Which abnormal condition is caused by compression of the median nerve?

• A. Tennis Elbow
• B. Ganglion Cyst
• C. De Quervain's Tenosynovitis
• D. Carpal Tunnel Syndrome

Answer: (D)

Compression of the median nerve at the wrist leads to Carpal Tunnel Syndrome. When the nerve is squeezed inside the carpal tunnel, it causes numbness, tingling, and sometimes weakness in the areas the median nerve supplies—the thumb, index finger, middle finger, and the radial half of the ring finger. Symptoms are often worse at night, and patients may notice difficulty with thumb opposition and grip due to weakness of the thenar muscles. This specific pattern of sensory loss and motor weakness reflects median nerve compression in the carpal tunnel, which is distinct from elbow tendinopathies or tendon-related wrist conditions like De Quervain’s tenosynovitis or ganglion-related mass effects.
