Its pitfalls include increased operative time, increased radiation exposure, and the incidence of distal locking screw misplacement. To solve this problem, a new ideal targeting system should not only be convenient to surgeons to effectively shorten operative duration and lower the chance of screw misplacement, but be cost-effective. Many targeting systems and techniques have been developed as follows: drill guide extensions, computer-aided navigation systems, transillumination methods, distal targeting guidelines, various other free-hand techniques, and even "nail-over" procedures by using two intramedullary nails. However, most of them are expensive, bulky, and may have a steep learning curve for the surgeons. To find positioning in vitro can be solved through-hole problems, and reduce the light scattering method using an optical level, and look forward to for a variety of different brands of bone nail / bone plate. We hoped that this targeting device will decrease operative time, decrease the misplacement rate, and decrease the radiation from fluoroscopy.
