What is Carpal Tunnel Syndrome?

Carpal tunnel syndrome (CTS) is a condition caused by compression of the median nerve as it travels through the carpal tunnel in your wrist. The carpal tunnel is a narrow passageway formed by bones and ligaments on the palm side of your wrist. Compression of the median nerve can cause numbness, tingling and weakness in the hand and fingers. The condition typically develops gradually and can affect one or both hands.

Causes

Carpal tunnel syndrome occurs when pressure on the median nerve increases within the carpal tunnel. This can happen due to:

Swelling of the flexor tendons that pass through the tunnel
Thickening of the transverse carpal ligament
Fluid retention causing tissue swelling
Anatomical variations that makes the tunnel naturally smaller
Direct trauma or injury to the wrist area

Risk Factors

Several factors increase your likelihood of developing carpal tunnel syndrome:

Repetitive hand motions: Such as typing, assembly work, or using vibrating tools
Wrist position: Prolonged extreme flexion or extension
Medical conditions: Diabetes, rheumatoid arthritis, thyroid disorders
Pregnancy: Hormonal changes and fluid retention
Gender: Women are more likely to develop CTS than men
Age: Most common between ages 40-60
Obesity: Excess weight increases risk
Previous wrist injury: Such as fractures or dislocations
Workplace factors: Poor ergonomics or repetitive tasks

Signs & Symptoms

Mild Symptoms

Occasional tingling in thumb, index, and middle fingers
Mild numbness that comes and goes
Slight discomfort after prolonged computer use
Relief when shaking the hand
Minor difficulty with fine motor tasks

Moderate Symptoms

Frequent numbness extending to ring finger
Night-time pain or waking due to hand discomfort
Dropping objects occasionally
Weakened grip strength
Pain radiating up the forearm
Symptoms persisting throughout the day

Severe Symptoms

Constant numbness in affected fingers
Marked weakness in the thumb
Visible wasting of thumb muscles
Complete loss of sensation in fingertips
Inability to perform basic tasks
Pain extending up to the shoulder

Symptoms typically begin gradually and worsen over time without treatment. Many patients first notice symptoms at night, as certain sleeping positions can increase pressure on the median nerve.

When to See a Doctor

You should consider consulting an orthopaedic specialist if you experience persistent numbness or tingling in your fingers lasting more than a few weeks. Seek medical attention promptly if you notice sudden weakness in your hand, difficulty gripping objects, or visible muscle wasting at the base of your thumb. It is important to get checked if your symptoms are making daily activities or work duties more difficult to manage.

During your first consultation, our specialist will perform a comprehensive evaluation, including a detailed medical history and physical examination. This assessment helps determine the severity of nerve compression and identifies the appropriate treatment approach. Seeking treatment early often allows for more conservative management options and better outcomes.

Diagnosis & Testing Methods

Diagnosing carpal tunnel syndrome involves a combination of clinical evaluation and diagnostic tests. The specialist will begin with a physical examination, which may include tests such as Tinel’s sign (tapping over the median nerve) and Phalen’s test (wrist flexion test) to reproduce symptoms of nerve compression.

Further investigations may include nerve conduction studies (NCS) and electromyography (EMG), which measure how efficiently electrical signals travel through the median nerve and assess any associated muscle involvement. These tests involve small electrical impulses and typically take about 30–45 minutes.

Ultrasound imaging may be used to visualise the median nerve and surrounding structures. This non-invasive test can show nerve swelling and help rule out other conditions. In some cases, MRI scans may be recommended in selected cases to evaluate soft tissues and exclude other causes of wrist pain. Results are typically available within a few days, allowing for prompt treatment planning.

Treatment Options Overview

Conservative Management

Physical therapy and ergonomic adjustments are often the first steps in managing carpal tunnel syndrome. Exercises that improve nerve mobility and reduce compression can be prescribed. Workplace assessments may also help identify and correct ergonomic issues contributing to symptoms.

Wrist Splinting

Wearing a wrist splint, especially at night, helps keep the wrist in a neutral position, reducing pressure on the median nerve. Custom-fitted splints often provide better support than over-the-counter options. Splints may be recommended for several weeks, with many patients experiencing improvement in symptoms.

Medications

Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to relieve inflammation and pain. These medications work well for mild symptoms or when combined with other treatments. Our specialist will recommend appropriate dosages based on your condition severity.

