The prevalence of the sesamoid bones of the hand: A systematic review and meta‐analysis

摘要: The literature contains various estimates of the prevalence and distribution sesamoid bones in hands. aims this systematic review are to provide a better estimate frequency hand sesamoids its association with variables such as ancestry, gender, side. Nineteen studies met inclusion criteria. pooled rates sensitive meta-analyses from large-sample adults showed: (a) true overall 99.9% for metacarpophalangeal (MCP) joint thumb (MCP-I), 53% interphalangeal (IP-I), 43.4% MCP index (MCP-II), 1.47% medius finger (MCP-III), 0.6% ring (MCP-IV), 67.7% auricular (MCP-V); (b) radiological radial sesamoid, 99.6% ulnar 47.8% IP-I, 40% MCP-II, 1.3% MCP-III, 0.8% MCP-VI, 62.8% MCP-V. Black, Middle Eastern, European ancestries conferred significantly higher frequencies at MCP-V, respectively. There was significant female gender MCP-IV, ORs 1.53, 4, 1.3, respectively, nonsignificant "female" trend other locations. no children aged 10-17 years were 92.7, 42.2, 33.8, 0.5, 0.3, 36.5% MCP-I, findings evidence-based anatomical quantitative evidence that incidence human hands depends on genetic rather than functional factors.
