securing an object to a bone, said method comprising:
- providing a screw, a filament and a suture retaining washer, said suture retaining washer comprising:
- a body;
- a downwardly projecting extension connected to said body and having a screw hole extending therethrough for receiving therein the shank of a bone screw deployed in the bone, whereby to secure said downwardly projecting extension to said bone, said screw hole defining a first axis;
- and
- an upwardly projecting extension connected to said body and having a filament hole extending therethrough for receiving a filament therein so as to retain said filament to said upwardly projecting extension, said filament hole defining a second axis extending substantially perpendicular to said first axis, with said second axis being aligned with a bone screw extending through the screw hole;
- securing said washer to the bone with said screw, with said filament extending through said filament hole;
- and
- using said filament to secure the object to the bone.
A method for securing an object to a bone, said method comprising:
- providing a screw, a filament and a suture retaining washer, said suture retaining washer comprising:
- a structure having a screw hole extending therethrough for receiving therein the shank of the bone screw deployed in the bone, whereby to secure said structure to said bone, said screw hole defining a first axis, and said structure having a filament hole extending therethrough for receiving a filament therein so as to retain said filament to said structure, said filament hole defining a second axis extending substantially perpendicular to said first axis, with said second axis being aligned with a bone screw extending through the screw hole;
- securing said washer to the bone with said screw, with said filament extending through said filament hole;
- and
- using said filament to secure the object to the bone.
A filament retaining washer for mounting about the shank of a bone screw deployed in a bone whereby to retain the filament to the bone, said filament retaining washer comprising:
- a body;
- a downwardly projecting extension connected to said body and having a screw hole extending therethrough for receiving therein the shank of the bone screw deployed in the bone, whereby to secure said downwardly projecting extension to said bone, said screw hole defining a first axis;
- and
- an upwardly projecting extension connected to said body and having a filament hole extending therethrough for receiving a filament therein so as to retain said filament to said upwardly projecting extension, said filament hole defining a second axis extending substantially perpendicular to said first axis, with said upwardly projecting extension being displaced laterally and longitudinally from said downwardly projecting extension.
A filament retaining washer for mounting about the shank of a bone screw deployed in a bone whereby to retain the filament to the bone, said filament retaining washer comprising:
- a structure having a screw hole extending therethrough for receiving therein the shank of the bone screw deployed in the bone, whereby to secure said structure to said bone, said screw hole defining a first axis, and said structure having a filament hole so as to retain said filament to said structure, said filament hole defining a second axis extending substantially perpendicular to said first axis, with said second axis extending parallel to a third axis extending through said first axis.
