Objective To evaluate the long-term clinical advantage results of Herbert screw in the treatment of capitellum fracture.Methods Eleven patients with displaced fractures of the humeral capitellum were treated by open reduction and internal fixation of the capitellar fragments with Herbert screws.Capitellum fracture patients were divided based on Bryan and Morrey classification： seven cases in typeⅠ,one case in type Ⅱ,three cases in type Ⅲ.Results Patient outcomes were evaluated using the Mayo elbow performance score.The follow-up period ranged from three to six years（mean 3.7 years）.All patients had a stable,pain-free elbow with good range of motion at follow-up.There was no evidence of avascular necrosis or degenerative change.Conclusion The Herbert screw can provi-de strong fixation and stability in the long-term follow-up.It is an ideal material in treating capitellum fracture.
