Complications of Radial Tunnel Release Surgery

Radial tunnel release surgery, also known as carpal tunnel surgery, is an outpatient procedure that opens the narrowing of the "tunnel" around the nerves that run from the arm into the hand. Complications rates vary by study, says the University of Maryland Medical Center (UMMC).

  1. Short-term Complications

    • As with any surgery, anesthesia poses a very small risk. An allergy to medications prescribed for pain after radial tunnel release is also possible. Infection of the surgical site and bleeding can also occur.

    Temporary Complication

    • Nerve damage, signified by tingling and numbness, in the weeks immediately following the surgery, is common and usually temporary. Check with your surgeon if it doesn't improve.

    Long-term Complications

    • If they occur, scarring, scar sensitivity and stiffness of the wrist can all be permanent, according to MedLine Plus.

    The Most Common Complication

    • About 10 percent to 33 percent of patients lose some wrist strength after radial tunnel release, and some begin to experience pain in the elbows and shoulders after the surgery, says UMMC.

    Failure: The Ultimate Complication

    • When radial tunnel release fails, pain and symptoms may return. In such cases, patients may undergo a repeat procedure. UMMC says patients who have the endoscopic version of the procedure are less likely to experience radial tunnel failure.
