Abstract
An orthopedic bone bridge, suitable for internally fixating and stabilizing fractured bones. The bone bridge includes: first and second bone plates for attachment to bone fragments by bone screws or the like on opposite sides of a bone fracture, a pair elongate parallel hollow legs on which the plates are mounted and the second plate is slidably engaged and is moveable with respect to the first plate, and an elastic cable or microcable attached to the first plate and extending down through the legs and around said second plate. The elastic cable is configured to provide a controlled tensile force between the plates when they are pulled into a longitudinally spaced apart position with the bone bridge then applying a correspondingly compressive force onto the bone fracture when the plates are secured to bone fragments on opposite sides of a bone fracture.
