1. An occipital fixation method, comprising:
- providing a variable geometry occipital fixation device, wherein the variable geometry occipital fixation device comprises a first lateral member, a second lateral member, and a midline member, wherein the first lateral member comprises a proximal end, a distal end, a pivot bore located at the proximal end, and an attachment bore located at the distal end, wherein the second lateral member comprises a proximal end, a distal end, a pivot bore located at the proximal end, and an attachment bore located at the distal end, wherein the midline member comprises a proximal end, a distal end, a pivot bore located at the proximal end, and a fixation bore located at the distal end, and wherein the first lateral member, the second lateral member, and the midline member are coupled together at their proximal ends along a common axis extending through their pivot bores;
positioning the variable geometry occipital fixation device in a location against an occiput;
rotating the first lateral member, the second lateral member, the midline member, or a combination thereof around the common axis; and
securing the variable geometry occipital fixation device to the occiput.

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.
