Constriction rings, or amniotic bands, form partial or complete circumferential constrictions around limbs or digits. Occurs sporadically; affects one in 15,000 live births

SYMPTOMS 

Fusion of distal fingers ( acrosyndactyly ),Terminal absence or amputation 

 Localized swelling with oedema distal to the constrictions.

OPERATIVE PROCEDURE

Excision of the constriction band and soft tissue release with Z or W plasties is done for most cases. Traditionally, no more than half the circumference was released at one sitting due to risk of distal ischaemia.  However, complete circumferential release can be performed safely

This complication can be easily avoided by performing surgery under loupes magnification, aseptic technique, and postoperative care and by performing operation by properly trained plastic surgeon.

2. At what age should surgery be performed?

Usually, six months to one year but in case of digital ischaemia , early intervention is required.

3. What is the approximate duration of the procedure?

One to two hours, but it depends on the number of figures involved.

4. What setup is required for the procedure?

A patient is required for the procedure and usually the patient admits for one to two days.
