Fixin internal fixator: Concept and technique

Summary

This report describes the Fixin internal fixator system[a], a fracture fixation device characterised by a locking conical coupling between screw heads and titanium alloy inserts that are screwed into a stainless steel plate construct. The mechanical principles, implants, instruments and surgical technique are discussed.
