    摘要: An external skeletal fixation device reduces load on the patient, is capable of freely moving and deformity correction of a bone and bone fragments, is simple in construction and can be attached to the patient by an operator who has not a very high skill and long experience. An external skeletal fixation device 1 includes a pair of pin clamp units 2 and 3 fixedly holding rodlike members 61 and 62 inserted, respectively, into a first part 9B2 and a second part 9B3 of a bone 9B on the opposite sides, respectively, of a virtual hinge point 9B1 in the bone 9B. The virtual hinge point corresponds to a center of rotational angulation of the bone, a center on which the first and the second part of the bone respectively on the 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 4 connecting the pair of pin clamp units 2 and 3 has a pair of arms 41 and 42 pivotally connected to the pair of pin clamp units 2 and 3, respectively. The pair of arms 41 and 42 are pivotally joined together. The respective axes A1, B1 and C1 of rotary joints A, B and C respectively connecting the pin clamp units 2 and the arm 41, the pin clamp unit 3 and the arm 42, and the arms 41 and 42 extend toward the virtual hinge point 9B1.
