A fracture reduction is mechanically achieved by supporting a body region having the bone fracture on a frame. A first reduction mechanism on the frame is operated to apply to the bone fracture a first predefined force reduction vector that returns the bone fracture to a corrective alignment in a first anatomic orientation, while also mechanically maintaining the corrective alignment in the first anatomic orientation. Independently, a second reduction mechanism on the frame is operated to apply a second predefined force reduction vector that returns the bone fracture to a corrective alignment in a second anatomic orientation different than the first anatomic orientation without altering the corrective alignment in the first anatomic orientation, while mechanically maintaining the corrective alignment in the second anatomic orientation. The fracture reduction is mechanically fixed by mechanically guiding the placement at least one bone fixing device into the reduced bone fracture.

This device can be used to create new bone to fill a gap in the mandible after surgical excision. It uses a bone reconstruction plate as a distraction device. The reconstruction plate fixes the bone stumps on both sides of the bone gap. In the middle segment of the plate overlying the bone gap, the transport bone disc is carried on a transport unit that moves along a rail on the outer surface of the reconstruction plate.

System, including methods and devices, for fixing bone. The system may include a bone plate having two or more plate members connected to one another with one or more movable joints. Each joint may permit the orientation of the plate members to be adjusted relative to one another in a single plane or two or more nonparallel planes. The joint may have a movable configuration and a fixed configuration. Methods of creating the bone plate are also provided.

A system for syndesmosis repair includes a flat band secured to bone by pulling a metal button through both the tibial and fibula bones, which button is then toggled into position to create tension, along the band, across the two bone segments to be fixated. Once the button is secure against the bone, flat suture tails against the lock at the initial insertion site serves to tension the band and bone segments in place. The system band offers syndesmosis repair with a knotless closure. The system is designed to provide this stabilized fixation for bone fractures, osteotomies, and arthrodesis, plus soft tissue to bone attachment, if desired. It is designed to apply a restorative fixation force across the tissue segments to stabilize them. The band's rigidity and compliant nature provides consistent and rigid fixation during the healing phase.

An implant for fixation of a bone includes a shaft having a proximal end and a distal end, and a longitudinal axis defined between the proximal end and the distal end. A plurality of blades are disposed on the shaft, and are helically twisted about the longitudinal axis. At least one of the blades has a variable blade width that increases in a direction along the longitudinal axis. A mechanism for coupling the implant to a second fracture fixation implant may be provided separately or in combination.

An apparatus and method for the repair of disruptions between bones. The apparatus defines a combination of sleeves, strands and crimps are provided to secure the bones, using a dual sided drill guide to prepare the bones for installation of the apparatus, which is adjusted upon installation to suit the appropriate alignment and tension of the apparatus.
