Abstract

PURPOSE
To determine the normative data for the pelvic morphology parameters in the young Korean female population. MATERIALS AND METHODS: Young Korean female patients in 20s and 30s who had visited the outpatient clinic for a first attack acute sprain underwent a telephone interview at a minimum of 1 year after their last hospital visit. Those who had recovered completely and had no back-related complaints were selected for the pelvic lordosis angle (PRS1)and pelvic angle of incidence (AOI)measurements (n=40 each age group). RESULTS: There was no age difference in both parameters. The PRS1 in the young female population was 38.7+/-8.3 degrees (range: 13.6-52.9 degrees and the AOI was 48.5 +/-9.4 degrees(range: 30.5-74.7 degrees, which shows a close correlation between the two parameters (correlation coefficient, r=-0.965). The linear regression equation obtained is as follow; Equation I: PRS1=79.909-0.850 x AOI, Equation II: AOI=90.902-1.096xPRS1 (linear regression analysis, p=0.000, R2 =0.931). CONCLUSION: The data obtained from the study may be used for future studies related to the sagittal spinopelvic balance.
