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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
