We used coronal computed tomography to determine the normal sesamoid position in 20 healthy volunteers. The sample involved 40 feet (20 left [50%] and 20 right [50%]) in 20 volunteers, including 11 females (55%) and 9 males (45%).
The relationship between the first metatarsal head and the sesamoid complex was categorized as Yildirim grade 0 in every case (100%). The mean width of the foot was 77.7 ± 5.8 mm, and the ratio of the foot width to the distance from the second metatarsal head to the tibial sesamoid was 39.6% ± 2.02%. Based on our findings, we consider Yildirim grade 0 to be the normal sesamoid alignment.
