Objective:

A radiological analysis of the spinopelvic paramaters and sagittal balance in a young adult Turkish population.

Method:

From radiology archive, full lateral spinal radiographs were scanned. The individuals who had no diagnosed of structural spine abnormality and no sign about spinal disorder from medical records were measured by Surgimap software on digital radiography. Sagittal spinal parameters (SVA, TK, LL) and Spinopelvic parameters (PI, PT) were measured. The unpaired t-test was used for comparison of measurements of genders. p<0.05 considered as statistically significant.

Results:

A total of 860 full lateral spine radiographs in the database were assessed and finally, 126 individuals (72 female, and 54 male) were included in the study who met all the criteria. The mean age was 27.4 ± 6.88 (range 20-40). The mean sagittal vertical axis (SVA), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), and pelvic tilt (PT) were -46.9 mm ± 19.83, 35.5° ± 5.47, 57.8° ± 9.10, 47.4 ± 9,13, and 13.37 ± 7.32, respectively. The PI (p=0.012), and TK (p=0.010) values between females and males were statistically significant, but SVA (p= 0.26), PT (p= 0.32), and LL (p=0.43) were not.

Conclusion:

This study was yielded to determine normative values of spinopelvic parameters in young adult Turkish population that would assist the clinical practice of spinal surgeons. The PI was found to be lower while LL was the same compared to the current literature from other countries and further studies were needed to clarify.
