Which condition is described as rupture of the amnion leading to limb entanglement and potential amputations?

• A. Amniotic band syndrome
• B. Beckwith-Wiedemann syndrome
• C. Turner syndrome
• D. Patau syndrome

Answer: (A)

Rupture of the amnion can release fibrous strands into the amniotic cavity that May wrap around a developing limb or digit. These amniotic bands constrict blood flow and tissue, causing entanglement and damage that can range from subtle indentations to severe ischemia and even limb amputation. This is a mechanical, extrinsic issue rather than a chromosomal problem, which is why it presents with limb constriction rather than systemic anomalies. In contrast, Beckwith-Wiedemann syndrome is an overgrowth condition with features like macroglossia and omphalocele; Turner syndrome involves a missing sex chromosome (45,X); Patau syndrome is trisomy 13 with multiple severe anomalies.
