Brief summary

This study aimed to present the influence of unilateral and bilateral flat foot on coronal spinopelvic alignment in asymptomatic young healthy males. It will be carried out by examining the medical reports of individuals who apply to the National Health Board to work in positions requiring physical fitness between January 2018 and January 2019. Plain radiographies of the feet, pelvis, and spine will be analyzed. Calcaneal pitch angle (CPA) for flat foot, pelvic obliquity (PO), and Cobb angle (CA) for spinal asymmetry will be measured. After all analyzes were completed, participants will be divided into 2 groups as unilateral (UniFF) or bilateral (BiFF) flat foot, depending on the CPA measurements and will be compared.

Primary

MeasureTime frameDescription
Calcaneal pitch angle (CPA)BaselineCalcaneal pitch angle (CPA) is defined as an angle between a line drawn from the inferior of the calcaneocuboid joint to the inferior border of the calcaneus and a second line drawn from the inferior aspect of the sesamoid bones to the inferior border (13). CPA for both (right and left) foot was evaluated from all plain radiographs in this study and the angles equal to or less than 20 degrees were accepted as a flat foot.
Pelvic obliquity (PO)BaselinePelvic obliquity (PO) was measured by horizontal pelvic obliquity according to Osebold et al. from a posteroanterior radiograph. The angle between the line drawn between the most proximal points on the iliac crest and the line drawn parallel to the lower end of the radiograph was recorded.
The Cobb angle (CABaselineThe Cobb angle (CA) is a gold standard measurement for identifying the magnitude of spinal curves (14). Spinal curvature was measured from the standing full-length posteroanterior radiograph. The angle of the curve is measured as an angle between the perpendiculars of the lines parallel to the upper border of the upper vertebral body and parallel to the lower border of the lowest vertebral body of the curve (16). Straight or symmetrical spines in the coronal plane were accepted as a normal spine, and curves\<10 degrees accepted as spinal asymmetry, and the curves ≥ 10 degrees accepted as scoliosis (15). Spinal curve patterns in coronal planes were classified according to the Scoliosis Research Society classification. The curve was classified as single in terms of one curve exists in the thoracal or lumbal spine; as double in terms of one curve exist the through thoracal and lumbal spine; and as triple that exists through upper thoracal, middle thoracal and lumbal spine (17).
