Today's trauma edition covers six open-access studies spanning pediatric elbow reconstruction, congenital radial head dislocation treatment, femoral neck fixation systems, tibial nailing techniques, clavicle fracture outcomes, and infection prediction in HIV patients. Key findings include superior outcomes with staged reconstruction for neglected lateral condylar fractures, effective rotational osteotomy for congenital radial head dislocation, faster healing with femoral neck systems versus cannulated screws, potential advantages of isolated tibial nailing over combined tibia-fibula fixation, excellent results with operative clavicular fracture management, and promising infection prediction using systemic immune-inflammation index in HIV patients.
