A Case of Galeazzi-equivalent Lesion

Abstract

We report a case of Galeazzi-equivalent lesion. This injury is characterized by complete distal ulnar epiphyseal separation instead of dislocation of the distal radio-ulnar joint. A 11-year-old boy was injured by falling from a moving bicycle. X-ray showed greenstick fracture of the distal radius with volar angulation, and Salter-Harris type II fracture of the distal ulna with dorsal displacement of the proximal metaphyseal fragment. Closed reduction under general anesthesia was unsuccessfully attempted. Open reduction and internal fixation were performed. Torn periosteum was interposed at the fracture site, blocking reduction. In spite of removal of the periosteum, reduction was difficult, and after obtaining reposition, the instability of the fracture site in pronation of the forearm remained. We fixed with tension band wiring with full knowledge that it was epiphyseal injury. Neither growth arrest nor loss of range of motion occurred at seven months after operation. We will continue follow-up to prevent growth disturbance of the distal ulnar physis.
