Carpal coalition
Introduction
- 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.
