What Is A Guyon Tunnel Release?

Surgeons perform Guyon tunnel release, also known as ulnar tunnel or ulnar canal release, to alleviate pressure on the ulnar nerve as it traverses through Guyon’s canal or tunnel in the wrist. The ulnar nerve, a major nerve in the arm, governs sensation and controls specific muscles in the hand.


Guyon tunnel release becomes necessary when the ulnar nerve faces compression or irritation while passing through Guyon’s canal in the wrist. This condition, known as ulnar tunnel syndrome or Guyon’s canal syndrome, can arise from several factors, including repetitive wrist movements, direct trauma, or pressure exerted on the nerve by surrounding structures.


Surgeons typically perform the surgery under local or regional anesthesia, with or without sedation, depending on the patient’s condition and preferences. Throughout the procedure, the surgeon incises over the Guyon’s canal to expose the ulnar nerve. Subsequently, the surgeon carefully dissects and releases the transverse carpal ligament, which forms the roof of the Guyon’s canal, to create more space for the nerve. Any compressive structures or scar tissue pressing on the nerve are also removed. Following the release, the surgeon closes the wound with stitches and applies a dressing to protect the surgical site during the initial healing phase.


The recovery time after Guyon tunnel release varies depending on the extent of nerve compression and the patient’s overall health. Healthcare providers may recommend physical therapy or hand rehabilitation to enhance wrist strength and flexibility and to promote nerve gliding. Full recovery may take several weeks to months, and the patient’s hand function should gradually improve during this time.


Various factors, including the severity of ulnar nerve compression and the patient’s compliance with postoperative care and rehabilitation, determine the success of Guyon tunnel release. In many cases, this procedure offers significant relief from ulnar nerve symptoms and enhances hand function.

When conservative treatments have not been successful, healthcare providers generally consider Guyon tunnel release a safe and effective treatment for ulnar tunnel syndrome. However, like any surgical procedure, Guyon tunnel release carries risks, and patients should thoroughly discuss the benefits, risks, and potential complications with their surgeon before proceeding. A qualified hand surgeon experienced in treating nerve compression conditions should perform the procedure to achieve the best possible outcomes.
