ABSTRACT:
An external fixator for a fractured distal radius including a first plurality of vertical passages for pins extending downward from a first pin mounting block into one or more bone fragments and one or more frame element apertures extending from an elongated frame element for pins extending downward from the device into the shaft of the radius. In addition, the elongated frame element includes a sliding pin slot with a sliding structure allowing a single pin to be moved to provide extension between the fragments and the shaft. A sliding internal plate including holes aligned with the first plurality of vertical passages is moved by a pair of setscrews to clamp the pins extending through the first plurality of vertical passages. The device also includes a second pin mounting block that extends downward parallel to the pins extending from first pin mounting block to hold pins directed laterally into the fragment(s).
