    摘要： A suture anchor comprises a shaft having a proximal and a distal end. A screw thread extends from the shaft and spirals from the proximal to the distal end. A cross-hole is formed through the shaft and the screw thread near the proximal end. The cross-hole receives a suture which provides a double end of suture to facilitate attachment of soft tissue. In a preferred embodiment, the shaft is tapered from a larger diameter proximally to a smaller diameter distally while the major diameter of the screw thread remains constant over most of its length. The suture anchor contains a driven portion which preferably contains a groove to conduct the suture from the cross-hole to the free end of the driven portion. A driver for the suture anchor having an engagement portion for engaging the driven portion likewise contains a groove so that when the engagement portion engages the driven portion the two grooves align to form an enclosed passageway for conducting the suture as the suture traverses the driven portion.

    摘要： The invention is directed to an apparatus for external fixation and stabilization of a fracture in a bone including a one-piece fixation rod, at least two fixation pins attachable to the bone, and at least two clamp assemblies. Each clamp assembly interconnects at least one fixation pin and the fixation rod, The fixation rod is compressible in an axial direction upon occurrence of axial loads typical to those experienced at the fracture, thereby allowing an axial compression loading to be placed on the bone at the fracture when the apparatus is in use. The fixation rod consists essentially of a non-homogeneous, i.e., composite, material.
