This study defined the characteristics of Baumann�s angle in a local population. One hundred and sixty-eight radiographs were studied and categorised into age groups at two-year intervals. Two observers measured all the angles and the data was analysed by computer using various statistical methods. The mean value was 70.1? in boys and 69.9? in girls; no statistically significant difference could be demonstrated in the different sex or age groups. However, some differences to Western studies were noted. This could be important information for the management of supracondylar fractures of the elbow in children.
