What is the name of the joint found between the proximal and distal phalanges of the first digit?
| Question Answer | What is the most commonly fractured carpal bone? scaphoid | What carpal bones articulate with the base of the fifth metacarpal? Hamate | Which carpal bone is the smallest? pisiform | What is the name of the joint found between the proximal and distal phalanges of the first digit? Interphalangeal joint |

Where is the pronator fat stripe located?
Scaphoid fat stripe is located laterally to the scaphoid, the pronator fat stripe is located on
the lateral view of the wrist
. The anterior fat pad or stripe is located just anterior to the distal humerus.
Which is the most commonly fractured carpal bone?
Scaphoid fractures
are by far the most common of the carpal fractures, and account for 10 percent of all hand fractures and about 55 percent of all carpal fractures [1,4-8]. The triquetrum is the second most common carpal fracture, comprising about 21 percent.
Which routine projections are required for a study of the forearm?
| Question Answer | which basic projections are required for a study of the forearm? AP and lateral | For a forearm study, the technologist needs to include only the joint closest to the site of the injury? (T or F) False |

Which carpal bone is most medial in the proximal row?
Lastly,
the pisiform bone
is the most medial proximal carpal bone from a palmar stance. It is also the smallest of all the carpal bones and classified as a sesamoid bone. Its dorsal surface is faceted, allowing it to articulate with the ventral surface of the triquetral bone.
Which joint is present between Atlas and axis?
The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates. The joint between the atlas and axis is a pivot type of joint. It allows the head turn from side to side. It is also called
the atloaxoid joint
.
Which movement of the wrist will open up the interspaces on the ulnar side of the wrist quizlet?
The PA projection with radial deviation best
demonstrates the interspaces on the ulnar side of the wrist between the lunate, triquetrum, pisiform, and hamate bones. Which alternative projection to the routine PA wrist best demonstrates the intercarpal joint spaces and wrist joint?
What is the pronator quadratus?
Pronator quadratus is
a quadrangular, thin, short and flat muscle lying within the anterior compartment of forearm
. … These three muscles are overlaid by the superficial group of forearm flexors. Pronator quadratus extends across the distal parts of the radius and ulna.
What is pronator fat pad?
Emcore. The pronator Quadratus sign is a sign seen on the lateral X-ray of the wrist/forearm and can assist in diagnosing an occult radial fracture. The line represents a fat pad that
lies parallel to the distal radius
, over the fascial covering between pronator quadratus and flexor digitorum profundus muscle.
How do you know if you have a carpal fracture?
- Severe pain that might worsen when gripping or squeezing or moving your hand or wrist.
- Swelling.
- Tenderness.
- Bruising.
- Obvious deformity, such as a bent wrist.
Which bone is most commonly fractured?
The collarbone, otherwise known as the clavicle
, is the most commonly broken bone, thanks in large part to where it’s positioned. Located between the shoulder blade and upper ribcage, it attaches the arm to the rest of the body.
How do you memorize the carpal bones?
- Some – Scaphoid.
- Lovers – Lunate.
- Try – Triquetrum.
- Positions – Pisiform.
- That – Trapezium.
- They – Trapezoid.
- Can’t – Capitate.
- Handle – Hamate.
Why should a forearm never be taken as a PA projection?
Why should a forearm never be taken as a PA projection?
Causes the proximal radius to cross over the ulna
. In what position should the hand be for an AP elbow projection?
Which projection of the best demonstrates the radial head and neck without superimposition?
The elbow external oblique view
is an additional projection of the elbow often used to better demonstrate the radial head free from superposition.
Which projection of the forearm requires the elbow flexed 90 degrees?
A
lateral radiograph
of the elbow requires the elbow to be flexed 90 degrees with the forearm and humerus laying flat on the table and the image receptor, ulnar side down on the receptor, and thumb/radial side up.
