title: Lipoinjection and Multiple Internal Cuts for Congenital Constriction Bands: A New Treatment Approach.
abstract: BACKGROUND
  Traditional treatment for a congenital constriction band of the limb involves multiple Z-plasties and W-plasties. We propose an alternative surgical procedure for the treatment of congenital constriction bands that obviates the need for Z-plasties and eliminates the constriction band.
  
  
  METHODS
  We present the case of a 36-year-old woman with a congenital constriction band of the leg. Using a minimally invasive approach, the skin segment that included the band was dissected from the deep tissues. Afterwards, multiple slices were performed on the internal surface of the fibrous ring. This and lipoinjection were used to reverse the depression that characterizes the "hourglass sign" and homogenize the skin surface.
  
  
  RESULTS
  Results have remained stable in a follow-up period of 18 months.
  
  
  CONCLUSIONS
  This surgical alternative can be considered as an option for the treatment of congenital constriction bands. It is a safe, reproducible procedure that does not cause additional scars and has good functional and aesthetic results.
