A pedigree with unusual anomalies of the elbows, wrists and hands in five generations.

Although congenital deformities of the upper extremity occur commonly, their classification is difficult because they display numerous individual variations and combinations. It is generally thought that these anomalies are inherited, and we have been able to record a series of 5 members of a White family with unusual symmetrical bilateral congenital anomalies of the elbows, \\'fists and fingers. The family pedigree (Fig. 1) clearly shows this to be a case of autosomal domiIiant inheritance with complete penetrance. Ten members of the family were known to be affected, 4 males and 6 females. We have examined 3 males aged respectively 31 years, 24 years and 7 years, and 2 females aged 6 years and 2 years.
