Summary: This case series describes the successful reconstruction of mandibular contour in dogs after the excision of mandibular acanthomatous ameloblastoma. The use of a regenerative approach, involving a titanium locking plate and rhBMP-2-infused compression resistant matrix, resulted in tumor-free surgical margins and restoration of normal jaw kinematics. All dogs returned to a normal lifestyle and exhibited normal occlusion.

Summary: This study used the induced membrane two-stage technique to treat infected ankle bone defects. A retrograde intramedullary nail was used to fuse the ankle in the second stage, and the clinical effect was observed. The results showed that the induced membrane technique combined with a retrograde intramedullary nail is an effective treatment method for infected bone defects of the ankle.

Summary: A new base-fixation system for mandibular defect reconstruction was designed and evaluated through finite element analysis and fatigue simulation analysis. The results demonstrated that the new system had superior fixation ability and good fatigue performance, making it suitable for clinical mandibular defect reconstruction.

Summary: This study investigates bone remodelling responses to mandibulectomy by developing an algorithm that incorporates patient-specific longitudinal data. The study aims to simulate bone remodelling activity in the conjunction region with a fibula free flap reconstruction and compare the long-term outcomes of different fixation plate designs. The results show a decrease in overall bone density over time, except in the docking site where bone apposition occurs after a decrease in bone density. Different screw positioning does not significantly influence bone remodelling outcomes.

Summary: This study compared the 2-year clinical and radiological outcomes of arthroscopic-assisted bidirectional stabilization procedures using a single low-profile or double-suture button technique for patients with acute high-grade AC joint dislocation. The results showed that both techniques had comparable outcomes, with the LPSB technique showing higher patient satisfaction and no postoperative revision events.

Summary: This study compared the biomechanical behavior of human and macaque mandibles pre- and post-fracture and fixation using finite-element models. The results showed small differences in deformation and strain between human and macaque mandibles. More rigid biplanar fixation in the human model approximated healthy bone strains and moments better and resulted in less interfragmentary strain compared to less rigid Champy fixation. Contralateral chewing exacerbated deviations in strain, moments, and interfragmentary strain, especially under Champy fixation. These findings confirm that macaques are excellent animal models for studying mandibular fixation and support the use of rigid biplanar fixation in the treatment of isolated mandibular angle fractures.

Summary: The application of Distraction Osteogenesis (DO) techniques in reconstruction surgeries is advantageous with fewer side effects. However, the development of automatic devices for controlled continuous force still requires further research. A two-axis continuous distractor is proposed for mandibular reconstruction, meeting the current requirements.

Summary: This study compared the complication rates of mini-plate (MP) and reconstruction bar (RB) osseous fixation in fibula flap mandibular reconstruction, finding that MP fixation is associated with higher rates of plate-related complications.

Summary: By substituting iron ions into one-dimensional clay mineral palygorskite, a narrow band gap iron-substituted nanocomposite was formed, exhibiting remarkable photocatalytic nitrogen fixation capability under visible light. Additional Fe2O3 precipitation on the surface forms dendritic heterostructure, enhancing light absorption and exposing more active sites.

Summary: This study aimed to fabricate 3D-printing titanium grid scaffolds to achieve bone fusion in mandibular segmental defects. The results showed that the scaffolds with sufficient pores and basic biomechanical strength could facilitate bone regeneration and integration of bone broken ends. Clinical observations on both animal models and patients confirmed the successful bone regeneration in mandibular defects using the titanium grid scaffolds.

Summary: This study evaluated the real-world outcomes of surgical stabilization of rib fractures (SSRF) at Westmead Hospital, Australia, and found early outcomes to be similar to best-evidence in the literature. SSRF within 3 days of hospital presentation was associated with significantly reduced ICU length of stay. Continuous evaluation of real-world data is necessary for quality assurance and to ensure outcomes remain consistent with benchmarks from best-evidence.

Summary: Ventral hernias can be caused by various reasons, leading to decreased quality of life for patients. Modern techniques and materials for abdominal wall reconstruction, particularly the use of mesh, have advanced significantly. Surgeons must carefully consider different factors when deciding on mesh fixation methods for effective repair.

Summary: This study compared the accuracy of mandibular reconstruction and clinical outcomes between conventional reconstruction plates (CR) and patient-specific implants (PSI). The results showed no significant differences in reconstruction accuracy and postoperative complications between the two methods, but there were some discrepancies at specific measurement points.

Summary: This study evaluated the reliability of using a trapezium plate and endoscope in the open reduction and internal fixation surgery for mandibular subcondylar fractures. The results showed that patients recovered normal mandibular movement within 6 months postoperatively, and radiographic controls confirmed good anatomical reduction.

Summary: Our study aimed to estimate the prevalence and factors affecting surgical site infections (SSI) following open reduction and internal fixation (ORIF) for mandibular fractures. A systematic literature search was conducted, and data from 75 eligible studies were analyzed. The overall prevalence of SSI was estimated to be 4.2%, with significant heterogeneity between studies. The prevalence varied across geographic regions, with higher rates in America than in Europe and Asia. Further research is needed to fully understand the etiology of these infections.
