what is carpal tunnel release surgery?
Carpal tunnel syndrome occurs when the median nerve becomes compressed as it passes through the narrow tunnel at the wrist. This can lead to tingling, numbness, night-time symptoms, weakness, and difficulty carrying out fine motor tasks. For some individuals, splinting, physiotherapy, or injections provide temporary relief. However, when symptoms persist or begin affecting strength and daily function, carpal tunnel release surgery may be recommended to relieve pressure on the nerve.
At One Orthopaedics, we provide specialist assessment and surgical treatment for carpal tunnel syndrome, supporting patients across Guildford and Surrey. Our consultants offer minimally invasive and open techniques designed to reduce symptoms, restore normal nerve function, and improve quality of life with predictable recovery.
What Is Carpal Tunnel Release?
Carpal tunnel release is a surgical procedure that reduces pressure on the median nerve by opening the transverse carpal ligament. This increases space within the tunnel and prevents the nerve from being compressed during wrist movement. Conditions treated include:
- Numbness or tingling in the thumb, index, and middle fingers
- Night-time waking due to hand symptoms
- Weak grip strength
- Persistent pain or discomfort in the wrist or palm
- Worsening symptoms despite conservative treatment
The goal is to restore sensation, improve hand strength, and prevent long-term nerve damage.
Who Is It Suitable For?
Carpal tunnel release may be recommended for individuals who:
- Have persistent symptoms impacting daily life or sleep
- Experience worsening numbness or loss of coordination
- Show nerve changes on ultrasound or nerve conduction studies
- Have hand weakness or difficulty gripping objects
- Have not improved with splints, therapy, or injections
A consultant assesses symptoms and diagnostic tests to confirm suitability.
How the Procedure Works
Carpal tunnel release can be performed using:
- Open surgery: A small incision allows direct access to release the ligament.
- Minimally invasive (keyhole) techniques: Smaller incisions with the same functional outcome.
The surgeon gently divides the tight ligament, immediately reducing pressure on the median nerve. The skin is closed with stitches, and the ligament heals in a lengthened position over time.
Recovery and Rehabilitation
Recovery is typically straightforward, with most patients noticing early improvement in night-time symptoms. Normal finger movement is encouraged immediately, while heavier activity is gradually reintroduced.
Rehabilitation includes:
- Wound care and swelling management
- Early hand and finger mobility exercises
- Gradual return to lifting and gripping
- Strengthening when comfortable
- Return to work depending on job demands
Full recovery may take several weeks, particularly for those in manual roles.
Before and After Treatment
Before treatment, symptoms may include numbness, tingling, reduced grip strength, pain during wrist movement, and frequent night-time disturbance. These symptoms can limit typing, driving, lifting, or other daily tasks.
After treatment, many individuals experience significant improvement in sensation, reduced night pain, and better overall hand function. Early rehabilitation supports the recovery process and helps restore confidence in daily activity.
