title: Collo-diaphysial angle of the femur in East African subjects.
abstract: The collo-diaphysial angle of East African subjects was investigated using 860 unilateral anteroposterior radiographs of the hip from 400 Ugandan and 460 Kenyan subjects, aged between 18 and 65 years using the standard techniques of Singh and Singh (1975). The angle ranged from 125-144 degrees with a mean of 133.3 degrees and a standard deviation (SD) of 5.3 degrees for Ugandan males; and 119-139 degrees, mean 123.4 degrees, SD 5.8 degrees for Ugandan females. The Kenyan values were 125-159 degrees, mean 140.2 degrees, SD 6.2 degrees for males; and 117-134 degrees, mean 125.7 degrees, SD 5.1 degrees for females, respectively. There were significant differences between males and females in both groups as well as between Ugandan and Kenyan males (P < 0.05). Using the demarking points method, only 19.0% of male Ugandans, 41.7% of male Kenyans, and 18.2% of female Kenyans could be identified by gender. This study documents for the first time the collo-diaphysial angle of East African subjects and has further confirmed that the angle is wider in men than women.
