Abstract:
Objective:To measure the pubo-femoral distance of hips of the infants diagnosed with Graf type Ⅰ by high frequency ultrasound.Methods:A total of 1 084 infants(2 168 hips) diagnosed with Graf type Ⅰ by ultrasonography were collected in Beijing Jishuitan Hospital from June 2019 to May 2020. The ultrasonographic examinations included Graf method and pubo-femoral distance measurement. The 95% medical reference value was adopted to confirm range of normal values of the pubo-femoral distance. And the differences of the pubo-femoral distance between different gender, age and bilateral hip were compared.Results:The pubo-femoral distance of hips diagnosed with Graf type Ⅰ was (0.27±0.06)cm, the pubo-femoral distance of males was(0.27±0.06)cm, the pubo-femoral distance of females was (0.27±0.07)cm. The 95% medical reference value was 0.15-0.38 cm. The 95% medical reference value of males was 0.15-0.39 cm, and the 95% medical reference value of females was 0.13-0.41 cm. There were no significant differences between the sexes or between the age(all P>0.05). The difference between the bilateral hip joints from the same infant was statistically significant[(0.274±0.064)cm vs (0.265±0.064)cm, P<0.05]. Conclusions:The 95% medical reference value of hip diagnosed with Graf type Ⅰ is 0.15-0.38 cm.