Corticosteroid Injections

Steroid injections directly into the carpal tunnel can provide significant relief lasting several months. This treatment reduces inflammation around the median nerve. Injections are usually given under ultrasound imaging guidance for accuracy.

Platelet-Rich Plasma (PRP) Injections

PRP therapy involves using a concentration of your own platelets to help reduce inflammation and support tissue healing around the median nerve. These regenerative approach may help reduce inflammation and promote healing.

Carpal Tunnel Release Surgery

If symptoms persist despite conservative care, surgery may be considered. The procedure involves releasing the transverse carpal ligament to reduce pressure on the median nerve.

Endoscopic Surgery

Minimally invasive endoscopic surgery uses smaller incisions and specialised instruments. This technique typically results in less post-operative pain and faster recovery. Most patients can return to light activities within 2-3 weeks. Endoscopic release is a minimally invasive procedure that uses smaller incisions and specialised instruments. This approach may allow a quicker return to light activities compared with open surgery, with many patients resuming light tasks within 2–3 weeks.

Post-Surgical Rehabilitation

Rehabilitation following surgery helps restore function and prevent stiffness. This may include exercises to improve movement, nerve gliding, and gradual strengthening. Recovery time varies depending on the type of surgery and individual needs.

Complications if Left Untreated

If carpal tunnel syndrome is not assessed or managed, symptoms can gradually worsen over time. Persistent compression of the median nerve may lead to lasting numbness and reduced sensation in the affected fingers.

Prolonged nerve pressure can also cause thinning or wasting of the thenar muscles at the base of the thumb. Once muscle tissue is lost, full recovery is not possible, which can reduce grip strength and overall hand function.

Long-term nerve compression may lead to irreversible changes in nerve structure. Patients with severe untreated CTS often develop permanent disability affecting their ability to work and perform daily tasks. Early intervention prevents these serious complications and preserves hand function.

Prevention

Preventing carpal tunnel syndrome involves proper hand and wrist care, workplace ergonomics, and management of underlying health conditions. Maintaining a neutral wrist position while typing or using a mouse, taking regular breaks, and performing gentle hand and wrist stretches can help reduce strain. Using ergonomic tools, alternating repetitive tasks, and wearing wrist supports during activities that stress the wrist may also lower risk.

Additionally, regular exercise, maintaining a healthy weight, and managing conditions such as diabetes or thyroid disorders can support overall nerve health and reduce the likelihood of developing CTS.

Frequently Asked Questions

How long does carpal tunnel syndrome treatment typically take?

Treatment duration varies depending on severity and treatment type. Conservative treatments like splinting and physiotherapy typically require 6-12 weeks to show improvement. Corticosteroid injections may provide relief for several months. For surgical treatment, many patients notice significant improvement within 6-12 weeks post-surgery.

Can carpal tunnel syndrome affect both hands?

Yes, CTS can develop in both hands, though one hand is often more affected than the other. The dominant hand usually experiences symptoms first due to increased use. Each hand may require different management depending on symptom severity, which will be assessed during consultation.

Will I need to stop working during treatment?

Conservative treatments generally allow continued work with adjustments, such as wrist splints and regular breaks. After surgery, time off depends on job demands—office work may resume in 2–3 weeks, while manual work could require 6–8 weeks. Specific guidance will be provided by our specialist.

Is carpal tunnel syndrome related to computer use?

While prolonged computer use can contribute to carpal tunnel symptoms, it’s not the sole cause. Poor ergonomics, repetitive motions, and sustained wrist positions can be contributing factors as well. Many people who use computers develop symptoms due to improper workstation setup rather than computer use itself. Ergonomic adjustments and regular breaks can help reduce discomfort without needing to limit computer time.

What’s the success rate of carpal tunnel surgery?

Carpal tunnel release surgery generally provides significant relief of symptoms for appropriate candidates. The results depend on factors such as how long symptoms have been present, the severity of nerve compression, and following post-operative rehabilitation instructions. Early surgical intervention usually leads to better outcomes than waiting until severe nerve damage occurs.

Can carpal tunnel syndrome come back after treatment?

Recurrence after treatment is uncommon. Conservative treatments may require ongoing management to maintain symptom control. Some patients may develop symptoms in the other hand or experience different conditions mimicking CTS. Regular follow-ups help monitor your progress and address any new concerns promptly.
