Removal of a ring trapped on a finger may require use of a manual ring cutter.

A ring cutter should be tried whenever there is excessive swelling, evidence of finger ischemia, or when other methods fail.

Indications

  • Edema or anticipated edema when ring will not slide off finger

  • Rings made of soft materials (eg, gold, silver, copper, plastic)

Contraindications

  • None

Complications

  • Laceration of underlying tissue

Equipment

  • Nonsterile gloves

  • Mild antiseptic cleanser (eg, 2% chlorhexidine)

  • Manual ring cutter

  • Hemostat or pliers

  • Eye protection (eg, face mask, goggles)

  • Sometimes a powered ring cutting saw or a bolt cutter

Additional Considerations

Relevant Anatomy

  • The site of maximum diameter (and obstruction to removal) is the proximal interphalangeal (PIP) joint.

Positioning

  • Patient comfort with excellent exposure of ring on finger

Step-by-Step Description of Procedure

  • First, clean the surrounding skin with a mild antiseptic cleanser such as chlorhexidine.

  • Slide the manual ring cutter's small hook (guard) under the ring to position the saw-toothed wheel that cuts the metal.

  • Position the saw-toothed wheel over the ring and cut through it, if necessary, a little bit at a time.

  • Spread apart the cut ends of the ring with a large hemostat or another tool (eg, pliers) and remove it.

Aftercare

  • Clean any finger lacerations gently with a clean cloth or gauze and soap and water or a mild antibacterial wound cleanser such as chlorhexidine. Suture or bandage with gauze if protection is needed.

  • A jeweler can usually repair rings cut in one or more places.

Warnings and Common Errors

Be aware of signs of finger ischemia, which is usually caused by the ring and indicates an urgent need to remove the ring:

  • Mottling

  • Blue-gray or white color of the distal digit

  • Very prolonged or absent capillary refill

  • No distal pulse by pulse oximetry

  • Severe pain

Tips and Tricks

  • Remind the patient to remove all rings before finger edema develops and is extensive enough to cause pain or vascular compromise if there is ever risk of a finger injury.

  • If the tension is too great to spread the ring, another cut 180° from the original cut site can be made. This second cut allows the ring to fall off in two pieces.

  • For rings made of hard material, one person can pull on each side of the ring to open it; each can use a paper clip.
