A simple technique for the placement of Schanz screws into bone using minimal radiologic control

The insertion of Schanz screws into the bone during external-fixation procedures in trauma and elective orthopaedic surgery is usually done under roentgenologic control. In order to minimize irradiation exposure for the patients, as well as surgeons, we describe a simple method of Schanz screw placement.The roentgenologic control of the position of the half-pins is only necessary at the beginning and the end of the procedure.This technique is simple, shortens the operating time and reduces the amount of radiation exposure to both the patient and surgeon. It is a valuable technique in many resource-poor environments who do not have the facilities for an image intensifier fluoroscopy or C-arm as well as in austere situations such as during military operations.
