What Is Carpal Tunnel Syndrome? What Are the Treatment Methods?

Carpal Tunnel Syndrome

Carpal tunnel syndrome is a condition that causes various symptoms in the hand, wrist and fingers as a result of nerve compression within the carpal tunnel located in the wrist. This syndrome can lead to symptoms such as pain, numbness, weakness and muscle atrophy in the hand and wrist due to pressure on the nerve. Various treatment methods, including surgery, are available for this condition.

What Is Carpal Tunnel Syndrome?

The carpal tunnel is a structure located beneath the carpal bones of the wrist, containing the wrist flexor tendons and the median nerve. The median nerve is the nerve that provides sensation to the hand and controls its muscles. Within the carpal tunnel, in addition to the median nerve, there are tendons, ligaments and adipose tissue. The upper part of the carpal tunnel has a roof formed by bone and ligaments, while its lower part is covered by the wrist flexor tendons.

Carpal tunnel syndrome is the compression of the median nerve caused by narrowing of the tunnel or pressure on the structures within it. This narrowing usually results from factors such as tendon inflammation, bone spurs or cysts. The narrowed tunnel exerts pressure on the median nerve and disrupts its normal conduction. Symptoms of nerve compression develop due to the median nerve pressure caused by the narrowed tunnel. These symptoms generally increase at night or during repetitive hand movements.

What Are the Symptoms of Carpal Tunnel Syndrome and How Is It Diagnosed?

Symptoms result from compression of the median nerve within the carpal tunnel and impairment of nerve conduction. The most common symptoms are tingling, numbness and loss of sensation in the hand, wrist and fingers. These symptoms may increase especially at night or after waking up in the morning. A feeling of weakness in the hand and difficulty gripping are also among the commonly seen symptoms. Pain may start especially in the hand and wrist and spread to the arm and shoulder. In some patients, a feeling of discomfort and a burning sensation moving upward from the wrist may also occur. Carpal tunnel syndrome symptoms can affect daily activities. Problems such as difficulty grasping objects, decreased hand dexterity or difficulty gripping may occur. The severity of symptoms varies from person to person. Carpal tunnel syndrome symptoms include:

Tingling in the hand, wrist and fingers

Feeling of numbness

Loss of sensation in the hand

Weakness

Pain

Difficulty gripping

Decreased hand dexterity

Burning sensation (moving upward from the wrist)

Pain Spreading to the Arm and Shoulder

The diagnosis of carpal tunnel syndrome is made with tests such as medical history, physical examination, electromyography (EMG) and nerve conduction velocity testing.

During the examination, the patient's symptoms and medical history are evaluated. The doctor checks for tenderness in the hand, wrist and arm areas, and assesses nerve function and muscle strength. Tests used in diagnosis include the Phalen test, Tinel test and needle electromyography (EMG). The Phalen test involves the patient pressing the backs of the hands together and flexing the fingers downward. In this position, pain, tingling or numbness may indicate carpal tunnel syndrome. The Tinel test checks whether tingling or numbness is triggered by light tapping over the wrist at the point where the median nerve is affected. Needle EMG is used to evaluate nerve conduction and muscle activity. This test helps determine the severity and location of nerve compression.

Imaging methods may include radiography (X-rays), magnetic resonance imaging (MRI) and ultrasonography. Radiography is used to evaluate bone structure and structural abnormalities in the carpal tunnel. MRI provides detailed images of nerves and soft tissues, helping to observe nerve compression or other possible causes. Ultrasonography can be used to evaluate the structure of the carpal tunnel and the condition of the median nerve.

What Are the Causes and Risk Factors of Carpal Tunnel Syndrome?

There are various factors that can cause carpal tunnel syndrome. Repetitive movements using the hand and wrist, prolonged exposure to vibration, or overuse can lead to carpal tunnel syndrome. Such activities irritate the tissues of the hand and wrist and can cause nerve compression. Hormonal changes such as pregnancy or menopause can also cause fluid retention in the body, increasing pressure within the carpal tunnel and contributing to nerve compression. Traumatic conditions such as hand and wrist injuries, fractures, sprains or ligament injuries can increase the risk of carpal tunnel syndrome. Carpal tunnel syndrome is sometimes associated with various medical conditions. These include diabetes, rheumatoid arthritis, hypothyroidism, obesity and kidney failure.

Carpal tunnel syndrome is also closely associated with certain occupations and activities. Office workers, industrial workers, musicians, athletes and manual laborers are at risk of carpal tunnel syndrome due to repetitive movements.

What Are the Treatment Methods for Carpal Tunnel Syndrome?

