Name

# Extensor Retinaculum

Pronunciation

(ek-sten-sor retn-ak-yO-lum)

Notes

The flexor retinaculum forms a space between it and the unerlying carpal bones called the carpal tunnel. I am sure most of you have heard of or have had the carpal tunnel syndrome. In this syndrome, the structures under the retinaculum are compressed by swelling caused by irritation and inflammation and the median nerve is weakened. If left untreated, major paralysis to the small muscles of the hand can occur.
