A double nail guiding system for stabilizing broken bones includes a twin jig, first and second interlocking nails extending from the twin jig, wherein each interlocking nail defines a channel along a longitudinal axis thereof. The interlocking nails also include a distal portion which includes at least one hole. A centric or eccentric guiding pipe, including a channel in the center, extends through the first interlocking nail in a direction toward the second interlocking nail. A K-wire is inserted into the channel in the guiding pipe, such that the K-wire extends through the guiding pipe and through the hole defined in the second interlocking nail which is in the bone being stabilized. A guide probe is inserted into the channel in the second interlocking nail (which is in the bone) toward the distal portion thereof. In this manner, alignment of the hole in the distal portion of the first interlocking nail and the hole in the distal portion of the second interlocking nail is confirmed by contacting the guide probe with the K-wire. Advantageously, the first interlocking nail and the second interlocking nail are constructed to be of equal length and equal size. The procedures of distal locking screw targeting were simplified with an 100% successful rate. The radiation exposure to the patient and the surgeon's hand is no longer necessary during the distal locking of femur.
