Constriction Band Syndrome

This is a pediatric patient who presented with deformity of the index and middle fingers. Radiographs of the hand were obtained. There is constriction of the soft tissues of the middle finger with partial amputation of the middle phalanx and complete absence of the distal phalanx. There is also partial constriction of the soft tissues of the index finger with preservation of the phalanges. Findings are consistent with constriction band syndrome. This syndrome is due to partial rupture of the amnion in utero which leads to formation of bands which can entrap and stunt the development of fetal parts.
