A retinaculum is a thickened fibrous band of fascia that functions to hold tendons in place as they pass over bony prominences or through fibro-osseous tunnels. Examples of retinacula include the extensor retinaculum, which holds the tendons of the extensor muscles in place as they pass over the dorsum of the wrist, and the flexor retinaculum, which holds the tendons of the flexor muscles in place as they pass through the carpal tunnel in the wrist.
