Fracture-Separation of the Distal Humeral Epiphysis in Children

소아 상완골 원위부 골단의 골절 및 분리

We have reviewed seven cases of fracture-separation of the distal humeral epiphysis, one of which was initially misdiagnosed as a fracture of the lateral condyle. There were difficulties in making the diagnosis. The injury must be distinguished from an elbow dislocation and a fracture of the lateral humeral condyle. All seven patients revealed posteromedial displacenemt of the distal humeral epiphysis on initial x-rays. Three patients were treated by closed reduction and cast immmobilization, and four patients by open reduction and internal fixation. All three patients with conservative treatment had slight cubitus varus(under 5 degrees). Two patients with operative treatment had significant deformities of the elbow, one 25 degrees of valgus and one 20 degrees of varus. In treatment of these injuries, accurate evaluation of the state of reduction is most important. We got acceptable results with a conservative treatment.

상완골 원위부 골단의 골절 및 분리 7례를 장기 추시하여 분석한 결과를 요약하면 다음과 같다. 세밀한 이학적 검사와 방사선 검사로 상완골 외과 골절이나 주관절 탈구와 감별진단이 필요하며, 정확한 진단에서 치료를 시도하는 것이 바람직할 것으로 사료된다. 치료는 골절의 정복 상태를 객관적이고 정확하게 평가할 수 있는 방법이 없어 어려우나 저자들의 경우 보존적인 치료로서 비교적 좋은 결과를 얻었다.
