Purpose: To evaluate the clinical results of cortical (lag) screws in internal fixation of mental fractures.
Methods: 12 patients with single linear mental fracture underwent internal fixation using cortical screws. The patients were followed up for 6 to 9 months after fixation.
Results: Of 12 cases, 1 cortical screw was used in 10 cases, and 2 cortical screws were used in 2 cases. The wound healed primarily postoperatively. The patients had normal occlusion and mouth opening.
Conclusion: Fixation of mental fracture using cortical screw can achieve good stability and appropriate compression. The technique is simple and easily performed, which avoids the bending of the reconstruction plate to adapt to the complex configuration of the mandible, reduce the surgical time, and promote the healing process by producing stress in the fracture lines.

Background: This study investigated the association between photoreceptor structural restoration and visual function outcomes in patients undergoing surgery for closed macular holes (MHs). Using adaptive optics scanning laser ophthalmoscopy (AOSLO) and microperimetry, we aimed to provide a more detailed understanding of photoreceptor recovery and visual improvement in closed MHs.
Methods: We conducted a retrospective observational study of 31 eyes of 28 patients who underwent vitrectomy with internal limiting membrane (ILM) peeling to treat idiopathic MHs.

Purpose: Olecranon osteotomy has been associated with loss of reduction, nonunion, implant failure, and migration of wires. We aim to evaluate quality of reduction of the osteotomy site as a predictor of olecranon osteotomy nonunion.

Background: Proximal humerus fractures (PHF) are common with approximately 30% requiring surgical intervention. This ranges from open reduction internal fixation (ORIF) to shoulder arthroplasty (including hemiarthroplasty, total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA)). The aim of this study was to assess trends in operative interventions for PHF in an Australian population.

Background: Hemodynamically unstable pelvic ring fractures from high-energy trauma are critical injuries in trauma care, requiring urgent intervention and precise diagnostics. With ongoing advancements in trauma management, treatment strategies have evolved, with some techniques becoming obsolete as new ones emerge. This study aimed to evaluate changes and trends in treatment algorithms for these injuries over approximately 40 years.
