Small and large titanium plates are equally effective for treating mandible fractures

Abstract

Purpose: The use of small titanium plates for the management of mandibular fractures continues to be a source of controversy because of their load-sharing properties. The purpose of the present study was to determine whether the use of small plates for mandibular fractures is as efficacious as large plates in a large level I trauma center.

Materials and methods: Consecutive subjects presenting with mandibular fractures were randomly allocated to the use of either small plates (group 1) or large plates (group 2). The primary predictor variable was the plate size. The primary outcome variable was fracture union. The secondary outcomes included complications and operative time. Statistical analysis was performed using the Wilcoxon rank sum test for ordinal and continuous variables and the χ(2) test or Fisher exact test for proportions.

Results: A total of 127 consecutive subjects with a fracture of the mandible were enrolled in the study. Of the 127 subjects, 53 completed the required follow-up of at least 6 weeks. There was no difference in the rate of fracture union between the 2 groups (P = .95).

Conclusions: The study findings suggest that the use of small plates and monocortical screws for mandibular fractures results in favorable outcomes compared with using larger plates and bicortical screws.
