What happens when median nerve is compressed?

What causes the median nerve to be compressed?

Carpal tunnel syndrome CTS is the most common of the median nerve entrapments. The carpal tunnel is a narrow fibro-osseous tunnel through which the median nerve passes, along with nine tendons. An increase in the volume of the tunnel contents or a decrease in the size of the tunnel can compress the median nerve.

What is the differential diagnosis of median nerve compression?

This resident’s case problem details the evaluation and differential diagnosis process for median nerve entrapment resulting from forceful and repetitive pronation/supination motions. Median nerve compression syndromes include pronator syndrome, anterior interosseous nerve syndrome, and carpal tunnel syndrome.

How is median nerve injury diagnosed?
