Upper Extremities Flashcards
Colles’ fracture
Fracture of the distal radius and ulnar styloid with posterior displacement
More frequent in older adults who fall on an outstretched hand
Smith’s Fracture
Fracture of the distal radius and ulnar styloid with anterior displacement
Also known as Reverse Colles’
Torus or Buckle fracture
Impacted fracture with a bulging periosteum
Most common fracture of the distal radius and ulnar in young children

Common wrist fractures
Colles’, smith’s, torus or buckle
Wrist projections
PA, PA Ob, Lateral, ulnar deviation
PA wrist
Flex elbow 90 degrees, fingers flexed under hand to make wrist and hand on same plane, CR perpendicular to IR and centered at the mid carpal area/ wrist, collimating to include metacarpals and about one inch of the distal radius and ulna
PA Oblique wrist
Flex elbow 90 degrees, straighten fingers, externally rotate hand so that it makes a 45 degree angle with the IR, CR perpendicular to IR and centered at the mid carpal area/ wrist, collimating to include metacarpals and about one inch of the distal radius and ulna
PA Oblique wrist evaluation criterial
Slight overlap of radius and ulna, trapezium and scaphoid demonstrated,
Lateral wrist
Flex elbow 90 degrees, fingers straight, medial side of arm down, thumb side up but thumb straight with other fingers, radial and ulnar styloid should inline with one another and superimposed, CR perpendicular to IR and centered at the mid carpal area/ wrist, collimating to include metacarpals and about one inch of the distal radius and ulna
Lateral wrist evaluation criteria
Proximal half of the metacarpals should be superimposed, radius and ulna should be superimposed, and carpals should be superimposed
PA ulnar deviation
Flex elbow 90 degrees, turn hand outward towards the CR perpendicular to IR and centered at the scaphoid, collimating to include metacarpals and about one inch of the distal radius and ulna
PA ulnar deviation evaluation criterial
Scaphoid demonstrated without foreshortening and adjacent articulations open, extreme ulnar deviation
Essential projections for the forearm
AP and Lateral
AP forearm
Hand is supinated, anterior side up, make sure arm and shoulder are the same plane, elbow needs to be extended, collimation needs to include elbow joint and wrist joint (wrist to distal humerus)
AP forearm criteria
Elbow joint partially open, wrist to distal humerus demonstrated, no elongation or foreshortening of the humeral epicondyles
Lateral forearm
Elbow flexed at 90 degrees, ulnar and radial styloid processes superimposed, entire upper limb in the same plane, collimated field includes wrist to distal humerus, CR enters at midpoint of the forearm
What does the shoulder girdle consists of?
Clavicle and scapula, which articulates with the head of the humerus, the manubrieum of sternum and each other
The function of the shoulder girdle is to…
connect the upper limb to the trunk of the body
Is the humerus considered to be apart of the shoulder girdle?
NO
What type of joint is the shoulder?
Diarthrodial classification by function, synovial classification by anatomy, ball and socket type capable of all motions
What bone lies just above the first rib and is classified as a long bone?
Clavicle
The clavicle has a lateral end and a medial end called what?
Lateral- acromial extremity
Medial - sternal extremity
