Carpometacarpal Ligament Repair

Medically reviewed by Last updated on Mar 5, 2023.

CMC ligament repair is used to treat arthritis at the carpometacarpal joint. This is the area at the base of your thumb where your thumb bones meet your wrist bones. This surgery is also called ligament reconstruction and tendon interposition (LRTI).


Seek care immediately if:

  • Blood soaks through your bandage.
  • Your incision comes apart.
  • You have severe pain.

Contact your healthcare provider if:

  • You have a fever or chills.
  • Your wound is red, swollen, or draining pus.
  • You have questions or concerns about your condition or care.


You may need any of the following:

  • NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
  • Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Wound care:

Care for your wound as directed. When you are allowed to bathe, carefully wash the wound with soap and water. Dry the area and put on new, clean bandages as directed. If you have a cast, cover it when you bathe to keep it clean and dry. Ask your provider for more information about cast care.


  • Ice helps decrease swelling and pain. Ice may also help prevent tissue damage. Use an ice pack, or put crushed ice in a plastic bag. Cover it with a towel and place it on your thumb for 15 to 20 minutes 5 to 6 times a day or as directed.
  • Elevate your thumb above the level of your heart as often as you can. This will help decrease swelling and pain. Prop your thumb on pillows or blankets to keep it elevated comfortably.
  • Wear your cast or splint as directed. You usually have a splint and then a cast for a total of 6 weeks. Wiggle your fingers often to prevent stiffness.
  • Go to hand or physical therapy as directed. This usually starts at 6 weeks when the cast is removed. Therapists can teach you exercises to help improve movement and strength.

Follow up with your healthcare provider as directed:

You will need to return to have your stitches removed and a cast placed. Write down your questions so you remember to ask them during your visits.
