A post for attaching to an alignment wire whereby said post comprises: a cylindrical body having first end and an opposing second end, said body having a center axis and a radius; a bore coaxially disposed through said body from said first end to said second end; a pair of generally L-shaped locking elements attached to said second end, each of said locking elements comprising: a flange arm attached to and extending perpendicularly from said second end, said flange arm having a generally arcuate exterior surface coaxial and co-radial with said body, and an opposing planar interior surface; and a flange attached to and extending perpendicularly from said flange arm, said flange having an arcuate exterior surface coaxial and co-radial with said body, said arcuate exterior surface having opposing ends connected by a planar surface 109), and said flange having a planar surface distal said second end and an opposing surface proximal said second end; wherein each of said flange arms is attached to said second end at opposing sides of said center axis; wherein said planar surfaces 109) are in an opposing parallel configuration defining a center channel extending from said distal surfaces to said proximal surfaces of said flanges, said center channel perpendicular to and passing through said center axis; and wherein a gap between said second end of said body and each of said flange proximal surfaces defines a pair of opposing locking recesses having a first end in communication with said center channel and an opposing second end adjacent said interior surface of said each flange arm; wherein, when an alignment wire is passed through said center channel, said alignment wire is disposed at said second end such that rotating said body causes said flanges to capture said alignment wire in said locking recesses. a cylindrical body having first end and an opposing second end, said body having a center axis and a radius; a bore coaxially disposed through said body from said first end to said second end; a pair of generally L-shaped locking elements attached to said second end, each of said locking elements comprising: a flange arm attached to and extending perpendicularly from said second end, said flange arm having a generally arcuate exterior surface coaxial and co-radial with said body, and an opposing planar interior surface; and a flange attached to and extending perpendicularly from said flange arm, said flange having an arcuate exterior surface coaxial and co-radial with said body, said arcuate exterior surface having opposing ends connected by a planar surface 109), and said flange having a planar surface distal said second end and an opposing surface proximal said second end; wherein each of said flange arms is attached to said second end at opposing sides of said center axis; wherein said planar surfaces 109) are in an opposing parallel configuration defining a center channel extending from said distal surfaces to said proximal surfaces of said flanges, said center channel perpendicular to and passing through said center axis; and wherein a gap between said second end of said body and each of said flange proximal surfaces defines a pair of opposing locking recesses having a first end in communication with said center channel and an opposing second end adjacent said interior surface of said each flange arm; a flange arm attached to and extending perpendicularly from said second end, said flange arm having a generally arcuate exterior surface coaxial and co-radial with said body, and an opposing planar interior surface; and a flange attached to and extending perpendicularly from said flange arm, said flange having an arcuate exterior surface coaxial and co-radial with said body, said arcuate exterior surface having opposing ends connected by a planar surface 109), and said flange having a planar surface distal said second end and an opposing surface proximal said second end; wherein each of said flange arms is attached to said second end at opposing sides of said center axis; wherein said planar surfaces 109) are in an opposing parallel configuration defining a center channel extending from said distal surfaces to said proximal surfaces of said flanges, said center channel perpendicular to and passing through said center axis; and wherein a gap between said second end of said body and each of said flange proximal surfaces defines a pair of opposing locking recesses having a first end in communication with said center channel and an opposing second end adjacent said interior surface of said each flange arm; wherein, when an alignment wire is passed through said center channel, said alignment wire is disposed at said second end such that rotating said body causes said flanges to capture said alignment wire in said locking recesses.
