Duplicated longitudinal bracketed epiphysis 'kissing delta phalanx' in the hand.
The duplicated longitudinal bracketed epiphysis ("kissing delta") phalanx has been described rarely. These delta bones have a bizarre appearance and are often associated with other developmental abnormalities such as central polydactyly. We have seen a total of 13 kissing delta phalanges in the hands. We discuss their natural history, look at the associated anomalies and consider the treatment options for this very rare congenital anomaly.
