Carpal Tunnel Syndrome: Diagnosis, Treatment, and Management
Introduction to Carpal Tunnel Syndrome
Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome, affecting a significant portion of the population worldwide. It is characterized by the compression of the median nerve at the wrist, leading to symptoms such as pain, numbness, tingling, and weakness in the hand and arm . The condition is prevalent among middle-aged individuals, particularly women and office workers, and can significantly impact quality of life and work productivity .
Clinical Features and Diagnosis of Carpal Tunnel Syndrome
Symptoms and Physical Examination
Patients with CTS typically experience numbness and tingling in the thumb, index, middle, and ring fingers, which often worsens at night or after excessive hand activity. Pain may also radiate from the wrist to the shoulder. Physical examination findings commonly include a positive Tinel sign and a positive wrist-flexion test.
Diagnostic Techniques
Diagnosis of CTS is primarily based on patient history and physical examination. However, electrodiagnostic testing and nerve imaging can provide additional information about the extent of axonal involvement and structural changes . Sensory and motor nerve conduction studies (NCS) are the most sensitive and accurate techniques for documenting neurophysiologic abnormalities in the median nerve. Other methods, such as vibrometry threshold testing and two-point discrimination, are less sensitive but still used in clinical practice.
Pathophysiology of Carpal Tunnel Syndrome
The pathophysiology of CTS involves increased pressure within the carpal tunnel, which impairs microvascular circulation in the median nerve, leading to demyelination and axonal loss. Factors such as wrist flexion and extension, finger flexion, and repetitive hand movements can exacerbate the condition by further increasing tissue pressure in the tunnel .
Treatment Options for Carpal Tunnel Syndrome
Non-Surgical Treatments
Non-surgical management of CTS includes wrist splinting, corticosteroid injections, and neurodynamic techniques. Splinting and corticosteroid injections are effective in providing symptom relief, particularly in mild to moderate cases . Neurodynamic techniques, which promote median nerve gliding during upper limb movements, have shown significant benefits in reducing symptom severity, pain, and motor latency, while improving nerve conduction velocities.
Surgical Treatments
When non-surgical treatments fail to provide lasting relief, surgical intervention may be necessary. The most common surgical procedure is the complete section of the transverse carpal ligament, which relieves pressure on the median nerve and alleviates symptoms . Both open and endoscopic carpal tunnel release surgeries are effective, with no significant difference in outcomes at three months post-operation .
Conclusion
Carpal tunnel syndrome is a prevalent and impactful condition that requires accurate diagnosis and effective management to improve patient outcomes. While non-surgical treatments such as splinting, corticosteroid injections, and neurodynamic techniques can provide significant relief, surgical intervention remains a viable option for more severe cases. Ongoing research and clinical trials are essential to further refine diagnostic methods and treatment strategies, ultimately enhancing the quality of care for individuals with CTS.
