Carpal Tunnel Syndrome (CTS): Understanding the Condition
Carpal tunnel syndrome (CTS) occurs when the median nerve is compressed in the wrist, causing pain, numbness, and weakness. Early diagnosis is crucial for effective treatment.
2.1 Pathophysiology of CTS
Carpal tunnel syndrome occurs due to compression of the median nerve within the carpal tunnel, leading to nerve ischemia and inflammation. The tunnel, formed by bones and ligaments in the wrist, narrows when swelling or structural changes occur. Repetitive motion, trauma, or fluid retention can trigger this compression, disrupting nerve function and causing symptoms like numbness, tingling, and weakness. Ultrasound can detect morphological changes such as nerve thickening or ligament hypertrophy, aiding in early diagnosis and targeted treatment.
2.2 Clinical Presentation and Diagnosis
Carpal tunnel syndrome typically presents with numbness, tingling, and weakness in the thumb, index, and middle fingers, often worsening at night. Clinical diagnosis involves Tinel’s and Phalen’s tests, while ultrasound imaging confirms median nerve compression by revealing nerve thickening, increased cross-sectional area, and transverse carpal ligament hypertrophy. These morphological changes are critical for accurate diagnosis and guiding interventions like ultrasound-guided carpal tunnel release.
