Abstract:

Objective　to measure and compare center edge angle (CEA) value between the Kazak and Han nationalities in Xinjiang region to provide reference for diagnosis of clinical hip diseases and design  design of the prosthesis.　Methods　Anteroposterior plain radiographs of adult pelvis from 114 patients with Han nationality and 93 patients with Kazak nationality were randomly selected, from which the value of the center edge angle was measured.　Results　The center edge angle t was （35.68±3.80）°on the left  and (35.94±3.74)° on the right in male with Kazak nationality, which corresponded to (33.76±3.93)° and  (33.77±3.93)° in male with Han nationality(P<0.05); The hip center edge angle was (33.45±4.34)° on the left and (33.41±4.64)° on the right in female with Kazak nationality, which corresponded to (31.41±3.57)° and  (31.42±3.57)°in female with Han nationality (P<0.05).　Conclusion　 The hip center edge angle of Xinjiang Kazak Male and female is larger than that of the Chinese male of Han and female.
