Congenital constriction band syndrome

Abstract

There are many theories regarding the etiology of this rare syndrome. However, the current thinking is that these bands result from rupture of the amnion that causes permanent constrictions of extremities or amputations in utero. This clinically resembles temporary strangulation of an appendage by hair or thread, and must be distinguished. A historical overview as to the etiology of constriction bands will be presented, as well as case studies.
