EFECE Systems are a new innovative way of fracture fixation and compose of 3 components: EFECE wire retainer, EFECE wire and EFECE hand set. EFECE Wire Retainer: Cylinder shaped and has a hole for insertion of EFECE wire. It consists of 2 parts that catch each other by threads. Upper part functions as a cap. Lower part has 3 cone shaped grooves for insertion of 3 balls. Locking mechanism is with the help of the balls in the cone shaped grooves. During forward movement on EFECE wire, balls move to the base of the cone which is wider and release the EFECE wire. Though, during backward movement, balls jam at the narrow part of cone shaped grooves and lock the EFECE wire. EFECE Wire: A kind of Kirschner wire which is produced with suitable hardness for EFECE wire retainer. EFECE Hand Set: Includes sleeve, working canul, outer catcher, screw driver, compressor, wire cutter, magnet, latch and ball removers. All hand set designed for percutaneous technique.
