This will avoid any problems to the distal circulation in the limb, which may already be compromised. Lymphedema, when present, will significantly improve within a few weeks of the first surgery. "For the direct closure of the defect after dissecting a constriction band there are two techniques:

Triangular flaps; For this technique the circumference between the two borders must be measured. Depending on the difference the number of triangular flaps can be decided. With a triangular flap you can create more skin. Z-plasty or W-plasty; "Z-plasty is a plastic surgery technique that is used to improve the functional and cosmetic appearance of scars. It can elongate a contracted scar or rotate the scar tension line. The middle line of the Z-shaped incision (the central element) is made along the line of greatest tension or contraction, and triangular flaps are raised on opposite sides of the two ends and then transposed. "In rare cases, if diagnosed in utero, fetal surgery may be considered to save a limb that is in danger of amputation or other deformity. This operation has been successfully performed on fetuses as young as 22 weeks. The Melbournes Monash Medical Centre in Australia, as well as multiple facilities in the United States of America, have performed successful amniotic band release surgery. Reconstructions and prosthetics
Treatment usually occurs after birth and where plastic and reconstructive surgery is considered to treat the resulting deformity. Plastic surgery ranges from simple to complex depending on the extent of the deformity.
When the constriction cuts off the blood supply to the fingers, the fingers can form a peak with the most palmar digit being the index finger. Normal neurovascular bundles are not present in the distal parts. Hands with fused fingers need to be released in phases to preserve the distal blood supply. Paterson IVOne of the most severe consequence of constriction strains is probably intrauterine amputations, this is where the constriction goes as deep as the bone and cuts off the blood supply of the proximal extremity. The result will be that the developing toe or finger will become ischemic and fall off. Because the result is a transverse amputation that cuts off the vascular supply to the developing extremity, the actual constriction ring is not seen. This can result in different outcomes:

complete resorption; this is the most common form of amputation. In this form the amputated digit is completely resorbed during intrauterine development and therefore the amputated digit cant be found. recovery of the digit; the digit is recovered with the placenta during delivery. engraftment elsewhere; the amputated digit can be, in rare cases, engrafted somewhere on the fetus.Intrauterine deathIn extremely rare cases a strain can form around the umbilical cord and cut off the blood supply to the fetus which will result in intrauterine death.
