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… 


Sesamoid disorders of the hand.
The clinical importance of the sesamoid bones and possible pathological conditions are described to lead to a more accurate diagnostic process.
Prevalence of sesamoid bones in the interphalangeal joint of the thumb and fingers: A Radiographic Study
The knowledge that sesamoid bones occurs at these rates in the thumb IP joint and finger PIP joints is helpful to differentiate chip fractures from sesAMoid bones near the IP joint, including the PIP joint.
Ossa Sesamoidea - prevalence of sesamoid bones in human hands.
There was a significant difference in the prevalence of sesamoid bones between right and left hand in males in this study, and discrepancies of opinion regarding sesAMoid bones in morphological research are discussed.
Prevalence and variation of sesamoid bones in the hand: a multi-center radiographic study.
A retrospective review of posteroanterior and oblique radiographs of 436 left and 414 right hands of 850 adult patients obtained from four hospitals found two sesamoid bones were rarely seen in other joints of the hand except thumb MCP joints.
The prevalence of the sesamoid bones of the hand: A systematic review and meta‐analysis
The findings of this evidence‐based anatomical review provide quantitative evidence that the incidence of sesamoid bones in human hands depends on genetic rather than functional factors.
Prevalence and distribution of sesamoid bones in the hand determined using digital tomosynthesis
Most sesamoid bones in the hand were detected in MCP I, II, V, and IP I joints, and were more often detected on DTS than CR, suggesting DTS is a reliable tool to evaluate bony structures in the hands.
Distribution of Sesamoid Bones in the Hand—A Study in the Chinese Population: 研究中國人的手部籽骨分佈
The result revealed that the Chinese ethnic group had a higher prevalence of sesamoid bones at the 2nd and 3rd MCPJ when compared with other ethnic groups and the distribution of sESamoids bones was symmetrical in bilateral hands.

Relationships between pianists' hand biomechanics and the performance of a scale in thirds and Qualitative cross-sectional observation of individual profiles showed that experienced pianists perform with a higher degree of synchrony in two-note descent while pianists with organ training background play with a lesser degree of synchronization.
A new insight into the fabella at knee: the foetal development and evolution.
Using longitudinal semiserial sections of 12 lower extremities from 8 human foetuses at 15-18 weeks, foetal morphologies of the knee in specimens with and without fabellae are compared to discuss an evolutionary aspect of the fabella and plantaris muscle.
Fracture of the sesamoid bones of the thumb associated with volar plate injury: ultrasound diagnosis
A case of fracture of both the ulnar and radial sesamoids of the metacarpophalangeal (MCP) joint of the thumb and a lesion of the volar plate is reported.
