System and Methods For Hip Fracture Fixation with Bolt Synchronization

A method of using a fracture fixation system, comprising:

• drilling into a bone a first superior bore having a first diameter to a first depth;
• drilling into the bone a first inferior bore having a second diameter to a second depth;
• installing an implant to the bone;
• inserting a bolt into a transverse bore defined through the implant such that a distal end of the bolt extends into one of the first superior bore and the first inferior bore;
• and
• inserting a lag screw into the transverse bore defined through the implant such that a distal end of the lag screw extends into the other one of the first superior bore and the first inferior bore,
• wherein inserting the lag screw includes rotating the lag screw to advance the lag screw distally relative to the bolt such that a thread of the lag screw engages with a transition portion of a negative thread of the bolt to align the thread of the lag screw with the negative thread of the bolt.
