The typical recovery time for ulnar nerve surgery depends on the procedure, explains NYU Langone Medical Center. It takes up to three months to recover from submuscular transposition surgery. In comparison, patients who have simple decompression surgery can return to light office work a few days after the procedure.
After simple decompression surgery, patients can use their arms for light movement and activities. Patients should avoid gripping, pulling or pushing forcefully for at least four weeks after surgery, according to Erickson Hand Surgery.
After submuscular transposition surgery, the affected arm is placed in a sling, notes NYU Langone Medical Center. Patients can expect at least three months of physical therapy following this type of surgery.
