A new, image-intensifier mounted target device for closed interlocking nail
ing is described. The aim of locating the distal holes with the least radia
tion exposure is achieved. The proposed device has been designed to be moun
ted 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 pro
ved its reliability in the operating room during closed interlocking nailin
g procedures. (C) 2001 Elsevier Science Ltd. All rights reserved.
