Z plasty for constrictive ring syndrome: Case report

Constrictive ring syndrome is a congenital anomaly characterized by superficial or deep circumferential constrictions along the extremities. its etiology is obscure, but intrauterine amniotic bands have been incriminated. constructive rings can partially or totally wind around the limbs. if deep enough, they can totally obliterate the extremity. while simple and superficial constrictions do not require surgery, deep scatrized constrictive rings need to be excised. in this study, a case in which z plasty has been applied to correct a contour deformity following removal a constrictive ring on the distal third of a right leg has been presented.
