Overview
This module describes how to remove a ring on a digit when a ring cutter is not available.
Indications
Non-removable ring
Contraindications
Finger fractures or significant soft tissue damage—consult surgery
Tissue necrosis distal to the ring—consult surgery
Patient information and consent
Always verify your patient’s identity and obtain informed consent before proceeding.
How do I explain this procedure?
“I'm going to try removing your ring using a string and some lubricant.”
What can my patient expect?
“If necessary, I can give you an injection for pain. I’m going to first squeeze the fluid out of your finger with an elastic cord, then I will wind the string around your finger and under your ring. As I pull the string, your ring will travel over the string and hopefully come off.”
What is my patient’s role?
“Tell me if this is very painful and you need an injection for pain. Otherwise, try to keep still and calm.”

proximal to the ring if required.
Lubricate the ring thoroughly and attempt to remove it with a twisting motion.
Wrap the Penrose drain or elastic bandage around the finger from tip to base. Leave for 5 minutes.
Remove the wrap.
Feed the end of the string/tie/floss under the ring with the haemostat.
Firmly wrap the distal end around the finger multiple times, from the ring, over the PIP joint, to the middle of the middle phalanx. Each wrap should be adjacent to the other.
Pull on the proximal end of the string, pulling towards the fingertip, so that the string unravels and the ring travels down the finger.
If this does not remove the ring, obtain a ring cutter or consult surgery.
Dispose of medical waste safely.
Record the completion of the procedure in patient notes.
Risks
Digital nerve injury
Skin abrasions or other wounds
