A bone distraction device and a method for installing and using the bone
distraction device are disclosed. Separated portions of a bone may be
coupled to two or more mounts of the bone distraction device. Each
portion of the bone may be coupled to at least one mount. The mounts may
be contoured in arcs of at least .pi./3 radians to accommodate the
circumference of the bone. The bone distraction device may include three
or more guide rods coupled to the mounts. A distractor may be used to
move one mount relative to one or more other mounts to distract the bone
portions. In one embodiment, one mount may be coupled to a transport
segment of bone for transport distraction between two bone segments. In
some embodiments, a hydraulic bone distractor may be used to distract the
bone portions.
