Effective reduction of mandibular angle fracture with mini-implant; case report

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

Strength of Surgical Wire by Different Wiring Technique / 대한정형외과학회잡지

The role of surgical wire in the bone and joint surgery is very important. To get a maximum effect of the surgical wiring, the orthopaedic surgeon should not only select appropriate wire diameter but also apply adequate wiring technique. When strong fixation is required, wire loops are frequently untrustworthy. These are due to insufficient caliber or inadequate technique of wire thightening and/or twisting. The theoretical background for effective wiring technique and useful diameter in cerclage wiring is poor. Ultimate stress and stress at breaking point of different diameter of the wire was higher in 16G than 18G or 21G. Twist knot was stronger than knot twist. Wire holder was more effect than tensioner(york). Tension tightening with twist knot by wire holder have been found most suitable for internal fixation by surgical wire.
