Amniotic band syndrome, or constriction ring syndrome, happens when a developing fetus gets tangled in the fibrous bands of the amniotic sac. Sometimes, fingers and toes can become trapped in these fibrous bands, with results ranging from amputation of the digits, to fusion of the fingers or toes, termed syndactyly. Syndactyly is amongst the most frequent congenital hand anomaly and is termed simple when the digits are connected by soft tissue only, and complex when one or more phalanges are fused. In complicated syndactyly, there are additional bony elements in between the digits making it challenging if not impossible to separate safely.

The patient in this case is a 1-year-old male with complex syndactyly of the left hand and simple syndactyly of the right hand. Here, both sides are released, with the left side involving a full-thickness skin graft taken from the patient’s groin crease. This case was filmed during a surgical mission with the World Surgical Foundation in Honduras.
