Time Reduction by Prebending Osteosynthesis Plates Using 3D-Printed Anatomical Models, In Patients Treated With Open Reduction and Internal Fixation.

Abstract

INTRODUCTION\nThe incidence of facial bones fractures is 18 to 32 for each 100,000 inhabitants. The most affected population are young working people. Fractures are most commonly caused by assaults and motor vehicle accidents. Its cost of care reaches 1.06 billion dollars. Premodeling osteosynthesis plates with anatomical models can decrease surgical time, bleeding, and increase patient satisfaction. This study aims to evaluate the impact of premodeled osteosynthesis plates, using anatomical models in patients with facial fractures.\n\n\nMATERIAL AND METHODS\nPatients with facial fractures treated by open reduction and internal fixation were included-Group A without premolding plates and Group B with premolding. The variables studied were: age, sex, etiology of the fractures, number of fractures, among other variables that reflect the quality of the results.\n\n\nRESULTS\nA total of 17 osteosynthesis plates were included in 6 patients. The age was 22 to 47\u200ayears; all patients were male. The maximum surgery time was 129 to 300 minutes. The average time to start work was 4.8\u200aweeks. When comparing the variables between the groups, we found no difference between the groups for bleeding P\u200a=\u200a0.24, the start of work P\u200a=\u200a0.19, the time of surgery P\u200a=\u200a0.082, or for osteosynthesis time P\u200a=\u200a0.15. There was only a significant difference in patient satisfaction, P\u200a=\u200a0.04.\n\n\nCONCLUSIONS\nThe evidence collected shows that premodeling the plates only improves patients satisfaction among facial fractures treated by open reduction and internal fixation.
