Probability of Developing Carpal Tunnel Syndrome

Carpal tunnel syndrome (CTS) affects approximately 3-6% of the adult population, with about 400,000-500,000 carpal tunnel release surgeries performed in the US each year. It is the most common entrapment neuropathy (nerve compression) and a leading cause of work-related disability.

CTS occurs when the median nerve, which runs through the carpal tunnel in the wrist, becomes compressed. Risk factors include repetitive hand and wrist movements, pregnancy (temporary CTS occurs in about 30-50% of pregnancies), obesity, diabetes, thyroid disorders, rheumatoid arthritis, and female sex (women are 3 times more likely to develop CTS). Occupations with the highest risk include assembly line work, data entry, meatpacking, and construction.

Symptoms include numbness, tingling, and weakness in the hand (particularly the thumb, index, and middle fingers), often worse at night. Conservative treatment options include wrist splinting (especially at night), activity modification, anti-inflammatory medications, and corticosteroid injections. Carpal tunnel release surgery is one of the most common outpatient procedures and has a success rate of about 85-90% in relieving symptoms.
