Importance of Magnetic Resonance Imaging Examination in Unossified Avulsion Fracture of Child Elbow

  • 1Department of Orthopedic Surgery, College of Medicine, Konyang University, Daejeon, Korea.


Unossified elbow avulsion fractures of children should be treated with care. Simple avulsion fractures seen on an x-ray may actually be severe injuries such as elbow joint subluxation or radial head dislocation. So, definite diagnosis is important in determining appropriate treatment of avulsion fractures around the unossified elbow, and magnetic resonance imaging (MRI) examination plays a key role in the diagnosis. We experienced avulsion fracture of the capitulum with common extensor tendon and lateral collateral ligament injuries and ulnar coronoid process fracture in an 11-year-old boy and radial head dislocation with common flexor tendon and partial ulnar collateral ligament injuries in an 8-year-old boy. We would like to talk about the importance of MRI in unossified avulsion fracture of child elbow by reviewing 2 case reports.
