Abstract: A wire tensioner tip for use with a wire fixation bolt. First and second wires may be anchored to and tensioned across an external fixator frame with first and second wire tensioners. The first and second wires may be anchored at first anchor locations with first and second wire fixation bolts. First and second wire tensioner tips may engage with third and fourth wire fixation bolts, thereby preventing the third and fourth wire fixation bolts from rotating. The first and second wires may be tensioned to a desired tension with the first and second wire tensioners at the same time to prevent over-tensioning or under-tensioning. The first and second wires may be anchored at second anchor locations with third and fourth wire fixation bolts. By engaging the wire fixator bolts with the wire tensioning tips, fewer tools are required and one medical professional can tension two wires at once.

Abstract: An external fixation connection rod that allows for rapid and gradual length adjustment. In some embodiments, the fixation connection rod includes an inner sleeve received within a telescopic rod to allow for rapid adjustment of an overall length of the fixation connection rod. In some embodiments, the fixation connection rod includes an adjustment mechanism to allow for gradual adjustment of the overall length of the fixation connection rod by lengthening or shortening a threaded elongated member within the inner sleeve, and the adjustment mechanism includes a first rotation member, a second rotation member, and a spring. Distal translation of the first rotation member relative to the second rotation member allows the adjustment mechanism to move from a first, locked position to a second, unlocked position, allowing the first rotation member and the second rotation member to rotate about the inner sleeve and the threaded elongated member during gradual adjustment.

Abstract: A device and method is presented for enhancing the shape, mass, and strength of alveolar and intramembranous bone, primarily in areas of bony deficit. In one embodiment, the device is made up of a hollow body which forms a housing to contain a drive train and provide a surface for attaching mounting elements. A worm gear activating element which meshes with a threaded lead screw acts as the drive train. A carrier is coupled by threads to the lead screw. As the worm gear is turned, the lead screw rotates and causes the carrier to move along the axis of rotation of the lead screw. In this embodiment, the soft tissue in a region of tooth loss is reflected to expose the atrophic bone site. A piece of bone harvested from the exposed area or other bone attractant material is attached to the carrier. The soft tissue is adapted over the carrier and sutured, and the assembly is attached to available dental structures.
