Abstract
A fixation device for connecting a stabilization device to a bone comprises a first member comprising a first portion for attachment to a bone; a second member comprising a second portion for attachment to a bone and connected to the first member by a pivotal connection such that the first and second portions are spaced apart by an adjustable distance, at least one of the first and second members further comprising a portion for mounting a connector adapted to secure a stabilization device.
Claims11
A variable geometry occipital fixation device, comprising:
- a first lateral member having a proximal end, a distal end, a pivot bore located at the proximal end, and an attachment bore located at the distal end;
- a second lateral member having a proximal end, a distal end, a pivot bore located at the proximal end, and an attachment bore located at the distal end;
- and
- a single-piece midline member having a proximal end, a distal end, a pivot bore located at the proximal end, and a fixation bore located at the distal end, wherein the distal end of the first lateral member is thicker than the proximal end of the first lateral member, wherein the distal end of the second lateral member is thicker than the proximal end of the second lateral member, and wherein the distal end of the midline member is thicker than the proximal end of the midline member, wherein in forming the variable geometry occipital fixation device, the proximal ends of the first lateral member, the second lateral member, and the midline member are stacked on top of each other along a common axis extending through the pivot bores of the first lateral member, the second lateral member, and the midline member such that a thickness of the variable geometry fixation device is substantially uniform across the first lateral member, the second lateral member, and the midline member, and wherein the first lateral member, the second lateral member, the midline member, or a combination thereof is rotatable about the common axis.
