[Hyperphalangia in Pierre-Robin syndrome].

Pierre Robins syndrome associated with symmetric hyperphalangia of the index fingers is called Catel-Manzke syndrome. Connate radial deviation of the index fingers is caused by an odd bone. The deformity is demonstrated by two personal cases. The deviation is progressive and because of increasing functional limitation the operative correction of the index fingers at the age of 2-3 years is advised. Surgical technique and success of treatment are presented.
