Duplicated longitudinal bracketed epiphysis "kissing delta phalanx" in Rubinstein-Taybi syndrome.
A duplicated longitudinal bracketed epiphysis or the "kissing delta" phalanx is not well recognized in the world literature. This represents complex double-delta bones with a longitudinal epiphyseal bracket. This complex is composed of a back-to-back fusion of adjacent delta bones enclosed in a bracket. The convex side of each delta phalanx faces the other; hence the term kissing-delta bone. These delta bones have a very bizarre appearance and are associated with the Rubinstein-Taybi syndrome. We have seen a total of 36 kissing-delta phalanges in the foot. We discuss the natural history and treatment options of this very rare congenital anomaly. This is not a surgical-outcome study, but surgical treatment is observed.
