title: The femoral collodiaphyseal angle in Malawian adults.
abstract: We used unilateral anteroposterior radiographs to measure the collodiaphyseal angle of the hip in 368 Malawian adults--222 men and 146 women 18 to 76 years old. The angle ranged from 105 degrees to 144 degrees (mean, 121.09 degrees; SD, 7.17 degrees). Results confirmed that the angle was wider in men than in women-indicating dimorphism based on sex--but no Malawian could be identified by sex using the recommended demarking point method of Jit and Singh (1966). The importance of the angle and its usefulness to practicing orthopedic surgeons in this part of the world are emphasized.
