Compression plating (compression osteosynthesis) of mandible fractures

Compression osteosynthesis implies the use of rigid fixation across a fracture or osteotomy so that the fragments are compressed together even when the body part is at rest (no functional load). It must be applied in such a way that the addition of a functional load will not reverse the compressive force. So long as a positive (compressive) force is maintained at all times, no motion of the fragments relative to each other will occur, and healing will likely ensue. The principles and techniques for achieving dependable compression osteosynthesis across mandibular fractures are described, including the use of the dynamic compression plate, the eccentric dynamic compression plate, and lag screw compression fixation. Proper application, with indications and contraindications, is included, along with a discussion of the complications that may be encountered.
