1. An occipital fixation method, comprising:
- positioning a second lateral member of a variable geometry occipital fixation device in a location against an occiput, wherein said second lateral member comprises a proximal end, a distal end, a pivot bore located at said proximal end, and an attachment bore located at said distal end;
positioning a first lateral member of said variable geometry occipital fixation device against said occiput and overlying said second lateral member, wherein said first lateral member comprises a proximal end, a distal end, a pivot bore located at said proximal end, and an attachment bore located at said distal end;
positioning a midline member of said variable geometry occipital fixation device against said occiput and overlying said first lateral member, wherein said midline member comprises a proximal end, a distal end, a pivot bore located at said proximal end, and a fixation bore located at said distal end;
aligning said pivot bore of said midline member, said pivot bore of said first lateral member, and said pivot bore of said second lateral member along a common axis extending therethrough;
rotating said first lateral member, said second lateral member, or both around said common axis; and
securing said variable geometry occipital fixation device to said occiput.
