A new distal targeting device for closed interlocking nailing.

A new, image-intensifier mounted target device for closed interlocking nailing is described. The aim of locating the distal holes with the least radiation exposure is achieved. The proposed device has been designed to be mounted on the image-intensifier, is absolutely stable, eliminates the need for a specialised X-ray technician and allows the surgeon to be away from the radiation beam (direct or scattered). It also permits image intensification in the anteroposterior view, without losing the target. The device has proved its reliability in the operating room during closed interlocking nailing procedures.
