A Lateral Clavicle Physeal Fracture with Posteroinferior Medial Shaft Displacement Treated by Closed Reduction

Case: A 14-year-old boy sustained a distal clavicle physeal fracture after an e-bike crash. Examination showed swelling without threatened skin, restricted motion, and intact neurovascular status. Anteroposterior radiographs suggested a transphyseal fracture; however, axial imaging showed posteroinferior displacement of the medial metaphyseal fragment relative to the distal physeal-epiphyseal component. Closed reduction under general anesthesia, 4 weeks of sling immobilization, and early physiotherapy restored full, pain-free function by 10 weeks. Conclusion: Our report describes a successful outcome after closed reduction under general anesthesia without internal fixation for a distal clavicle physeal fracture with posteroinferior displacement of the medial metaphyseal fragment.
