Traumatic Irreducible Pediatric Radial Head Dislocations: A Unique Case and Review of the Literature.
Case Report
Irreducible radial head dislocations are uncommon injuries and blocks to reduction typically result from interposed soft tissue. We report the case of a pediatric patient who sustained an irreducible radial head dislocation with a concomitant posterior elbow dislocation and coronoid process fracture. To the author’s knowledge, irreducible radial head dislocations presenting as part of a terrible triad like constellation of injuries have not been previously reported. A case-based review of the literature was also performed./r/nA 7-year-old male presents to our pediatric hospital as a transfer from an outside hospital after sustaining a posterolateral radial head and posterior elbow dislocation secondary to a fall. CT imaging and 3D reconstruction revealed a Type 1 coronoid process fracture. At our institution, closed attempts at reduction in the operating room under fluoroscopy with general anesthesia were also unsuccessful. Open reduction of the radial head and repair of the soft tissue structures was ultimately required to stabilize the patient’s elbow injury./r/nIrreducible pediatric radial head dislocations are rare and inherently unstable injuries. To the authors’ knowledge, there are no prior reports of irreducible radial head dislocations that present in a terrible triad like fashion with a coronoid process fracture and posterior elbow dislocation. In the present report, successful treatment of this injury required open reduction and soft tissue repair. .
