Congenital juxtaposition of two or more fingers with some or all of their tissue components congenitally pathologically connected is a congenital syndactyly, which is the second most common congenital malformation of the hand after polydactyly. The clinical manifestations of this condition often occur between the third and fourth fingers. In mild cases, there is only a skin webbing between the two fingers, which resembles a duck palm. In severe cases, the nails and phalanges may be fused with each other, and in a few cases, the phalanges may be poorly segmented or have too many knuckles. In some cases, the entire development of the affected hand is delayed. In a few cases, short fingers, ipsilateral pectoralis major and 2 to 5 ribs are absent, which is called Poland syndrome. Treatment of this syndrome requires plastic surgery. The duration of surgery depends on the degree of deformity. Fingertip syndactyly is a major obstacle to finger development and should be operated early. Surgery is usually successful at school age. Care must be taken in the design of the flap during surgery, which often requires a skin graft.
