Targeting device for intramedullary nails: A new high-stable mechanical guide

Next generation distal locking for intramedullary nails using an electromagnetic X-ray-radiation-free real-time navigation system

“…2,13 The placement of three holes in close proximity generates an area of stress concentration; cortical defects after redrilling procedures because of misguidance lead to bone weakening or inadequate fixation. 3,14 Involuntary movements that occur during the change from locating the holes to aiming the drill or by applying pressure during the drilling process can bias successful distal locking.…”

Is a Magnetic-Manual Targeting Device an Appealing Alternative for Distal Locking of Tibial Intramedullary Nails?

“…The Sanatmetal® targeting system is quite simple and easy to learn; our cadaver study revealed a mean duration of 9.6 minutes at the most for the setting of four distal screws. Of interest, the mean targeting time (time between the beginning of alignment of the distal holes and setting of the two distal screws) of a mechanical system needing fluoroscopy that was applied in a clinical trial was evaluated to be 24 (20 to 30) minutes (20); nevertheless, taking into account all of the differences between our cadaver and this clinical study, we could show that the Sanatmetal® device is able to assist surgeons in rapid drilling of holes for distal locking screws. The system is sufficiently robust and profoundly precise; only one failure occurred due to a surgical error of a student.…”

Fluoroscopic freehand and electromagnetic-guided targeting system for distal locking screws of humeral intramedullary nail

“…The Sureshot TM Distal Targeting System (Smith & Nephew, Inc., Memphis, TN, USA) is a new centring system for the distal locking of intramedullary nails, which uses computer technology based on electromagnetic fields. The advantages of this feature are: the reduced exposure to ionizing radiation for both patient and surgeon [22][23][24][25][26][27], the reduced potential of placement errors of the distal screws and the reduced surgical time [28][29][30][31].…”
