Abstract
A fixture for external bone fixation includes a number of pins clamped within pin mounting holes. Each pin extends through a flexible sleeve and through a clamping nut. Each pin mounting hole includes a pilot hole guiding the pin and an internally threaded portion engaging an externally threaded portion of the clamping nut. As the clamping nut is tightened, the flexible sleeve is longitudinally compressed, so that it expands transversely to clamp itself within the pin mounting hole and to clamp the pin within itself. A fixture configured particularly for external fixation of a fractured distal radius includes a number of such pins configured for attachment within a shaft portion of the radius and a number of such pins configured to attachment to a fragment of the fractured radius. The fixture also includes a sliding attachment block supporting a number of pins extending for lateral attachment to such a fragment.
