title: A child presented with bilateral congenital constriction ring in lower extremity: a case report.
abstract: BACKGROUND
  The congenital constriction ring of lower extremity is very uncommon and rare condition. The actual incidence in general population is not known. In English literature, very few cases are reported time to time as congenital constriction band syndrome associated with musculoskeletal disorder like congenital talipes equino varus. The lesion can involve skin only or goes to deeper structure up to bone, which can lead to gangrene of foot or auto amputation.
  
  
  METHODS
  We are presenting a case of bilateral congenital constriction ring in lower limb who presented at age of 4 year without any other associated congenital anomaly, simply managed by Z-plasty, which improves quality of life after physiotherapy.
  
  
  CONCLUSIONS
  Congenital constriction ring of lower limb is extremely rare condition in children. Early diagnosis and management is mandatory, either in single stage or by stage procedure, to prevent auto-amputation of limb and to improve quality of life on feet.
