title: Congenital constriction band syndrome.
abstract: Eighty-three patients with congenital constriction band syndrome were reviewed. Clinical manifestations and associated anomalies were analyzed with attention directed to distribution of the involvement. Constriction bands, amputation, and acrosyndactyly were the main clinical manifestations of this syndrome. Involvement of the distal portions of the extremity was most common. In the hand, the central digits were involved most frequently, and the thumb was only minimally affected in most cases. Of the 19 cases with an associated clubfoot deformity, 10 were proven to be a paralytic clubfoot due to compression neuropathy of the peroneal nerve caused by a deep constriction band below the knee, whereas 9 had a normal peripheral nerve.
