Abstract
A graft fixation device and methods for using them. The device comprises a collar disposed about a central axis and having a threaded interior surface, an optionally threaded exterior surface, first and second annular drive elements disposed concentrically within the collar and externally threaded for engagement with the collar, and a graft securing element disposed concentrically between the drive elements. The collar and first drive element include driver elements at their respective, first ends for receiving a rotatable driver. The first drive element is rotatable relative to the collar for axial advancement toward the second drive element such that the graft securing element is sandwiched between the drive elements to form a unitary structure. The collar is rotatable relative to the unitary structure of the drive elements and graft securing element for moving the graft axially to apply a desired axial tension thereto. The unitary structure is also rotatable relative to the collar for applying a spiral twist to the graft.
