Ulnar nerve transposition is a surgery to move a nerve at the elbow. A new path will be made for the nerve to sit in.
Reasons for Procedure
This surgery is done in people with cubital tunnel syndrome. This happens when there is pressure on the ulnar nerve inside the elbow. It can lead to tingling and weakness in the arm. This surgery will ease the pressure on the nerve.
|Pressure on the ulnar nerve can cause problems in the pinky and ring fingers of the hand.|

At the Care Center
After surgery, the staff may:

- Put ice on the elbow to ease swelling
- Apply a splint, bandages, and dressing to support the area
During your stay, staff will take steps to lower your chances of infection by:
- Washing their hands
- Wearing gloves or masks
- Keeping your incisions covered
There are also steps you can take to lower your chances of infection, such as:
- Washing your hands often and reminding visitors and staff to do the same
- Reminding your care team to wear gloves or masks

It will take a few weeks for the elbow to fully heal. Some activity will be limited for up to 4 weeks.
