1. EUROPEAN PATENT 0686373 BY ANIRUDDHA NAZRE

‎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

The present invention relates to a nail and fastener assembly for use in providing a stable construct for optimal fixation of the hindfoot and to methods for implanting the nail and fastener assembly. One embodiment of the nail and fastener assembly provides additional fixation, for example, in the form of one or more threaded bores, to hold the fasteners in a fixed position. Another embodiment provides angled bores to allow multi-planar and multi-axial implantation of the fasteners. In some instances, the fasteners may cross one or more articulating surfaces of the foot. For example, the fastener may traverse one or more of the calcaneo-cuboid and the talo-calcaneal articulating surfaces to aid in more secure stabilization of the hindfoot

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.

This invention provides for the angular and lateral adjustment of a pair of fixator rods in an infinite number of planes.

This invention provides for the angular and lateral adjustment of a pair of fixator rods in an infinite number of planes. The angular adjustment member may be rotated about a center axis of the connector such that the connected fixator rods may be angled relative to one another in any plane called for. Similarly, the lateral adjustment may be rotated about the center axis of the connector such that the two fixator rods may be shifted laterally relative to one another in any direction. The adjustable connector provides for the adjustment of the fixator rods after the rods have been connected to the bone pins. Therefore, after a surgeon has reduced and stabilized the fracture, minor adjustments can be carried out to fully align the bone fragments without disconnecting the fixator rods or the bone pins. After all adjustments have been made, a series of locking bolts or pins can be engaged to hold the adjustable connector in a fixed position.
