Anatomical Snuffbox
The Anatomical Snuffbox (also known as the radial fossa), is a triangular depression found on the
lateral aspect of the dorsum of the hand. It is located at the level of the carpal bones, and best seen
when the thumb is extended.
In the past, this depression was used to hold snuff (ground tobacco) before inhaling via the nose
- hence it was given the name 'snuffbox'.
Content:
Radical artery and radical nerve
Scaphoid bone (from the floor of snuff box)
Cephalic vein
Clinical Importance:
The anatomical snuffbox is an important clinical region
When the hand is in ulnar deviation, the scaphoid becomes palpable within the
snuffbox.
This position enables the physician to palpate the bone to assess for a fracture.
The pulse of the radial artery can also be felt in the snuffbox.
Bleeding from anatomical snuff box due to injury to the ……….. Radial artery
Retinaculum
A retinaculum is a band of thickened deep fascia
around tendons that holds them in place.
It is not part of any muscle.
Its function is mostly to stabilize a tendon.
