Type III Monteggia Injury With Ipsilateral Distal Radius And Ulna Fracture

摘要

Introduction Monteggia described a lesion that consisted of a fracture of the proximal third of ulna and an anterior dislocation of the proximal end of the radius. Bado[1] in a series of forty patients, found that the fracture and dislocation could be displaced in various directions and described an extensive classification according to the direction of displacement of the radial head. This is a case report of an eight-year-old girl who sustained a type III Monteggia injury with ipsilateral distal radius and ulna fracture that to the best of our knowledge has not been previously reported in literature. Case Report An eight-year-old girl fell off a climbing frame from a height of about ten feet and sustained an injury to the right forearm. She had a severe dorsal angular deformity in the distal part of the forearm without any neurovascular deficit. The ipsilateral elbow was also swollen. Motion of the elbow and wrist was very painful and restricted. Radiographs showed dorsally displaced fractures of the distal radius and ulna along with a lateral dislocation of the radial head. In addition, there was a plastic deformation of the proximal ulna in a lateral direction (Fig 1).
