Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

• Congenital coalition of carpal bones is a common anomaly that is usually discovered on imaging obtained for unrelated reasons.
• The lunate and triquetrum are most likely to show such coalition. ^{[1] [2]}
• It is reported twice as frequently in women.
• It may occur as an isolated entity or as part of a syndrome and may show a familial pattern.
• It is caused by a failure of separation or segmentation of the carpal bones.
