Study Notes
Carpal Tunnel Syndrome (CTS)
- Compression of the median nerve in the wrist's carpal tunnel leads to nerve-related symptoms.
- Tinel's sign is characterized by tingling or pain elicited by tapping over the median nerve.
- CTS affects the thumb, index finger, middle finger, and half of the ring finger due to median nerve innervation.
- Tingling of the small finger is not typical in CTS, as it is innervated by the ulnar nerve.
Causes
- Causes of CTS include repetitive hand movements, wrist anatomy variations, and conditions like arthritis or diabetes.
Symptoms
- Common symptoms include numbness, tingling, and weakness in the affected fingers.
- Symptoms often worsen at night or with activities involving hand use.
Nerve and Symptom Distribution
- Symptoms are distributed along the areas innervated by the median nerve.
- Pain may radiate to the forearm or shoulder in severe cases.
Diagnostic Signs
- Phalen's maneuver leads to symptom reproduction when holding the wrist in flexion.
- Hand symptoms worsen during specific activities, indicating CTS.
Diagnosis
- Diagnosis often includes clinical evaluation, symptom history, and physical tests.
- An electromyography (EMG) study may be required for confirmation of nerve compression.
Treatment
- Initial treatments may involve wrist splints, anti-inflammatory medications, and activity modification.
- Severe cases or those unresponsive to conservative treatment may require surgery.
Insurance and Diagnosis
- Insurance may require EMG confirmation prior to surgical intervention approval.
