Amniotic band syndrome of the upper extremity: diagnosis and management.

Abstract

Amniotic band syndrome, a condition involving fetal entrapment in strands of amniotic tissue, causes an array of deletions and deformations. Band formation most frequently affects the distal segments, including the hand. Because of the heterogeneous nature of expression of this disease, treatment is individualized. Timing of repair and surgical planning are important in improving functional outcome. In the patient with distal edema and acrosyndactyly, early repair portends better prognosis. Improvements in prenatal diagnosis and fetoscopic surgical technique may eventually allow treatment of amniotic band syndrome in utero.
