Introduction

Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome, characterized by compression of the median nerve at the wrist. It presents with symptoms such as pain, numbness, and weakness in the hand and fingers, often exacerbated by repetitive hand movements. This synthesis explores the etiology, diagnosis, and treatment of CTS, with a focus on occupational factors and management strategies.

Key Insights

Etiology and Risk Factors
- CTS is caused by compression of the median nerve at the wrist, with symptoms including pain, numbness, and weakness in the hand and fingers .
- Occupational factors, such as repetitive and forceful hand movements and the use of vibratory tools, are significant contributors to CTS .
- Other risk factors include anatomical, systemic, and individual factors, such as age, gender, and predisposing comorbidities .
Clinical Presentation and Diagnosis
- Common symptoms include nocturnal pain, paresthesias, and sensory disturbances in the median nerve distribution, often worsening with hand activity .
- Physical examination findings often include a positive Tinel's sign and Phalen's test, sensory loss, and in severe cases, thenar muscle atrophy .
- Diagnosis is confirmed through electrodiagnostic testing, including nerve conduction studies (NCS), which are the most sensitive and accurate techniques .
Management and Treatment
- Conservative management includes rest, splinting, and corticosteroid injections, which can provide symptom relief in many patients .
- Surgical intervention, such as the release of the transverse carpal ligament, is recommended for advanced cases or when conservative treatments fail. Both open and endoscopic surgical techniques are effective, with no clear superiority of one over the other .
- Post-surgical recovery and return to work lack standardized guidelines, highlighting the need for evidence-based recommendations.

Conclusion

Carpal tunnel syndrome is a prevalent condition, particularly among working-aged individuals, often linked to occupational activities. Diagnosis relies on clinical evaluation and electrodiagnostic testing. Management ranges from conservative approaches to surgical intervention, with both methods providing significant symptom relief. However, the need for standardized post-surgical recovery guidelines remains an area for further research.
