橈骨遠位端骨折に尺骨遠位骨端離開を合併したGaleazzi-equivalent lesionの1症例を経験した.症例は11才,男児.自転車走行中転倒し受傷した.X線像にて掌屈転位した橈骨遠位端若木骨折と尺骨遠位骨端離開を認め,尺骨骨幹端が背側に転位していた.尺骨は徒手整復を試みるも整復されず観血的整復を行った.骨片間に介在し整復を阻害していた骨膜を外した後も,整復が非常に困難で整復後も安定性が悪かったため,骨端離開ではあるが引き寄せ締結法にて固定した.術後7ヶ月の経過観察時では良好な経過をたどっているが,本外傷は骨端線損傷であり,今後の尺骨成長障害を長期観察する必要がある.

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.
