Lunate is classified morphologically into 2 types; type 1 which doesn't form joint with hamate and type 2 which articulates with hamate. The purpose of this study is to investigate the type of lunate of Korean by anteroposterior view of plain radiography of the wrists. Materials and Methods: The anteroposterior plain radiographs of 212 cases (106 males and 106 females) were reviewed and classified into type 1 and type 2. The age of the people was 15 to 74 (mean 40.7 years). Results: The number of type 1 lunate was 121 (57.1%) consisting of 58 males and 63 females. The number of type 2 were 91 (42.9%) consisting of 48 males and 43 females. There was no significant difference between genders (p=0.310). Conclusion: In one group of Korean population, 57.1% had type 1 lunate and 42.9% had type 2 lunate.
