Exceptional Combined Upper Limb Injury in an Adolescent: Radial Head Fracture, Both-Bone Forearm Fractures, Distal Ulnar Epiphyseal Separation and Scaphoid Fracture: A Case Report

Background: Combined injuries of the elbow, forearm, and wrist in adolescents are exceptionally rare and usually result from high-energy trauma. These complex patterns pose diagnostic and therapeutic challenges, particularly in patients with incomplete skeletal maturity. Case presentation: We report a rare case of a 17-year-old adolescent who sustained a complex left upper limb injury following a fall from height. Radiological assessment revealed a Mason type II radial head fracture, both-bone forearm fractures, a Salter–Harris type II distal ulnar epiphyseal separation, and a Schernberg type III scaphoid fracture. Surgical management included plate fixation of the forearm bones, screw fixation of the radial head and scaphoid, and temporary Kirschner wire stabilization of the distal ulna. Postoperative immobilization was followed by progressive rehabilitation, leading to satisfactory healing and functional recovery. Conclusion: This case emphasizes the importance of comprehensive assessment and early surgical management in complex upper limb injuries in adolescents to optimize functional outcomes.
