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

Abstract

Introduction:The 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. Material and Methods: Patients 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. Results: A total of 17 osteosynthesis plates were included in 6 patients. The age was 22 to 47 years; all patients were male. The maximum surgery time was 129 to 300 minutes. The average time to start work was 4.8 weeks. When comparing the variables between the groups, we found no difference between the groups for bleeding P ¼ 0.24, the start of work P ¼ 0.19, the time of surgery P ¼ 0.082, or for osteosynthesis time P ¼ 0.15. There was only a significant difference in patient satisfaction, P ¼ 0.04. Conclusions:The evidence collected shows that premodeling the plates only improves patients' satisfaction among facial fractures treated by open reduction and internal fixation.

Custom Massive Allograft in a Case of Pelvic Bone Tumour: Simulation of Processing with Computerised Numerical Control vs. Robotic Machining

“…In orthopaedic surgery there has been a growing development of technologies for precision surgery, starting from planning software [ 23 , 24 , 25 , 26 , 27 ], passing through intraoperative navigation systems [ 27 , 28 ], and up to the recent applications of 3D printing, which involve models for planning [ 24 , 29 , 30 ], models for plates pre-bending [ 31 , 32 ], and the manufacture of custom prostheses [ 33 , 34 ]. The main purpose of these solutions is twofold: (i) to obtain better clinical outcomes with time savings in the operating room and a related cost reduction and (ii) to decrease the risk of postoperative infections [ 35 , 36 , 37 ].…”

3D printing for surgical planning in bone grafts for cleft-palate: a case report

“…We use the 3D model to pre-model the plates in fractures, proving that we reduce surgery time, trans-operative bleeding and patient satisfaction. 15,20 For these reasons we decided to use these advantages to carve the grafts and improve the contour and the contact surface.…”
