Carpal tunnel syndrome
Definition: Carpal tunnel syndrome is a common condition that causes pain, numbness, and tingling in the hand and wrist. It occurs when the median nerve, which runs along the palm side of the wrist through a narrow passage called the carpal tunnel, becomes compressed.
Causes: Several factors can contribute to carpal tunnel syndrome, including:
Repetitive hand movements: Jobs or activities that involve repetitive hand motions, forceful gripping, or prolonged vibration can irritate the tendons around the median nerve, leading to swelling and compression.
Anatomy: Some people naturally have a smaller carpal tunnel, putting them at higher risk for nerve compression.
Fluid retention: Conditions causing fluid retention, like pregnancy, obesity, or certain medications, can increase pressure in the carpal tunnel and compress the median nerve.
Arthritis: Rheumatoid arthritis or osteoarthritis in the wrist can contribute to swelling and narrowing of the carpal tunnel.
Signs and Symptoms:
Numbness, tingling, or burning sensation in the thumb, index finger, middle finger, and half of the ring finger (areas innervated by the median nerve).
Pain or aching in the palm or wrist, often radiating up the forearm.
Weakness or clumsiness in the hand, making it difficult to grasp objects.
Symptoms often worsen at night or with prolonged hand use and may improve with shaking the hand or hanging it down.
Treatment: Treatment for carpal tunnel syndrome depends on the severity and aims to relieve pressure on the median nerve. Options may include:
– Immobilization: Wearing a wrist splint at night can help prevent further nerve compression during sleep.
– Activity modification: Avoiding activities that aggravate symptoms might be necessary.
– Steroid injections: Corticosteroid injections can reduce inflammation around the median nerve.
– Surgery: In severe cases, carpal tunnel release surgery may be performed to create more space for the median nerve.
