Abstract
An external skeletal fixation device includes first and second pin clamp units fixedly holding rodlike members inserted, respectively, into a first part and a second part of a bone on the opposite sides, respectively, of a virtual hinge point corresponding to a center of rotational angulation, a center on opposite sides of a fracture site of the bone or a part of the osteotomy site for deformity correction are turned, or a center about which a joint turns. A connecting mechanism connecting the first and second pin clamp units has first and second arms pivotally connected to the first and second pin clamp units, respectively. The respective axes of rotary joints respectively connecting the first pin clamp unit and the first arm, the second pin clamp unit and the second arm, and the first arm and the second arms extend toward the virtual hinge point.
