Splint/castConstructionIndicationsAdvantagesRisks/disadvantages
SplintNoncircumferential
  • Acute and definitive treatment of select fractures

  • Soft tissue injuries (sprains, tendons)

  • Acute management of injuries awaiting orthopedic intervention

  • Allows for acute swelling

  • Decreased risk of complications

  • Faster and easier application

  • Commercial splints available and appropriate for select injuries

  • May be static (preventing motion) or dynamic (functional; assisting with controlled motion)

  • Lack of compliance

  • Increased range of motion at injury site

  • Not useful for definitive care of unstable or potentially unstable fractures

CastCircumferential
  • Definitive management of simple, complex, unstable, or potentially unstable fractures

  • Severe, nonacute soft tissue injuries unable to be managed with splinting

More effective immobilization
  • Higher risk of complications

  • More technically difficult to apply