Treatment options may vary depending on the severity and duration of symptoms and the patient's health condition. Surgical treatment may be required especially if symptoms are severe or if other treatment methods have been ineffective. Methods such as splinting, medications and physiotherapy are used in the treatment of carpal tunnel syndrome. Carpal tunnel syndrome treatment options include:

Splinting: Use of a wrist splint or brace may help relieve the symptoms of carpal tunnel syndrome. These splints stabilize the wrist, reducing pressure on the nerve and limiting wrist movements, which helps the nerve to heal.

Medications: Nonsteroidal anti-inflammatory drugs or corticosteroid injections may be prescribed by a doctor to relieve the symptoms of carpal tunnel syndrome. Nonsteroidal anti-inflammatory drugs reduce pain and inflammation, while corticosteroid injections can reduce inflammation locally. These medications may temporarily relieve symptoms but do not have curative properties.

Physiotherapy: Physiotherapy is a treatment option used to manage the symptoms of carpal tunnel syndrome and improve hand and wrist function. Physiotherapy programs may include hand and wrist exercises, strengthening of hand muscles, nerve mobilization techniques and posture correction. These exercises and techniques may help reduce nerve compression, relieve symptoms and improve hand and wrist function.

Open Surgery: Open surgery is a method used in the treatment of carpal tunnel syndrome. In this procedure, an incision is made in the wrist area and the roof of the carpal tunnel is cut to relieve pressure over the tunnel. It aims to relieve symptoms and allow the nerve to heal by reducing pressure on the nerve.

Endoscopic Surgery: Endoscopic surgery is a newer method in the treatment of carpal tunnel syndrome. In this procedure, smaller incisions are made using an endoscope and fine surgical instruments. The endoscope allows the surgeon to visualize the carpal tunnel inside the wrist and reduce pressure on the nerve. Endoscopic surgery generally causes less tissue damage while allowing a shorter recovery process. The choice between open surgery and endoscopic surgery depends on factors such as the severity and duration of the patient's symptoms and general health condition. The surgical method to be used is determined by taking into account the surgeon's experience and patient preferences.

How Is Rehabilitation Performed After Carpal Tunnel Syndrome Treatment?

The rehabilitation process is among the important factors affecting the success of treatment. The patient's adherence to the treatment plan, regular exercise and compliance with the recommended treatment process closely affect the course of treatment. The rehabilitation process after carpal tunnel syndrome treatment includes physiotherapy, hand exercises, pain management and ergonomic adjustments.

Physiotherapists apply special exercise programs and therapy techniques to improve patients' hand and wrist function. These exercises and therapies aim to increase muscle strength, improve range of motion and restore hand and wrist function. After carpal tunnel syndrome treatment, patients are generally recommended hand exercises that they can do at home.

These exercises help strengthen hand muscles, increase mobility and support nerve recovery.

Pain management after treatment is also an important element. Pain relievers and, when necessary, anti-inflammatory drugs may be prescribed by a doctor. After carpal tunnel syndrome treatment, it is also important to make ergonomic adjustments during work and daily activities. Using ergonomic keyboards, mice and other equipment can help keep the wrists in the correct position. Proper posture and working positions should also be supported in the work environment.

What Happens in the Advanced Stages of Carpal Tunnel Syndrome?

If carpal tunnel syndrome is not treated, various complications can arise and serious problems may be seen in advanced cases. Untreated carpal tunnel syndrome can cause chronic nerve compression, nerve injury and damage. In this case, symptoms such as persistent tingling, numbness, loss of sensation and weakness in the hand and wrist may become permanent. In advanced carpal tunnel syndrome, nerve damage can lead to muscle weakness. The hand and finger muscles may weaken, and difficulty gripping and decreased hand dexterity may be seen. This condition can negatively affect daily life. Carpal tunnel syndrome symptoms may increase especially during sleep at night. Due to pain, tingling and numbness in the hands and wrists, sleep quality may be adversely affected. In cases that are untreated, or advanced cases that cannot be treated, surgical intervention may be required. Surgical options are used to relieve symptoms and to ensure the nerve is no longer kept under pressure. It is important for people with carpal tunnel syndrome symptoms to seek medical help for early diagnosis and treatment.

What Measures Should Be Taken to Prevent Carpal Tunnel Syndrome?

To prevent carpal tunnel syndrome, it is important to create an ergonomic work environment, pay attention to hand and wrist movements, manage stress, use hand heating and cooling methods, quit smoking and maintain general health. These measures may help reduce the risk of developing carpal tunnel syndrome.

Creating an ergonomic work environment is an important factor in preventing carpal tunnel syndrome. To ensure a correct sitting position, an adjustable chair and desk should be used, with back support and wrists aligned naturally. Ergonomic keyboards and mice should be preferred to keep the wrists naturally aligned. At the same time, the monitor should be at eye level and at an appropriate distance so that tension in the neck and shoulders is reduced. Paying attention to hand and wrist movements is important in preventing carpal tunnel syndrome.
