Abstract

BACKGROUND : To date, only a few studies have analyzed the differences in spinopelvic alignments between male and female. METHODS: Ninety-eight healthy girls and boys were evaluated. Their spinopelvic parameters measured and compared via X-ray scan in standing posture. Investigated parameters were thoracic kyphosis (T1-T12), lumbar lordosis (L1-L5), thoracic tilt (TT), lumbar tilt (LTLT), pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS) and sagittal balance (SB). Student's t-test was used to determine relationships between parameters. RESULTS: Forty-eight girls (49) and 50 boys (51) were evaluated. Mean height and weight were 153.6 +/- 15.6 cm and 49.9 +/- 13.1 kg, respectively. No statistically significant differences were found in spinal (TK, TT, LT) or the pelvic and spinopelvic parameters (PI, SS, PT) between the sexes except lumbar lordosis (LL). Spinal balance parameters (SB) were not found to be significantly different between males and females; LL was higher in females. LL in males was 36.6 and in females were 42.77 (P=0.013). CONCLUSIONS: No significant differences were found in spinal and spinopelvic parameters and spinal balance parameter between the genders in age 8-19 years, except lumbar lordosis (LL) that was higher in female group.
