Cortical lag screw fixation for the management of mandibular injuries, experience tips

“

Our clinical experience indicates that CLSFT is the most cost-effective and rapid technique for fixation of mandibular fractures, producing good treatment results with very limited complications. However, this technique is sensitive and requires surgical expertise. It may be applied to most mandibular fractures with specialized characteristics, as follows: • Fresh sagittal split (true symphyseal) fractures. • Single straight line, parasymphysis fractures directed anteriorly at the inferior border were more accessible. Fracture segments that were posteriorly directed and comminuted or cracked were not favorable. • Long chins with curved or curled anterior regions are ideal for the application of two lag screws. • Standardized indications of oblique transverse surface fractures in the anterior, body, and angle regions. • CLSFT is not indicated in comminuted fractures, old, or delayed fractures, or in missing segment or gap fractures (in cases where compression is contraindicated).
