“…The results were in accordance with the results of Raux et al. (), which demonstrated a strong correlation between PT and SFP in a European population. The close relationship between SFP angle and PT could be explained by simple analysis of the relative location of anatomical landmarks during sagittal pelvic rotation (Hongda et al.…”

“…Having enrolled a cohort of 170 healthy adolescents, the current study yielded a physiological norm for PT with an average value of 4.33°. Raux et al (2014) reported that PT averaged 6.67°in European pediatric population and the difference between the two studies may be due to ethnic difference. In the current study, the average PT in females Fig.…”

“…According to Raux et al. () PT increased gradually after 6 years of age, but was larger at the age of 5 or younger than the age of 6–10 years. In accordance with previous studies, a strong correlation between PT and age was found in the present study ( P < 0.001), and a significant increase of PT was found to start from 14 years in females and 16 years in males, which may be attributed to the 2‐year maturational difference between boys and girls of similar chronological age.…”

“…Raux et al. () reported that PT averaged 6.67° in European pediatric population and the difference between the two studies may be due to ethnic difference. In the current study, the average PT in females aged over 14 years old and males aged over 16 years old was 8.64° and 7.44°, respectively, which is comparable to the results of previous studies (Mac‐Thiong et al.…”

The objectives of the present study are to evaluate the correlation between pelvic tilt (PT) and the sacro-femoral-pubic (SFP) angle in Asian healthy adolescents, to provide the normal value of SFP angle as reference data in Asian adolescents, and to clarify whether the predictability of PT could be affected by gender and ontogenesis. In all, 100 girls with a mean age of 12.66 years (range 8-18 years) and 70 boys with a mean age of 13.35 years (range 8-18 years) were recruited in this retrospective study. SFP angles and PT were obtained on long-cassette standing upright radiographs. The subjects were grouped based on age. Independent-sample t-tests were performed to compare age, SFP angle, and PT between genders. In all age groups, the relationship between SFP angle and PT was analyzed by Pearson's correlation analysis and linear regression analysis, respectively. Reliability analysis showed high intra-and inter-observer agreements in PT and SFP, with an intra-class correlation coefficient (ICC) > 0.8. SFP angle averaged 71.64°AE 4.91 in all the normal subjects, of which the mean PT was 72.03°AE 4.94 in the female group and 71.09°AE 4.83 in the male group. SFP and PT were strongly correlated in all the age groups according to Pearson's correlation analysis. The overall coefficient was 0.679 in girls and 0.584 in boys. The present study is the first to describe the normal value of SFP angle in healthy Asian adolescents to serve as a reference data. In all age groups, SFP angles can be used to predict PT when lateral radiographs do not permit assessment of PT. The predictability of SFP angle for PT was not affected by gender or maturation status.

“…In females and males, the vertical distance between the upper edge of the pubic symphysis and the midpoint of the sacrococcygeal joint showed the strongest correlation among all other parameters (Pearson's correlation coefficient: 0.63 in females, 0.68 in males). However, numerous studies have examined the relationship between PT and the SFP angle [ 8 9 10 11 24 ]. Our results also support the use of the SFP angle in the prediction of PT.…”

Study DesignCross-sectional study.PurposeThe purpose of this study was to evaluate the correlation between pelvic tilt (PT) and the sacro-femoral-pubic (SFP) angle, which is easier to identify than PT, in middle-aged and elderly Asian subjects from the general population.Overview of LiteratureMeasuring PT is important in the diagnosis and treatment of adult spinal deformity. However, identifying femoral heads, which are necessary to determine PT, using sagittal radiographs is often difficult.MethodsStanding coronal and sagittal pelvic radiographs of individuals aged more than 50 years were taken during a local medical examination. The subjects were divided into female, male, and total groups at the time of evaluation. Linear regression analysis was performed to investigate the relationship between PT and the SFP angle, which were obtained from the X-rays.ResultsThe present study included 291 subjects. There were no statistically significant differences between the left and right SFP angles, and there was gender difference regarding the SFP angle. However, a gender difference was observed regarding PT. The correlation between PT and the SFP angle was substantiated in each group. Pearson's correlation coefficients between PT and the SFP angle in the total, female, and male groups were 0.696, 0.853, and 0.619, respectively. In the linear regression analysis, PT was calculated as follows: PT=60.1−0.77×(SFP angle) in the total group, PT=62.8−0.80×(SFP angle) in the female group, and PT=51.5−0.64×(SFP angle) in the male group.ConclusionsA significant correlation between PT and the SFP angle was observed in middle-aged and elderly Asian subjects from the general population.
