Penetrating injuries caused by sharp metallic objects is a common reason for emergency department visits [1-3]. The surgical extraction of foreign metallic bodies can often be complicated and time consuming procedure [1]. Although retained metallic foreign bodies in soft tissue or bone usually do not cause any harm, they might be removed when they cause pain, function loss and infection [2,4-5]. Despite the use of various preoperative detections: computed tomography, ultrasound and metal detectors, locating these metal objects can be extremely difficult, due to their small size, complex shape and the degree of penetration. A magnet could help to locate and extract the metal object more easily. Recent developments in magnet technologies have resulted in significant improvements in the flux density that is responsible for greater attraction forces and reductions in size. Because magnetic force obeys the inverse square law, a specially designed magnetic system should be used to guarantee adequate retraction of the metallic foreign body. Magnetic instruments are intended to help one achieve the best possible results in safe removal of reasonably located magnetic metal fragments.
