Abstract
A compression transmission collar apparatus ( 20 ) for implantation into a bone ( 22 ) with a hole ( 28 ) having a hole wall ( 32 ) comprising an intramedullary nail ( 34 ) defining a bore ( 40 ) and a threaded fastener ( 42 ) and a compression transmission collar ( 58 ) including an exterior face ( 64 ) and a top edge ( 60 ) and a bottom edge ( 62 ) and a first end ( 70 ) intersecting the top edge ( 60 ) at an acute angle and the bottom edge ( 62 ) at an obtuse angle and a second end ( 72 ) intersecting the top edge ( 60 ) at an obtuse angle and the bottom edge ( 62 ) at an acute angle and the first end ( 70 ) partially overlapping and opposing the second end ( 72 ) to define a slit ( 74 ) such that applying a compressional load to the top edge ( 60 ) causes the first end ( 70 ) to slide relative to and along the second end ( 72 ) causing the compression transmission collar ( 58 ) to compress axially and expand radially pressing the exterior face ( 64 ) against the hole wall ( 32 ).
