RESUMEN
Fracture dislocation of the proximal humeral epiphysis in children is rare and constitutes only 3% of all epiphyseal injuries. In dealing with such fractures, there is still much controversy in treatment modalities. In this study we try to evaluate the results of treatment of proximal humeral epiphyseal fracture dislocation with open reduction and internal fixation. From 2001 to 2004, fourteen children between the age of 4 to 15 years with unstable or irreducible types of fracture dislocation of the proximal humeral epiphysis were treated with minimal exposure, open reduction and internal fixation using Rush rods or K. wires. There were 11 boys and 3 girls. The mean follow-up was 22.7 months [12 - 36]. The union rate was 100% and the average duration of union was 5.9 weeks. According to Neer's scoring system, 13 children [92.9%] had excellent results, and one child [7.1%] had satisfactory results. Occasional pain was a complaint occurs in 2 children [14.3%] and superficial wound infection was detected only in one child [7.1%]. We think that open reduction through minimal exposure and fixation with Rush rods or K. wires is an effective way to manage these unstable or irreducible fractures of the proximal humeral epiphysis as it allows more rapid rehabilitation of the shoulder motion and function
