The purpose of this retrospective study was to investigate the
accuracy of such an assumption by using a radiologic comparison, which might be more objective. METHODS: One hundred consecutive adult patients (50
men and 50 women) aged 18-30 years with unilateral injury to the lower extremity
were studied. Full-length standing X-rays of these patients was used to analyze
the relationship between the pelvis and the uninjured lower extremity and compare
it between the sexes. The pelvic width was defined as the distance between the
centers of the bilateral femoral heads. RESULTS: The pelvic width did not differ
statistically between male and female (P=0.74). The femur length and sum of the
lengths of the femur and tibia differed between the sexes (both P<0.001).
Normalization of the pelvic width to the femur length or sum of the lengths of
the femur and tibia resulted in a significant difference between male and female
(P<0.001). The angle formed by the femoral and tibial mechanical axes correlated
strongly with the angle formed by the femoral anatomic and tibial mechanical axes
(Pearson correlation coefficient=0.89). DISCUSSION: Pelvic width does not differ
with respect to gender. The pelvis may appear relatively wider in women due to
the difference in body height. However, this difference may not increase Q-angle.
Patellar mal-tracking may stem from other, more critical predisposing factors.
