Rad 210 Upper Limb Laisha Hill Flashcards
The most distal bones of the hand are
phalanges
What bones make up the palm of each hand
metacarpals
The thumb has only two phalanges, so the joint between them is called what
interphalangeal (IP) joint.
The joint between the first metacarpal and the proximal phalanx of the thumb is called what
first metacarpophalangeal (MCP) joint.
from the most distal portion of each digit, the joints are
distal interphalangeal (DIP) joint, followed by the proximal interphalangeal (PIP) joint, and, most proximally, the MCP joint.
At the proximal end, the metacarpals articulate with the respective carpals and are called
carpometacarpal (CMC) joints
The five metacarpals articulate with specific carpals as follows:
- First metacarpal with trapezium
- Second metacarpal with trapezoid
- Third metacarpal with capitate
- Fourth and fifth metacarpal with hamate
soft tissues, such as certain accumulations of fat called
fat pads, fat bands, or stripes
is located deep within the olecranon fossa and normally is not visible on a negative elbow examination where
The posterior fat pad
supinator fat stripe
a long, thin stripe just anterior to the proximal radius.
The third carpal is the
triquetrum(tri-kwe′-trum), which has three articular surfaces and is distinguished by its pyramidal shape and anterior articulation with the small pisiform.
lunate
is the second carpal in the proximal row; it articulates with the radius.
the smallest of the carpal bones, is located anterior to the triquetrum and is most evident in the carpal canal or tangential projection
pisiform
what do steve the left the party to take carol home
Scaphoid,Lunate,Triquetrum,Pisiform,Trapezium, Trapezoid,Capitate, Hamate

The wrist joint is an
ellipsoidal type joint and is the most freely movable, or diarthrodial, of the synovial classification
the posterior fat pad is located where ?
deep within the olecranon fossa and normally is not visible on a negative elbow examination
The supinator fat stripe location
is a long, thin stripe just anterior to the proximal radius. It may indicate the diagnosis of radial head or neck fractures that are not obviously apparent.

the correct term for the wrist is scaphoid or navicular
scaphoid , although sometime is called navicular like the tarsal in foot
which bone of the forearm is more stationary
the ulna. remember the radius rotates around.
the tapered constricted area just under the head of the radius is called the?

olecranon can be palpated where ?
the posterior aspect of the elbow joint
coronoid process is located where
the one located inferior to the olecranon
the expanded distal end of the humerus

an upper limb cast requires ___ exposure
increased, the increase depends on thickness and type of cast
