Purpose: The purpose of this study is to evaluate the treatment outcomes in patients with Sub-condylar fractures using 3D Strut Osteosynthesis Plates. Patients and methods: Six patients with sub-condylar fractures were selected randomly between the age of 26 to 36years.Treatment protocols included in the study were open reduction and internal fixation using 3D Strut Osteosynthesis Plates. Associated injuries such as Symphysis, Para symphysis, Zygomatic complex fractures were also included in this study. Statistical analysis using Friedman test and Wilcoxon signed-rank test were performed. Results: The results of our study revealed that there was a significant difference in the mouth opening of sub-condylar fracture patients (P-value ˂ 0.004). Comparison between preoperative, 2months and 6months follow-up for additional fractures, Occlusion, Complications of Sub-condylar fractures were also performed. Preoperative and 2months follow-up showed significance with P-value ˂ 0.02. Preoperative and 6months follow-up also showed significant P-value ˂ 0.028 and 2months to 6months follow-up revealed significant P-value ˂ 0.059. Postoperative radiographic evaluation showed that the osteosynthesis is relatively stable. Conclusion: All the patients treated with the Strut plating system was functionally stable, well rehabilitated and also proved significant statistical analysis. In our study with sample size limitations, the fracture reduction of sub condyle with the new three- dimensional Strut plate showed excellent stability with no displacement and neutralization of the changing strains in the condylar region. Therefore, further studies with a larger sample size can help to re-evaluate the results in further research using the 3D strut Osteosynthesis plating system.
