Abstract
A fixator for adjustably securing a first skeletal element on a superior side of an ankle joint relative to a skeletal element on the inferior side of the ankle joint. The fixator includes a bone screw clamping assembly that preferably secures a pair of screws to the bones of the foot. The bone screw clamping assembly is attached to a central body of the fixator and is operative for articulating the pair of bone screws about an axis substantially co-axial with the anatomical pivot axis of the ankle joint. The bone screw clamping assembly further defines a radiographic window for permitting lateral radiographic examination of the anatomical pivot axis of the ankle joint.
