2. The hand and the wrist are the most active and
the most intricate parts of the upper extremity.
(Magee, David; Orthopedic Physical Assessment 4th Ed)
Vulnerable to injury and does not respond well to
serious trauma. (Magee, David; Orthopedic Physical Assessment
4th Ed)
In addition to being an expressive organ of
communication, the hand has a protective role
and acts as both a motor and a sensory organ,
providing information such as temperature,
thickness, texture, depth, and shape as well as
the motion of an object. (Magee, David; Orthopedic Physical
Assessment 4th Ed)

Blanching remains in the palm after pressure
is released from the artery. Can also be used

43. A 30 year old man involved in a fight, injured his middle finger and noticed slight flexion of DIP

4. Buddy strapping
In hand surgery which area is called no mans land:
1. Proximal phalanx
