General Procedure Information
Carpal Tunnel Release
Carpal tunnel release may be considered when median-nerve compression symptoms are severe, persistent or have not improved with non-operative care. Its aim is to reduce pressure on the nerve.
What Is It?
The carpal tunnel is a narrow wrist passage containing the median nerve and tendons. Release surgery divides the transverse carpal ligament that presses on the nerve, making more space. It may use a small open incision or endoscopy, with the choice explained individually.
When Might It Be Considered?
These are common assessment considerations only; they do not mean that you are necessarily suitable for surgery or the procedure.
- Repeated numbness, tingling or night symptoms in the thumb, index, middle or part of the ring finger match carpal tunnel syndrome
- Hand weakness, dropping objects, muscle wasting or clearly worsening sensation warrants early assessment
- Suitable non-operative care such as splinting, activity adjustment, medication or injection has not improved symptoms
What Are the Alternatives?
- Night splinting, reducing repeated bending or forceful grip, addressing relevant health conditions and, where suitable, injection treatment
- Symptoms may arise from the neck, another peripheral nerve or a different hand problem, so diagnosis should be confirmed first
General Assessment and Procedure Planning
The clinician examines the hand and wrist and may arrange nerve-conduction testing or imaging. The procedure may use local or another appropriate anaesthetic; incision, wound care and same-day discharge depend on the surgical plan and health status.
Important
Possible Risks and Limitations
All surgery and invasive procedures carry risks. Your actual risk depends on your condition, the scope of the procedure, health and other factors. Your doctor will discuss this individually during informed consent.
- Infection, bleeding, scar pain or sensitivity, palm tenderness and stiffness
- Injury to nerve, blood vessel or tendon, incomplete symptom improvement, recurrence or need for further treatment
- With long-standing severe symptoms or established nerve injury, sensation and strength may not fully recover
General Recovery Approach
After surgery, keep the wound clean as directed, return to hand use gradually and avoid early overloading. Improvement in numbness, sensation and grip varies with duration and severity of nerve compression; persistent stiffness or limitation may need hand rehabilitation.
When Should You Contact the Medical Team Promptly?
- Pain, swelling, redness or warmth becomes suddenly worse after surgery or injury
- Persistent wound bleeding or discharge, marked wound redness or swelling, fever, chills or feeling generally unwell
- New or worsening numbness, weakness, breathing difficulty, chest pain or marked calf pain/swelling
For severe illness, breathing difficulty, chest pain, fainting or inability to travel safely, call 999 or attend an emergency department immediately.
