BACKGROUND: The sesamoid bones are small, usually oval bone structures often found in joints and under the tendons. Although their precise function is not fully understood, it is agreed upon that they protect the joints and make movements faster and less energy consuming. Sesamoid bones are found in hands, especially around first, second and fifth metacarpophalangeal joint and the interphalangeal joint of the thumb. MATERIALS AND METHODS: This study compares a group of 32 young musicians to 30 non-musicians of similar age and posture. The hands of the subjects were examined by ultrasound imaging for the presence of sesamoid bones. The results were noted and observed sesamoids were measured. RESULTS: The results seem to prove that although there are no difference in the amount or the location of the sesamoid bones between the musicians and the non-musicians, there is statistically significant tendency for the musicians to have bigger sum of the sesamoid's volume per hand (Fisher's test p-value = 0.034 < 0.05). CONCLUSIONS: There was also observed an unusually shaped "Bactrian" sesamoid bone at the interphalangeal joint of the thumb in 8 cases in the musicians' group and 1 case in the control group. All participants with the aforementioned structure were female.
