Name of the Procedure:

  • Common Name(s): Splint

A splint is a device used to immobilize and support a body part, often following an injury or surgery. It helps to keep the affected area in place to ensure proper healing.


  • Medical Conditions: Fractures, sprains, strains, post-operative support, and other musculoskeletal injuries.
  • Goals: To immobilize the injured area, prevent further injury, reduce pain, and promote proper healing.


  • Symptoms/Conditions: Acute fractures, severe sprains, joint dislocations, soft tissue injuries, and post-operative protection.
  • Patient Criteria: Those experiencing pain, swelling, or instability in an injured area that requires immobilization.


  • Instructions: No specific fasting or medication adjustments are typically required.
  • Diagnostic Tests: X-rays or other imaging studies may be necessary to ascertain the extent of the injury.

Procedure Description

  1. Assessment: The healthcare provider evaluates the injury and decides on the type of splint needed.
  2. Preparation: The injured area is cleaned and, if necessary, covered with a protective layer of padding.
  3. Application: The splint material is molded and applied around the injury. It may be made of plaster, fiberglass, or thermoplastic materials.
  4. Securing the Splint: The splint is secured with bandages or wraps to maintain immobilization.
  5. Adjustment: The fit of the splint is checked to ensure it is snug but not too tight.
  • Tools/Equipment: Splinting materials (plaster, fiberglass, thermoplastic), bandages, padding.
  • Anesthesia/Sedation: Generally not required; local anesthesia may be used if pain management is needed during application.


  • Typical Duration: 20 to 30 minutes.


  • Performed At: Hospital emergency rooms, outpatient clinics, or physician offices.


  • Healthcare Professionals: Physicians, physician assistants, nurse practitioners, orthopedic technicians.

Risks and Complications

  • Common Risks: Skin irritation, swelling, discomfort.
  • Rare Risks: Compartment syndrome, pressure sores, reduced blood flow.
  • Management: Regular monitoring, adjustment of the splint, prompt medical attention for severe symptoms.


  • Expected Benefits: Immobilization of the injury, reduced pain, protection and stabilization of the affected area.
  • Timeframe: Immediate immobilization with pain relief typically within a few hours.


  • Post-Procedure Care: Keep the splint dry and clean, avoid putting pressure on the splint, follow-up with healthcare provider as directed.
  • Recovery Time: Varies depending on the injury; typically a few weeks to several months.
  • Restrictions: Limited use of the affected limb or area, follow specific activity restrictions as advised by healthcare provider.
  • Follow-up: Regular check-ups to monitor healing and adjust the splint if necessary.

  • After Procedure: Gradual reduction in pain as the splint immobilizes the injury; might experience itching or pressure which can be managed by repositioning or adjusting the splint.
