Abstract:
1. An anchoring fastener for attaching an elastic cable to a substrate, suitable for use in stabilizing and fixating a bony fracture with an elastic cable having known diameter and elastic properties, comprising: a generally annular collar having a top, a bottom, and a first bore, said first bore having an upper, cylindrical portion above an inwardly tapering lower throat; a deformable ring capable of seating inside said annular collar; and an anchor post having an expanded head at an upper end, a cylindrical shoulder below said head, a lower, penetrating shaft, and a tapering transition between said cylindrical shoulder and said penetrating shaft; wherein said penetrating shaft is adapted to be passed through a second bore in said deformable ring and to penetrate into the substrate; and wherein said transition is dimensioned to compress said deformable ring seated in said collar when said anchor post is forcibly urged downward through said collar to penetrate into the substrate; and wherein, when said anchor post is seated with said head in abutting relationship with said top of said collar, an annular void of predetermined volume is defined between said shoulder of said post and said bore, said annular void having dimensions predetermined to compressively secure the elastic cable having known diameter and elastic properties.
