This study aimed to obtain reference values of lumbar lordosis (LL) and lower LL (LLL) from normal asymptomatic groups, determine the relationship between them pelvic incidence (PI), establish predictive formula for ideal LLL in elderly Korean population. Standing plain lateral radiographs whole spine, including pelvis, were analyzed adult male volunteers without back pain or prior surgery involving spine extremity. Volunteers with scoliosis, spondylolisthesis, segmental disk space narrowing, and/or compression fractures excluded. The following parameters measured: LL, LLL, PI. PI–LL PI–LLL calculated, using stepwise multiple regression analysis was made. A P value < 0.05 considered statistically significant. participants included 150 volunteers. All an average age 64.1 ± 6.4. height, weight, body mass index 167.0 5.5 cm, 67.3 9.8 kg, 24.1 3.1 kg/m2, respectively. − 57.5° 9.0°, 41.7° 7.0°, PI 48.6° 8.6°. established as follows: = 0.38 × 27.61 (R2 0.172), 0.77 28.69 0.516), 0.62 + 0.348), 0.225 28.63 0.083). inconsistent, they have a positive correlation Our data would be helpful according These slides can retrieved under Electronic Supplementary Material.
