What to Do if a Fractured Limb Is Cold or Numb?

Assessment and Precautions

When assessing a fractured limb that’s cold or numb, prioritize preventing further injury and reducing pain. Avoid direct pressure on the fracture site as this can exacerbate swelling. If the individual is showing signs of shock (such as pale skin, fast pulse, or shallow breathing), call for emergency assistance.

Applying Heat

Apply a warm compress or heating pad to the affected area to warm the limb and increase blood flow. The recommended temperature range is 104°F (40°C) to 107°F (42°C). Use a thermometer to monitor the temperature and adjust as needed. Apply heat for 15 to 20 minutes at a time, with a 30-minute break in between to avoid burns. This can be repeated as necessary.

Splinting and Immobilization

Once the limb is warm and numbness has subsided, apply a splint to immobilize the affected area. Use a SAM splint or a rigid splint, such as a board or a roll of cloth. Secure the splint with bandages or tape to prevent movement and promote healing. Ensure the splint is not too tight, as this can cut off circulation. Monitor the individual for signs of improvement or worsening symptoms, and seek medical attention if the numbness persists or worsens.
