  • summary
    • Congenital Amputations are upper extremity amputations that are most commonly associated with amniotic band constriction. 
    • Diagnosis is made clinically with a variable location of amputation.
    • Treatment depends on the level of amputation and may be addressed with prosthesis placement as necessary. 
  • Epidemiology
    • Incidence
      • rare
    • Anatomic location
      • transradial is the most common location
  • Etiology
    • Pathophysiology
      • due to failure of formation
    • Genetics
      • no clear genetic involvement
    • Risk factors
      • amniotic band constriction
    • Associated conditions
      • typically not associated with systemic conditions
  • Presentation
    • Symptoms
      • usually painless
      • functional deficits
    • Physical exam
      • varies depending on location of amputation
  • Imaging
    • Radiographs
      • AP and lateral of affected extremity
  • Treatment
    • Nonoperative
      • prosthesis placement
        • indications
